Climate Change Can Cause Loss of Important Ice Dynamics in Streams
Feb. 16, 2015 Ice and winter floods are important natural disturbances for maintaining species-rich riparian zones along northern watercourses. If the climate becomes warmer this disturbance might be lost. This ... full story -
Carbon Release from Ocean Helped End the Ice Age
Feb. 11, 2015 A release of carbon dioxide from the deep ocean helped bring an end to the last Ice Age, according to new research. The study shows that carbon stored in an isolated reservoir deep in the Southern ... full story -
Global Sea Ice Diminishing, Despite Antarctic Gains
Feb. 10, 2015 Sea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades, a new study finds. As a whole, the planet has been shedding sea ice at an average annual ... full story -
