The historic, climate-fueled wildfires in California have killed at least 26 people and scorched over 4 million acres so far this year. Cooler weather and rain forecast for later in the week could help provide some relief to firefighters as they combat the blazes, including the still-raging Glass Fire in Napa and Sonoma counties, which is now 26% contained.

Meanwhile, record heat in South America has triggered devastating wildfires in Paraguay, Brazil and Argentina. The Brazilian Amazon is seeing its worst fires in a decade, and the wetlands of Brazil and Argentina are also seeing a dramatic loss of wildlife due to record-shattering blazes.
