Detection and Attribution
There is growing evidence supporting the conclusion that AGW is already having an effect on extreme weather events, and those impacts are not beneficial to humanity or to the earth's ecosystems. But the process of arriving at those conclusions is complex, and different types of extreme weather are affected by AGW in different ways. While there is a clear (and obvious) link between AGW and extreme heat, heatwaves, droughts, and flooding, the effects of AGW on other extreme weather are far more difficult to determine. For instance, it may be that AGW is only affecting which parts of the US are more likely to be affected by tornadoes without impacting their frequency. The effect of AGW on Tropical Cyclones (TCs) has been extensively studied, and it appears that there is growing evidence that there are clear connections between AGW and hurricane activity, but I see many reported connections (or lack of connections) misstated by the media, politicians and "think tanks."
