Climate study models worldwide glacier extinction risks under multiple warming pathways
Researchers mapped individual glacier loss across global warming scenarios, according to Hacker News.
The short version
- A study in Nature Climate Change examines extinction risks for individual glaciers across the globe using two standardized criteria.[Hacker News]
- The research models potential outcomes under warming increases of 1.5°C, 2.0°C, 2.7°C, and 4.0°C using three global glacier models.[Hacker News]
- Glaciers are deemed extinct if their area falls under 0.01 square kilometers or if remaining volume drops below 1% of initial levels.[Hacker News]
Key facts
- A Nature Climate Change study evaluates the fate of individual glaciers worldwide using two extinction benchmarks.[Hacker News]
- Extinction is marked when a glacier's area drops below 0.01 square kilometers or remaining volume falls under 1% of baseline values.[Hacker News]
- The research combines three global glacier models with General Circulation Models covering projected warming of 1.5°C, 2.0°C, 2.7°C, and 4.0°C.[Hacker News]
What remains uncertain
- The research does not account for glacier fragmentation as ice retreats, categorizing all ice within the original footprint as one glacier.[Hacker News]
