Absent new, more ambitious climate policies, the world is headed for a magnitude of climate change that would put about 2 billion people at risk of extreme heat by the end of the century, a new study finds.
Why it matters: Limiting global warming to the Paris Agreement's target of 1.5°C (2.7°F) above preindustrial levels would yield a five-fold reduction in the population exposed to unprecedented heat by the end of this century.
An updated, authoritative United Nations disasters analysis out this morning shows there were nearly 12,000 disasters attributable to extreme weather and climate-related events during the 1970-2021 period, Andrew writes.
The big picture: Such disasters are becoming more expensive, with a total bill of $4.3 trillion and rising. At the same time, however, they are getting less deadly.
