The consequences of Global Warming.
In the Northern Hemisphere the rapid increase in temperatures is causing millions of square klms of permafrost to melt. The amount of stored methane and CO2 in the permafrost is almost double the current CO2 in the atmosphere.
Release of Carbon from Melting Permafrost Could Trigger Rapid Warming

A study published last week in Nature Geoscience provides the first measurements of greenhouse gases from permafrost under Arctic lakes in Alaska, Siberia, and Canada. Although the research reveals that only a small amount of old carbon has been released in the past 60 years, it also suggests that much more could be released as the Arctic warms up faster than any other place on Earth.
“It’s a lit fuse, but the length of that fuse is very long,” said lead author Katey Walter Anthony of the University of Alaska. “According to the model projections, we’re getting ready for the part where it starts to explode. But it hasn’t happened yet.”
The scientists determined that the permafrost-carbon feedback is thus far small by looking at aerial photographs and using radiocarbon dating to determine the age of methane emitted from the Arctic lakes that are expanding to consume and thaw terrestrial permafrost. As that permafrost melts and decomposes, it releases ancient carbon as carbon dioxide and methane. Analysis of 113 radiocarbon dating measurements and 289 soil organic carbon measurements showed that approximately 0.2 to 2.5 petagrams of permafrost carbon was released as methane and carbon dioxide in the past six decades.
The billions of tons of carbon stored in permafrost are approximately double the amount currently in the atmosphere. Many researchers are concerned that emission of that stored carbon will contribute to warming that then contributes to permafrost thawing in an accelerating feedback loop.

I tried to explain to you it has all to do with the Sun and the 70 year climate change cycle and have given you links to follow but you are still very narrow minded about it all and just cannot accept to historical information.
You instead prefer to name calling to ridicule not my opinion but that of history in an attempt to silence any opposition.
What are you afraid of?....Being defeated with with your Green philosophy?......
Can you not have sensible discussion with the name calling or do you think that will help your cause?
