Global Warming Affects Land Ice December 16, 2008

I saw something in the news I wish I had known a few weeks ago. I made a posting about how I submitted a proof that manmade emissions are causing global warming. Today, I read how scientists at the meeting of the American Geophysical Union (AGU) have shown that 2 trillion tons of land ice have melted in the five years since 2003. Doing some quick calculations shows that this would take 6 x 10^20 joules of energy to accomplish. To put that into perspective, that is equal to the total energy output of 150,000 1 megaton (MT) nuclear weapons. You would have to detonate, and absorb 100% of the energy output, one such weapon every 17.5 minutes for five years to absorb that much energy.

This energy represents only the amount of energy needed to melt 2 trillion tons of ice and turn it into water. It does not include any heat needed to warm the ice to the freezing point and it does not include any warming of the water that may occur afterwards. It also does not include any energy that may have gone to heating any other part of the global environment.

Since this ice was not melting before, we can conclude that the system (i.e., the environment) did not have that excess heat in it before. Therefore, this heat was added to the system in recent years.

So, the question is: Where did this excess heat come from?

Naysayers will say all sorts of things, all unsupported, and will deny the overwhelming mountain of evidence that shows this is extra heat that is being stored in the environment via the greenhouse effect.

I feel my proof stands on its own and doesn’t need this additional information to make it more valid. I also don’t believe it would make any difference to JunkScience.com. One look at his website tells you he still would not accept the argument as proof.

But, it would have been nice to be able to include it, none the less.
