And then there were six...

almost 4 years ago

At the high point of the campaign over the summer, 17 candidates sought the Republican nomination for the presidency. With 265 days until the general election, that number now sits at six.

While half a dozen candidates is more manageable than 17, it's still a lot to remember when comparing and contrasting the positions of the one sitting governor, one former governor, two U.S. senators, one surgeon and one celebrity/real estate mogul who remain thick in the race. No wonder President Obama exaggerated when he said that none of the GOP candidates supports action on climate change.

As a refresher, here is where the six remaining presidential hopefuls stand when it comes to addressing climate change.

Dr. Ben Carson:

Climate "would not be the overarching driver" of a Carson administration, but he supports clean energy development. "We are blessed with tremendous energy in this nation and we need to be talking about new sources of energy," Carson has said. He opposes the Clean Power Plan and the "politicization of the environment."

Donald Trump:

Trump has repeatedly trumpeted his belief that climate change is nothing but changes in weather patterns. "It'll go up. It'll get a little cooler. It'll get a little warmer like it always has for millions of years. It'll get cooler. It'll get warmer. It's called weather," Trump has said. "We are going to work very, very hard on clean air and clean water. Those are all very important things. But climate change is not a priority."

Gov. Jeb Bush:

"Global warming is real, the climate is changing," Bush has said. "Man has had some impact on that." The former Florida governor believes the federal government's role is to "invest in the long term research and development, to find the next generation of renewable energy, but do it in a way that it doesn't increase costs." According to Bush, we should not "hollow out our industrial core to deal with" climate change.

Gov. John Kasich:

The current Ohio governor believes "we should be good stewards" of the environment and acknowledges that, "man impacts climate change."

"I'm a believer in renewables," Kasich had said. "I believe in the whole series of energy resources."

Sen. Marco Rubio:

While the junior senator from Florida often says, "the climate has always been changing," he also has come out strong for positioning American leadership on energy. "Let's lead the world in energy efficiency, but let's lead it through technological advances. I support leading the world in solar and wind and biofuels and in renewables. But I think we would be reckless and irresponsible not to fully utilize our natural gas, which is a clean fuel, and our oil too."

"I believe the American innovator will continue —without government interference— to do what it's doing now, which is to make us more energy efficient.

Sen. Ted Cruz:

Sen. Cruz is the most passionate climate denier of the remaining candidates, frequently questioning the validity of the science and the intentions of the scientists. "I understand there are scientists with political agendas," Cruz has said. "They don't get to own the data and evidence."

"Climate change is the perfect pseudo-scientific theory because it can never ever ever be disproven. If it gets hotter or older, wetter or dryer, the climate has always changed since the beginning of time and it will continue to change until the end of time," Cruz told New Hampshire voters prior to their first-in-the-nation primary.
