According to a new paper fires are rapidly growing in importance as a source of so-called "forest disturbance" around the world.  This isn't unexpected as climate change increases the length of fire seasons, creates dryer fuels, and creates more weather events conducive to fires.  It's too early to say whether a "tipping point" has been reached, and the picture is complicated by how rapidly our ability to directly observe global forests is improving, but it's an element of the climate roulette picture that bears close watching.
