The principal problem with selling climate change mitigation to voters is that the benefits are uncertain, diffuse, and largely in the future, while the costs are felt today. Not many people, Americans included, are inspired by that bargain. So how does Biden sell the issue to the voters?
The impacts of climate change are already being felt in the form of property damage and soaring insurance costs. That is something Biden can tell the voters that will move them in the here and now. Trump, on the other hand, is completely indifferent to these costs.
