The time for democracy has passed. Democracy isn't fast enough to respond to this challenge, assuming an educated electorate, and that assumption is invalid anyway.

Ice Age? Human caused or not if we enter an Ice Age we may wish we had saved some fosil fuels.

There have been those groups who claim we are moving into an ice age, or that the gulf stream will shut down, and various other claims. Personally, I think they are dis-info agents.
The historical record indicates that this warming period will last at least a 1,000 years, maybe 10.
I think if the ice on Greenland melts, and Antarctica, that deep ocean pressures will increase, and create increased volcanic activity. This could lead to the next ice age. We could possibly learn to tap into or control this volcanic activity.
According to a new study published in the journal Geophysical Research Letters, Greenland’s melting glaciers and ice caps sent 50 gigatons of water gushing into the oceans from 2003 to 2008. This comprises about 10 percent of the water flowing from all ice caps and glaciers on Earth. The research comes on the heels of a study last year that showed the ice sheets of Greenland and Antarctica are disappearing three times faster than in the 1990s, and that Greenland’s is melting at an especially accelerated rate. In the new study, scientists were able to put an even finer point to the ice-melt situation by separating out the glaciers and ice caps from the ice sheet, which blankets 80 percent of the island. What they discovered is that Greenland’s glaciers are actually melting more quickly than the ice sheet.
Given that Greenland experienced an exceptionally warm summer in 2012 and temperatures were higher than average this winter, 2013 is primed for more melting and massive icebergs. Last year’s ice-melt season lasted two months longer than the average since 1979, and this year’s is already off to an inauspicious start. It kicked off on March 13 with the sixth-smallest sea-ice area on record for Greenland, according to the National Snow and Ice Data Center. What will the new summer calving season bring?

It's called GREENland because it was Green when it was discovered. This has happened before in human history, even just since history started being kept. It's part of earth's cycle.
I won't argue whether people are speeding it up, etc. - but even if every human being had a zero carbon footprint & never produced any trash, this would still happen.
