Sweden’s shrinking southern shorelines need to be saved with sand, according to researchers from Lund University.

Frequent burning over decades reduces the amount of carbon and nitrogen stored in soils of savanna grasslands and broadleaf forests, in part because reduced plant growth means less carbon being drawn out of the atmosphere and stored in plant matter.

Scientists analyzed 27 extreme weather events from 2016 and found that global warming was a “significant driver” for most of them. We look at five cases.

Driven by fierce Santa Ana winds, four intense fires near Los Angeles grew to engulf more than 115,000 acres Thursday, and officials say residents should be prepared for even more strong winds through Friday.
