There are suggestions that in some instances this might be the case. Cyclones, floods, and swarms of desert locusts also increased humanitarian needs in Eastern and Southern Africa. [7] Thailand's southern provinces also saw seasonal flash-flooding towards the end of the year, although these were not as destructive as the floods in the more northerly provinces.

Three classes of flood duration (i.e., short: 1–7, moderate: 8–20, and long: 21 days and above) are also considered for this analysis. A 2015 study suggests increasing odds for potential flooding similar to the 2011 flood intensity to occur in the future. More extreme weather, such as blizzards, tornadoes and hurricanes, occur much less frequently. Due to global warming, the United States is today more than twice as likely to endure a devastating "dust bowl" scenario than during the Great Depression, researchers said Monday.
