Arctic sea ice could disappear by 2030s, study warns.

A new study suggests that the Arctic could be ice-free in the summer by the 2030s, even if greenhouse gas emissions are curbed. The study found that an ice-free Arctic each September is likely already "baked" into Earth's climate system. The decline in sea ice affects Arctic communities and wildlife, and it helps regulate the planet’s temperature. An ice-free Arctic will "induce faster and stronger Arctic warming" and may increase extreme weather events. Arctic indigenous communities and animals that depend on sea ice will be strongly affected. Reduced sea ice will open the routes for ships and also favor the development of natural resources, but it can enhance the release of greenhouse gases into the atmosphere, further intensifying global warming.
