Just how powerful is the current El Niño? There’s more to the story than the very warm equatorial Pacific.
“Arctic amplification” of climate change remained in full swing in 2015, according to the 2015 Arctic Report Card. Broad areas of the Arctic were more than 5°F (3°C) warmer than average during the report card’s monitoring year (October 2014-September 2015).
Increasing air and sea surface temperatures, decreasing sea ice extent and Greenland ice sheet mass, and changing behavior of fish and walrus are among key observations released today in the Arctic Report Card 2015.
Few places on Earth are more strongly affected by El Niño than the Galápagos Islands, which straddle the equator in the eastern tropical Pacific. Guest blogger Kris Karnauskas explains why these unique islands are so biologically productive—and what happens to that productivity during El Niño.
