Earth's Ice Giants Accelerate Toward Collapse

Picture this: you're training for mountain rescues in Peru's Vallunaraju region when suddenly—crack—a house-sized chunk of glacier ice breaks loose and crashes down beside you. That's exactly what happened to a group of climbers last April. Their shock mirrors what climate scientists feel when they look at new data about our planet's ice sheets.

The numbers coming out of recent research don't just concern experts anymore. They should terrify anyone living near a coastline.

Turns out, those ambitious climate targets everyone's been talking about might not save us from catastrophic sea level rise after all. New findings suggest that even if we somehow pull off the miracle of limiting global warming to 1.5°C, we could still face runaway ice sheet melting that transforms coastlines forever.

Scientists Dig Deep for Answers

Researchers from multiple countries recently dove headfirst into a critical question: What temperature increase can Earth's ice sheets actually handle before they start falling apart? Their detective work involved piecing together clues from satellite data, climate computer models, ancient ice cores, deep ocean sediments, and—get this—octopus DNA that's been around for thousands of years.
