The evidence says: NO. Firmly NO.
Gasoline and jetfuel use have dropped off vertically during this China corona virus lockdown, and so have their prices, leading crashes in stock markets. But the generally accepted standard lab at Mauna Loa, which for many decades has been measuring net global CO2 atmospheric concentration, shows CO2 concentration is still increasing.
The UN IPCC and other organizations claim that human CO2 emissions, primarily from burning fossil fuels, are the largest contributor to the ongoing and increasing trend in global atmospheric CO2 concentration. But fossil fuel use is down 50% or more and CO2 is still increasing? How can this be?
This is very strong evidence that CO2 emissions from humans are insignificant, with trivial effect on atmospheric CO2 concentration and therefore insignificant to global warming and climate change. This is not the only instance. Professors Murry Salby and Jamal Munshi and others have previously demonstrated that the human contribution to the global net atmospheric concentration is too small to measure, and therefore human-produced CO2 cannot be significantly affecting global warming or climate. Those papers and references can be found on this blog.
Human-caused (anthropogenic) global warming by carbon emissions from use of fossil fuels is a gigantic fraud, far larger than the Enron fraud that sent Bernie Madoff to jail. Eventually, the climate fraudsters will also see justice.
