Three points that should be noted:
1. The Wall Street Journal is almost completely against environmentalism and in particular, the concept of climate change. Just a little bias.
2. The author is not a climatologist, which you felt should be the yardstick by which those experts who comment on "global warming" are judged. His climatological work centred on agribusiness, and by his standards, "global warming" is a good thing, because it means a longer growing season.
3. The Cato Institute is an organization of pseudo-civil libertarians (think Ayn Rand) who have in the past, accepted large donations from the corporate sector, such as the tobacco industry and lobby and then have had their public statements mirror those of their benefactors. In addition, their "expertise" is limited, at best and is entirely based on the idea that humans and business should do whatever they want, with no market controls or legislation.
Some of their work is actually quite good. Other stuff, unfortunately, borders on fanaticism and lobbying-for-hire.
