Here are all the current members of Congress who have doubted or denied climate change

• Sen. Dan Sullivan

"Alaska is on the front lines when it comes to changes in our climate, and with seven billion people on earth, humans will have an effect," Sullivan said in 2016. "However, despite what many climate change alarmists want us to believe, there is no general consensus on pinpointing the sole cause of global temperature trends."

In July 2018, Sullivan acknowledged some effects of climate change in Alaska, including erosion on roads and over-acidification of the water seen in fisheries, but said there were increased "opportunities in the Arctic."

"No doubt climate change is happening in Alaska...it's opening up opportunities in the Arctic, but it's also opening up significant challenges," Sullivan said on C-SPAN in 2018.

• Rep. Don Young

"Alaska is the focal point in the global warming debate. I do not challenge that climate change is occurring, but the central question awaiting an answer is to what extent man-made emissions are responsible for this change. Contrary to popular opinion, that question remains unanswered. Those who claim otherwise perpetrate a tremendous disservice to science and society, and I am shocked by the continued marginalization of any dissenters," Young said on the current iteration of his website.

Young also said in 2010, "I think this is the biggest scam since the Teapot Dome… Just be careful of the scam; Al Gore's biggest money-making machine in the world."

"I do not believe climate change is occurring," Biggs responded to a 2016 candidate survey from the Arizona Republic. "I do not think that humans have a significant impact on climate. The federal government should stop regulating and stomping on our economy and freedoms in the name of a discredited theory."

"There are credible scientists who say climate change exists; we aren't sure why. There are credible scientists who say that," Biggs said at a town hall the next year. "There are credible scientists who say it doesn't."

Cotton has also been a vocal critic of the Green New Deal, accusing the media of being "complicit in the Stalin-like or '1984' technique of disappearing" issues with an early draft of the bill and criticizing Democratic lawmakers for pushing what he called a "radical vision for humanity."

"They believe that Americans driving around in trucks on farms, or commuting from the suburbs where they can have a decent home into the city to work are a fundamental threat to the world, and they have to have the power and the control of those Americans' lives to implement their radical vision for humanity," Cotton said in February.

It's either held level or slightly decreased as our management has continued to increase. So apparently the climate change isn't affecting forest fires in my state. You would think even though it's a more moderate or temperate climate, if climate change was causing more fires we would see a lot more of them than what's in the baseline."
