Google is investing millions of dollars in an effort to use satellites and artificial intelligence to spot small wildfires before they become big ones. The company said in a blog post that it is teaming up with a satellite maker and a group of nonprofits to launch satellites next year that can pinpoint small blazes all over the world before they have gobbled up acres of land.

FireSat, a constellation of more than 50 satellites, will be able to detect wildfires as small as the size of a classroom, about 16 by 16 feet, Google said in an announcement.
