Global warming endangers South American water supply

Chile and Argentina may face critical water storage issues due to rain-bearing westerly winds over South America's Patagonian Ice-Field to moving south as a result of global warming.

A reconstruction of past changes in the North and Central Patagonian Ice-field, which plays a vital role in the hydrology of the region, has revealed the ice field had suddenly contracted around 15,000 years ago after a southerly migration of westerly winds.

This migration of westerly winds towards the south pole has been observed again in modern times and is expected to continue under a warming climate, likely leading to further ice declines in this area affecting seasonal water storage.

"We found that precipitation brought to this region by Southern Hemisphere westerlies played an important role in the glaciation of the North Patagonian Ice-Fields," said Dr Chris Fogwill from the Climate Change Research Centre at the University of New South Wales. 

"Our research has shown this ice-field significantly reduced in size when those winds moved southwards."

The North Patagonian Ice-field is vital to maintain seasonal water storage capacity for Argentina and Chile.

"Worryingly, this study suggests the region may well be on a trajectory of irreversible change, which will have profound impacts on agriculture and the increasing dependency on hydroelectric power in Chile and Argentina," Dr Fogwill said.

New Explanations Sought for Dolphin Strandings

In waters from Florida to the Caribbean, dolphins are showing up stranded or entangled in fishing gear with an unusual problem: They can't hear.

A study has found that more than half of stranded bottlenose dolphins and more than a third of stranded rough-toothed dolphins had severe hearing loss. The animals' hearing impairment may have been a critical factor in their strandings. The causes of hearing loss in dolphins aren't always clear, but aging, shipping noise and side effects from antibiotics could play roles.

Whether the hearing loss is causing the dolphin strandings — for instance, by steering the marine mammals in the wrong direction or preventing them from finding food — remains an open question.

A wildfire raging in the Sierra National Forest in southern California since July 22 has burned through over 11,000 acres and continues on a path of destruction as firefighters continue attempts at containment.

Four wildfires are actively burning in western Montana and have led to some evacuations and road and trail closures, having scorched over 36 square miles.

Lightning late last week touched off dozens of fires in southwest Oregon near Glendale. Most of the small ones were contained, and some merged into larger fires that make up the Douglas Complex. Those fires have burned 21,000 acres, or nearly 33 square miles, and were just 2 percent contained as of Monday afternoon. Seventy-five houses have been evacuated and another 40 are on evacuation alert.

Roundup of Global Volcanic Activity:

Shiveluch (Kamchatka): Activity has been elevated during the past days. Several explosions and / or dome collapse events have sent ash plumes to about 20,000 ft (6 km) elevation during the past days.

Sakurajima (Kyushu, Japan): Activity remains high - explosions occur at more-than-usual frequency from the Showa crater. An eruption on 27 July produced an ash plume rising to 18,000 ft (5.7 km) altitude, i.e. an eruption plume about 4.5 km tall.

Karangetang (Siau Island, Sangihe Islands, Indonesia): VSI has decreased the alert level from 3 (Siaga, Alert) (since 8 August 2011) back to 2 (Waspada, watch). No lava emissions/ejections have been observed since 7 July and seismic activity has been decreasing over the past weeks. No hot spot is visible on satellite imagery.

Ambrym (Vanuatu): A seismic swarm at the volcano was detected on 26 July, but no evidence of unusual activity at the surface has been detected. The lava lakes inside Benbow and Marum remain active.

White Island (New Zealand): The seismic crisis ended on 28 July with no eruption. Degassing remains elevated and incandescence is still visible from the dome in the crater.

Tungurahua (Ecuador): During the past days, a further increase in activity of the volcano occurred, characterized by the generation of large explosions and a constant ash eruption column, and several small to big explosions that generated strong vibrations and rattled windows in villages near the volcano. An eruption at 07:23 (local time) on 28 July generated a small pyroclastic flow that affected the upper north and north east flank of the volcano. Constant ash emissions produce a an ash column of up to 1.5 km height, drifting westwards. Ash fell in the town of Mocha.

New Theory on Major Earthquakes

A widely accepted theory about earthquakes has received a shakeup.

A team of geologists studying the San Andreas fault near Los Angeles found that bigger earthquakes aren't necessarily preceded by longer periods of inactivity on the fault. The going wisdom about earthquakes is that the longer a fault goes without a major earthquake, the bigger the quake will be when it finally strikes. The theory seems particularly apt for the San Andreas fault, which marks the boundary between two tectonic plates. As the Pacific plate moves northward relative to North America at about 4.5 cm per year, friction stops the fault from slipping. The longer that strain jacks up, the farther the plates will jolt when they finally let go and the larger the resulting earthquake will be. Or so the thinking went.

But a group found that the theory doesn't hold up for the segment of the fault near the southern California town of Wrightwood.

The team's analysis provided the most complete long-term record of activity for any fault in the world. And it contradicts the conventional wisdom: Shorter quiet periods of less than a century were generally followed by larger earthquakes, and longer periods of several hundred years preceded smaller quakes. Although this appears counterintuitive, the larger pattern is more logical. It appears that strain is not released entirely with each earthquake but continues to accumulate through four or five or more earthquake cycles. Finally, the strain is released by one big quake or a cluster of smaller shocks.

