The reality concerning global warming and the IPCC climate change “hypothesis,” made in 1990, “that our global warming is primarily due to CO2emissions” is clear; (1) All the meetings, messaging, and pleas over the last 33 years, to reduce CO2emissions have cost billions, generated fear and been totally unsuccessful. Annual CO2emissions continued to accelerate. They increased worldwide by more than 160%., (2) Multiyear periods of global temperature cooling and stability, documented from 1880, do not correlate with continuously rising CO2emissions and atmospheric CO2since then, (e.g., for 34 years from 1945-1979 the global temperatures was cooler than the 1944 temperature and CO2emissions from 1945-1979 quadrupled, from 4.2 to 19.6 billion tonnes/yr.)., (3) Hundreds of billions of added tonnes of CO2were emitted to the atmosphere since 1979, when global temperatures began to rise and, per the IPCC, CO2had taken primary control of global warming. However, all the CO2added to the atmosphere did not, in the last 24 years, produce an increase in global warming rate over the rate from 1976 to 1998, which led to the CO2culpability hypothesis. Rather, based on the NASA global land-ocean temperature index, the more recent, 1998 to 2022, global warming of 0.280C or 0.0120C/yr., is considerably less than the 1976 to 1998 global warming of 0.710C or 0.0320C/yr., that ushered in the climate change due to CO2fixation., (4) These actual data from 1945-2022 clearly show that natural climate variables, not CO2emissions, are responsible for producing the global temperature changes in the “Current Warm Period” interglacial., and (5) Unlike the rest of the world the US CO2emissions have declined since 1990. Yet US government and climate activists’ actions, policies, and urgings (e.g., -a ban on gas stoves) are being proposed and imposed on the US citizenry to halt “climate change” and “save the planet.” These actions are being carried out: (a) despite the fact that continued worldwide increase in CO2emissions render US CO2emission reduction inconsequential and (b) the reality is that CO2emissions have not and are not significantly affecting the planet’s warming. And, it is evident that the push in the US for CO2emission reduction programs, restrictions and policies are being invoked and exploited for political gain and ideological virtue signaling, as the data show they will have no substantive effect on global warming. America, we’re being deluded, gaslighted and exploited.

Harvard Gazette Jan, 12 2023. “Projections created internally by ExxonMobil starting in the late 1970s on the impact of fossil fuels on climate change were very accurate, even surpassing those of some academic and governmental scientists, according to an analysis published Thursday in Science by a team of Harvard-led researchers. Despite those forecasts, team leaders say, the multinational energy giant continued to sow doubt about the gathering crisis.
In “Assessing ExxonMobil’s Global Warming Projections,” researchers from Harvard and the Potsdam Institute for Climate Impact Research show for the first time the accuracy of previously unreported forecasts created by company scientists from 1977 through 2003. The Harvard team discovered that Exxon researchers created a series of remarkably reliable models and analyses projecting global warming from carbon dioxide emissions over the coming decades. Specifically, Exxon projected that fossil fuel emissions would lead to 0.20 degrees Celsius of global warming per decade, with a margin of error of 0.04 degrees — a trend that has been proven largely accurate.
The current debate about when Exxon knew about the impact on climate change carbon emissions began in 2015 following news reports of internal company documents describing the multinational’s early knowledge of climate science. Exxon disagreed with the reports, even providing a link to internal studies and memos from their own scientists and suggesting that interested parties should read them and make up their own minds.
“That’s exactly what we did,” said Supran, who is now at the University of Miami. Together, he and Oreskes spent a year researching those documents and in 2017 published a series of three papers analyzing Exxon’s 40-year history of climate communications. They were able to show there was a systematic discrepancy between what Exxon was saying internally and in academic circles versus what they were telling the public. “That led us to conclude that they had quantifiably misled the public, by essentially contributing quietly to climate science and yet loudly promoting doubt about that science,” said Supran.”
