NASA study shows 13-year record of drying Amazon caused vegetation declines
A 13-year decline in vegetation in the eastern and southeastern Amazon has been linked to a decade-long rainfall decline in the region, a new NASA-funded study finds.
Europe now ten times likelier to get heatwaves, study finds
Scientists who a decade ago found that global warming had doubled the risk of an extremely hot summer in Europe reported on Monday that such an event was now 10 times likelier.
Climate change challenge for animals reliant on external sources of heat
Animals that regulate their body temperature through the external environment may be resilient to some climate change but not keep pace with rapid change, leading to potentially disastrous outcomes for biodiversity.
Commentary calls for new 'science of climate diversity'
There is cloud hanging over climate science, but one Cornell University expert on communication and environmental issues says he knows how to help clear the air.
How strong is the gravity on Mars?
The planet Mars shares numerous characteristics with our own. Both planets have roughly the same amount of land surface area, sustained polar caps, and both have a similar tilt in their rotational axes, affording ...
The yin-yang of polar sea ice
It comes as no surprise, therefore, when researchers announce as they did this past September that Arctic sea ice extent is still below normal, continuing a years-long downward trend, covering less and less ...
What would happen to the climate if we stopped emitting greenhouse gases today?
Earth's climate is changing rapidly. We know this from billions of observations, documented in thousands of journal papers and texts and summarized every few years by the United Nations' Intergovernmental Panel on Climate Change. The primary cause of that change is the release of carbon d ...

March of the penguin genomes
Two penguin genomes have been sequenced and analyzed for the first time in the open access, open data journal GigaScience. Timely for the holiday season, the study reveals insights into how these birds have b ...
Environmental 'tipping points' key to predicting extinctions
Researchers from North Carolina State University have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population's ...
Localized climate change contributed to ancient southwest depopulation
Washington State University researchers have detailed the role of localized climate change in one of the great mysteries of North American archaeology: the depopulation of southwest Colorado by ancestral ...
Fingers pointed as climate talks deadlock