The authors caution that they don't know yet if the activity at the Wrightwood fault segment is typical of the entire San Andreas fault or of faults in general. But if it is, the research could change the way scientists estimate the probability of earthquakes.

Human Nature

Humans Not Natural Warriors

New studies of hunter-gatherer societies finds that warfare is not in human nature, but is a relatively new behavior that emerged from "civilized" cultures.

It is not in human nature for our species to make war, according to new research published in the journal Science.

Some scholars say that humankind inherited the inclination to wage war from its closest relative the chimpanzee, which exhibits a kind of war between groups.

But two researchers from Finland’s Abo Akademi University say that’s not the case and believe war developed with the rise of modern civilization, which caused conflicts over resources such as agriculture and livestock.

There is very little archeological evidence of war in our pre-civilized past.

So the researchers looked at modern-day hunter-gatherer people without livestock or the social class divisions that developed with the rise of civilization.

“When we looked at all the violent events about 55 percent of them involved one person killing another. That's not war,” said Fry. “When we looked at group conflicts, the typical pattern was feuds between families and revenge killings, which is not war either.”

Only a very small number of more organized killings comparable to war were found, and almost all of them were in one of the 21 groups studied.

The researchers conclude that some of the most “primitive” peoples on Earth were actually quite peaceful compared to modern, developed nations.

Global Warming

Greenhouse Gas Pollution Greening World's Deserts

Increased levels of atmospheric carbon dioxide from the burning of fossil fuels are causing deserts of the world to bloom with new green foliage, according to a new study. Randall Donohue, from Australia’s Commonwealth Scientific and Industrial Research Organization, used satellite observations from the past 30 years and found green foliage increased in arid regions during that period.

Higher levels of CO2 help the leaves during photosynthesis, the process by which green plants convert sunlight into sugar.

The increased greenhouse gas allows the plant to extract more carbon from the air, lose less water to the air or both, according to the study.

“While a CO2 effect on foliage response has long been speculated, until now it has been difficult to demonstrate,” said Donohue.

“Our work was able to tease-out the CO2 fertilization effect by using mathematical modeling together with satellite data adjusted to take out the observed effects of other influences such as precipitation, air temperature, the amount of light and land-use changes," said Donohue.

The findings were published in the journal Geophysical Research Letters.

Satellite data shows the amount that foliage cover has changed around the world from 1982 to 2010.

Paralyzed Ravens and Crows in Canada

Ravens and crows in eastern British Columbia are being afflicted by a mysterious paralysis that has left at least dozens dead.

Wildlife rehabilitation expert Leona Green said the first reports of the mysterious avian ailment started coming in from around the Peace Region from Fort St. John to Tumbler Ridge in late May.

“They are all feathered out, there’s no wing damage and they seem quite bright, and if you feed them by hand they will eat,” Green told the Vancouver Sun. “But their legs are completely paralyzed and their claws are clubbed with no feeling from their spines to their legs.”

She added that without the use of their legs, they can’t launch themselves into flight.

It’s feared the birds are suffering from the effects of West Nile virus, of which they are especially susceptible.

University of B.C. professor Patrick Mooney, who specializes in biodiversity and urban birds, said the deaths of such birds can act as an early warning system that the virus — which also affects humans — has arrived.

Ketoi (Kurile Islands, Russia): SVERT raised the alert level to yellow after a weak thermal anomaly has been detected on satellite data at the summit of the volcano. No other details about possible activity are currently known.

White Island (New Zealand): Following increased tremor including numerous earthquakes, and increased gas-steam emissions from the crater lake, the alert level of the volcano was raised to yellow again. According to Brad Scott of GNS Science, the crater produced "audible jets of gas" and "broader expanding bubbles of dark lake sediments and debris" throwing material 20-30 meters into the air.

Veniaminof (Alaska Peninsula, USA): From AVO's weekly activity update: "Nearly continuous, gradually fluctuating volcanic tremor and occasional explosions have been observed in seismic data from Veniaminof Volcano throughout the past week. Elevated surface temperatures at the intracaldera cone also have been observed in satellite data throughout the past week. When viewing conditions permit, incandescence at the cone has been observed in night-time web camera views. Day time web camera views also showed that low-level ash and steam emissions have continued throughout the week. A pilot report from 8:00 AM AKDT July 25 described an ash plume to 200-300 feet above the erupting cone and dispersing 15 miles to the south and a "river of lava" flowing from the intracaldera cone.

Arctic Cyclone Tears Up Sea Ice

Arctic scientists are watching in awe this week as a raging summer cyclone tears up what could become a record amount of rotting northern sea ice.

Arctic cyclones are driven by low-pressure systems in which winds of up to 100 km/h blow counter-clockwise in a spiral more than 1,000 kilometres across. They occur in both winter and summer, but are usually stronger in winter. Cyclones are not unusual in the Arctic, but seem to be changing in recent years. "These cyclones are not getting more frequent, but they are getting deeper -- which means stronger."

And they're getting harder on sea ice, which they break up through wave action associated with high winds and through rainfall, which darkens the ice and makes it absorb more solar energy. The storms also bring up water from the depths, which is actually warmer than surface water.

