Global warming 'could stop NATURALLY within ten years,' say scientists

Global warming may stop over the next decade because of natural climate cooling, scientists now claim.

German scientists behind the study have warned Governments looking to save money not to use it as an excuse to cut back on preventative action.

Noel Keenlyside, a climate researcher at the Leibniz Institute of Marine Sciences in Germany who led the study, said: "The natural variations change climate on this timescale and policy makers may either think mitigation is working or that there is no global warming at all."

Climate researchers have long predicted more greenhouse gases in the atmosphere would spur a general warming trend over the next 100 years.

But the latest research study in the journal Nature claim natural variations will overwhelm any human warming effects in the short-term.

The German team made a computer model that takes into account natural phenomena such as sea surface temperatures and ocean circulation patterns.

They checked their work by producing a set of forecasts using data recorded over the past 50 years and found the retrospective forecasts were accurate.

Mr Keenlyside said: "This is important because policies are made in the short term.

"Our results show we might not have as much change in climate over the next 10 years."

The findings contradict the latest United Nations climate panel report which predicted temperatures would rise between 1.8 and 4 degrees Celsius this century, in part because of fossil fuels that produce carbon dioxide, the main greenhouse gas.

Scientists say rising temperatures could cause seas to rise sharply, glaciers to melt and storms and droughts to become more intense.

These in turn may force mass migrations of climate refugees.

But Mr Keenlyside said one possible reason for the relative short-term cooling effect in the next decade is the predicted weakening of a system that brings warm water northward into the North Atlantic and offsets an expected rise in greenhouse gases.

The findings are already being accepted by respected weather experts.

Richard Wood, an expert at the Met Office, wrote in a respected publication: "The first attempts at decadal prediction suggest that reasonably accurate forecasts of the combined effects of increasing greenhouse-gas concentrations and natural climate variations can be made."

Al Gore could not be reached due to being in his private jet destroying the atmosphere he wants to save (and getting a nice profit from the companies who just KNOW they can do it)...

From what I saw the other night on the Discovery Channel. A few scientist went into Alaska and the north pole area and found very disturbing news in the ice melts and the bogs and lakes with methane gas bubbling up into the air. They went to about 4 or 5 locations in 3 or 4 person teams in different fields of study, regrouped and set out again. The study is new and will be out in about 6 months or more. But they also said much more needs to be studied.
One results of the study was polar bears are going to go like the Dino's in the past.
Another was each glacier was receding much faster that first thought. They had all the pixes from earlier studies and made more from the very same spots.

One ice sheet had receded about a mile or more. The locals they spoke with added much info to the study. And the ice melt run off into the ocean was like water falls at two sites very large water falls. This fresh water will by itself change ocean currents and will result in weather patterns changes.

My thought was why hasn't any water bottling company gone there to get this fresh water to bottle and help slow the amount going into the ocean

They went down into a water hole from melt to the very bottom of a glacier and saw the melt moving the entire ice sheet along, the first time this has been seen and taped. But this is just one study. But I believe we are in for a wild weather ride because of it. Just IMHO!

It is a very misleading headline. In the link there are these bits that have been somehow missed from the original post:-

'Global warming will be "put on hold" over the next decade because of natural climate variations, scientists claim.'

'But scientists say rising carbon dioxide levels caused by man will send temperatures up again after the natural trends peak and will continue to rise in following decades.'

They are not saying GW will stop, they are saying it may slow down a bit for a few years and then continue right on going.

So in other words, we should put aside global warming until it actually starts happening?

In the 70's we were advised to dismiss the impending Ice Age until it started happeing too.

You 'science geeks' are just like everyone else, chasing profit.
