An international team of polar scientists has produced the most complete picture of ice loss from Greenland and Antarctica to date.

The Earth has had at least five major ice ages, and humans showed up in time for the most recent one. In fact, we’re still in it.

Suicide Basin, an ice-dammed lake on an arm of Mendenhall Glacier, has filled up with meltwater and sent destructive surges of water into Juneau for 3 straight summers.

They’re called rock glaciers, and they might not look like much, but they’ll continue to provide meltwater after the world’s iconic white glaciers are gone.

Scientists say the trend is not only a "considerable risk" to shipping but is also reshaping deep-sea habitats.