Cyclones can destroy large amounts of ice very quickly. "In 2009, we actually documented one of these events in which large, multi-year ice floes - Manhattan-sized - broke up in a matter of minutes." Last year, a particularly powerful cyclone is thought to have wiped out 800,000 square kilometres of ice. That contributed to record low sea-ice levels at the end of the 2012 melt year.

This year's storm over the Beaufort Sea formed about mid-week and is expected to die out on the weekend. It isn't as strong as last year's, but the ice is thinner and weaker. As well, the ice has already been pummelled by earlier storms. "The effects of (the storm) are nowhere near what we saw last August. But because the ice is thinner and it's already been pre-conditioned, and because there's less volume, it's much more vulnerable to impacts from this sort of thing."

The ice is getting so weak that new categories have had to be created for it. "We have a whole new class of sea ice in the Arctic, which we're calling 'decayed ice. We started seeing it in 2009. It's extremely weak." Changing sea-ice cover is increasingly being linked to southern weather patterns. The jet stream, which strongly influences weather at mid-latitudes, is driven by temperature differences between the Arctic and the equator, a difference that shrinks with the sea ice. Ice coverage is slightly about last year's record low but still well below the 30-year average.

Much remains unknown about the role of Arctic cyclones in the annual freeze-thaw cycle. Back when the sea was thick and lasted for years, cyclones tended to spread the ice out and actually increase its extent. Now, when ice gets spread out, it simply breaks up and disappears. "As our ice cover has thinned, some of our old rules are changing...This year has been very stormy. The month of August is definitely one to watch in the Arctic."

CDC Warns Of Rare Parasite Outbreak - USA

Centers for Disease Control and Prevention (CDC) officials are warning about potentially tainted produce that may have caused sickness in over 250 people across several US states.

The produce, which would have been shipped across state lines, is believed to have been contaminated with a rare parasite known as cyclospora. Almost 120 people have reportedly tested positive for the rare protozoan in Iowa, an additional 65 tested positive in Texas and another 68 in Nebraska, according to state officials. Several other cases have been reported in Wisconsin, Illinois and Kansas, although the Illinois case may yet be traced back to Iowa.

Officials have yet to formally identify a source for the illnesses. Cyclospora are not known to thrive in the US – making the possibility that imported produce may be the culprit highly likely.

Fish Die From Oxygen Starvation in England

A large amount of fish found dead in the lower Lea river and surrounding waterways were starved of oxygen.

The fish were spotted at various locations along the river, including Springfield Marina and Lea Bridge Weir pool in Walthamstow.

Recent hot weather reduced oxygen levels in the river, the Environment Agency said.

And storms on Monday night, which swept toxins from nearby roads into the river, meant oxygen levels were further depleted.

Fisheries officers from the agency worked through the night carrying out work to return levels to normal by running water through locks and pumping oxygen into the water at Three Mills Boatyard.

The agency reported that oxygen levels have risen around 25 per cent in the area, creating a refuge for fish including bream, perch, pike and roach.

Drought

New Zealand Drought

The 2012-13 drought has been confirmed as the worst in nearly 70 years for large parts of the country.

An assessment published today said the dry conditions had been unusually widespread, with a severity similar to that of 1945-46.

Although drought conditions had dissipated with the onset of winter, and many farms had started to recover following good autumn conditions, the economic and social impact of the drought continued to be felt around the country. Recent snow made it harder for farmers to see themselves through the winter and manage feed supply and pastures.

Roundup of Global Volcanic Activity:

Stromboli (Eolian Islands, Italy): Activity has been at relatively low to moderate levels recently. Explosions of small to medium size occur regularly from the "usual" (mainly the eastern and western) vents.

Tolbachik (Kamchatka): KVERT reports no changes in the ongoing mainly effusive eruption; tremor has remained stable (3.3 mcm/s). No significant changes were reported for either of the other currently erupting / restless Kamchatkan volcanoes:

Chirinkotan (Northern Kurils): A thermal hot spot and steam plume remain visible on satellite images (when there is no cloud cover), indicating that some activity continues at the remote volcano.

Sakurajima (Kyushu, Japan): The IAVECI 2013 conference over, activity has dropped a bit, it seems. The volcano still has a few vulcanian explosions per day, but smaller in size, and phases of near-continuous ash emissions have become a bit weaker and shorter when observed last night.

Lokon-Empung (North Sulawesi, Indonesia): An explosion occurred Monday (22 July) morning at 05:06 local time, producing an ash plume of about 1200 m height.

Popocatépetl (Central Mexico): Emissions have been up to 2 per hour on average, but remained very small. A volcano-tectonic magnitude 2.3 quake occurred at 00:47 (local time) yesterday.

Santa María / Santiaguito (Guatemala): The lava dome has been very calm during the past day. No explosions and no movement at the previously active lava flow (on the southern slope) were observed.

Pacaya (Guatemala): Seismic and surface activity have increased during the past days, characterized by the appearance of continuous tremor and more frequent strombolian explosions, the latest special bulletin of INSIVUMEH notes. This suggests a batch of fresh magma is currently rising. The Guatemalan scientists think that it is likely that strombolian activity will increase and perhaps a lava flow will appear on the flanks of the volcano in the coming days.

Fuego (Guatemala): Activity has remained low. INSIVUMEH reports only few and weak explosions (producing ash plumes up to 400 m height) and the active lava flow decreased to 50 m length.

