As my local KQED now ignorantly pushes, hurricane Beryl became more dangerous due to climate change. KQED is one of a thousand-plus stations supported by your tax money via the Corporation for Public Broadcasting. CPB receives federal funding from Congress and distributes the vast majority of funds to more than 1,500 locally managed public radio and television stations across the United States. They all broadcast the same bogus analyses that climate change makes hurricanes more deadly. Disturbingly those stations never report all the natural dynamics that make hurricanes more intense.

Rapid hurricane intensification has been observed for over a century. The director of the National Weather Service has reported, “Every Category 5 hurricane that hit this country in the last 100 years had only been a tropical storm 3 days [earlier].” So, what supplies that added energy to intensify those hurricanes?

Hurricanes intensify due to 1) warmer Sea Surface Temperatures (SST) 2) changes in wind shear, and 3) changes in barrier layer thickness. Sadly, barrier layer thickness is typically ignored but the most important. As reported in the article, “Why Hurricanes Intensify!”, a key to hurricane intensification is the location and thickness of ocean barrier layers.

Unfortunately, the media prefers to simply blame CO2 warming for intensification. However as observations reveal, the SST warming in the northern Atlantic has been driven by the Atlantic Multidecadal Oscillation (AMO) , which causes more warming in the north Atlantic but cooling in the south Atlantic. In contrast to claims that global warming is increasing the frequency and intensity of global hurricanes, observations show hurricane intensification is a function of regional dynamics. The southern Atlantic has rarely experienced a single hurricane during the satellite era. In contrast, the greatest occurrence of strong hurricanes has happened over the western Pacific Warm Pool.

Despite false hype that climate change is intensifying global hurricanes, for the first time in the satellite era (1966-onwards), the entire North Pacific (e.g., western North Pacific, central North Pacific, eastern North Pacific) has had no named storm (e.g., tropical storm or #hurricane) activity from June 1 – July 3.

According to the IPCC, the decade with the most Category 5 hurricanes is 2000–2009, with eight Category 5 hurricanes having occurred: Isabel (2003), Ivan (2004), Emily (2005), Katrina (2005), Rita (2005), Wilma (2005), Dean (2007), and Felix (2007). The previous decades with the most Category 5 hurricanes were the 1930s and 1960s, with six occurring between 1930 and 1939.

As the IPCC states, identifying past trends in TC [Tropical Cyclones] metrics remains a challenge due to the heterogeneous character of the historical instrumental data, which are known as ‘best-track’ data (Schreck et al., 2014). There is low confidence in most reported long-term (multi-decadal to centennial) trends in TC frequency- or intensity-based metrics due to changes in the technology used to collect the best-track data.

A subset of the best-track data corresponding to hurricanes that have directly impacted the USA since 1900 is considered to be reliable, and that shows no trend in the frequency of USA landfall events(Knutson et al., 2019).

A similarly reliable subset of the data representing TC landfall frequency over Australia shows a decreasing trend in Eastern Australia since the 1800s (Callaghan and Power, 2011), as well as in other parts of Australia since 1982 (Chand et al., 2019; Knutson et al., 2019). A paleoclimate proxy reconstruction shows that recent levels of TC interactions along parts of the Australian coastline are the lowest in the past 550–1500 years (Haig et al., 2014).

The ACE index integrates all the cyclone energy and the ACE index shows no trend driven by globa warming

Global warming has nothing to do with changes in hurricanes!
