=== Wildfires and Forest Dieback ===
Terrestrial forests act as a primary carbon sink, but shifting precipitation regimes and prolonged heat waves are altering their stability. Severe drought stresses trees, reducing their photosynthetic carbon uptake and making them highly susceptible to pests (like bark beetles). 

Furthermore, the desiccation of the landscape provides vast amounts of dry fuel, leading to an increase in the frequency and intensity of wildfires, particularly in the boreal forests of North America and Eurasia. When these forests burn, they rapidly rapidly release decades or centuries of stored carbon back into the atmosphere in days, transitioning ecosystems from net carbon sinks into active carbon sources.
