Global warming to spark increase in US wildfires

Breaking Earth News
USA
Much of the north-western US wilderness is already a tinderbox, but thanks to global warming, wildfires will be scorching even more land every year by the end of the century. Warmer-than-average ocean temperatures in the North Pacific create more low-pressure weather systems than cooler waters do, pushing jet stream circulation north into Canada. This leaves room for high-pressure systems to move in from the south, bringing drier and hotter air to the north-west. Calculations show the amount of land burned annually in the north-west will grow from under a million hectares in 2002 to nearly 2 million hectares by 2080.
