In Alberta, Canada, forecasters say rain and cooling temperatures should help firefighters bring a record-smashing spring wildfire season under control, after some 2.3 million acres burned. Smoke from the fires has prompted air quality alerts in U.S. states including Colorado, Idaho, Montana and Utah. 
On Monday, the World Meteorological Organization reported extreme weather events have caused some 2 million deaths since 1970, with over 90% of those killed from the Global South.
