NASA's Earth Observatory released a natural-color satellite image of smoke from northwest wildfires as seen from space. Many of those fires broke out following a lightning storm last weekend.
As of September 11th more than 8.3 million acres had burned throughout the United States, according to the National Interagency Fire Center. That number doesn't count nearly 2 million acres that were prescribed burns.
Wildfires in Siberia
Russia is also experiencing a severe wildfire season. The fires are mostly burning in remote areas of eastern and central Siberia.
More than 17,000 wildfires have burned more than 74 million acres, according to researchers at the Sukachev Institute of Forest in the Russian Academy of Sciences.
