The Lavoisier Group - of scientists and climate experts with important things to say.
Greenie Watch - an outspoken and humourous critic of the GW "consensus"
One of the great things about Australians is that they don’t mince their words, so Greenie Watch calls James Hansen “warmist crook.”
The Lavoisier Group has a series of scientific papers and presentations that are understandable to those with a modicum of science education (sadly, that rules out 99% of British environmentalists) and Greenie Watch collects fascinating tidbits from all over the news and web and analyses them in typically forthright language.
Today, why not read a short slide presentation from the Lavoisier Group on why the Earth’s rotation, not around the Sun but around the centre of mass (CM) of the solar system (which are not absolutely the same thing) has not been taken into account in climate models but has serious impact on our temperature.

An example of the content of Greenie Watch:
MELTING GREENLAND?
The New York Times article below is so wrong on so many counts that it is difficult to know where to start in deconstructing it. It has basically swallowed Al Gore's poop whole and yet shows no sign of indigestion. At this stage I just append a few desultory comments at the foot of the article.
Greenland's ice sheet represents one of global warming's most disturbing threats. The vast expanses of glaciers - massed, on average, 1.6 miles deep - contain enough water to raise sea levels worldwide by 23 feet. Should they melt or otherwise slip into the ocean, they would flood coastal capitals, submerge tropical islands and generally redraw the world's atlases. The infusion of fresh water could slow or shut down the ocean's currents, plunging Europe into bitter winter.
The island's ice cover has already begun to disappear. "Changes in the ocean eat the ice sheet from underneath," says Sarah Das, a glaciologist at the Woods Hole Oceanographic Institution in Massachusetts. "Warmer water causes the glaciers to calve and melt back more quickly." Hunters who use the frozen surface of the winter ocean for hunting and travel have found themselves idle when the ice fails to form. The whales, seals and birds they hunt have begun to shift their migratory patterns. "The traditional culture will be hard hit," says Jesper Madsen, director of the department of Arctic environment at the University of Aarhus in Denmark. "But from an overall perspective, it will have a positive effect." Greenland's fishermen are applauding the return of warm-water cod. Shops in the island's capital have suddenly begun to offer locally produced potatoes and broccoli - crops unimaginable a few years earlier.
The claims above show that the author needs to learn some history, climatology, geology, glaciology and oceanography. No such problems happened 1,000 years ago when the Vikings farmed coastal parts of Greenland that are now under ice. Why was the place given the name "Greenland" in the first place?
The bulk of the Ice Sheet sits in a depression in the ground so it cannot "slip" into the ocean. Complete melting of the ice sheet would require global temperature to rise by more than 3 degrees C and to stay that high for thousands of years. Decades have passed since climatologists disproved the urban myth that the Gulf Stream keeps Europe warm: the jet streams produce that warming. The ocean circulation is powered by winds that get their energy from the Sun so they cannot "shut down" unless the Sun disappears.
The IPCC and various independent sources give estimates of sea-level rise based on recent Greenland rates of melting ranging from zero to little more than ONE INCH over the current century. Only the Gory brain and the NYT talk of 23 feet.
If there is glacial shrinkage in Greenland it is more likely due to global cooling than global warming. It's just basic physics but Greenies ignore that: Since the temp of most glaciated areas is well below 0 degrees Celsius, the major determinant of glacial mass is precipitation. And what drives precipitation? Sea surface temperature! Warm seas give off more evaporation -- and hence precipitation -- and cool seas give off less. So lesser glacial mass and hence lesser precipitation implies global COOLING! And since the world has in fact been cooling for nearly two years now, some glacial shrinkage could be expected as a result of that.