Telica (Nicaragua): Seismic activity has decreased a bit, although small earthquakes are still frequent.

Galeras (Colombia): A magnitude 3.2 earthquake occurred under the volcano yesterday morning. The quake was felt by some nearby residents.

Reventador (Ecuador): Activity remains at high levels, characterized by small explosions and the likely effusion of lava flows. Unfortunately, near-constant cloud cover makes direct observations difficult.

Tungurahua (Ecuador): An increase in activity has occurred since yesterday. For 24 July, IGPEN reports an eruption column of steam and ash reaching 5 km above the crater drifting into westerly directions. During the past night, a further rise in activity has likely occurred, as the increasing tremor signal suggests.

Arctic Methane an 'Economic Time Bomb'.

Increasing temperatures in the Arctic region are reducing sea ice cover and increasing the possibility of methane leaching from the sea bed. Scientists say that the release of large amounts of methane from thawing permafrost in the Arctic could have huge economic impacts for the world.

68925800 82947407

The researchers estimate that the climate effects of the release of this gas could cost $60 trillion (£39 trillion), roughly the size of the global economy in 2012. The impacts are most likely to be felt in developing countries they say. Scientists have had concerns about the impact of rising temperatures on permafrost for many years. Large amounts of methane are concentrated in the frozen Arctic tundra but are also found as semi-solid gas hydrates under the sea. Previous work has shown that the diminishing ice cover in the East Siberian sea is allowing the waters to warm and the methane to leach out. Scientists have found plumes of the gas up to a kilometre in diameter rising from these waters.

Methane is a powerful greenhouse gas, even though it lasts less than a decade in the atmosphere. the researchers examined the impact of the release of 50-gigatonnes of methane over a decade. They worked out that this would increase climate impacts such as flooding, sea level rise, damage to agriculture and human health to the tune of $60 trillion. "That's an economic time bomb that at this stage has not been recognised on the world stage. We think its incredibly important for world leaders to really discuss what are the implications of this methane release and what could we indeed do about it to hopefully prevent the whole burst from happening."

The researchers say their study is in marked contrast to other, more upbeat assessments of the economic benefits of warming in the Arctic region. It is thought that up to 30% of the world's undiscovered gas and 13% of undiscovered oil lie in the waters. Transport companies are looking to send increasing numbers of ships through these fast melting seas. Investment in the Arctic could reach $100bn within ten years.

But according to the new work, these benefits would be a fraction of the likely costs of a large scale methane emission. The authors say a release of methane on this scale could bring forward the date when global temperatures increase by 2C by between 15 and 35 years. New research suggests that permafrost is also melting in Antarctica. Scientists have found that ground ice in the McMurdo Dry Valley Regions has accelerated consistently between 2001 and 2012, rising to about ten times the historical average. The researchers say that rising temperatures do not account for this increased melting but is due to an increase in sunlight caused by changes in weather patterns.

"We are looking at a big effect, a possibly catastrophic effect on global climate that's a consequence of this extremely fast sea ice retreat that's been happening in recent years." Some scientists have cautioned that not enough is known about the likelihood of such a rapid release of methane. Even though it has been detected for a number of years, it has as yet not been found in the atmosphere in large amounts. But the evidence is growing. "We are seeing increasing methane in the atmosphere. When you look at satellite imagery, for instance the Metop satellite, that's gone up significantly in the last three years and the place where the increase is happening most is over the Arctic."

The authors say that the impacts of the extra methane would be felt most in developing countries which are more vulnerable to rising waters, flooding and the agricultural and health impacts of rising temperatures.

Dead Eels in China

Tens of thousands of dead eels have washed ashore in China over the past few weeks.

The eel is just the latest animal to die en masse in China's waters. In March, thousands of dead pigs were dumped by farmers into the Hangpu River in Shanghai, and hundreds of dead ducks and fish have also turned up in Chinese waterways.

Although no one knows the cause yet, some suspect the China National Offshore Oil Company may be responsible. That company is doubling its crude oil production.

But the company and local administrators say the eels died of natural causes. The company says ocean currents brought a confluence of low temperatures, low oxygen and high salt content that killed off the eels.

Global Warming

North Pole Now a Lake

Instead of snow and ice whirling on the wind, a foot-deep aquamarine lake now sloshes around a webcam stationed at the North Pole. The meltwater lake started forming July 13, following two weeks of warm weather in the high Arctic. In early July, temperatures were 2 to 5 degrees Fahrenheit (1 to 3 degrees Celsius) higher than average over much of the Arctic Ocean, according to the National Snow & Ice Data Centre.

Meltwater ponds sprout more easily on young, thin ice, which now accounts for more than half of the Arctic's sea ice. The ponds link up across the smooth surface of the ice, creating a network that traps heat from the sun. Thick and wrinkly multi-year ice, which has survived more than one freeze-thaw season, is less likely sport a polka-dot network of ponds because of its rough, uneven surface.

July is the melting month in the Arctic, when sea ice shrinks fastest. An Arctic cyclone, which can rival a hurricane in strength, is forecast for this week, which will further fracture the ice and churn up warm ocean water, hastening the summer melt. The Arctic hit a record low summer ice melt last year on Sept. 16, 2012, the smallest recorded since satellites began tracking the Arctic ice in the 1970s.

