A. Summary Statement
Two frequently asked questions on global warming and hurricanes are the following:
- Have humans already caused a detectable increase in Atlantic hurricane activity or global tropical cyclone activity?
- What changes in hurricane activity are expected for the late 21st century, given the pronounced global warming scenarios from current IPCC models?
In this review, we address these questions in the context of published research findings. We will first present the main conclusions and then follow with some background discussion of the research that leads to these conclusions. The main conclusions are:
It is premature to conclude that human activities–and particularly
greenhouse gas emissions that cause global warming–have already had a detectable impact on Atlantic hurricane or global…
