Scientists believe they might have discovered a large subsurface river in Greenland

Flowing rivers are probably not the first thing that comes to mind when thinking of Greenland and its seemingly endless amount of frozen vistas. Nonetheless, scientists uncovered that there might be a substantially large one underneath the surface, flowing from deep in its interior all the way to the northeastern coast.

Adapting cities to a hotter world: 3 essential reads

Heat waves can be deadly, especially when they combine high temperatures with elevated humidity levels that make the air feel even hotter. The impacts can be especially strong in cities, which often are several degrees warmer than nearby rural areas due to the urban heat island effect. These three articles from The Conversation’s archives describe steps that communities can take to adapt as climate change makes heat waves more frequent and intense.

Reforesting an area the size of the US needed to help avert climate breakdown, say researchers – are they right?

Reforesting an area the size of the US needed to help avert climate breakdown, say researchers – are they right?

Restoring the world’s forests on an unprecedented scale is “the best climate change solution available”, according to a new study. The researchers claim that covering 900m hectares of land – roughly the size of the continental US – with trees could store up to 205 billion tonnes of carbon, about two thirds of the carbon that humans have already put into the atmosphere.
