more than Los Angeles uses in one year. "
This is not perspective, this is brainless number-flaunting.
PERSPECTIVE would be telling how much sea level rise
is caused by a cubic kilometer of ice. The number is easy
to calculate but the press release writers did not seem to want
their readers to have it.
3,700km3 of water, or about 15 years of Greenland's loss. By how much
has the Caspian fallen in the last few decades? This could be done by
piping water from the black sea. There might also be the possibility to
reflood the Aral sea, which is disappearing.
Flooding the Quattara depression in the Sahara could take out about
1,000km3.
Both schemes would also increase local rainfall. The latter would also
provide hydroelectric power (though there would be some negative
consequences)
