FYI - I did aerospace engineering and we once had a NASA guy do a special lecture on planetary sciences. He'd done a research project where they tried to work out what it would take to make Mars habitable. Their conclusion was "its effectively impossible" planets simply don't take being forcibly changed. That was 30 years ago so I did an upgrade a while back regarding what we have now effectively managed to do. The surface area of the Earth is just over 510,000,000 km^2 and if you take just the first 1km of the earths atmosphere you pretty much have 1/2 a billion cubic kilometers of air. Its pretty straight forward to calculate how much energy it takes to heat that from say 20 to 21 deg. C and yeah its a big number with lots of zeros. Its just as easy to divide that number by the published energy release from something like the Hiroshima bomb. So its pretty easy to estimate how many Hiroshimas you need to let off to heat the planet up by a degree. Its a very scary number and makes no sense until you realise that up in the sky is a mega huge nuclear fusion reactor beaming energy at us and all you need to do is trap a bit extra for a century to start making some very serious changes. This is why Venus although only being just a little bit closer (in astronomical terms) is also massively hotter. Heads up if you do that calculation don't go trying to explain the number to average people. They can't comprehend the answer let alone understand what it means. 🤷‍♂️🤷‍♀️
