Many Americans celebrate Earth Day by planting trees, organizing a citywide trash pickup, or talking about the consequences of climate change and the ongoing threat it creates for our planet. But on Earth Day yesterday, all four Republican candidates for Senate in North Carolina used the opportunity to deny that climate change is real. TPM reports:

Fittingly, all four Republican candidates in the North Carolina Senate race were asked on Earth Day if they believed climate change is a proven fact. And all four candidates said "no."

The question was asked during a GOP primary debate on Tuesday night. The candidates, House Speaker Thom Tillis, Rev. Mark Harris, Dr. Greg Brannon, and nursing practitioner Heather Grant, in response to the question, said "no."

This is not the first time Republicans have denied the existence of climate change and it will likely not be the last. But the fact that all four candidates agreed underscores the GOP extremism in the North Carolina Senate race and serves as yet another example of a political party increasingly divorced from reality.
