Sorry, Mr. Gore. Maybe the Antarctic ice pack won’t be melting after all.
Antarctica’s deep ocean waters are getting colder after years of warming, say researchers who have just returned from a Southern Ocean voyage aboard the German research vessel Polarstern.
And what’s this? Global Warming is stopping… temporarily?
Global warming will stop until at least 2015 because of natural variations in the climate, scientists have said.
Researchers studying long-term changes in sea temperatures said they now expect a “lull” for up to a decade while natural variations in climate cancel out the increases caused by man-made greenhouse gas emissions. …
Noel Keenlyside of the Leibniz Institute of Marine Sciences, Kiel, Germany, said: “The IPCC would predict a 0.3Â°C warming over the next decade. Our prediction is that there will be no warming until 2015 but it will pick up after that.”
He stressed that the results were just the initial findings from a new computer model of how the oceans behave over decades and it would be wholly misleading to infer that global warming, in the sense of the enhanced greenhouse effect from increased carbon emissions, had gone away. …
Writing in Nature, the scientists said: “Our results suggest that global surface temperature may not increase over the next decade, as natural climate variations in the North Atlantic and tropical Pacific temporarily offset the projected anthropogenic [manmade] warming.”
The study shows a more pronounced weakening effect than the Met Office’s Hadley Centre, which last year predicted that global warming would slow until 2009 and pick up after that, with half the years after 2009 being warmer than the warmest year on record, 1998.
Commenting on the new study, Richard Wood of the Hadley Centre said the model suggested the weakening of the MOC would have a cooling effect around the North Atlantic.
“Such a cooling could temporarily offset the longer-term warming trend from increasing levels of greenhouse gases in the atmosphere.
“That emphasises once again the need to consider climate variability and climate change together when making predictions over timescales of decades.”
But he said the use of just sea surface temperatures might not accurately reflect the state of the MOC, which was several miles deep and dependent on factors besides temperatures, such as salt content, which were included in the Met Office Hadley Centre model.
If the model could accurately forecast other variables besides temperature, such as rainfall, it would be increasingly useful, but climate predictions for a decade ahead would always be to some extent uncertain, he added.
So, bear that in mind, the earth getting cooler does not mean that you are not causing Global Warming. And though scientists can’t predict anything accurately about the future climate, you are not entitled to reject climate modeling’s conclusions.
