Most climate scientists agree the main cause of the current global warming trend is human expansion of the "greenhouse effect". Wildfires are increasing and wildfire season is getting longer in the Western U.S. as temperatures rise. Higher spring and summer temperatures and earlier spring snow-melt result in forests that are hotter and drier for longer periods of time, priming conditions for wildfires to ignite and spread. Dangerously hot weather is already occurring more frequently than it did 60 years ago and are expected to be more frequent.
