Earth-shaking Event Changes the World

In the press release “NASA Details Earthquake Effects on the Earth” we are told

NASA scientists using data from the Indonesian earthquake calculated it affected Earth's rotation, decreased the length of day, slightly changed the planet's shape, and shifted the North Pole by centimeters. The earthquake that created the huge tsunami also changed the Earth's rotation.


They also found the earthquake decreased the length of day by 2.68 microseconds.

I wonder how this will affect global warming?

The net effect was a slightly more compact Earth.

We're always improving efficiency.
