Remember that study the troll kept posting the abstract of in the previous AGW thread? Anyway, here is a quote on a different study by one of the authors.

“We found that the PDI is projected to increase in the 21st century in response to both greenhouse gas increases and reductions in particulate pollution over the Atlantic over the current century,” Villarini said. “By relating these results to other findings in a paper we published May 13, 2012 in the journal Nature Climate Change, we found that, while the number of storms is not projected to increase, their intensity is,” he said.

“Moreover, our results indicate that as more carbon dioxide is emitted, the stronger the storms get, while scenarios with the most aggressive carbon dioxide mitigation show the smallest increase in intensity,” he said.
