The Trump Administration's plan to dismantle the @ncar-ucar.bsky.social is senseless & dangerous.

It would weaken weather forecasting, climate research, & the science that keeps people safe.

We urge that this plan be abandoned.

"Without NCAR’s infrastructure + supercomputing abilities, many small colleges & universities wouldn’t be able to do research with the latest models. NCAR research influences every piece of weather & climate prediction in the US: air quality, droughts, hurricanes + more." - @carlonimbus.bsky.social

NCAR is quite literally our global mothership.

Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources.

Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.

Unbelievable.

The comment period for a sham “climate science” report commissioned by the DOE closed earlier this week, and the verdict is in: the scientific community has overwhelmingly and resoundingly rejected the report. UCS submitted comments on the report, and here are the four key points we made:

ucs.org Union of Concerned Scientists @ucs.org · Sep 2
The Trump Administration is using tactics straight out of the fossil fuel industry playbook to undermine climate science—but we won't let them get away with it.

Today, we're voicing our strong opposition to the deeply flawed, anti-science report commissioned by the DOE.

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report.
This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.

Example: refuting one sentence.
DOE CWG STATEMENT (second paragraph of section 2.1.1, page 3): “Piao et al. (2020) noted that greening was even observable in the Arctic.” COMMENT: This statement implies that the Arctic greening signal was caused by elevated CO2 , however that is not the scientific consensus. Piao et al. (2020) attribute the greening trend in the Arctic predominantly to growing season length driven by warmer temperatures (see also Y. Zhang et al., 2022). Piao et al. (2020) also note that this positive impact of increasing temperatures appears to have weakened over the past four decades, “suggesting a possible saturation of future greening in response to warmer temperature” (see also comment on greenness trends related to Section 2.1.1, first sentence of Page 4). It is also important to put Arctic greening more broadly into the context of the carbon cycle and other impacts. While above-ground plants may have displayed more leaf area over the past decades, rising temperatures also thaw permafrost and drive accelerated decomposition in highly carbon rich soils (Turetsky et al., 2020), a process which is expected to accelerate as climate continues to warm (Miner et al., 2022). Thus even with Arctic greening, high latitude terrestrial systems may become net carbon sources to the atmosphere, causing an amplifying feedback (Braghiere et al., 2023). Other risks to the Arctic linked to higher CO2 levels and rising temperatures are not mentioned in this report (Virkkala et al., 2025). The Arctic is warming at a rate of 2 to 3 times the global average, leading to thawing of permanently frozen soils (permafrost), with downstream impacts including loss of structural support for buildings and subsidence, threatening communities, roads, runways, and other assets across Alaska (Manos et al., 2025; University of Alaska Fairbanks Institute of Northern Engineering US Army Corps of Engineers Alaska District & Laboratory, 2019).
