A diventare invisibili non sono i tornado ma poco a poco gli uragani, nonostante il GW:

The 2013 Atlantic hurricane season, which officially ends on Saturday, Nov. 30, had the fewest number of hurricanes since 1982, thanks in large part to persistent, unfavorable atmospheric conditions over the Gulf of Mexico, Caribbean Sea, and tropical Atlantic Ocean. This year is expected to rank as the sixth-least-active Atlantic hurricane season since 1950, in terms of the collective strength and duration of named storms and hurricanes.
Presto però comparirà il solito studio che dimostra con la sicurezza del 95% che la mancanza di uragani è dovuta al GW.
Si accettano scommesse.
