OK, this is not about the actual global warming but a small side track...
I've heard that the tsunami waves in South-East Asia hit the shorelines with the kind of force that was enough to shake the whole planet, and actually the rotation of Earth "went back in time" for three seconds. I don't know how possible this is but those waves had lots of force in any case...
I've also heard that this shaking would have long-term effects on the weather on Earth, making the consequenses global warming worse.
Has anyone else heard about this???? I'd really like to know more....

Scientists say that the quake slightly affected the length of the day by altering the planet's shape:

Think about how a figure skater pulls in his or her arms while spinning, thus spinning faster and faster. Same principle.

Thanks, that made it much more clear... Just wondering what the long-term effects might be... But I guess we (or our grand-children) see it later on...

In order to change the earths shape t˙ere would have to be a quake 400,000
times larger the the earthquake that caused the tsunami