Roundup of Global Volcanic Activity:

Tolbachik (Kamchatka): There are no signs of the eruption ending soon. Although an overall weakly decreasing trend is visible over the past months, tremor levels reported by KVERT remained stable during the past week and lava continues to be erupted form the southern fissure, feeding a vast flow field mainly SE of the volcano.

Sakurajima (Kyushu, Japan): Activity remains elevated. During most of the time, the volcano produces (usually silent) near-continuous ash puffs that reach varying heights of a few hundred meters, as well as intermittent vulcanian explosions with plume heights often exceeding 3 km. Often, the plumes from this activity merge into a continuous one that has been drifting into easterly directions where light to moderate ash fall occurs. The eastern sector of the volcano is covered by up to several cm of fresh ash from the activity during the recent weeks.

Merapi (Central Java): A small explosive eruption occurred from the volcano yesterday (22 July) morning between 04:22 and 05:35 local time. It produced a dark ash plume rising about 1000 m and ash fall in the villages of Klaten (SE of the volcano) and Sleman (SW).

White Island (New Zealand): The "drumbeat" earthquake activity, which could be caused by pulsating steam and gas emissions from a narrow conduit continues. Over the past days, the intensity of seismic activity has risen, but dropped again a bit at the moment.

Veniaminof (Alaska Peninsula, USA): AVO reports no changes in activity: continuous low-level volcanic tremor, elevated surface temperatures at the intracaldera cone, visible glow and low-level ash and steam plumes indicate that lava flows continue to be erupted, along with mild strombolian activity.

Popocatépetl (Central Mexico): Activity has been low during the past days. Emissions of steam, gas and only sometimes small amounts of ash occurred at rates fluctuating between 0-3 per hour and plumes reached a maximum of about 1 km above the crater.

Turrialba (Costa Rica): The seismic crisis continues with a swarm of volcanic-tectonic quakes as well as periods of low-frequency tremor and possible small explosion signals (which could suggest small phreatic eruptions). OVSICORI wrote that on 18 July, over 1000 earthquakes were recorded on a single day.

Reventador (Ecuador): Small to moderate explosions and (probably) the effusion of a lava flow on the NE side of the cone continue. Seismic activity is high.

Tungurahua (Ecuador): Activity remains high. The volcano produces intermittent explosions and near continuous strombolian explosions and ash emissions that produce an eruption column reaching up to 1.5 km above the crater. Easterly winds drift the ash mainly to the west and SE, where light ash fall occurred in Cahuají and Choglontus.

Last August a similar system developed in the area which destroyed 800,000 square km of ice. This system looks even stronger than last year's, and much of the ice in the area is thinner first year ice, so there could be drastic changes in the Arctic sea ice over the next week or so.

New Antarctic Evidence Reveals Past Melting

One of the wild cards in estimating future sea level rise from global warming is the enormous East Antarctic Ice Sheet, which holds more freshwater in its icy expanse than the whole of Greenland.

Some climate models predict the giant ice sheet will undergo relatively little change as the planet warms in coming decades, while others forecast significant melting. Now, a new study suggests parts of the East Antarctic Ice Sheet underwent significant melting during the Pliocene, a recent geologic epoch when climate conditions were similar to those of today.

Scientists previously considered the East Antarctic Ice Sheet to be more stable than the much smaller ice sheets in West Antarctica and Greenland, even though very few studies of the East Antarctic Ice Sheet have been carried out. New work now shows that the East Antarctic Ice Sheet has been much more sensitive to climate change in the past than previously realized.

During the Pliocene epoch between 5.3 million to 2.6 million years ago, geologic evidence indicates atmospheric levels of carbon dioxide were similar to modern levels of 400 parts per million (meaning that for every million air particles, 400 of them are carbon dioxide molecules) and global temperatures were 2 to 3 degrees Celsius (about 3.6 to 5.4 degrees Fahrenheit) higher than they are now. Sea levels stood about 66 feet (20 meters) higher, according to ancient preserved shorelines.

To raise sea level that much, all of Greenland and West Antarctica had to be ice-free and parts of East Antarctica may have melted, modeling studies show. (The Antarctic ice sheet first started forming 34 million years ago.)

Researchers looked for evidence of past ice melting by drilling into deep-sea sediments offshore of East Antarctica. The ancient mud contains a unique geochemical fingerprint that matches bedrock in the Wilkes Subglacial Basin, which is now thickly covered with ice. The sediments were deposited between about 5 million to 3 million years ago, indicating the ice sheet retreated several hundred kilometres (about 200 miles) inland, exposing the bedrock. Erosion carried the sediments offshore.

The findings were published July 21 in the journal Nature Geoscience.

Roundup of Global Volcanic Activity:

Kizimen (Kamchatka): A rock spine that had been growing at the summit of the active lava dome has collapsed, producing pyroclastic flows and an ash plume rising to 20,000 ft (6 km) altitude.

Shiveluch (Kamchatka): An explosion and/or partial dome collapse produced an ash plume rising to 15,000 ft (4.7 km) last night and drifting east (Tokyo VAAC).

