Okay according to two new studies this is how the global warming enthusiasts say it’s going to work. Global warming is going to move the gulf stream (which circulates warm and across the Earth and makes cold water sink).. They say warming is going to mess up the gulf stream and other ocean circulation systems and cause the Northern Hemisphere to get cold. Simplified, their claim is that global warming is going to make things cold (you cant make this up).

The papers offer insight into how rapidly melting Arctic ice could slow or even temporarily halt the ocean’s normal circulation, with possible effects ranging from plunging temperatures in northern latitudes to centuries-long droughts in south-east Asia. A fictional version of this scenario was depicted in the 2004 disaster film Day after Tomorrow, although most scientists believe the movie’s vision of ice sheets over New York and Europe are highly unlikely.
One study, by three scientists from Germany’s Alfred Wegener Institute, uses computers to model how Greenland’s rapid thawing could affect the Atlantic meridional overturning circulation, the system that pushes cold, dense saltwater into the deep ocean and helps transport warm water northward, helping to warm Europe’s climate.
Well then…thank God the the ice caps are growing. A July 2015 article in the U.K. Telegraph called “How Arctic ice has made fools of all those poor warmists” reported:
In recent years there has been more polar ice in the world than at any time since satellite records began in 1979. In the very year they had forecast that the Arctic would be “ice free”, its thickness increased by a third. Polar bear numbers are rising, not falling. Temperatures in Greenland have shown no increase for decades
Forbes Magazine agrees:
Updated data from NASA satellite instruments reveal the Earth’s polar ice caps have not receded at all since the satellite instruments began measuring the ice caps in 1979. Since the end of 2012, moreover, total polar ice extent has largely remained above the post-1979 average. The updated data contradict one of the most frequently asserted global warming claims – that global warming is causing the polar ice caps to recede.
The timing of the 1979 NASA satellite instrument launch could not have been better for global warming alarmists. The late 1970s marked the end of a 30-year cooling trend. As a result, the polar ice caps were quite likely more extensive than they had been since at least the 1920s. Nevertheless, this abnormally extensive 1979 polar ice extent would appear to be the “normal” baseline when comparing post-1979 polar ice extent.
The Arctic Ice had a period of melting but as reported in Nature Geoscience:
However, we observe 33% and 25% more ice in autumn 2013 and 2014, respectively, relative to the 2010–2012 seasonal mean, which offset earlier losses. This increase was caused by the retention of thick sea ice northwest of Greenland during 2013 which, in turn, was associated with a 5% drop in the number of days on which melting occurred—conditions more typical of the late 1990s. In contrast, springtime Arctic sea ice volume has remained stable.
Whether or not the hypothesis about global warming will screw up the Earth’s watery currents is a moot point…because before that can happen the arctic has to melt…and it’s not melting.
A second paper, by a team of Texas scientists, sheds new light on how the Earth’s climate responded during a similar thaw from the planet’s geological past. About 12,000 years ago, rising temperatures at the end of the last ice age released huge volumes of cold freshwater, disrupting the ocean’s circulation systems and sending parts of the Northern Hemisphere back in to the freezer. Scientists refer to the era as the Younger Dryas period.
But what caused the thaw, there were no gas guzzlers back then, and approximately 12,750 years ago before big cars and coal plants, and 750 years before that thaw CO2 levels were higher than today. So if that melt was caused by greenhouse gases wouldn’t it have happen seven centuries earlier?
Here’s the good news these global warming theorists won’t mention. The earth hasn’t warmed in 18 and 3/4 years.
That’s right, the satellite monthly global mean surface temperature shows no global warming for 18 years 8 months since January 1997, that’s the year South Park debuted, Toni Braxton’s “Un-Break My Heart” was atop the Billboard singles list, Star Wars Special Edition was atop the movie box office and Hillary Clinton was trolling around the White House.
So this is nothing but another global warming scare tactic, as they see the polar ice caps growing they need an excuse and the best thing they can come up with is their standard—it’s all the fault of global warming.
