The U.S. National Climate Assessment (NCA) has long been touted as a cornerstone of the federal government’s climate agenda, a hefty tome meant to guide policy and inform the public about the perils of a warming world. But according to Patrick Brown, a climate scientist at the Breakthrough Institute, the NCA is less a beacon of scientific rigor and more a megaphone for partisan alarmism. In a recent article for The Breakthrough Journal (Spring 2024, No. 20), Brown lays out five practical recommendations to overhaul the NCA, aiming to make it a tool for genuine understanding rather than a cudgel for political mobilization. For our readers, his critique hits familiar notes—exposing the biases and hype baked into the climate establishment’s flagship report—while offering a path toward something more credible.
Brown’s starting point is a simple truth: the NCA, as it stands, is a one-sided affair. Released every few years under the auspices of the U.S. Global Change Research Program, it’s a document that reflects the priorities of whoever’s in power—lately, that’s been Democrats with a taste for apocalyptic rhetoric. But with a new administration on the horizon and a growing chorus of skeptics questioning the climate orthodoxy, Brown’s ideas couldn’t come at a better time. Here’s a rundown of his five fixes, and why they matter to anyone tired of being fed a steady diet of climate doom.
1. Include Exposure and Vulnerability, Not Just Physical Hazards
The NCA loves to spotlight “climate hazards”—floods, heatwaves, wildfires—as if they’re solely the spawn of rising CO2 levels. Brown calls this out as myopic. A real assessment of risk doesn’t just tally up weather events; it factors in exposure (how many people or assets are in harm’s way) and vulnerability (how well they can cope). Think about it: a hurricane hitting a sparsely populated coast in 1900 isn’t the same as one slamming into Miami today. Population growth, urban sprawl, and shoddy infrastructure often drive disaster costs far more than a few degrees of warming. By ignoring these, the NCA inflates climate’s role and dodges the messy reality of human decisions.
For skeptics, this is a no-brainer—stop blaming the atmosphere for bad zoning laws.
2. Analyze Total Risk, Not Just “Additional” Risk from Climate Change
Here’s where the NCA’s tunnel vision gets absurd. It fixates on the “additional” risk tacked on by climate change, as if the baseline risk from nature’s tantrums doesn’t matter. Brown gives an example: if heat-related deaths are dropping overall (thanks to air conditioning and better healthcare), but climate change nudges them up slightly, the NCA screams about the uptick while burying the bigger story of progress. This cherry-picking fuels the narrative that every problem is a climate problem, even when the data says otherwise. Readers here know the game—hype the delta, hide the trend. Brown wants the NCA to show the full picture: total risk, not just the climate boogeyman.
3. Address Publication Bias Head-On
The NCA leans heavily on peer-reviewed studies, which sounds great until you realize the academic machine churns out papers skewed toward dramatic findings. Brown points to “publication bias”—the tendency for journals to favor studies showing big, scary climate impacts over those finding little or nothing. A paper saying “warming might not hurt corn yields” doesn’t get the same love as one predicting famines. This distorts the NCA’s conclusions, making climate change look like a relentless juggernaut. Brown’s fix? Force the NCA to wrestle with this bias explicitly—maybe even seek out the ignored studies. For those of us who’ve long suspected the science is cooked to fit the narrative, this is a welcome jab at the ivory tower.
4. Focus on Description, Not Mobilization
The NCA isn’t shy about its agenda—it’s less a report and more a call to arms, dripping with urgency to “act now” on emissions. Brown argues this activist slant undermines its credibility. Science should describe what is, not preach what we ought to do. When the NCA doubles as a policy cheerleader, it alienates half the country—especially those who see climate action as a Trojan horse for bigger government or economic upheaval. Brown wants it to stick to facts: what’s happening, how certain are we, and what’s the range of outcomes? No rallying cries, no guilt trips. It’s a refreshing nod to objectivity in a debate drowning in propaganda.
