New Temporary Island
Japan’s Coast Guard found a newly formed island about 750 miles south of Tokyo when a surveillance flight spotted an active eruption in a remote area south of Iwo Jima. The Japan Meteorological Agency says previous eruptions created islands in 1904, 1914 and 1986, with all eventually being eroded by waves and currents.
La Niña Return?
A La Niña watch has been issued for the tropical Pacific as the ocean-cooling phenomenon now has a 70% chance of developing from November to January. The sea surface between South America and Indonesia is now in a “neutral” phase between El Niño warming and La Niña.
La Niña typically pushes the polar jet stream northward, bringing wetter weather to the Pacific Northwest, western Canada and the Ohio Valley. But it may also bring ongoing dry conditions to California and the Desert Southwest, worsening droughts and wildfire threats. La Niña’s cooling can also contribute to an extended and active hurricane season.
