We can get off most fossil fuels within 20-30 years if we put a concerted effort into solar, wind, fuel cells, electric cars, algae biofuels, and new nuclear technologies.
We also need a new national smart power grid to move electricity.
We can use a carbon tax on fossil fuels to pay for it, and it'll provide millions of JOBS that can't be exported.
Europe & China are ALREADY doing this and America will lose out in future green energy technologies, if we don't.
We owe it to our grandchildren.

I am not going to deny that the temprature of Earth has been steadily rising over the past several decades. You simply need to look at actual temprature measurements and the warming of our planet since the late 60s/early 70s is undeniable. This man does say however that you cannot denounce global warming if you have say, a decade or two of cooler average global tempratures, which I agree with. But what makes the opposite of this true? Why does 3 or 4 decades of tempratrue increase confirm an unstopable increase in global temprature for the next 100 years? I feel he is being a little hypocritacle in that regard.

I also have a problem with ice core sampeling. The entire premis of ice core sampeling is that when the air is encapsulated, it becomes a perfectaly closed system, which is simply not true. Gasses traped in the ice will become diluted over time through small quantities of liquid water passing through the air pockets, as well as the cold tempratures and pressure altering the co2 composition within the ice. The point im making is that gas pockets in old ice are not an accurate representation of ancient atmospheres.

In order to accept your theories, you'll have to provide links to peer-reviewed scientific publications that support your supposition. Please?

NEWS:
Methane Releases from Arctic Shelf May Be Much Larger and Faster Than Anticipated

NSF, National Science Foundation - March 4, 2010.

Research results, published in the March 5 edition of the journal Science, show that the permafrost under the East Siberian Arctic Shelf, long thought to be an impermeable barrier sealing in methane, is perforated and is starting to leak large amounts of methane into the atmosphere. Release of even a fraction of the methane stored in the shelf could trigger abrupt climate warming.

As Martin Heimann writes in Science:

Wetlands and permafrost soils, including the sub-sea permafrost under the Arctic Ocean, contain at least twice the amount of carbon that is currently in the atmosphere as carbon dioxide. Release of a sizable fraction of this carbon as carbon dioxide and/or methane would lead to warmer atmospheric temperatures, causing yet more methane to be released. It would thus create a positive feedback loop that amplifies global warming.
