Fuck me running, I have to agree with Bratphart!

Therefore, we conclude that it is premature to conclude with high confidence that human activity–and particularly greenhouse warming–has already caused a detectable change in Atlantic hurricane activity. (“Detectable” here means the change is large enough to be distinguishable from the variability due to natural causes.) However, human activity may have already caused some some changes that are not yet confidently detectable due to the small magnitude of the changes or observation limitations, or due to limitations in modeling and physical understanding (e.g., aerosol effects on regional climate, uncertainties in simulation of Atlantic multidecadal variability).
We also conclude that it is likely that climate warming will cause Atlantic hurricanes in the coming century have higher rainfall rates than present-day hurricanes, and medium confidence that they will be more intense (higher peak winds and lower central pressures) on average. In our view, it is uncertain how the annual number of Atlantic tropical storms will change over the 21st century. All else equal, coastal inundation levels associated with tropical cyclones should increase with sea level rise as projected for example by
IPCC AR5. These assessment statements are intended to apply to climate warming of the type projected for the 21st century by prototype IPCC mid-range warming scenarios, such as A1B or RCP4.5.
