The moral case is really for the billions of people near the equator who cannot afford for temperatures to go up much more. It's too hot there already. We are making their countries insufferable to live in and we aren't compensating them for it. It's a travesty.
At least hundreds of millions, if not billions, can't afford airtight walls and a ceiling. Their homes are made of sheet metal and other scraps. They can buy a few panels for the family which rest on dirt to power their phones.
