Emaciated Polar Bear - Reality of Global Warming

Wildlife photographer Kerstin Langenberger captured this shocking photo of a deathly thin and starving polar bear as it struggles to capture food in the melting icecaps. It shows the effects of climate change better than any explanation . . .

Global warming alert as El Niño returns with a vengeance

The world is starting to heat up again, say British scientists, raising speculation that a 15-year slowdown in the rate of global warming could be coming to an end.

A pause in the rate of global temperature rises since the late 1990s has baffled climate scientists and led some to question whether man-made climate change was a serious problem.

But last year was the warmest on record, according to the UN’s World Meteorological Organisation, and scientists at the UK’s Met Office say both this year and 2016 are shaping up to be just as hot.

The strengthening Pacific weather pattern, El Niño, which some US scientists forecast could be the most powerful in years, is likely to be one reason for the rise in temperatures.

California's 'Snow Drought'

In April, statewide measurements of water contents of California’s snowpack -- a major source of water for reservoirs during the summers -- showed that the water content in the snow was only 5 percent of the normal for that date, making it the lowest in a 75-year record. Further analysis of available data has now shown that the situation is much worse than previously estimated.

According to a new study, published Monday in the journal Nature Climate Change, the amount of snow in the Sierra Nevada is now at its lowest level in over 500 years.
