The video in the link below includes ex Tory MP Sir John Redwood explaining in no uncertain words exactly why the net zero policy is foolish. If only more current Conservatives would speak out in this way.

“The contrived sense of accomplishment in history matching is spurious correlation for an infinitesimally small period of time. Using Exxon’s internal analysis of CO2 climate forcing is little more than a propaganda tool.”
“Exxon Knew” is a political-lawyer campaign focusing on certain internal company documents to make a case that the oil major knew that carbon dioxide (CO2) emissions were a future threat to human betterment.
Smoking gun? Hardly.
A half century later, the IPCC is still trying to update and figure out physical climate science. Exxon did not do a study on the benefits of CO2 or the offset of sulfur dioxide emissions. The concern way back then was Global Cooling, Peak Oil, and Peak Gas. And as the company knew, fossil fuels had no viable substitute, as in wind and solar.
This historical correction has been documented in many posts here at MasterResource, including:

It became my turn when I encountered this argument by Mark Burger on social media, He stated:
As opposed to fossil fuel industries war on hiding their impacts for decades? One example: “Exxon scientists predicted global warming with ‘shocking skill and accuracy,’ Harvard researchers say
My Rebuttal
To which I respond (expanded from my reply on social media):
To say that Exxon knew the truth back in the early 80s is a laughable fallacy. Effectively they built a primitive model that is characteristically similar to the erroneous modern climate models of today.
Fundamentally their work is based on the poorly understood climate sensitivity (ECS) derived from radiative convective models and GCM models. To their credit, they actually acknowledged the high degree of uncertainty in these estimations. Today, even Hausfather (2022 vs 2019) is beginning to understand the climate sensitivity (ECS) is too high. CMIP6 is running still even hotter than CMIP5 and using ECS of 3 to 5° C rather than ~ 1.2° C as highlighted in Nick Lewis’s 2022 study.CMIP6 should have been better because it incorporated solar particle forcing (Matthes et. al.) and as they incorporate more elements of natural forcing (an active area of research as we still do not have a predictive theory for climate), the effect is highlighting more underlying problems with the models.
However, Exxon investigators fell into the same trap that climate modelers of today where they build the models to history match temperatures and then wow, because they can create a model that appears to history match temperatures, they assume it is telling them something. Truth? Anyone can create a model to do this, but it would never mean the model is correct. While the models today are much more complex, they are based are based on a complex set of non-linear equations, and the understanding the various sources of nonlineararity is poor. This opens up wide degrees of uncertainty yet wide opportunity for tuning. Furthermore, natural forcing is undercharacterized and deemed inconsequential.
The contrived sense of accomplishment in history matching is spurious correlation for an infinitesimally small period of time. Using Exxon’s internal analysis of CO2 climate forcing is little more than a propaganda tool. Current climate models, much more sophisticated, face the same problem of unknown, false causality.

From CLIMATE DEPOT
ANN ARBOR, Mich. — The auto industry is big business in Michigan, and a major round of layoffs is revving the election into high gear for industry workers in the critical swing state — who blame the Biden-Harris administration’s heavy-handed electric-vehicle mandates for the painful job losses.
Stellantis, which manufactures Chrysler, Jeep and Dodge vehicles, announced last month it will lay off 2,450 workers at its Warren plant. While industry jobs in the state have been declining since 1990, Michigan autoworkers explained to The Post why Team Biden’s green-energy rules are at fault this time.
United Auto Workers member Isaiah Gordon, 24, works on hybrid batteries at Ford’s Rawsonville plant and said the forced transition to electric vehicles is damaging the industry.

Note, just because the Earth is 1.3°C warmer than Little Ice Age in 1850 and atmosphere holds more water vapor does NOT mean a particular weather event was caused by climate change. It’s not that simple.
