‘”Greenland and Antarctica are very remote, and were considered to be big ice boxes that responded not very fast to climate change. We never developed a mechanism to observe them until we had satellites and lasers. Now we see some surfaces lowering up to 50 meters per year.” He repeated that number, to make sure Craig heard. “Fifty — five-zero — meters per year.” That’s a vertical drop of about 150 feet. In two years, that’s 300 feet. Then 450. Year after year — enormous piles of ice melting into the sea.’

‘A lot of water. Coming our way.’
