1/13》Sen. Roberts was wrong.
Well, his first 36 seconds (apparently learnt from scientists) was correct.
But the rest, which he called "beyond the science," culminating in his claim that "humans do not affect the level of carbon dioxide in the atmosphere," is codswallop.
NET ZERO - This is the science they don’t want you to hear!
And it won’t be long before any science that deviates from the narrative is censored as dangerous ‘misinformation’
So before you’re not allowed to hear the truth get educated
2/13》Mankind currently adds about 5 ppmv/year of CO2 to the atmosphere.
Nature removes an average of about 2.5 ppmv/year of CO2 from the atmosphere.
Economic downturns, like the Covid-19 recession, reduce that 𝘀𝗹𝗶𝗴𝗵𝘁𝗹𝘆, as do CO2 emission reduction schemes…
4/13》The processes which remove CO2 from air (terrestrial "greening," dissolution into oceans, rock weathering, etc.) all accelerate sharply with increasing CO2 level. All the major removal processes are approximately linear over ranges of interest, so their sum is also linear.
5/13》That linear relation is simple: From historical measurements over the last 65 years we can determine that each 43 ppmv increase in average atmospheric CO2 concentration increases the summed rates of natural CO2 removals by about 1 ppmv.
6/13》That means that if CO2 emissions were to remain at their current rates, the atmospheric CO2 concentration would increase by only about (2.5 × 43) = 107 ppmv before plateauing.
9/13》Now we have enough information to determine what temperature change to expect if there are no changes in CO2 emission rates (nor changes in other GHG levels, nor changes in aerosol & particulate air pollution, nor changes in natural forcings).
10/13》"Practical climate sensitity," determined from comparing temperatures to GHG level changes (roughly (TCR+ECS)÷2) is at most about 1.5°C per doubling. 33% of that is 0.5°C.

12/13》So with no changes in CO2 emissions or other factors we should expect only about 0.6°C (1.1°F) of additional warming.
That's too tiny to be noticed even indoors! HVAC thermostats typically operate with 2-3°F hysteresis (dead band), and we don't notice the fluctuations.
