  Responding to new evidence is a feature of science, not a bug.

  Acid rain was an enormous problem, and is no longer because a large number of countries passed emissions regulations to curb emissions that caused it. Places like London used to have so much air pollution, going outside on a rainy day was hazardous to your health because the fog was toxic. The hole in the ozone layer is repaired because a large number of countries passed regulations prohibiting many uses of ozone-depleting substances, and consumers voted with their wallets as well. Unfortunately, we're not seeing anywhere near the commitment required to slash CO2 emissions, and a huge amount of damage is already done. It's not just climate change, but in the last fifty years, something like 2/3rds of wildlife has disappeared. In barely one generation we've wiped out two thirds of wildlife. That is mind boggling and if it doesn't count as a mass extinction, I don't know what does.

    Had consumers voted with their wallets for banning Freon? I don't know. Isn't it just a successful of developing alternatives and regulation? Maybe some consumers voted with their wallets for fuel economy car (thus lower CO2 emissions)

  We’re above 1 degree C and heading towards 1.5 very quickly, with rising methane levels from multiple sources. This isn’t the ozone hole. I wish it was.
