No you are right if it was just a country's policy that could be reversed that would be one thing but we already hit 1.5C and even if stopped everything today it's going to be rough but we are not stopping everything today. We are going to accelerate for the next 4 years to make old rich people even richer. The climate doesn't stop on a dime if we stop at 3C it will coast on its own to 4C. Also I do help where I can to ease the suffering around me. I donate $300 a month to my local food bank it's not much but they tell me that's feeds 20 people. I am part of a Mutual Aid Network. I still help I just have switched my energy from trying to change things to just harm reduction. Kind of like human civilization is on hospice and I'm the nurse that is just giving them morphine.

Note I do this as a disabled veteran that needs a certain medicine in order to live. Once that med can't be made I become confined to my bed then die a little after.
