The 4 Notable Climate Moments from the First Republican Debate

Climate change was a major topic.

If we learned anything new from the first Republican presidential debate in Milwaukee on Wednesday night, it was not what anyone planned to do about climate change. The candidates failed to expand on their already scant or nonexistent platforms. Almost all of them failed to acknowledge that climate change was caused by humans.

But what was notable was the fact that the issue has finally earned a more prominent spot on the debate stage. Four years ago, activists railed against Democratic primary debate moderators for not asking any questions about climate change until the second hour of the program. The Fox News hosts got to the issue in about 20 minutes.

Below we’ve recapped what happened next, and the other most remarkable moments of the night for global warming, decarbonization, and energy.

Doug Burgum Comes Out Swinging Against Biden’s Climate Law

North Dakota Governor Doug Burgum, making his first comments in the debate, used a prompt to discuss the economy as a chance to rail against President Biden's historic climate law, the Inflation Reduction Act.

“The economy, energy, and national security are all tied together. We’ve got a plan, the $1.2 trillion of Green New Deal spending in the ‘Inflation Creation Act,’ that’s subsidizing China,” Burgum said. His primarily claim: That IRA subsidies will benefit Chinese battery and renewable manufacturers.

“If we’re going to stop buying oil from the Middle East and start buying batteries from China, we’re going to trade OPEC for Sinopec.”

The IRA, outside of the U.S., has come under fire for its stringent domestic production requirements for electric vehicles and includes domestic content bonuses. Will Kubzansky

The Republican Candidates Are Asked If They Believe Climate Change Is Caused By Humans

It only took 20 minutes for the Republican debate’s big climate change question to be asked.

Moderator Bret Baier chronicled the summer’s disasters, mentioning missing people in Maui, the rarity of a tropical storm in California, and the overheated ocean in Florida. Then Fox News played a clip from a young conservative.

Alexander Diaz, a student at the Catholic University of America on behalf of the conservative group Young America’s Foundation, noted the importance of climate change to young voters, teeing up Fox News’ Martha MacCallum to ask a simple question: “We want to start on this with a show of hands. Do you believe … human behavior is causing climate change? Raise your hand if you do.”

No candidates had raised their hand — although former Arkansas Gov. Asa Hutchinson seemed to be inching his hand up — when Ron DeSantis interrupted to say: “We’re not schoolchildren, let’s have the debate.” Will Kubzansky and Emily Pontecorvo

​Vivek Ramaswamy Calls the Climate Change ‘Agenda’ a ‘Hoax’ to Boos

Vivek Ramaswamy initially introduced himself to the American people on Wednesday night as a “skinny guy with a funny last name” — but perhaps his name was more aptly made, at least with many young conservatives, by calling “the climate change agenda … a hoax.”

Ramaswamy, a biotech entrepreneur running for his first political office, has previously claimed he’s not a “climate denier,” but also played coy, saying global warming will not be “entirely bad.” It was also not the first time he’s attacked what he calls “the climate cult in America.” In a video shared by his Twitter account this spring, Ramaswamy slammed climate activists for allegedly saying “that you have to abandon carbon emissions at all costs if you live in the United States.” He added, “It’s a cult that says … ‘We’re against nuclear energy’ … because nuclear energy might be too good at solving the alleged clean energy problem, which means they couldn’t use the climate as an excuse to advance a very different agenda.” Nuclear energy has historically been something of a bogeyman for environmentalists, who fear waste and meltdowns, but the nuclear power industry is also receiving billions of dollars from Biden’s two biggest pieces of legislation, the Inflation Reduction Act and the Bipartisan Infrastructure Law.

Wednesday’s “hoax” comment specifically came in reaction to the Fox News moderators trying to push the candidates into a yes-or-no answer about whether humans are responsible for climate change. Notably, no one immediately raised their hand. An overwhelming consensus of scientists — 99.9% of them, The Guardian found — say climate change is caused by mankind.

