Common sense.
There is a way to reduce warming cheaply and relatively easily. And it doesn’t involve banning gas stoves, outlawing people’s cars, or decimating the fossil fuel industry. You just need to plant a trillion trees. There are innovative design projects in place allowing trees and shrubbery to be planted on and around buildings in urban areas, along with vast tracts of former forestland that should be restored. All of those plants will create shade, lowering the local temperature. They will simultaneously suck carbon dioxide out of the atmosphere and replace it with oxygen if you’re interested in that sort of thing. Sadly, trees do all of this on their own with no intervention from humans. That means they don’t make any money for people like John Kerry and his private jet-setting friends, so you’ll never hear them endorse it.
