Показать описание
Alaska’s Columbia glacier began rapidly retreating around 1980, and its leading edge has moved more than 20 kilometers inland. These images, captured by the joint NASA/U.S. Geological Survey Landsat satellites, were stitched together into a video to show the glacier’s dynamic evolution from 1972 to 2019.

This is a terrible video. You should have slowed it down enough to be comprehensible. This shows me nothing.

The very same thing happened about 14, 000 years ago. Just as now, nobody then lifted a finger to combat the problem. Disgusting. I personally blame Trump.
