It should also be really obvious that there are many ways to prevent these problems at the source. We can ramp up regulations on pollution to be much, much stricter than they are now, and give them real teeth. We can combat overseas pollution with sanctions and trade agreements. We can reject politicians who stymy these efforts, and sometimes even backpedal efforts by leaving the Paris Agreement and making a fuss. There are many avenues open to solving climate change problems that don't involve inventing global terraforming.
