If you really think that climate science is as robust as the knowledge of the fact that the earth is not flat, I suggest picking up a book and reading a little bit about it.
And contrary to all the propaganda, by being skeptic of all the doomsday prophecies, you'd be in the same camp with a joyful bunch of smart fellas: Freeman Dyson [1] (of Dyson sphere fame), John Clauser (2022 Nobel laureate in Physics) [2], Ivar Giaever (1973 Nobel laureate in Physics) [3], William Happer (Physics professor at Princeton) [4], Steve McIntyre [5], Alex Epstein [6], Peter Thiel [7], Bjorn Lomborg [8], John Christy [9]…
Nine contrarians, some of whom are funded by oil industry sponsored think tanks, others who have zero scientific qualifications (Peter Thiel B.A, Alex Epstein B.A, I mean, come on), don't stack up against the thousands of qualified climate scientists of the IPCC.
The science is pretty straightforward. CO2 absorbs infrared energy from the sun, raising its temperature (If you want to measure the amount of CO2 in an air sample, guess how we do that? Shine infrared light through it from one side and measure how much is missing on the other end). That heat is transmitted to the rest of the atmosphere through collisions with the other molecules, N2, O2 etc.
We use 100 million barrels of oil a day, approximately 70% of which is burned. About 22 million tonnes of coal and 11 million cubic meters of natural gas are also burned per day. Add in methane and you're looking at almost 140 million tonnes of CO2 equivalent entering the atmosphere every day. We've been building up to this level gradually over the last century or more. That CO2 that we're burning every day sits in the atmosphere anywhere between 20 to 200 years, absorbing heat from the sun every minute of every day.
