  1. They are not being taken seriously because there is no climate crisis.

  2. Mostly dangerous drivel. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis. This video is anti-humanist.
