Rapid climate change and the role of the Southern Ocean
Scientists from Cardiff University and the University of Barcelona have discovered new clues about past rapid climate change.
New study reconciles carbon record disparities on land and on sea
(Phys.org) —It's a pressing question: How will the Earth's climate respond to future increases in atmospheric carbon dioxide (CO2)? Throughout geologic history, evidence of rapid, large-scale increases ...
Soils in newly forested areas store substantial carbon that could help offset climate change
Surface appearances can be so misleading: In most forests, the amount of carbon held in soils is substantially greater than the amount contained in the trees themselves.
Elevated carbon dioxide in atmosphere trims wheat, sorghum moisture needs
Plenty has been written about concerns over elevated levels of carbon dioxide in the earth's atmosphere, but a Kansas State University researcher has found an upside to the higher CO2 levels. And it's been particularly relevant ...
Dead forests release less carbon into atmosphere than expected
(Phys.org) —Billions of trees killed in the wake of mountain pine beetle infestations, ranging from Mexico to Alaska, have not resulted in a large spike in carbon dioxide released into the atmosphere, contrary ...
Blue mussels 'hang on' along rocky shores: For how long?
Imagine trying to pitch a tent in a stiff wind. You just have it secured, when a gale lifts the tent—stakes and all—and carries it away.
Breaking down the bubbly: Micromodels redefine how bubbles characterize CO2 gas flow
One of the most noteworthy concerns for the U.S. Department of Energy is controlling atmospheric carbon dioxide to mitigate its effects on global climate and, in turn, energy consumption. Geological formations, ...
Salt marsh restoration could bring carbon benefits
Allowing farmland that's been reclaimed from the sea to flood and turn back into salt marsh could make it absorb lots of carbon from the atmosphere, a new study suggests, though the transformation will take ...
Large solar proton event explains 774-775 CE carbon-14 increase
Tree ring records indicate that in 774-775 CE, atmospheric carbon-14 levels increased substantially. Researchers suggest that a solar proton event may have been the cause. In solar proton events, large numbers of high-energy ...
Bugs in the atmosphere: Study finds substantial microorganism populations in troposphere
(Phys.org)—In what is believed to be the first study of its kind, researchers used genomic techniques to document the presence of significant numbers of living microorganisms – principally bacteria – ...
In prehistory, CO2 and warming went in lock-step
Levels of carbon dioxide rose hand-in-hand with warming at the end of the last Ice Age, according to a study Thursday that deals a blow to climate skeptics.
Researchers find new information about 'Snowball Earth' period
It is rather difficult to imagine, but approximately 635 million years ago, ice may have covered a vast portion of our planet in an event called "Snowball Earth." According to the Snowball Earth hypothesis, the massive ice ...
Global warming: Heat stress hits labour productivity
Heat stress from global warming may be having an impact on outdoor work productivity in hot regions like northern Australia, Southeast Asia and the southern United States, a study said Sunday.
Forecast is for more snow in polar regions, less for the rest of us
A new climate model predicts an increase in snowfall for the Earth's polar regions and highest altitudes, but an overall drop in snowfall for the globe, as carbon dioxide levels rise over the next century.
