Things that are not a problem right now: the national debt.

Things that are a problem right now: climate change.

Wallace says the debt hasn’t been discussed at the debates. That is really really not true. #coughclimatecough

Climate change enjoyed its 2 seconds of fame in the final debate https://t.co/92KKUbdbUT via @emmafmerchant

So that’s no climate questions through four debates, right?

Climate change never comes up unless HRC brings it up. Debate moderators have completely failed on the most important issue.

They should have talked about climate change. https://t.co/mLF6JmgbYx

I do think long-term debt is an issue, but the lack of climate change questions will look utterly insane to the future.

Here comes a question on the national debt written by Pete Peterson. God forbid we should talk about climate change

@HillaryClinton scores clean energy/climate mentions. Am betting significant sum Chris Wallace won't ask about climate. Takers?#ThirdDebate

— Dean Scott (@deantscott) October 20, 2016

Would it've killed Chris Wallace to have ended on a #climate question instead of national debt? Anyone? 3 debates, 0 climate questions.

sad climate change debate post, part 3. https://t.co/M9BZptl2ac

That's four straight debates without a single question on climate change. Good job, everyone. https://t.co/AcTYPhvxxb

So we're not going to talk about climate change during a presidential debate in Las Vegas. #debatenight

— Dan Savage (@fakedansavage) October 20, 2016

For the record, there was no talk about climate change in any of the debates

— Taegan Goddard (@politicalwire) October 20, 2016

After tonight’s debate, Trump will have escaped 3 debates without having to reveal that he does not believe in climate change. #Mediafail

— Touré (@Toure) October 20, 2016

And there we go. 4.5 hours of televised presidential debates without a single question on climate change #debatenight

— Oliver Milman (@olliemilman) October 20, 2016

So Chris Wallace finishes by ensuring there have been no questions about climate change or poverty this cycle. He is not a good moderator.

— Dylan Matthews (@dylanmatt) October 20, 2016

So four debates, and no discussion on climate change

— Nick Corasaniti (@NYTnickc) October 20, 2016

It's as if even asking about climate change is considered a liberal bias https://t.co/PI4ooTs9B2

— James Poniewozik (@poniewozik) October 20, 2016

Zero questions on climate change at any of the three debates. The closest was the question from...Ken Bone.

— Daniel Dale (@ddale8) October 20, 2016

No questions about the insane Chinese climate hoax Crooked Hillary is using as a pretext to crush the American coal industry?

— Matthew Yglesias (@mattyglesias) October 20, 2016

We're at the final question of the last debate and climate change has not come up in a serious way once. Criminal negligence. #debatenight

— Naomi Klein (@NaomiAKlein) October 20, 2016

We have now gone yet another entire presidential #debate season without a single climate question

— Brian L Kahn (@blkahn) October 20, 2016

There we go. Not a single question in three debates about climate change.

— Farhad Manjoo (@fmanjoo) October 20, 2016

So depressing, if not surprising, that in three debates, there was not one real question about climate change

— James Surowiecki (@JamesSurowiecki) October 20, 2016

Climate change question drought is precisely why we need an end to BIG-TV-NETWORK oligopoly on debates. #debatenight

— ErikWemple (@ErikWemple) October 20, 2016

And Wallace is wrong to say it hasn't come up; it was asked at vp debate. Climate change? Not so much. https://t.co/0MOQIV4K7I

— Joe Adalian (@TVMoJoe) October 20, 2016

Climate change? Anyone? Bueller? #debatenight

— Elizabeth Banks (@ElizabethBanks) October 20, 2016

No Climate Change discussion tonight. Sad.

— Bette Midler (@BetteMidler) October 20, 2016

Not a single question about climate change in all 3 debates. Sad. No, really - sad.

— Bill Maher (@billmaher) October 20, 2016

@DamienFahey called it-- not one question about climate change in any of these debates. That's bad. Real bad.
