Excerpt:
Under Trump, climate denial has given way to something even more dangerous: climate erasure.

For 25 years, a group of the country’s top experts has been fastidiously tracking the ways that climate change threatens every part of the United States. Their findings informed the National Climate Assessments, a series of congressionally mandated reports released every four years that translated the science into accessible warnings for policymakers and the public. But that work came to a halt this spring when the Trump administration abruptly dismissed all 400 experts working on the next edition. Then, on June 30, all of the past reports vanished too, along with the federal website they lived on.

A lot of information about the changing climate has disappeared under President Donald Trump’s second term, but the erasure of the National Climate Assessments is “by far the biggest loss we’ve seen,” said Gretchen Gehrke, who monitors federal websites with the Environmental Data and Governance Initiative. The National Climate Assessments were one of the most approachable resources that broke down how climate change will affect the places people care about, she said. The reports were also used by a wide swath of stakeholders — policymakers, farmers, businesses — to guide their decisions about the future. While the reports have been archived elsewhere, they’re no longer as easy to access. And it’s unclear what, if anything, will happen to the report that was planned for 2027 or 2028, which already existed in draft form.

So why did the reports survive Trump’s first term, but not his second? You could view their disappearance in a few different ways, experts said — as a flex of executive power, an escalation in the culture war over climate change, or a strategic attempt to erase the scientific foundation for climate policy. “If you suppress information and data, then you don’t have the evidence you need to be able to create regulations, strengthen regulations, and even to combat the repeal of regulations,” Gehrke said. 

This isn’t climate denial in the traditional sense. The days of loudly debating the science have mostly given way to something quieter and more insidious: a campaign to withhold the raw information itself. “I don’t know if we’re living in climate denial anymore,” said Leah Aronowsky, a science historian at Columbia Climate School. “We have this new front of denial by erasure…”
