Abstract
Climate physics indicates that warming climate is a likely cause of extreme weather and more frequent and intense climate events. These extreme events can disrupt terrestrial carbon dynamics dramatically by triggering ecological disturbances and potentially forcing climate–carbon feedbacks. In this paper we synthesize the findings of 26 papers that focus on collecting evidence and developing knowledge of how extreme events disturb terrestrial carbon dynamics.

understanding feedback between climate dynamics and the carbon cycle is extremely important in understanding 21st century climate change extreme events such as droughts hurricanes heat waves forest fires anomalous freezing events and insect outbreaks lead to ecological disturbances that kill living vegetation and thus have the potential to strongly alter carbon exchanges between the biosphere and the atmosphere in this article we synthesize and review a collection of papers from our focus issue on extreme events in the carbon cycle the diverse papers in this issue are based on flux observations forest inventories remote sensing numerical modeling theoretical and experimental approaches they expand our basic understanding of the effects of extreme events of carbon cycle and point the way forward for continued research the linkage between
global warming in extreme weather is based on the physics of climate as error forms that its capacity to hold water increases the extra vapor in the atmosphere can trigger larger rainstorms in the worst case lead to flooding in more violent storms at the same time the atmosphere can take longer to recharge leading to longer times between rain events and increasing the potential for drought extreme weather events increased
