‘Carbon sink’ detected underneath world’s deserts

WASHINGTON, D.C. – The world’s deserts may be storing some of the climate-changing carbon dioxide emitted by human activities, a new study suggests. Massive aquifers underneath deserts could hold more carbon than all the plants on land, according to the new research. Humans add carbon dioxide to the atmosphere through fossil fuel combustion and deforestation.…

Apparently, 4 degrees spells climate doom

One has to wonder though, since CO2 residence time has been said to be anywhere from  five year to hundreds, or even thousands of years, with no solid agreement yet, how they can be so sure of themselves? From the University of Cambridge 4 degree rise will end vegetation ‘carbon sink’ Latest climate and biosphere…

Negative feedback? Storing CO2 in the Arctic

From the Massachusetts Institute of Technology: While the Arctic Ocean is largely a carbon sink, researchers find parts are also a source of atmospheric carbon dioxide For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent…
