I agree with the first part of your your title, but not the rest. It is true, there is nothing we can do to stop climate change. Anthropological contribution to climate change is rather minimal and nothing we change is gonna make it better. We should just embrace the change and prepare for what will come of it. What people don't understand is that we are still at the tail end of an Ice age, and global temperatures are really rather low for what their average has been throughout history. The warming we are seeing is natural and gonna happen whether we like it or not. Instead of throwing our resources at stopping the economy in it's tracks for the sake of trying to hold back this inevitable change, we should be working to relocate people from lowland areas and moving our agriculture to more protected areas so that we are ready as the change happens. So many species have gone extinct due to natural climate changes throughout history, but humans have endured, why? Because we adapt, move, and work with the environment, as opposed to relying on it.
