After reading a little Ray Kurzweil (I know he is a futurist)... I feel we do have the tech, and will have even more over the next 50 years, to combat this problem. "Those projections are based on linear thinking, as if nothing's going to happen over the next 50 or 100 years. It's ridiculous. For example, we're applying nanotechnology to solar panels. The cost per watt of solar energy is coming down dramatically. As a result, the amount of solar energy is growing exponentially. It‘s doubling every two years, reliably, for the last 20 years. People ask, "Is there really enough solar energy to meet all of our energy needs?" It's actually 10,000 times more than we need. And yes you lose some with cloud cover and so forth, but we only have to capture one part in 10,000. If you put efficient solar collection panels on a small percentage of the deserts in the world, you would meet 100% of our energy needs. And there‘s also the same kind of progress being made on energy storage to deal with the intermittency of solar. There are only eight doublings to go before solar meets 100% of our energy needs." (-RK) With the coming of many new nanotechnologies it will actually be possible to consume the methane in the atmosphere and actually cool the earth. There is a much larger list of helpful technologies on the way for this sort of thing. The real part of the problem is implementation. That will take a global change in politics and getting the proponents of global warming (those huge corporate opportunists that stand to gain from our global misfortunes) out of Washington. If that will happen or not is highly speculative since Americans are easily persuaded to vote against their own interests...

Although there may only be satellite data of sea ice coverage going back 25 yrs, other records with global temperature proxies go back much further. Greenland ice cores go back as far as 123,000 yrs and Vostok goes 400,000 and I think another antarctic core goes back up to 800,000. The global carbonate rock record gives us another temperature proxy reaching back to ~65ma. And how is global warming a scam? The globe, currently, is warming. Global warming. And although this film was clearly not on the conservative side of the climate change debate, I don't agree that it appeared to "think it knows it all." It presented some facts (yes, facts) about warming/albedo and warming/methane release positive feedbacks, but it made no projections of earth's fate and in fact never once iterated that current climate change is anthropogenic in origin.

While some would call Global Climate Change a theory, others would call it a proven set of facts. Opinions differ vehemently. Let us consider Global Climate Change to be both a premise that the environment of the world as we know it is slowly, but very surely increasing in overall air and water temperature, and a promise that if whatever is causing this trend is not interrupted or challenged life on earth will dynamically be affected.

The prevailing counter opinion is that all that is presently perceived to be Global Climate Change is simply the result of a normal climactic swing in the direction of increased temperature. Most proponents of this Global Climate Change ideology have definitive social and financial interests in these claims.

Global Climate Change is real. It is not the result of a natural climatic adjustment. It is a quantifiable set of environmental results that are in addition to any normal changes in climate. That is why the effects of Global Climate Change have catastrophic potential. Global Climate Change is the straw that breaks the camel’s back. It is the difference between a category three hurricane and a category four. Global Climate Change is an imbalance of nature.

The premise of Global Climate Change is that industrial growth coupled with non-structured methods we as humans use to sustain ourselves has created a situation where our planet is changing by the minute. We have seemingly negatively effected our environment by a cycle of harmful processes that now seem to be feeding upon themselves to exponentially increase the damage to our ecosystem.

They think they know it all. When they only have 25y of data. The earth is much older than that and will be hear long after we all nuke our self. it just trying to reinforce global warming. which is the biggest scam ever.
