What the ancient CO2 record may mean for future climate change
12 hours ago
The last time Earth experienced both ice sheets and carbon dioxide levels within the range predicted for this century was a period of major sea level rise, melting ice sheets and upheaval of tropical forests.
'Time machine' study warns of long-term dangers of ocean acidification
Oct 12, 2016
New research into the effects of ocean acidification suggests that, while marine organisms may be able to cope with the effects of climate change in the short term, the biological cost of doing so may be too high to guarantee ...
Biologist comments on a startling new finding in climate change research
Sep 30, 2016
The steady march of global warming over the past century has led to the thawing of permafrost—a layer of subsurface soil in the Arctic that usually remains frozen year-round. While that's troubling for local ecosystems, ...
Ancient global cooling gave rise to modern ecosystems
Sep 27, 2016
Around 7 million years ago, landscapes and ecosystems across the world began changing dramatically. Subtropical regions dried out and the Sahara Desert formed in Africa. Rain forests receded and were replaced by the vast ...
Soil will absorb less atmospheric carbon than expected this century
Sep 22, 2016
By adding highly accurate radiocarbon dating of soil to standard Earth system models, environmental scientists from the University of California, Irvine and other institutions have learned a dirty little secret: The ground ...
Greenhouse gas-monitoring aircraft keep tabs on the Amazon's rising methane levels
Sep 14, 2016
Research led by the National Centre of Earth Observation at the University of Leicester is going to new heights in the atmosphere to get a better handle on methane emitted from wetlands in the Amazon.
Westerly winds have blown across central Asia for at least 42 million years
Sep 13, 2016
The gusting westerly winds that dominate the climate in central Asia, setting the pattern of dryness and location of central Asian deserts, have blown mostly unchanged for 42 million years.A University of Washington geologist ...
Calculating the role of lakes in global warming
Sep 07, 2016
As global temperatures rise, how will lake ecosystems respond? As they warm, will lakes—which make up only 3 percent of the landscape, but bury more carbon than the world's oceans combined—release more of the greenhouse ...
Study finds increased ocean acidification due to human activities
Sep 07, 2016
Oceanographers from MIT and Woods Hole Oceanographic Institution report that the northeast Pacific Ocean has absorbed an increasing amount of anthropogenic carbon dioxide over the last decade, at a rate that mirrors the increase ...
Warmer, wetter climate would impair California grasslands, 17-year experiment finds
Sep 05, 2016
Results from one of the longest-running and most extensive experiments to examine how climate change will affect agricultural productivity show that California grasslands will become less productive if the temperature or ...
