NASA Provides New Perspectives On The Earth's Changing Ice Sheets

Posted December 21, 2006 6:55 AM

From ScienceDaily Headlines:

It is widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. What most do not know is that until just six years ago, we had no real way of measuring whether the ice sheets were shrinking or growing, or at what rate. Waleed Abdalati of NASA's Goddard Space Flight Center, provides an overview of recent findings at the American Geophysical Union meeting, December 11 at 7:15 p.m. EST (session C14B-02).

Planting billions of trees, every citizen of the world should plant at least 10 fruit trees each weekend. That's the obvious solution mankind has to take, because once crossing the CO2 carboniferous trigger threshold, if we let Mother Nature take this decision, then she will populate this word with a ferocious carboniferous forest where we will have no place to walk, and where the only way to travel will be by air.

And if everyone would just send me a dollar, I'd be a billionaire.

Any solution must take into account human nature, or it is not going to help. There is no way that people will plant 10 fruit trees each weekend, and when they fail to do so, shall we complain and throw up our hands?

As an animal, we humans work in very predictable ways. We gather in packs, we fight for position, we look out for our own interests. We also look after our wounded, protect our young, and are capable of instants of extreme sacrifice when the occasion calls for it. It is not in our nature to habitually and regularly make sacrifices without clear reward. Don't take my word for it, read about game theory, it explains it in a more quantitative way.

Asking us to go against our very nature is akin to asking gravity to "turn off" for a second. We must study our nature, "know thyself" if you will, and only by selecting a solution that is compatible with our nature will we succeed. Blissfully wishing for people to plant trees because its the right thing to do, despite the fact that it clearly flies in the face of human nature is a self serving opiate to used to delude ourselves that we are not the problem. A rationalization to handle the guilt. Others merely contend there is no problem at all, neither coping mechanisms are helpful.

Its like making $100 laptops for people with no water. Sure the purpose is to help solve the digital divide, but when people are dying of malaria and dysentery, and are being mutilated and destroyed in tribal warfare, they don't care about the digital divide. So who do we serve when we make $100 laptops for the third world, them or ourselves? The same goes for impractical solutions to global problems.

Its good to care about the issue and to be idealistic, but if you truly want to help, you must first be honest about our strengths and weaknesses as a species. Then try to use our strengths to solve the problem rather than merely choosing a solution that exposes our weaknesses.

Roger, I just had to tell you, that was a beautifully written response.

Yes, I also admit that this response to me is realistic. We human beings are no more intelligent than bacteria droved by chemical incentives.
