More Global Warming Evidence

polar bears on the edge of the ice packAnyone who has watched or listened to the BBC's news lately will know they have become rather absorbed by an event that happened two years ago, when a sizeable chunk of the Arctic ice sheet came loose, setting it on the same course as all other icebergs.

You can be reasonably sure that they will not be giving the same airspace to the latest scientific evidence on global warming. For, a new study into Atlantic hurricanes published in Nature has found little correlation with ocean temperatures. Just as with recent research on hurricane activity in the Atlantic, Kilimanjaro's melting glaciers, rising sea levels, and changes in polar bear populations, the hard facts conflict with the fashionable message being promoted by the climate change industry.

The research, which analysed sediment records going back 5000 years, instead discovered an inverse correlation with El Niño-related warming in the eastern Pacific. So, whenever El Niño picked up in the Pacific, then hurricanes were almost non-existent in the Atlantic. Conversely, whenever El Niño fell away, the storms kicked up again. In the words of one of the researchers, we need to "Consider the whole picture: On the centennial and millennial scale, El Niño seems to trump the warming processes in the Atlantic."