Sakurajima (Kyushu, Japan): A strong vulcanian explosion occurred last night at 11:02 GMT (20:02 local time), following several hours of near complete calm at the volcano. A loud cannon-shot bang accompanied the explosion, which generated a large mushroom cloud that reached 12,000 ft (3.7 km) altitude and engulfed the NE half of the Sakurajima peninsula and was followed by several smaller ones within about half an hour. The volcano and much of the surrounding areas remained under the ash plume for several hours until it started to clear up again. In the hours after the explosion, the Showa crater continued to emit ash plumes in often near-continuous pulses, sometimes reaching several 100 m height, but with no visible incandescence or audible sounds.

Bagana (Bougainville Island, Papua New Guinea): An small SO2 plume is seen on satellite images drifting from Bagana volcano. This suggests continuing activity.

Merapi (Central Java): Merapi volcano, on the island if Java, Indonesia produced a moderate emission of ash earlier today. Locals reported an eruption of dark red material to a height of 1 km was reported. Rainfall that was occurring at the time, mixed with the ash to create a heavy mud that forced locals to evacuate the slopes of the volcano.

Popocatépetl (Central Mexico): The volcano has quieted down and produces only smaller emissions of mainly steam and gas at rates of 1-2 per hour.

Santa María / Santiaguito (Guatemala): Activity remains low with no significant changes. Few explosions occur, but the lava flow on the southern slope of the Caliente dome remains weakly active.

Pacaya (Guatemala): Activity has dropped at bit apparently. Although the seismic signal suggests that small strombolian-type explosions still seem to continue, INSIVUMEH reported only degassing and no sounds of explosions heard.

Fuego (Guatemala): There are no significant changes in activity, which remains weak (8 small to moderate explosions during 20-21 July) and mainly effusive; the lava flow on the southern side was about 300 m long and produced small avalanches of blocks towards the Taniluya canyon.

Tungurahua (Ecuador): An increase of activity occurred yesterday. IGPEN recorded 3 strong pulses of volcanic tremor since midnight 20-21 July (local time), which were accompanied by strombolian activity and strong explosions that produced loud roars, heavy gunfire sounds, and vibrations that rattled floors, windows and doors of houses in areas nearby. Some were heard even in the Tungurahua Volcano Observatory (OVT), located 14 km north of the volcano. The largest explosion yesterday at 14h18 (local time) generated an eruption column of 5 km height moving east.

Roundup of Global Volcanic Activity:

Sakurajima (Kyushu, Japan): The volcano continues to produce relatively frequent and strong ash-rich explosions, but activity has decreased a bit compared to previous days. During last night, it had long-lasting (up to 1-2 hours) phases of continuous ash emissions of various intensity, with dense plumes up to about 500 m height, but completely silent and with no visible incandescence. During other phases, it was emitting a small plume of vapour with some dilute ash. Explosions occurred at intervals of 1-10 hours, producing large ash plumes, but ejecting relatively few bombs. Small lightnings could be seen in the eruption plumes.

Reventador (Ecuador): Effusive and explosive activity at the surface as well as seismicity have continued to increase. A lava flow is traveling from the summit crater on the southern side towards the SE flank and there are numerous small explosions which create ash plumes of up to about 1 km height. In its latest special report, IGPEN summarizes the evolution since 12 July as follows:

Tungurahua (Ecuador): Activity both at the surface and internal remains at moderately high levels. Since the large vent-clearing vulcanian explosion on 14 July, the volcano has been producing strong strombolian activity and near-continuous ash emissions. This is accompanied by numerous long-period (LP) earthquakes and an elevated output of SO2 (3000 tonnes per day), as well as inflation at the northern flank in combination with weaker deflation of an area SW of the volcano (where the source of the magma might be located at about 2 km depth).

'Brown Ocean' Can Fuel Inland Tropical Cyclones

Before making landfall, tropical storms gather power from the warm waters of the ocean. When storms move over land, they normally lose power. A handful of tropical storms and hurricanes have defied the odds and strengthened over land. Now researchers believe they have a better understanding why this occurs.

Tropical systems are expected to weaken while interacting with land, but if conditions are ideal, a land mass can feed these entities and act as a "brown ocean." A recently released study, funded by NASA and conducted by Drs. Theresa Andersen and Marshall Shepherd of the University of Georgia has found that abundant soil moisture can continue to feed a tropical storm or hurricane long after it has left the warm waters of an ocean.

Pollution Shortens Life-Expectancy - China

Chinese living in heavily polluted northern areas of the country have their lives cut by an average of 5.5 years by airborne toxins compared to those living in the relatively cleaner south of the country.

A report published in the Proceedings of the National Academy of Sciences says that the widespread use of coal in the north is the main cause of the shorter life spans.

Using official data from Chinese sources, an American, an Israeli and two Chinese scholars found that decades of burning coal have led to more deaths from cardio-respiratory diseases for people living north of the Huai River, which is considered the dividing line between northern and southern China.

The use of coal in central heating systems in colder northern climes is the main reason for the high emissions.

Coal has also been used to feed the explosive growth of heavy industry there.

In the aftermath of China’s Maoist revolution, the government began giving free coal for boilers so people could keep warm during the north’s cold winters. That policy is still in place.

Fracking Appears to Cause Quakes - USA

The deep injection into the ground of wastewater byproducts from hydraulic fracturing, or fracking, has caused a significant increase in U.S. earthquakes since the practice has recently become more widespread.