Ramaswamy’s answer was clearly an attempt to align his candidacy with former President Trump, who has called climate change "a hoax," “a total hoax,” “an expensive hoax,” and “a total, and very expensive, hoax.” Somewhat surprisingly, Ramaswamy's quip was met by audience boos — as well as interruptions from other candidates, who took issue with him calling himself the “only person on the stage who wasn’t bought and paid for.”

Earlier in the debate, a number of candidates had tip-toed around the possibility of “open[ing] up … energy production,” though Ramaswamy — who’s been said to be gunning to be “Republicans’ next Trump” — was characteristically blunt on that point, as well. “This isn’t that complicated, guys,” the 38-year-old chided his peers. “Unlock American energy. Drill. Frack. Burn coal. Embrace nuclear.” Jeva Lange

Nikki Haley: ‘Is Climate Change Real? Yes, It Is.’

When moderator Martha MacCallum asked the candidates to raise their hand if they believe that human behavior is causing climate change, Florida Governor Ron DeSantis took issue with the question.

“We’re not schoolchildren,” DeSantis immediately snapped back before anyone had put a hand in the air. “Let’s have the debate.” But instead of having the debate, he pivoted to bashing President Biden and showing off his extreme weather bonafides. “Biden was on the beach while those people were suffering,” he said, referencing the president’s response to the wildfires in Maui. “As someone who’s handled disasters in Florida, you gotta be activated.”

From there, the moment descended into chaos. Vivek Ramaswamy interrupted to say the “climate change agenda” was a “hoax.” Christie jumped in to toss insults at Ramaswamy.

The only candidate who managed to get a word in about their stance on the issue was Nikki Haley. ”We care about clean air and clean water but there’s a right way to do it,“ she said. “First of all, is climate change real? Yes it is.”

Haley's sole proposal was to push China and India to cut their emissions. She accused Biden of putting money in China’s pocket by subsidizing electric vehicles, and said the subsidies are “not working.” However, car makers have responded to the Inflation Reduction Act’s subsidies by investing millions in domestic manufacturing and domestic supply chains.

At the end, President Biden chimed in on Twitter with the last word. —Emily Pontecorvo

Impulse Labs debuted its much anticipated induction stove at the Consumer Electronics Show in Las Vegas this week. Coming to grips with this high-tech culinary wonder is a little bit like that meme of an expanding brain.

At first glance, the Impulse Cooktop is just a sexy-looking, $5,999 appliance: sleek black glass, burners that resemble a DJ turntable, knobs that add a satisfying analog touch to an otherwise fully digital interface.

Almost a third of global container traffic goes through the Suez Canal, and around 8% of the world’s oil and gas. Because of its pivotal location between the Indian Ocean and the Mediterranean, the Suez Canal — and thus the Red Sea, which feeds into the canal — connects the huge flow of goods and commodities from the Middle East and Asia to Europe.

On Thursday, conflict in the Red Sea and its surrounding waterways reached a new pitch, with United States and allied forces striking several targets in Yemen as a response to weeks of attacks on shipping and naval assets in the area. The Houthis, a rebel group backed by Iran that controls large portions of the country, including the capital, have justified their attack as a response to Israeli strikes in the Gaza Strip.

I Own an EV But Won’t Rent One on Vacation. Here’s Why.

Hertz backtracking on EV rentals is not a surprise.

A year ago, before a vacation to see the eruption of the Hawaiian volcano Kīlauea, I found myself scrolling through my rental car options. A few users on the car-sharing service Turo offered up their Tesla Model 3s, and I was tempted by the idea of driving electric on holiday just as I would at home. One problem: There are no superchargers on the Big Island. I opted instead for a dependable, decade-old Hyundai Sonata — one that cost half as much per day.

An electric rental car is an easier sell in a big city with plenty of fast chargers. Even so, it appears that Americans at large are making the same choice that I did. Rental car giant Hertz made a big splash by adding Teslas to its fleet in 2021 and using NFL legend Tom Brady to advertise them. Now, instead of scaling up to 25% EV by this year as it had once planned, Hertz says it will sell off a third of its EVs because of weak demand and higher costs. The company plans to use the money to shift back toward more gasoline-powered cars.
