A potential explanation for the global increase in tropical cyclone rapid intensification.

Tropical cyclone rapid intensification events often cause destructive hurricane landfalls because they are associated with the strongest storms and forecasts with the highest errors. Multi-decade observational datasets of tropical cyclone behavior have recently enabled documentation of upward trends in tropical cyclone rapid intensification in several basins. However, a robust anthropogenic signal in global intensification trends and the physical drivers of intensification trends have yet to be identified.

Heat and carbon coupling reveals ocean warming due to circulation changes.

Anthropogenic global surface warming is proportional to cumulative carbon emissions; this relationship is partly determined by the uptake and storage of heat and carbon by the ocean. The rates and patterns of ocean heat and carbon storage are influenced by ocean transport, such as mixing and large-scale circulation. However, existing climate models do not accurately capture the observed patterns of ocean warming, with a large spread in their projections of ocean circulation and ocean heat uptake.
