Does this new method perform better than the IPCC?

NIWA, where are you?

The Southern Oscillation Index (SOI), according to the Australian Bureau of Meteorology, is calculated from the monthly or seasonal fluctuations in the air pressure difference between Tahiti and Darwin.

In July last year three climate scientists published a paper in the Journal of Geophysical Research. “Influence of the Southern Oscillation on tropospheric temperature” concluded that nature, not man, was responsible for “recent global warming.”

The paper, by John McClean, Chris DeFreitas and Bob Carter, shows that what the SOI does now, the temperature will do in between five and eight months’ time.

Simple. But does it work to predict global temperatures? Read more… »

How Mother Nature Fooled the World’s Top Climate Scientists

I’ve reposted Roy’s announcement because the book sounds stunning and because of the penetrating comments he makes, such as:

The Great Global Warming Blunder: How Mother Nature Fooled the World’s Top Climate Scientists. By Dr Roy Spencer, who’s been a tenacious sceptic of anthropogenic global warming for many years. Click for previews at Amazon.

The polar bear is now a threatened species under the Endangered Species Act. It’s a major victory for environmentalists, who have been looking for a legal back door to limit carbon-dioxide emissions, but Roy Spencer reflects on what else it might mean. Will the bears now be saved? Did they ever need saving? What about freedom and prosperity? more…

History and reason say no—so can we greatly alter the climate? Study history, for it says the climate has changed like this before. Study science, for it says that puny man has no effect. more…

Spencer raises a scientific point of order in the global warming debate. Are there not many advantageous effects of CO₂? Are there any negative effects? more…
