More dramatic climate extremes predicted in new scientific study
ScienceDaily (July 15, 2011) — Dramatic climate swings behind both last year’s Pakistan flooding and this year’s Queensland floods in Australia are likely to continue as the world gets warmer, scientists predict.
Researchers at the Universities of Oxford and Leeds have discovered that the El Niño Southern Oscillation (ENSO), the sloshing of the warmest waters on the planet from the West Pacific towards the East Pacific every 2-7 years, continued during Earth’s last great warm period, the Pliocene.
Their results suggest that swings between the two climatic extremes, known as El Niño and La Niña, may even have occurred more frequently in the warmer past and may increase in frequency in the future. Extreme ENSO events cause droughts, forest fires and floods across much of the world as well as affecting fishery production.
Reporting in the journal Paleoceanography, the team of geochemists and climate modellers use the Pliocene as a past analogue and predictor of the workings of Earth’s future climate.
The Pliocene (which lasted from 5 to 3 million years ago) had carbon dioxide levels similar to the present day, with global mean temperatures about 2-3ºC higher, so it is a useful test-ground for climate research.
Lead Scientist Nick Scroxton from Oxford University’s Department of Earth Sciences said: ‘We know from previous studies that the mean state of the Pacific during the warm Pliocene was similar to the climate patterns observed during a typical El Niño event that we see today.
‘However, until recently it was believed that a warmer Pacific would reduce the climate swings that cause the dramatic weather extremes throughout the region leading to a permanent state of El Niño. What we didn’t expect was that climatic variability would remain strong under these warmer conditions.’
Babylon the Great is about to take a hard fall. They are questioning what is causing so much revolt in nature, but some of Dawn Lucifer’s human agents try to sooth the public awareness by saying it is the earth going through a recycling stage that will eventually even itself out. For many, they will take no notice of the truth of what is about to befall them any more than they did in Noah’s pre-flood era, but all will be infuriated as the world they once knew is no longer hospitable.
