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. ...
Increased atmospheric carbon dioxide makes trees use water more efficiently
The increase in atmospheric CO2 concentration has allowed trees across Europe to use their available water resources more efficiently, new research has shown.
Rising carbon dioxide levels stunt sea shell growth
Scientists have discovered that stunted growth can be a genetic response to ocean acidification, enabling some sea creatures to survive high carbon dioxide levels, both in the future and during past mass ...
First direct observation of carbon dioxide's increasing greenhouse effect
Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time. The researchers, led by scientists from the US Department of Energy's Lawrence Berkeley ...
Going negative: Removing carbon dioxide from the atmosphere
To combat climate change, President Obama has called for an 80 percent reduction in carbon dioxide (CO2) emissions by 2050. To help achieve this goal, the President has encouraged big investments in wind, ...
Carbon release from ocean helped end the Ice Age
A release of carbon dioxide from the deep ocean helped bring an end to the last Ice Age, according to new research led by the University of Southampton.
Evidence from warm past confirms recent IPCC estimates of climate sensitivity
New evidence showing the level of atmospheric CO2 millions of years ago supports recent climate change predications from the Intergovernmental Panel on Climate Change (IPCC).
Crops help to drive greater seasonal change in CO2 cycle
Each year in the Northern Hemisphere, levels of atmospheric carbon dioxide (CO2) drop in the summer as plants inhale, and then climb again as they exhale and decompose after their growing season. Over the ...
Researchers calculate 'hidden' emissions in traded meat
An international team of researchers has, for the first time, estimated the amount of methane (CH4) and nitrous oxide (N2O) that countries release into the atmosphere when producing meat from livestock, ...
