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.
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.
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
Global warming caused by chlorofluorocarbons, not carbon dioxide, new study says
Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal of Modern Ph ...
'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.
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 ...
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 ...
Late Cretaceous Period was likely ice-free
For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University ...
Major cuts to surging CO2 emissions are needed now, not down the road, study finds
In 2004 a very popular study aimed to address climate change by deploying wedges of different existing energy technologies or approaches. According to the study by Robert Socolow and Stephen Pacala, each wedge would avoid ...
Ocean acidification killing oysters by inhibiting shell formation, study finds
(Phys.org) —For the past several years, the Pacific Northwest oyster industry has struggled with significant losses due to ocean acidification as oyster larvae encountered mortality rates sufficient to ...
Scientists' role in swaying public opinion studied
(Phys.org)—Whatever their political persuasion, people are more likely to believe that global warming is caused by humans if they find out that most climate change scientists believe this is the case.
New study documents the natural relationship between CO2 concentrations and sea level
By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations ...
