Ice cores store atmospheric bubbles from a million years ago
Direct evidence for a positive feedback in climate change
A new study has confirmed the existence of a positive feedback operating in climate change whereby warming itself may amplify a rise in greenhouse gases resulting in additional warming.
Speed with which temperatures change will continue to increase over next several decades, study shows
An analysis of changes to the climate that occur over several decades suggests that these changes are happening faster than historical levels and are starting to speed up. The Earth is now entering a period ...
Australia drying caused by greenhouse gases and ozone
NOAA scientists have developed a new high-resolution climate model that shows southwestern Australia's long-term decline in fall and winter rainfall is caused by increases in manmade greenhouse gas emissions ...
New materials for capturing carbon dioxide from combustion gases
(Phys.org) —Carbon dioxide is both a culprit in global warming and also responsible for keeping the Earth warm enough to support life as we know it. It is odorless and colorless, often represented by a ...
An inside look at metal-organic framework in action
(Phys.org) —A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for ...
How do you feed 9 billion people?
An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.
Researchers clarify impact of permafrost thaw
As the Earth's climate continues to warm, researchers are working to understand how human-driven emissions of carbon dioxide will affect the release of naturally occurring greenhouse gases from arctic permafrost. ...
Unexplained gap in global emissions of potent greenhouse gases resolved
Reported emissions of a group of potent greenhouse gases from developed countries are shown to be largely accurate, but for the wrong reasons, according to new findings from an international team, led by ...
Study blames global warming for 75 percent of very hot days
If you find yourself sweating out a day that is monstrously hot, chances are you can blame humanity. A new report links three out of four such days to man's effects on climate.
Researchers predict gradual, prolonged release of greenhouse gases from thawing permafrost
There's qualified good news about one contributor to climate change, say researchers who have crunched data from a series of recent studies.
Warming temperatures implicated in recent California droughts
California has experienced more frequent drought years in the last two decades than it has in the past several centuries. That observed uptick is primarily the result of rising temperatures in the region, ...
Refined method to convert lignin to nylon precursor
A new study from the Energy Department's National Renewable Energy Laboratory (NREL) demonstrates the conversion of lignin-derived compounds to adipic acid, an important industrial dicarboxylic acid produced for its use as ...
Coral reveals long-term link between Pacific winds, global climate
New research indicates that shifts in Pacific trade winds played a key role in twentieth century climate variation, a sign that they may again be influencing global temperatures.