The U.S. Geological Survey (USGS) reports that there were more than 300 earthquakes above magnitude 3.0 from 2010 to 2012, which is a five-fold increase from the average number of 21 tremors per year measured from 1967 to 2000.

There are now more than 30,000 deep disposal wells in the country, typically injecting leftover fluids from fracking wells used for natural gas extraction.

And while the actual practice of fracking has not been found to cause any significant seismic events, the far deeper injecting of wastewater from the practice has.

Sometimes the water is blasted into deep, dormant faults. USGS geologist William Ellsworth says that even faults that have not moved for millions of years can be made to slip if conditions are right.

But he points out that only a few of the approximately 30,000 wastewater wells appear to have caused the increase in tremors.

Columbia University scientists caution that powerful earthquakes thousands of miles away can trigger swarms of minor quakes near injection wells as the arriving seismic waves help release the local built-up pressure.

Russia Blocks Bid to Protect Antarctic Waters

Russia shot down a bid to create vast marine sanctuaries in Antarctica's waters, rousing dismay among environmental groups.

Delegations from 24 countries and the European Union met in Germany this week to decide whether to adopt two proposals to designate Marine Protected Areas (MPAs) around the frozen continent. But Russia, with some support from Ukraine, questioned the legal authority of the group to establish such reserves.

The MPAs would restrict fishing in certain areas and are designed to preserve habitats for iconic species, like whales and emperor penguins, and maintain sustainable stocks of commercially valuable fish in Antarctica's fragile waters. One proposed MPA, submitted by the United States and New Zealand, would cover 2.3 million square kilometres of the Ross Sea; the other, put forth by Australia, France and the European Union, would create a group of seven protected areas in East Antarctica.

Both proposals had been submitted last October at the annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). When member nations failed to reach a consensus then, they called for this week's special meeting in Germany. The delegates will take up the issue again at the next annual meeting, in Hobart, Tasmania.

Roundup of Global Volcanic Activity:

Churchill (United States, Eastern Alaska): A seismic swarm with magnitudes up to 3.5 has been occurring in the Wrangell Arc about 40 km NE of Mt. Churchill volcano during the past few days. The intensity and frequency of the quakes has calmed down yesterday. While some few of the quakes are near the volcano, most are not, and the swarm is probably not linked to the volcanic system of Mt Churchill volcano.

Long Valley (California): Normal seismic activity with numerous tiny earthquakes continues to occur at the southern and western parts of the caldera as well as under Mammoth mountain. There are no signs of a possible eruption in a near future.

Colima (Western Mexico): Although the volcano is no longer making much news, a lava flow continues to effuse as a viscous flow on the upper eastern flank of the volcano.

Popocatépetl (Central Mexico): Activity has been comparably low with an average of 1-2 emissions of steam and gas, sometimes some ash, per hour during the past days. The strong explosion from 12 July has effectively destroyed the new lava dome, an aerial inspection via helicopter on 15 July showed. In the past 24 hours, a number of volcanic-tectonic quakes have appeared, which could indicate that a new batch of magma is currently intruding, and lead to another phase of increased activity soon. The alert level remains unchanged at Yellow Phase 3.

Santa María / Santiaguito (Guatemala): Not much has changed in the generally weak activity. Occasional explosions, sometimes moderately large, occur at irregular intervals. One yesterday morning at 05:59 local time produced an ash plume of 700 m height and ash fall in areas to the SW. The lava flow on the southern flank of the dome remains active and produces small rock avalanches.

Pacaya (Guatemala): Mild strombolian activity from the Mackenney crater continues.

Fuego (Guatemala): The lava flow on the southern side has remained active and was about 250 m long this morning, producing near-constant rockfalls towards the Taniluya canyon. At the summit, there are occasional strombolian explosions with incandescent material ejected to 100-125 m height above the crater.

Telica (Nicaragua): The swarm of small earthquakes continues with little changes over the past days.

San Cristobal (Nicaragua): Some elevated seismicity was recorded at the volcano during recent days and continues. This includes phases of harmonic tremor and long-period events.

Turrialba (Costa Rica): The seismic swarm continues but has decreased in strength during the past day.

Tungurahua (Ecuador): After the strong vulcanian explosion on 14 July, the volcano calmed down first, but resumed activity on 16 July which has been characterized by ash venting and small to moderate explosions and is continuing. This activity was accompanied by the appearance of tremor and long-period earthquakes indicative of fluid movements. In addition, inflation is measured at the NW flank, suggesting that more magma is rising, and could lead to new powerful explosions similar to the one from last Sunday.

Sabancaya (Peru): A strong seismic swarm has occurred during the past days under the volcano, culminating in a magnitude 5.9 earthquake on 16 July. The swarm consisted almost entirely of volcanic-tectonic quakes, that relate to rock fracturing due to rapid pressure changes and might be caused by an intrusion of magma. IGP reports that up to 1500 earthquakes were recorded per day. At the moment, the swarm still continues, but is decreasing. No changes of activity have been noticed at the surface. The number of long-period quakes (thought to correspond to internal movements of magma, gasses and other fluids) has remained low.

Heatwave in England

Health warnings have been issued as heatwave conditions are reached in London and the South East. The Met Office issued a "Level 3" warning on the hottest day of the year, with temperatures hitting 32C (89.6F) at Northolt, west London. Level 3 is one notch below the most serious warning in the Met Office's heat-health watch system. The warning alerts healthcare services to help those in high-risk groups such as the elderly and young children.

