In fact Klotzbach’s plot above shows that there has even been a modest decline.
Pielke Jr. on how extreme weather is NOT getting worse:
‘Flood disasters are sharply down. U.S. floods not increasing either.’
‘Is U.S. drought getting worse? No.’
‘U.S. hurricane landfalls (& their strength) down by ~20% since 1900.’
‘Recent years have seen record low tornadoes.’
Professor Pielke Jr. also noted: “US hurricane landfalls (& their strength) down by ~20% since 1900” and provided this graph.

Tuesday marks a record 127 months since a major hurricane has made landfall in the continental United States, according to statistics compiled by the National Oceanic and Atmospheric Administration’s (NOAA) Hurricane Research Division, which keeps data on all the hurricanes that have struck the U.S. since 1851.
The current drought in major hurricane activity is a “rare event” that occurs only once every 177 years, according to a study published last year by researchers at the NASA Goddard Institute for Space Studies (GISS) entitled
The Frequency and Duration of U.S. Hurricane Droughts.

Obama has seen just four hurricanes make landfall on his watch, none of them classified by NOAA as major storms. Three were Category 1 storms (Irene in 2011; Isaac and Sandy in 2012) and just one was a Category 2 hurricane (Arthur in 2014).

Flashback 2014: PROF. ROGER PIELKE JR: TESTIMONY ON THE CURRENT STATE OF WEATHER EXTREMES: ‘It is misleading, and just plain incorrect, to claim that disasters associated with hurricanes, tornadoes, floods or droughts have increased on climate timescales either in the United States or globally’ —
Link to full testimony of Roger Pielke Jr. to Congress: ‘It is further incorrect to associate the increasing costs of disasters with the emission of greenhouse gases’ Globally, weather-related losses ($) have not increased since 1990 as a proportion of GDP (they have actually decreased by about 25%) and insured catastrophe losses have not increased as a proportion of GDP since 1960.
• Hurricanes have not increased in the US in frequency, intensity or normalized damage since at least 1900. The same holds for tropical cyclones globally since at least 1970 (when data allows for a global perspective).
