Scientists followed the journey of water through the Tarim Basin from the rivers at the edge of the valley to the desert aquifers under the basin. They found that as water moved through irrigated fields, the water gathered dissolved carbon and moved it deep underground.

‘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.…

The Lewis and Crok exposition – Climate less sensitive to Carbon Dioxide than most models suggest

Full papers plus additional comments from co-author Nic Lewis follow. I have added some relevant diagrams and tables from the report, plus reproduced the foreword by Dr. Judith Curry as well as updated the summary Equilibrium Climate Response Graph originally by Dr. Patrick Michaels to include this new ECS value and range. – Anthony NEW…

CO2 Residence Times, Take Two

Guest essay by Joe Born In a recent post Christopher Monckton identified me as a proponent of the following proposition: The observed decay of bomb-generated atmospheric-carbon-14 concentration does not tell us how fast elevated atmospheric carbon-dioxide levels would subside if we discontinued the elevated emissions that are causing them. He was entirely justified in doing…

Is the Bern Model Non-Physical?

Guest essay by Joe Born Is the Bern Model non-physical? Maybe, but not because it requires the atmosphere to partition its carbon content non-physically. A Bern Model for the response of atmospheric carbon dioxide concentration to anthropogenic emissions is arrived at by adopting the values of , (and maybe ) that make the best fit…
