# Climate Tipping Points and Economic Cascades The Arctic is warming at roughly 4x the global average—a phenomenon called "Arctic amplification"—which destabilizes the jet stream and increases extreme weather frequency across mid-latitudes where 2 billion people live. Since 1970, global wetland loss has reached 87%, eliminating critical carbon sinks and flood buffers; wetlands sequester twice as much carbon per hectare as forests. This matters because climate systems operate through interconnected feedback loops: as permafrost thaws, it releases methane (a greenhouse gas 28-34x more potent than CO2 over a century), which accelerates warming, which thaws more permafrost. Understanding these thresholds is critical for policy because once certain tipping points pass—particularly Amazon rainforest dieback or West Antarctic ice sheet collapse—reversal becomes economically and physically impossible within human timescales, locking in trillions in infrastructure losses and displacement.
