Greenhouse Gases - Not The Only Force At Work

More Greenhouse gases in atmosphere, more the global warming.
Reduce the production of Greenhouse gases, reduce global warming.
Gives us a sense of control - however little - over climate, doesn't it?
Well if things were that easy.
The April 2010 issue of The Scientific American has news for you.
But first the conclusion in words of geoscientist Jeffery Dorale, "Greenhouse gases are clearly important to climate, but just as clearly they are not the only major forces at work."
Here's the piece of news ...

... [A] team of geologists conclude that, compared to today, sea levels were roughly one meter higher 81,000 years ago, when the world was thought to be experiencing an ice age that should have locked up water in glacial ice, which should have lowered sea level as much as 30 meters. ... What might have caused the sea-level climb remains unclear ... One thing is certain, however: the finding points to how complex the earth's climate is.

Hmmm.... Looks like the Climate Debate is not all shut and sealed up.
Just wondering .. Let's assume we drastically reduce production of the Greenhouse gases, suck out the Greenhouse gases from the atmosphere, stabilize or reverse the apparent global warming. And then discover that we have actually started something else. What if all our actions actually goes to destabilize the climate in ways we have no clue about?

After all the whole rigamarole is about making the climate suitable for human existence. Do you think the Earth give a s**t about whether humans survive or not?
