Michael Bastasch of the Daily Caller reports on an open invitation to U.S. Rep. Alexandria Ocasio-Cortez.

Skeptics of global warming “catastrophe” have an extended an offer for Green New Deal champion New York Rep. Alexandria Ocasio-Cortez to come and debate them.

Retired statistics professor Dr. Caleb Rossiter offered a standing invitation for Ocasio-Cortez, and others who have attacked the CO2 Coalition, to come and debate climate science and energy policy.

Taking a page from his early anti-war activism days, Rossiter put a piece of paper with Ocasio-Cortez’s name, and the names of other “alarmists,” on an empty chair next to panelists during a Friday panel at this year’s Conservative Political Action Conference (CPAC).

Rossiter said anti-war activists would have empty chairs at events reserved for Defense Department officials who, though invited, would never show up. …

… Rossiter, who serves as the CO2 Coalition’s executive director, said the Democratic lawmakers’ intimidating letters inspired him to offer an open invitation to CO2 Coalition events.

The CO2 Coalition is often labeled as spreading “climate denial” by their opponents for arguing global warming will likely be beneficial because increased carbon dioxide levels stimulate plant and crop growth.

But the CO2 Coalition is made up of dozens of scientists and policy experts who reject the “carbon dioxide catastrophe” narrative as Rossiter called it Friday, but they don’t reject greenhouse gas theory.

Alongside Rossiter at Friday’s panel were Cato Institute climate scientist Patrick Michaels and Manhattan Institute economist Mark Mills, both of whom are CO2 Coalition members. Michaels criticized the “alarmist” climate change narrative, and Mills laid out his case for why sweeping plans, like Ocasio-Cortez’s Green New Deal, wouldn’t work.
