Hurricanes and global warming

The warming of the earth is having a terrible effect on earths weather specifically with hurricanes. The warming of the waters causes the hurricanes that occur to be more frequently more powerful. Within the last 100 years that we have measured hurricanes have gotten worse in severity and they cause more damage year after year. Not only that, but hurricanes maintain a lot more of their strength as they traverse waters because the waters are getting warmer and warmer meaning this lets hurricanes keep their strength while also gaining some more while at it. This also means that hurricanes will increase to throw more water onto shore and with already increasing sea level this will only spell disaster for anything that is close to coasts.

 "turning to future climate projections, current climate models suggest that tropical Atlantic SSTs will warm dramatically during the 21st century, and that upper tropospheric temperatures will warm even more than SSTs. Furthermore, most of the CMIP3 models project increasing levels of vertical wind shear over parts of the western tropical Atlantic (see Vecchi and Soden 2007). Both the increased warming of the upper troposphere relative to the surface and the increased vertical wind shear are detrimental factors for hurricane development and intensification, while warmer SSTs favor development and intensification. To explore which effect of these effects might “win out”, we can run experiments with our regional downscaling model."
