This week, investigative journalist Ian Wishart released a concerning report about NIWA being selective in its record of historical weather events. The downloadable report is available here: [investigatemagazine.co.nz](https://theoutdoorphonestore.com/175606/climate-of-fear/?sfw=pass1677624047&ref=goodoil.news).   
  
A summary of the document says:   

- Most of New Zealand’s biggest historic storms and cyclones are missing from NIWA’s Historic Weather Events Database (DATA GAPS>80%)
- The missing data is crucial for providing answers about whether extreme climate events are becoming more common (FREQUENCY)
- The missing data is crucial for journalists and researchers trying to compare the magnitude of modern climate events with those of the past (INTENSITY)
- Between 1868 and 1890 NZ was being hit yearly on average by storms similar to or more powerful than Cyclone Bola
- Five storms geographically bigger and with deeper barometric lows than Cyclone Gabrielle struck New Zealand between 1868 and 1890, revealing that what we call a 1-in-250yr event was actually closer to a 1-in-4yr event back then
- The late 1800s was a much colder, low carbon climate, raising fundamental questions about how extreme weather events play out in the real world vs computer modelling[climate-of-fear](https://theoutdoorphonestore.com/175606/climate-of-fear/?sfw=pass1677624047&ref=goodoil.news)

“And yet our supposedly supercharged cyclone \[Gabrielle\] at 963 hPa was a baby compared to the monsters that hit NZ every year in the latter quarter of the 19th century. Monsters as deep as 948 hPa,” Wishart [says](https://twitter.com/investigatemag/status/1631913616461946882?s=20&ref=goodoil.news).

Of course, it’s crickets from MSM:
