Our ability to cool the planet takes humanity into unchartered territory. In a new paper published today, researchers discuss the big unknowns in a post net-zero world.
Flooding from hurricanes like Irma in Florida can overwhelm sewer systems and spread pathogens in other ways.

It’s not just mosquitos. Flooding, extreme heat and other climate-related hazards are bringing people into contact with pathogens more often, and affecting people’s ability to fight off disease.
If global health care was a country, it would be the world’s fifth largest emitter. There are simple ways health care can reduce its emissions, starting with scans and gases.
Tidal marshes can build up their soil to keep pace with sea-level rises – up to a point. It turns out the point when the marsh is drowned matches the average rise when global warming exceeds 1.5℃.
Summer heat may be far from people’s minds here in Australia. But Europe’s ordeal is yet another sign changes in Earth’s climate have already reached dangerous levels.
For Pacific Islands, climate change trumps all other threats to their security. While they welcome Australia’s new emission targets, this is an issue of survival that demands greater ambition.
Communities already retreat from flooding and in the face of sea level rise. Is retreat from wildfires next, and what would that look like?
Using language that stresses the “seriousness” or “importance” of climate change in protests and campaigns can lead to counterintuitive results.

Global climate movements have espoused nonviolence, but some are adopting more radical tactics in light of the increasing threats posed by climate change.
New research finds nature restoration only marginally lowers global warming. This pours cold water on the idea of using carbon offsets to solve the climate crisis.
