Impressive that he managed to find an angle on the whole Coronavirus that helps his argument, when most people are finding that the reduction in car traffic is improving air quality in cities around the world.
And the reduction in particle pollution is improving the efficiency of solar energy transfer to the earth's surface, thus increasing temperatures...
Global Dimming anyone?
The climate has always changed and will always change. There is negligible scientific doubt that increasing atmospheric CO2 is a forcing on global temperature.
All evidence based estimates of ECS (equilibrium climate sensivity) to the forcing of a doubling of CO2 in the atmosphere indicate a global temperature rise in the range 1-2°C.
All climate model projections of ECS which result in a threat to mankind require the use of the IPCC's RCP 8.5 scenario, which in turn estimates ECS at 4.9°C. RCP 8.5, designated 'business as usual' by the IPCC requires, for example, the coal industry to be 7 times bigger than 2019 by 2100. How likely do you think that is?
It's the deliberately wildly exaggerated consequences of a doubling of CO2 by climate activists that is the hoax. The removal of the prospect of the improvement in the quality of life of the poorest on the planet is their hypocrisy.
