I understand that GHGs cause warming but I'm against any costly actions that would try to mitigate their release as I don't see much harm in having more CO2. Mesozoic Earth had huge amounts of CO2 in the atmosphere and that didn't prevent life from thriving. Maybe it's way cheaper to just build walls to bar the sea level rise than to try limit fossil fuel use. Maybe corals don't die from acidification if they survived 10-times bigger CO2 levels in ancient times. Maybe it would be fun to have Antarctica ice free and warm again.
