The Nature Record Now it’s our turn to shape what comes next. A new project. A mission years in the making.

Ooh! Looks what available for public comment! Go Nature Record Team!
A draft of the first holistic assessment of nature in the U.S. is now open for feedback through May 30. Tell us what we’re missing, what you disagree with, and what changes you’re seeing in your community. naturerecord.org.

Ah mine broke a long time ago!

Trump Is Attacking Climate Science. Scientists Are Fighting Back. It’s easy, looking at the past year, to see the damage the administration has done. But researchers are also stepping up, trying to fill the gaps.

One year in the federal assault on climate science — a review and prospective

We’re all there. I particularly enjoyed the reference to Calvinball

Greenhouse gases endanger human health and welfare

I see that scrunchy :)

“Unambiguously correct”

A Secret Panel to Question Climate Science Was Unlawful, Judge Rules

Today we won.

A U.S. District Court ruled that the administration violated federal law when it secretly convened a group of climate contrarians to produce a thoroughly debunked report to overturn the Endangerment Finding.

The science still matters. We won't stop.

Thank you UCS and EDF!!!

NO!

Between the Old Bay and McRib posts, I'm starting to worry about you.

It’s a graph. But it’s also people. Real people who dedicated years of their lives to making the world a better place. Our colleagues, our neighbors, our friends.

U.S. Billion-Dollar Weather and Climate Disasters | Climate Central Explore U.S. billion-dollar weather and climate disasters since 1980, including total costs, trends, and impacts.

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.

Innovations in the climate assessment development process - Climatic Change Climate assessments have long been key scientific inputs that inform the development of productive and impactful climate policy in the United States and around the world. This introduction sets the stage for the suite of papers in the Topical Collection “Advancements in U.S. Climate Assessments.” Inspired and informed by the release of the Fifth National Climate Assessment, the papers within this issue document lessons learned over the past 30+ years and leverage the perspectives of previous assessment authors and staff to aid those interested in developing their own climate assessments. This paper reviews the evolution of climate assessments and the factors that make for useful, usable, and used scientific products to support societal choices. Evolving user needs over the last 30+ years also reflect a shift in demand towards more localized or more context-specific climate data that integrates social science information, tools, and frameworks. To meet these needs, we highlight three areas of potential opportunity and challenge for future assessments: continued and strengthened conversations between assessment developers across geographic scale to share innovations and lessons learned in the development process; working with knowledge holders in under-represented areas of expertise to alter assessment governance and guidelines to better incorporate diverse perspectives; and seizing opportunities for using innovative communication and engagement mediums.

One more paper in this series- the introductory paper was published yesterday amid the shutdown. Innovations in the climate assessment development process discusses the value of scientific assessments and how to keep them evolving to meet evolving user needs.

📢 Submissions are now open for the U.S. Climate Collection, a joint @theAGU + @ametsoc initiative.

This special collection will publish U.S.-focused climate assessment science that’s free to read, ensuring rigorous, accessible science informs decisions for years to come.

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).

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.
