Nova Scotia gets boondoggled on climate

RE: Report outlines climate change risks to Nova Scotia. A CP story published in the Hamilton Spectator 6 Dec 22.

The Nova Scotia government got fleeced by the report on the alleged impacts of climate change on the province.  Hopefully, the government isn’t deluded into thinking that Nova Scotia can halt climate change by its own heroism, and instead uses the report’s fearmongering to justify hardening infrastructure.

The authors couldn’t have done so much as a comprehensive literature review.  The forecasts of 4.5℃ temperature rise comes from RCP8.5, the most extreme climate model that scientists don’t take seriously, but is the one used by policy makers to scare the public into granting them more power.  The unrealistic RCP8.5 model requires over 1000 ppm CO2 in the atmosphere to achieve that temperature rise.  The realistic models predict between 460 and 580 ppm by 2100.

The forecast of a one metre rise in sea level is far higher than the IPCC forecast of between six inches and a foot rise by 2100.  The prediction of a 5.1℃ rise in ocean temperature won’t be caused by climate but on the Atlantic Multidecadal Oscillation phenomenon, the Atlantic Ocean’s version of El Nino.  The Atlantic Ocean – shockingly - will control Nova Scotia’s climate, not CO2 levels!

The business of storms like Fiona becoming stronger and more frequent requires amnesia to accept.  Atlantic hurricanes have been decreasing in number since the 1950s, and 2022 was a year of low activity.  Responsible meteorologists dismiss storm intensity as a climate phenomenon.

Nova Scotia’s risks are from money wasted on climate change, not climate change itself.

I wrote in my Oct 24^th 2022 piece, “Paris Accord Rests on Quicksand” the following concerning the RCP8.5 model:

“Nobody knows what the CO2 concentration will be in the year 2100.  I’ll test a couple scenarios to illustrate the nonsense.  The RCP8.5 model (Representative Concentration Pathway) forecasts 1000 ppm CO2 in 2100, producing a temperature rise of 4.3℃ and a “radiative forcing” (i.e. the greenhouse effect of that CO2) of 8.5 W/m².  But for 8.5 W/m² of additional forcing to increase temperature by 4.3℃, it requires the “global average temperature” to be 204K, by the Stefan-Boltzmann law.  That’s -69℃!”
