Well here in 'Merica we are in the midst of the great presidential race of Mitt vs Obama 2012, which of course will decide the fate of this country and therefore the world at large. Once again the country is divided on numerous issues; genital politics- who gets to marry who and what women can do with their fetuses; the role of big government vs small government; and how to recapture a robust middle class. However it has not escaped the notice of some that the issue of climate warming or "climate weirding" (which I prefer) has elicited nary a mention from either side. Perhaps both sides have been advised to not mention such a pressing issue- to either outright deny its existence or promise to curb it may be akin to political suicide at this pass. Even the Obama advisors who helped catapult Obama into presidency in '08 largely on a platform of green job growth may now realize all to well that any remedy we can muster to soothe our climate gods is akin to putting a bandaid on an amputated leg. It's too late.

This is for shame because if North America continues with drought conditions it will not be long some think before this country starts to see the food shortages and hence food riots that other countries are already experiencing. And when people are rioting on the streets for food or water the issues of who gets to marry who and even who gets to hire who will fall by the wayside. We will all be too hungry to really care.

Of course I could be wrong, we can all hope. But climate change, often dramatic, in the context of geological time is the rule rather than the exception.
A new paper written by William W. Hay and Sascha Floegel, New thoughts about the cretaceous climates and oceans, synthesizes much of the current thought regarding this critical juncture in earth's history.
Several new discoveries suggest that the climate of the Cretaceous may have been more different from that of today than has been previously supposed. Detailed maps of climate sensitive fossils and sediments compiled by Nicolai Chumakov and his colleagues in Russia indicate widespread aridity in the equatorial region during the Early Cretaceous. The very warm ocean temperatures postulated for the Mid-Cretaceous by some authors would likely have resulted in unacceptable heat stress for land plants at those latitudes, however, and may be flawed.
