Read here. Kevin Trenberth, a prominent IPCC "expert" deeply involved in the Climategate scandal, has long promulgated the IPCC prediction that CO2-induced global warming will cause an increase in tropical cyclones/hurricanes. Trenberth even doubles-down by stating that all modern severe weather events are the result of "unequivocal" global warming. Unfortunately for Trenberth and the IPCC, the overwhelming, unequivocally growing evidence documents well that cyclones/hurricanes have not increased as predicted.
First, as all know to be the case (click on adjacent image to enlarge), Trenberth is truth-challenged in public regarding the supposed "unequivocal" global warming claim (he sings a mightily different tune in private conversations). As the IPCC's gold-standard HadCRUT empirical evidence shows, accelerated global warming has disappeared over the last 15 years.
This evidence is irrefutable, yet Trenberth continues to claim global warming is "unequivocal" despite other climate alarmists giving up the ghost of AGW and are now producing research trying to explain the disappearance of global warming. (One would guess that this disturbing and consistent lack of stating the fundamental climate truth by Trenberth has to be a pathological disorder of some kind.)
Now in addition to the amazing disregard of actual global temperatures, a new study by Ying et al. determines that the empirical evidence proves that the China region has not experienced an increase of tropical cyclones over the last 50 years, which corroborates the vast majority of studies on this subject, globally. Thus, Ternberth's beliefs and predictions are again eviscerated by the cruel empirical scientific process - and the same holds true for the IPCC as well.
"The authors write that the Intergovernmental Panel on Climate Change (IPCC, 2001, 2007) has twice suggested that "precipitation and extreme winds associated with tropical cyclones may have become more intense." However, they note that this dual claim is "mainly based on numerical models,"...Working with tropical cyclone (TC) best track and related observational severe wind and precipitation datasets created by the Shanghai Typhoon Institute of the China Meteorological Administration...report that over the past half-century there have been no changes in the frequency of TC occurrence...they say that "during the past 50 years, there have been no significant trends in the days of TC...that "the seasonal rhythm of the TC influence on China also has not changed."...found that "the maximum sustained winds of TCs affecting the whole of China and all sub-regions have decreasing trends."...state that "the trends of extreme storm precipitation and 1-hour precipitation were all insignificant.""
