Remember when people weren’t even sure climate change was real?

According to a new CBS News poll, 70 percent of Americans support the "U.S. taking steps to reduce climate change." That’s a big number—so big, in fact, that you’d think political action would be guaranteed, and that we’d be well on our way to halting global warming altogether.

Then how come Congress isn’t passing bills to do that right now? There are a lot of possible answers. That 70 percent finding doesn’t say anything about where climate action lies on respondents’ priorities list. It doesn’t shed light on what sort of actions and policies respondents would support. And perhaps most fundamentally, it doesn’t even define what climate change is.

This last part is particularly important, because it’s the only way to make sense of the CBS poll against others in the past year. Last August, Pew Research Center reported that only 46 percent of Americans believe the "Earth’s temperature is getting warmer mostly due to human activity." Another 26 percent said it was "mostly due to natural patterns," with "not sure" and "no solid evidence" receiving 14 percent each. That paints a very different picture of political support for climate policy, because if you think global warming is mostly due to natural patterns, you’re probably not going to support immediate curtailment of fossil fuels.

Pew also asked about prioritization. Only 37 percent said that "the president and Congress dealing with climate change should be a top priority." Another 34 percent said it should "be an important but lower priority"—which roughly adds up to that 70 percent support for climate action in CBS’s poll.

So why isn’t Congress putting the finishing touches on energy efficiency legislation as you read this? Instead, House Republicans seem inclined to declare war on home appliances that use too little energy.

Much like "do you believe in climate change?" before it, "do you support steps to reduce climate change?" or "do you think addressing climate change should be a priority?" may today be questions that have outlived their usefulness, obscuring more than they inform. Without identifying what those steps are, the questions are nearly meaningless. For while there are many policies that could be construed as "addressing climate change," those that don’t actually result in reduced emissions don’t fix the fundamental problem.

This conundrum is on full display in the conflicting assessments of the U.S.’s biggest climate legislation yet: the Inflation Reduction Act. By many measures, the IRA has been a smashing success, its tax incentives stimulating green investment all over the nation. Yet the law was tremendously difficult to pass, and probably only did so because the final text didn’t include any policies directly reducing, say, the combustion of fossil fuels. Oil and gas production has actually gone up dramatically since then. As TNR’s Kate Aronoff put it:

As a piece of green industrial policy, the principal aim of the IRA is to foster the development of strategic economic sectors so as to make the U.S. economy more competitive. Any emissions reductions it generates en route to that goal are largely incidental… businesses that take advantage of [the tax incentives]—including fossil fuel companies—are largely free to simply add lower-carbon lines of business onto their core, polluting business models.

You can see a similar problem in some "bipartisan" climate solutions being proposed, like one Time magazine published earlier this week for Earth Day: planting trees. It’s not that planting trees is bad. It’s often very good! But "planting a trillion trees," as former Speaker Kevin McCarthy proposed last year, would only prevent 0.15 degrees Celsius of warming while requiring 900 million hectares of land (land that may already be already storing carbon and supporting diversity in the form of prairies and wetlands, or that may be needed to produce food or renewable energy). And planting trees doesn’t actually transition the economy to more sustainable forms of energy. So it starts to look like a political sleight of hand to avoid the real need: reducing fossil fuel consumption and production (which McCarthy absolutely does not support).

While the CBS report didn’t mention it, its poll did ask people about specific policies: While 63 percent said they supported the Biden administration’s rebates and tax credits for energy efficiency, and 70 percent supported the reduction of toxic chemicals in drinking water, only 47 percent said they supported the administration reentering the U.S. into the Paris Climate Agreement, and 49 percent supported "spending on projects to reduce climate change." Tellingly, only 14 percent of respondents overall said they’d heard "a lot" about these policies, while 28 percent said "not much" and 22 percent said "nothing at all."

Climate scientist Katharine Hayhoe has famously argued over the past decade that "the most important thing you can do to fight climate change" is to "talk about it," which spreads awareness and may build political will for addressing it. But as awareness of climate change spreads, perhaps it’s time to tweak that prescription. The most important thing you can do to fight climate change may be to talk, specifically, about what policies and steps you support.

As the climate changes, cities will scramble to find trees that will survive

Trees are struggling to keep up with the warming world, Laura Hautala writes. Varieties that used to do well in certain areas aren’t doing well anymore, and that challenge will only increase with time. That may seem like a problem for forest conservationists, but it also presents a challenge for cities:

Urban arborists say planting for the future is urgently needed and could prevent a decline in leafy cover just when the world needs it most. Trees play a crucial role in keeping cities cool. A study published in 2022 found that a roughly 30 percent increase in the metropolitan canopy could prevent nearly 40 percent of heat-related deaths in Europe. The need is particularly acute in marginalized communities, where residents—often people of color—live among treeless expanses where temperatures can go much higher than in more affluent neighborhoods.… Urban botanists and other experts warn that cities are well behind where they should be to avoid overall tree loss. The full impact of climate change may be decades away, but oaks, maples, and other popular species can take 10 or more years to mature (and show they can tolerate a new climate), making the search for the right varieties for each region a frantic race against time.
