The climate is changing. That is something all of the current presidential candidates can agree on.

But that's about as far as the similarities go.

And in some key swing states and congressional races, the chasm between Republicans and Democrats on the issue could be enough to tip the scales come November 2024.

In the first GOP primary debate on Aug. 23, moderators struggled to get clear answers to the question "Do you believe human behavior is causing climate change?"

Businessman Vivek Ramaswamy has largely dismissed policies to address climate change altogether, calling the "climate change agenda" a "hoax." Other candidates believe the country should be taking action, but the issue takes a backseat to the economy and immigration.

There is overwhelming scientific consensus that climate change is driven by human activities, primarily burning fossil fuels. China currently produces the highest level of carbon emissions in the world, followed by the United States and India. But the U.S. is by far the largest historical contributor to climate change, and has significantly higher emissions per capita.

When Republicans do push for climate action, they say the focus should be pressuring China and India to clean up their acts. Most GOP platforms also call for increasing domestic energy production by expanding nuclear power and natural gas – while continuing to rely on fossil fuels. But they oppose the Biden-era regulations and subsidies to incentivize clean energy production and electric vehicle manufacturing.

Biden and his supporters have hit the campaign trail touting those investments made in the Inflation Reduction Act – which, despite its name, is actually a massive climate law that aims to encourage a transition to clean energy. Still, some Democratic-leaning voters say Biden has not done enough to curb emissions.

By and large, climate is not a driving force at the macro level of American elections. But it's an issue that is top of mind for young voters across party affiliations. People of color, who are often most affected by the impacts of climate change, and women also consistently say the issue should be a priority.

Whether or not those demographics turn out could make the difference in states where wins happen on the margins.

Where the candidates stand

For more than a decade, the GOP has largely rejected the science around climate change or resisted action to curb its effects. Some climate-minded Republicans see any acknowledgement of the issue from their presidential candidates as a sign of progress for the party.

By the numbers

80% of Democrats say addressing climate change should be given priority even at the risk of slowing the economy.

Meanwhile, 72% of Republicans say the economy should be given priority, even at the risk of ignoring climate change, according to an August NPR/PBS NewsHour/Marist poll.
