Liberals pundits and reporters took to Twitter to complain Fox News host Chris Wallace didn’t ask a question about global warming during the third presidential debate Wednesday night.

“It’s really disgraceful,” Paul Krugman tweeted, adding in another tweet: “Debate moderators have completely failed on the most important issue.”

So, four debates; four shout-outs by moderators to deficit scolds; not one question about climate change. It’s really disgraceful. — Paul Krugman (@paulkrugman) October 20, 2016

Environmentalists spent weeks pushing Wallace to ask presidential nominees Donald Trump and Hillary Clinton in the debate, but no such question was asked. The only time global warming came up in the debate was when Clinton talked about creating “clean energy” jobs.

“I want us to have the biggest jobs program since World War II, jobs in infrastructure and advanced manufacturing,” Clinton said.

“I think we can compete with high-wage countries, and I believe we should. New jobs and clean energy, not only to fight climate change, which is a serious problem, but to create new opportunities and new businesses,” she added.

That wasn’t good enough for pundits and activists concerned about global warming.

One reason Wallace likely avoided questions about global warming is that it doesn’t rank as a top tier issue for most voters. A February 2016 YouGov poll found only 9.2 percent of Americans rank global warming as their biggest concern. The biggest concern for Americans was global terrorism — 28 percent of Americans polled listed this as their top issue.
