The heat wave stretching from California to Montana has caused dozens of fires and threatens the health of millions of Americans. Several cities including Oakland, San Francisco, Phoenix, Seattle and Philadelphia have broken heat records this summer. Californians and Nevadans have been told to conserve energy during the holiday weekend. The Mill Fire, which spanned over 4,000 acres as of Friday, was 40% contained as of Monday.

As humans navigate the effects of climate change, scientists warn that weather events are likely to become more common.
