It's not clear boreal feedbacks are even necessary to lighting off tropical biomass (fire once again), but they'll certainly speed the process way up; if that does happen in turn we're on our way to a hyperthermal (with some lag since the oceans have to warm enough to trigger a self - sustaining loss of shallow methane hydrates).
