COMMENT DEADLINE TODAY! If you are a US-based researcher, check what your prof. societies/orgs are saying about this rule. Even if you just pick one provision and write a paragraph w/ your experience, you can be part of collectively making a difference. (me: a former regulator). wapo.st/4w3O7vQ

Researchers worry a Trump rule could end U.S. scientific dominance

Research organizations warn a proposed rule for federal grants would upend the medical and technological advances that set U.S. science apart.

Co-developed with architects and engineers, NOAA recently launched the Typical Meteorological Year (TMY) data tool with both historical and future climate projections. Helping architects and engineers design for today’s and tomorrow’s climate = science -> action! www.ncei.noaa.gov/news/noaa-pr...

NOAA Provides Architects and Engineers Crucial Weather Data

On April 13 2026, NOAA’s National Centers for Environmental Information (NCEI) released the Typical Meteorological Year (TMY) product to the U.S. public.

I remain extremely proud of NCA5-- I'm proud of the process, the content, and the hundreds of people who volunteered their time and expertise over many years to make it happen. The NCA is a true reflection of gold standard science. Platinum even.

"The second Trump administration is taking its hostility to climate science to new levels...recently released government documents show how the administration is seeking to replace scientific facts with propaganda and disinformation," writes UCS's Rachel Cleetus.

My colleague @bobkopp.net has a nice thread rundown of the many problems and illegal actions of the Dept of Energy Climate Working Group report based on the emails that came out yesterday from @envdefensefund.bsky.social lawsuit: www.edf.org/media/newly-... I would just add a few things re NCA5 1/

Newly Disclosed Records Show Trump Administration’s Unlawful Actions Related to Secretly Formed “Climate Working Group”

The records are part of more than 68,000 pages of records obtained by EDF and the Union of Concerned Scientists as as the result of a lawsuit.

Today, the U.S. faces one billion+ dollar climate/weather disaster on average every 2w. That's a massive increase from one every 4m in the 1980s. This is 'global weirding' and people are taking notice! The government told NOAA to stop tracking these events: but @climatecentral.org is on the job.

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).

DOE climate report response form

We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me. We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.
