From CNN's chief data analyst Harry Enten:
I mean, just look at these numbers. Okay, top issue in a midterm vote — you can list up to three issues. The economy, not surprisingly, comes in at number one at 54%. Immigration, 28%. Look at climate change — it’s tied for 14th, tied for 14th, all the way down here at 3%. Johnny, I’m not the greatest mathematician in the world, but I sure as heck know that 54% is a whole heck of a lot higher than 3%. So despite the climate being so warm in the month of July, the hottest month on record here in the United States of America, the voters, simply put, do not say that climate change is going to be an issue on which they vote in the midterm election.
And you can see this 3% here, and you can see in these slides right here: “Say climate change is a very big problem.” In 2016, it was 40%. It was 40%. Look where we are in 2026 — it’s 39%, it’s 39%. Now, Johnny B, you’re talking about change. Where the change we have seen is partisanship, right?<
And what we can see is Republicans, more so than anybody else, have been shifting away from the idea that climate change is a top issue for them. Take a look at this — the least important issue for Republicans, it’s just at 14% in terms of saying that climate change is a very big problem. So we’re seeing a large partisan split, but when it comes together, Democrats are going in one direction, Republicans are going in another direction. But when you put those two together, the bottom line is we’re only talking about two in five Americans, both now and 10 years ago, saying that climate change is a very big problem.
Maybe a few more towns burning down will convince them. Higher home insurance rates in Florida (if homeowners can get it at all). A few more records (this July was the warmest month ever recorded in the continental US). Or more thousands of deaths.
Relative to a 1951-1980 baseline, July's USA48 temperature anomaly is 1.81°C. Relative to 1901-2000 the anomaly is 2.34°C. [NOAA's USA48 data starts in 1895.]
This decade-to-date is 0.53°C warmer than the last decade-to-date. The 30-year linear trend is 0.31°C/decade (0.55°F/decade). The total (linear) warming since 1895 is 1.33°C (2.39°F).
