Black Carbon Soil Study: Global Warming Predictions Overstimated?

Global warming predictions are overestimated,
suggests study on black carbon
By Krishna Ramanujan

A detailed analysis of black carbon–the residue of burned organic
matter–in computer climate models suggests that those models may
be overestimating global warming predictions.

A new Cornell study, published online in Nature Geosciences,
quantified the amount of black carbon in Australian soils and found
that there was far more than expected, said Johannes Lehmann, the
paper’s lead author and a Cornell professor of biogeochemistry. The
survey was the largest of black carbon ever published.

Water Vapor Confirmed a Major Greenhouse Gas

Water vapor is one of the most powerful greenhouse gases. As the
oceans warm, thanks to rising levels of CO2, they evaporate water
vapor more freely into the atmosphere. Similarly, as the land surface
warms, it too evaporates more water vapor into the warming atmosphere.

As the atmosphere warms, thanks to rising levels of CO2, it can hold
more water vapor.

capable of doubling the warming due to carbon dioxide alone.”

Water vapor confirmed as major player in climate change

Water vapor is known to be Earth’s most abundant greenhouse gas, but
the extent of its contribution to global warming has been debated.
Using recent NASA satellite data, researchers have estimated more
precisely than ever the heat-trapping effect of water in the air,
validating the role of the gas as a critical component of climate
change.

Gift to Oil Industry Rushed Into Federal Register Before Bush Leaves Office
Final Oil Shale Regulations Endanger Lands, Communities of Colorado, Utah and Wyoming

WASHINGTON – November 17 – Ignoring the wishes of two governors and numerous members of Congress, the Bush administration announced today final regulations for a commercial oil shale program affecting almost 2 million acres of public lands in Colorado, Utah and Wyoming. These regulations lay out the rules governing royalty rates, evaluation of lease bids, mitigation requirements, and other technical and procedural elements of commercial oil shale leasing and production.
