Global warming: Are both sides wrong?

by Scott Sumner

“Many progressives view global warming as a looming catastrophe, justifying a major change in our lifestyle. Some conservatives regard global warming as a hoax. Most, however, acknowledge its reality, while arguing that economic models often show only a very modest hit to global GDP over the next century. (Large in dollar terms but quite small in percentage terms.) … I’d like to challenge the framing that both sides of the debate seem to have accepted, the view that addressing global warming requires major sacrifices. I suspect that the problem does requires major changes, but I see no reason to assume these changes would be sacrifices.” (06/21/22)
