00:00More than 12 trillion tons of ice have been lost from Greenland and Antarctica since 1979,
00:07according to a major scientific study tracking decades of changes in the world's two largest ice
00:13sheets. Scientists say most of the loss has been driven not by warmer air but by oceans warming
00:20around the ice sheets. So from our satellite observations we've seen that there is a clear
00:28trend and that the ice sheets are losing more mass and it has been increasing from decade to decade
00:35especially if you look at the ice being discharged to the ocean and that's quite clear that there is
00:44a link to climate change and that because of the warming air temperatures and ocean temperatures
00:49the ice sheets have been losing more mass than they used to.
00:56The studies say ice loss accelerated sharply in the 2010s with scientists pointing the effects
01:03could continue for decades.
01:0911.3 trillion tons of ice but then when you convert to an average global sea level it's only 3
01:15.2
01:16centimeters but even if it seems like a small number we know that every centimeter of sea level rise
01:22rise matters and that because for every centimeter of sea level rise about two to three million people
01:27would be at further risk of annual coastal flooding.
01:33Scientists estimate each centimeter of sea level rise put another two to three million people at risk of annual
01:39coastal flooding.
