I ghiacciai si sciolgono davvero Lo dimostra un nuovo studio pubblicato su Science, che incrocia i dati provenienti da 10 diverse missioni satellitari. Dal '92 la fusione dei ghiacci avrebbe provocato un innalzamento delle acque di oltre 11 millimetri Leggi l'articolo su Galileo (http://www.galileonet.it/articles/50bcbf3aa5717a2ac0000017) Credits immagine: Ian Joughin
This May 30, 2012 image provided by Ian Joughin shows an iceberg in or just outside the Ilulissat fjord, that likely calved from Jakobshavn Isbrae, the fastest glacier in west Greenland. Polar ice sheets are now melting three times faster than in the 1990s, but so far that's added just less than half an inch to Glaciers
Largest Glacier Break Video: Insofar as evidence of climate change goes, it's hard to beat watching a glacier comparable in size to Manhattan disintegrate in front of your eyes.
FACTS 1. Avg temp increased 1.3º in past 100 yrs. Previously took 5000 yrs for this same increase. 2. Polar ice sheets are now melting three times faster than in the 1990s.

One solution to the melting ice cap: Refreeze it. It wouldn’t even cost that much! http://news.nationalpost.com/2012/12/10/one-solution-to-the-melting-ice-caps-refreeze-them-it-wouldnt-even-cost-that-much/
An iceberg in the Ilulissat Fjord which likely calved from the Jakobshavn Isbrae, Greenland's fastest-moving glacier. Legend has it that this glacier produced the iceberg that sunk the Titanic.
The Environmental Protection Agency has the authority to address climate change. That shouldn’t be a controversial statement, but in some quarters, it is.
