A cold Arctic summer has lead to a million more square miles of ocean covered with ice than at the same period last year – an increase of 60 per cent.
The rebound from 2012’s record low comes a few years after BBC predicted that global warming would leave the Arctic ice-free in summer by 2013.
As The Telegraph writes, more than half the size of Europe ice cover now stretches from the Canadian islands to Russia’s northern shores, days before the annual re-freeze is even set to begin.
The Northwest Passage from the Atlantic to the Pacific ocean has been blocked ice during the whole year, forcing some ships to change their routes.
According to leaked information sent to the UN Intergovernmental Panel on Climate Change (IPCC), some sientists believe that the world on its way to a new era of cooling that will not end until the middle of this century.
By the way, the new predictions have fored the UN’s climate change’s body to hold an emergeny meeting, and the the IPCC is expeted to report on the situation next month. A pre-summit meeting will be held a few weeks later.
However, the leaked documents will show that the governments who fund the Committee are demanding 1,500 changes to the Fifth Assessment Report – a сomprehensie study which is released every six years – as they claim its current draft does not properly explain the pause.
“The extent to which temperatures will rise with carbon dioxide levels and how much of the warming over the past 150 years, a total of 0.8C, is down to human greenhouse gas emissions are key issues in the debate,” The Telegraph writes.
“The IPCC says it is “95 per cent confident” that global warming has been caused by humans – up from 90 per cent in 2007 – according to the draft report,” the publication adds.
This claim is highly debated now. US climate expert Professor Judith Curry said a day ago: “In fact, the uncertainty is getting bigger. It’s now clear the models are way too sensitive to carbon dioxide. I cannot see any basis for the IPCC increasing its confidence level.”
The expert also spoke of long-term cycles in ocean temperature, which have a huge impact on climate change and suggest the world may live again a period similar to that from 1965 to 1975, an epoch of cooling.
Professor Anastasios Tsonis, of the University of Wisconsin, was among those who investigated the ocean cycles.
He said: “We are already in a cooling trend, which I think will continue for the next 15 years at least. There is no doubt the warming of the 1980s and 1990s has stopped.”
“The IPCC claims its models show a pause of 15 years can be expected. But that means that after only a very few years more, they will have to admit they are wrong.”
Professor Curry suppose that the ice’s behaviour over the next couple of years would be crucial, both for understanding the climate and for future policy. “Arctic sea ice is the indicator to watch,” she said.