Two similar heatwave warnings were issued last week in Yorkshire and the Humber, and in south-west England after road surfaces melted and tracks buckled in the heat.

Doctors in Wales say the number of people suffering sunstroke, sunburn and heatwave-related injuries is stretching hospital emergency departments. In north-east England it was 28C, in Wales 30C and in London 32C. The night-time trigger temperatures vary from 15C to 18C.

California

The fast-growing wildfire in the mountains of Southern California forced the evacuation on Wednesday of the popular resort community of Idyllwild after flames engulfed seven homes and numerous other buildings.

By late Wednesday, the fire had charred more than 19,000 acres (7,700 hectares) of drought-parched chaparral and timber, much of it in steep, remote wilderness terrain inside the San Bernardino National Forest. That was more than double the acreage reported burned a day earlier by the so-called Mountain Fire.

With nearly 3,000 firefighters, 17 water-dropping helicopters and 10 air tankers assigned to it, the blaze ranked as one of the most severe of some 16 large, wildfires that crews were battling to contain in several western states. As of Wednesday evening, firefighters had managed to carve containment lines around 15 percent of its perimeter.

Roughly 100 homes in a handful of small communities near Idyllwild and Palm Springs were ordered evacuated during the first two days of the blaze and early on Wednesday. Evacuation orders were expanded Wednesday evening to Idyllwild itself, along with part of the adjacent, smaller community of Fern Valley and all parks and campgrounds in the vicinity.

No injuries have been reported, but authorities say seven residences, including three mobile homes, have been destroyed, along with one commercial structure, more than a dozen outbuildings and several vehicles.

Nyamuragira volcano (DRCongo) activity update: steaming/degassing from pit inside summit caldera. Recent NASA satellite images from 11 June 2013 show a thick steam and gas plume rising from a pit crater in the summit caldera of Nyamuragira volcano. No evidence of lava close to the surface was found, while the lava lake in neighboring Nyiragongo remains well active and visible on the same images. Nyamuragira's plume was rich in water vapor — which condenses rapidly in the humid tropical air — and sulfur dioxide, which lends a blue tint in natural-color satellite imagery. Carbon dioxide, fluorine, and chlorine gas are also found in Nyamuragira lavas and likely present in the gas plume. Located near the eastern boundary of the Democratic Republic of the Congo, Nyamuragira is one of Africa’s most active volcanoes. If degassing magma was near the surface, then the intense heat would cause a bright red glow in shortwave infrared light. No such glow is visible atop Nyamuragira, but it is present on neighboring Nyiragongo Volcano, which has featured a lava lake for more than a decade.

A wildfire in mountains west of Palm Springs burned seven homes and led to the evacuation of dozens more. Several vehicles were also burned.

The wildfire started Monday between Palm Springs and Hemet, near the rural Riverside County community of Mountain Centre, and a day later had surged to about 14 square miles.

More than 2,200 firefighters and 25 aircraft had the blaze 10 percent contained.

It was mostly moving east toward the desert and away from small communities of homes, summer cabins and ranches in the San Jacinto mountains. But a shift in the wind could easily sweep it back toward homes.

Fire crews are working to contain a wildfires near Lyle and Okanogan, Washington.

The B & O Fire, which is being pushed by gusty winds in north-central Washington., has burned across more than 3 square miles, or about 2,000 acres, between Okanogan and Malott, south of Omak.

The fire has closed some roads, including a 2-mile stretch of Highway 20 and B&O Road to the Methow Valley.

An official with the Okanogan County Emergency Management department says nearly 5,000 customers are without power because of burnt power lines. It is expected residents and business owners could be without power for more than 24 hours.

The Washington state Department of Natural Resources says two helicopters are dropping water on the fire, along with a single-engine air tanker. The cause of the fire is under investigation.

Meanwhile Washington DNR says that one home was lost and a crew of 70 are working to contain an approximately 100 acre fire. The fire is currently 60 percent contained and was likely started by humans.

CDC Travel Warnings

People planning to travel domestically or abroad are advised to take precautions against insect-borne and viral diseases after several cases of scrub typhus were reported in Taiwan, while Southeast Asia, Europe and England are experiencing outbreaks of dengue fever and measles, mumps, and rubella (MMR) respectively, the Centres for Disease Control (CDC) said yesterday.

The CDC said that as of Monday, there have been 147 confirmed cases of scrub typhus in Taiwan this year, one of which was fatal. Scrub typhus is endemic to tropical and subtropical regions and is transmitted through the bite of chiggers — scrub mite larvae — carrying the Orientia tsutsugamushi parasite.

The CDC added that while the mortality rate of the diseases is less than 5 percent if treated promptly, the probability can go up to 60 percent if the infected person fails to seek medical assistance.

For travellers going to Southeast Asia, the CDC warned them to be aware of the serious outbreak of mosquito-borne dengue fever currently afflicting the region. It said that the epidemic this year is so far proving to be a lot worse than those seen in the previous years.

The CDC also urged caution for those visiting Europe as the region is experiencing a rubella outbreak exacerbated by low vaccine coverage and England is suffering the largest measles outbreak of the past decade.
