Asian monsoon much older than previously thought
The Asian monsoon already existed 40 million years ago during a period of high atmospheric carbon dioxide and warmer temperatures, reports an international research team led by a University of Arizona geoscientist.
Warming climates intensify greenhouse gas given out by oceans
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fuelling further climate change, a study suggests.
Researchers estimate amount of CO2 released into atmosphere by rivers and streams
Computer simulations indicate calcium carbonate has a dense liquid phase (w/ Video)
Computer simulations conducted at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) could help scientists make sense of a recently observed and puzzling wrinkle in one of ...
Sea urchins cope with rising CO2 levels
Plants Save the Earth from an Icy Doom (w/ Podcast)
(PhysOrg.com) -- Fifty million years ago, the North and South Poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. ...
Past climate change and continental ice melt linked to varying CO2 levels
Scientists at the Universities of Southampton and Cardiff have discovered that a globally warm period in Earth's geological past featured highly variable levels of CO2.
Research resolves discrepancy in Greenland temperatures during end of last ice age
A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming occurred.
How Earth avoided global warming, last time around
Geochemists have calculated a huge rise in atmospheric CO2 was only avoided by the formation of a vast mountain range in the middle of the ancient supercontinent, Pangea. This work is being presented to the ...
Researchers look to the Southern Ocean for an explanation of the 'Last Glacial Maximum'
The paleoclimate record for the last ice age—a time 21,000 years ago called the "Last Glacial Maximum" (LGM)—tells of a cold Earth whose northern continents were covered by vast ice sheets. Chemical traces ...
Transforming hydrogen into liquid fuel using atmospheric CO2
Swiss scientists have completed their solution for transforming hydrogen gas into a less flammable liquid fuel that can be safely stored and transported. Another possible application of their technology would ...
Ancient forests stabilized Earth's CO2 and climate
UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low fo ...
'Global sunscreen' plan could wreck tropics, study finds
An idea by the father of the H-bomb to slow global warming by sowing the stratosphere with light-reflecting particles could wreck the weather system in the tropics, a study said Wednesday.
Four degree rise will end vegetation 'carbon sink'
Latest climate and biosphere modelling suggests that the length of time carbon remains in vegetation during the global carbon cycle - known as 'residence time' - is the key "uncertainty" in predicting how Earth's terrestrial ...
