Whether you live in the US or Canada, you may have noticed that daily temperatures have been in cool parts lately. (Me and my wife had a pellet stove just a week ago, something we did not do in June.) There is one explanation, say climate scientists. Usually there is a mass of cold air over the Arctic but this year's temperature at the top of the globe is as much as 40º Fahrenheit higher than normal .
air and its transmission to North America, becoming colder and cooler than normal. How bad is that? This tweet from Bill McKibben makes it a crystal.
This spring, Greenland is melting 3x faster than the early phases of global warming. https://t.co/GlWf7cT8kJ

It's getting worse. A team of researchers from the University of Alaska Fairbanks recently traveled to the Canadian Arctic and discovered the permafrost with a thawed 70 years earlier than predicted. They are amazed by how quickly the order of unusual hot summer is abolishing the higher layers of giant frozen solid underground ice blocks for millennia, according to a report on The Guardian . "What we have seen is amazing," said Vladimir Romanovsky, a professor of geophysics at the university, Reuters . "It's a sign that the climate is warmer than at any time in the last 5,000 or more years."
The research of the University of Fairbanks took place more than a decade, but when the plane was research team was riding this year under clouds near the abandoned military installation of 300 kilometers north of Nearest civilization, they are surprised to see the uninterrupted frozen tundra they expect to lose.
In its place is a wavy sea of hummocks-high depressions and ponds known as thermokarst. Plants, once sporadic, flourish. Professor Romanovsky said the scene of his scene was the result of a bombardment. "It's a coal canary," said Louise Farquharson, a postdoctoral researcher and co-author of the study. "This phenomenon is likely to affect a wider region and that's what we will look forward to next."
What is the big deal about permafrost? It's just frozen water, is not it? Yes. but it also consists of many methane quantities. And the methane, you might think, is a powerful greenhouse gas that is 80 times stronger than carbon dioxide when it comes to environmental warming. More methane means higher temperatures which means more melt and higher temperatures. This is what is known as a feedback loop and it presages catastrophic environmental changes are happening now, not decades or centuries in the future.
"Thawing permafrost is one of the tipping points for climate breakdown and this occurs before our very eyes," said Jennifer Morgan, executive director of Greenpeace International, telling the Guardian . "This early pouring is another clear sign that we should decarbonize our economies, and immediately."
No Ice Flakes Fallen
Other climate researchers such as Zachary Labe, in the University of California Irvine report have an unprecedented amount of ice melt over the Arctic Ocean at this time of year. Greenland levels are also melting at this time of year and may set a record. It is "another series of extreme events that are consistent with the long-term trend of warming," says Labe. Usually, this digestion is widespread over the ice sheet does not occur until the summer, if even then.
Weather satellites monitor the sea ice in the Arctic since 1979. Currently, ice coverage is the lowest record for mid-June. The area of ice is especially falling on the Arctic Ocean side adjacent to the Pacific Ocean. "It's quite noticeable how much open water is there," Labe said.
Bulging zones of high pressure in the Arctic help unusual heat and intensity, according to the Washington Post . They put the cold air usually placed in that region in the middle of latitude in North America, like a refrigerator door left open.
This is the reason for the overwhelming diversity in the jet stream recently. "The jet stream this week is one of the worst I've ever seen!" Jennifer Francis, a leading researcher who studies changes in the Arctic and mid-latitude weather and a senior scientist at the Woods Hole Research Center. He suggested that Arctic conditions could be played on an extreme jet stream pattern that shook the tornado and flooded the central US in the last two weeks of May. "We can not say that the rapid heating of the Arctic brings the particular pattern, but it certainly is consistent with that," Francis said.
Too Late Baby, Too Late
Meanwhile, the putative president and the Unfaded Republican jellyfish continue to follow the fossil fuel industry preferences. The former brushes off the climate warnings with a smug "I do not believe it," as if anyone could say that 2 + 2 = 4 were fake news if they wanted to. The latter is deeply concerned with maintaining the dollars flowing from the Koch Brothers who care.
The evidence suggests that the world has entered a period of unprecedented climate, which sees the average global temperatures rising above 1.5 º C, but global leaders work alongside none to address the issue. Israel dedicates a new community to Donald Trump. England is praying for a new Falklands war considering Brexit's problems. And the US state secretary Mike Pompeo is launching around the world that teaches how the Arctic melting ice is a wonderful thing because it will be easier to drill for oil and gas region.
Any hope that the world can limit Global warming at only harmful levels is rapidly sank. In fact, it may be too late for people to do anything meaningful about the rotten, stinking mess they did, reminding me of this prophetic ditty by Yip Harburg:
God did the world in six days flat.  At the seventh, He said, "I'm going to rest."
So He allowed the object to orbit swing,
To give it a dry run test.
A billion years ago,
Then he saw the drop of the glitter.
His spirits fell as he said,
"Well, this is a six-day job."
