Melting Mongolian ice reveals fragile artifacts that provide clues about how past people lived

From the high Yukon to the mountains of Central Asia, melting ice exposes fragile ancient artifacts that tell the story of the past – and provide hints about how to respond to a changing climate.

Antarctica is headed for a climate tipping point by 2060, with catastrophic melting if carbon emissions aren’t cut quickly

If emissions continue at their current pace, Antarctica will cross a threshold into runaway sea rise when today’s kids are raising families. Pulling CO2 out of the air later won’t stop the ice loss.
