How Close Are the Planet’s Climate Tipping Points?
Human-driven warming is steadily reconfiguring [[Earth]]’s climate, and scientists warn that several large natural systems could flip past irreversible thresholds with sweeping consequences. The article surveys possible tipping points — mass death of [[coral reefs]] from repeated bleaching; abrupt thawing of [[permafrost]] that releases carbon and methane; collapse of the [[Greenland]] ice sheet and breakup of the [[West Antarctic Ice Sheet]] that would raise seas for centuries; a sudden shift in the [[West African monsoon]]; large-scale loss of the [[Amazon rainforest]]; and a slowdown or shutdown of the [[Atlantic Meridional Overturning Circulation]]. Each carries deep uncertainties in timing and likelihood — from changes already unfolding to processes that could take centuries — but more CO2 and continued land-use change increase the odds of crossing these thresholds.
