Shifting winds, ocean currents doubled endangered Galápagos penguin population

Aug. 6, 2015

Shifts in trade winds and ocean currents powered a resurgence of endangered Galápagos penguins over the past 30 years, according to a new study. These changes enlarged a cold pool of water the penguins rely on for food and breeding – an expansion that could continue as the climate changes over the coming decades, the study’s authors said.

Erratic as normal: Arctic sea ice loss expected to be bumpy in the short term

Feb. 4, 2015

“Human-caused global warming is melting Arctic sea ice over the long term, but the Arctic is a variable place, said Jennifer Kay, a fellow of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder and co-author of the new analysis out today in Nature Climate Change. - See more at:
