>> News article 1: "New Research Shows Humans Causing More Strong Hurricanes" In short, the Grinsted results suggest that by the end of the century, we will see 2 to 7 times more Katrina-like intense hurricanes. Moreover, their storm surges and associated damage will be even larger because sea levels will also be higher. In another important result, Grinsted et al. found that on average, the frequency of Katrina-magnitude storm surges doubles for every approximately 0.4°C average global surface warming. Since human-caused global surface warming over the past century has already exceeded 0.4°C, "we have probably crossed the threshold where Katrina magnitude hurricane surges are more likely caused by global warming than not." >> News article 2: "No Atlantic Hurricane by August in First Time in 11 Years" While water temperatures in the Atlantic, Caribbean and Gulf of Mexico are high enough to spark hurricane formation... Colorado State, which pioneered seasonal forecasts, retreated slightly on its outlook in an early August update, calling for 18 named storms. The National Oceanic & Atmospheric Administration also kept its call for an above-average season.
