75 years to work on a solution to a possible problem? I rate humanity’s chances. But Europe is responsible for a third of cumulative emissions. Once they undo that bit it should be okay. Negative emissions for 75 years will be hard but they can perhaps undo the damage they’ve done to the Earth.
It is a global challenge. Climate change is caused by rich people in developed countries (the average Indian person causes very low co2 emissions). There are some good initiatives to mitigate climate change, but so far, it is too little, too late. The US taking a back seat does not help either.
