The immigrant crisis Europe is reeling under is absolutely NOTHING compared to what we will see this century… Human civilization will be tested severely thanks to the most stupid and greedy among us… for 40 years corporate interests and partisan shills lied about the science and worked hard to keep the public ignorant of the facts.

And then there is the issue of positive feedback….

Methane is an extremely potent greenhouse gas, and up until now much of it has been preserved in deposits at the bottom of the ocean. Methane is estimated to be 23 times at potent of a greenhouse gas as CO2.

The most recent discovery of so-called methane plumes is off the coast in the Pacific Northwest. This is no small matter as methane is a much more powerful greenhouse gas than carbon dioxide and could potentially accelerate global warming.
The potential release of massive amounts of methane is no small matter. While carbon dioxide is the most well-known greenhouse gas, largely owing to the fact that it is emitted in massive amounts, and has been linked to human activity, it is actually a relatively weak greenhouse gas, at least compared to methane.

Methane is suspected for previously causing big and often sudden swings in the Earth’s climate. Much of the methane on Earth is actually trapped, frozen in the ocean, but as oceans warm up, this powerful greenhouse gas could be released. Global warming could thus accelerate.

However, Prof Ted Schuur from Northern Arizona University recognised that, despite the scientific progress, the fact was that thawing would occur and methane would leach into the atmosphere.
“Even if we stopped all emissions today, the Arctic has momentum where there is going to be more warming, more permafrost degradation and some carbon coming out already – we have started the ball rolling in some senses.”
“It is probably not triggering a runaway climate effect but it adds to our problem. It accelerates the problem, of climate change. To me that is worrisome because it makes the problem harder.”
Prof Schuur added that indirect impacts of warming were also speeding the thaw. In Alaska in 2015, there were near-record wildfires, which he said heightens the exposure of permafrost to warmer air.
