Adding CO2 in a high risk location and removing it somewhere else is a less meaningful offset the closer the location of addition gets to a crisis point.

This is causing global average temperatures to rise, and as ice melts will also lead to sea-level rise.  Both climate change and sea level rise will be harmful to humans on balance, and especially hurt people in low-lying areas and in areas that will get much less rainfall.  When someone chooses to burn fuel and release CO2 they are creating an externality, contributing, very slightly, towards a large harm.  By taxing emissions at a level approximating the social harm they cause we internalize this externality, that is we get the people burning the fuel to make a decision based on not just the benefit they get from burning the fuel but also the harm that the emissions will cause to others.  Funding things through taxing emissions is much better than other ways of raising the same money, because while most taxes are distortionary (preventing otherwise beneficial trades) emission taxes get people closer to how they would behave if they couldn't push the costs of their pollution off on others.", "timestamp": "1576948709"}, {"author": "Korz", "source_link": "https://www.lesswrong.com/posts/mFeGmtdLLaeHqyxuk#6MgfnDWqsrkxQcjR5", "anchor": "lw-6MgfnDWqsrkxQcjR5", "service": "lw", "text": "This argument does make sense and makes me wonder what other reasons there are for me to avoid flying if I accept that the impact of CO2 is solvable without excessive additional costs.
