Guam is "expected to take a direct hit" from Typhoon Mawar after strengthening into a dangerous Category 4 storm in the Pacific Tuesday, the National Weather Service office in the U.S. territory warns.
The latest: The eye of the storm was on track to pass Wednesday evening local time over central or northern Guam, which has a 168,000-strong population and is home to three U.S. military bases. NWS Guam issued a flash flood warning for the entire island through at least Thursday morning due to heavy rainfall.
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.