5. Establish a “Red Team” Review Process
Perhaps Brown’s boldest idea is a “red team” review—a formal challenge to the NCA’s conclusions by an independent group of experts. Think of it as a scientific audit, poking holes in assumptions and testing the robustness of claims. The climate establishment hates this concept (remember the backlash to Scott Pruitt’s EPA proposal?), but it’s hard to argue against if you value transparency. A red team could expose weak spots—like overhyped models or dodgy attribution—and force the NCA to justify itself. For skeptics, this is the holy grail: a chance to break the echo chamber and let dissenting voices breathe.
Why It Matters
Brown’s reforms aren’t about doubting climate change, as he’s a believer, perhaps a lukewarmer, but about making the NCA a document both sides can trust. Right now, it’s a partisan football—kicked around by progressives when they’re in charge, ignored or dismantled by conservatives when the pendulum swings. With Trump back in the White House and Doge eyeing the budget axe, the NCA’s future is shaky. Brown’s vision might save it from irrelevance or deletion by grounding it in reality over ideology.
This critique aligns with what we’ve said for years: the climate narrative is oversold, oversimplified, and over politicized. Brown’s not tossing the NCA out—he’s trying to salvage it from its own excesses. Whether the climate elite will listen is another story. They’ve got a lot invested in the doom train—careers, grants, moral superiority. But if the NCA keeps peddling half-truths, it’ll only deepen the divide between the alarmists and the rest of us who just want straight answers.

I fully agree. The NCA is a national disgrace, an ‘official’ periodic US Gov climate propaganda piece cooked up in a collaboration by no less than 13 named US government agencies. As a sixth recommendation, I would apply criminal RICO with all 13 as named defendants racketeering to defraud the US into further ‘climate science’ funding for themselves.
In essay ‘Credibility Conundrums’ in ebook Blowing Smoke, I analyzed all six of the ‘climate catastrophe’ examples featured in 2014 NCA chapter 1, “Our Changing Climate” (subtext, ‘for the worse’). ALL were either blatantly false, or artificially contrived. ALL 6!
“The NCA is a national disgrace, an ‘official’ periodic US Gov climate propaganda piece cooked up in a collaboration by no less than 13 named US government agencies.”
Rud,
Am I to understand then that the heads of those agencies are the only ones in govt who decide which scientists are to produce the NCA report? Does the president not have any say in who produces the report?
I would think that if Trump is draining the swamp, he would replace the climate alarmist leftists in these agencies with individuals who can be trusted to appoint unbiased scientists for the production of the NCA. I don’t know, but perhaps this is something he has been overlooking.
Just my two cents worth.
Got some possible good news, CD. Just my own two cents.
The 4th NCA was in 2014 under Obama. The one analyzed in my book.
The most recent (5th) was in 2023 under Biden.
Now I expect 47 will cause a 6th NCA to be produced by YE 2028. THAT will be something. Somehow, I don’t think NCA should be a priority for 47 in month 1. We already got big beautiful USAID, NIH ‘admin OH’, and EPA ‘gold bars to Stacy Owen’s’ scalps in just 4 weeks. Even Geronimo Apaches would consider that a good one month Coup Scalp count.
I predict that a 6th NSA under Trump will be railed against and called “wrong” and biased because it was, well, Trumps.
But the railers will ignore any hint of bias in Obama’s and Brandon’s.
The US Global Change Program, USGCRP is the US deep state version of the UN Intergovernmental Panel on Climate Change (IPCC). When it was established by congress in 1990 it was told to assess both natural and human caused climate change. Instead, it has copied the IPCC and only considered human caused climate change. It is now a five billion dollar slush fund for climate modelers and climate activists.
The climate assessment report required by Congress can be summarized in a single paragraph:
At present the average annual increase in atmospheric CO2 concentration is near 2.5 parts per million (ppm) per year. This produces an increase in the emission downward longwave IR (LWIR) radiation from the lower troposphere to the surface of approximately 40 milliwatts per square meter per year (40 mW m-2 yr-1). It is impossible for this small increase LWIR energy to produce a measurable increase in surface temperature. Nor can it cause any change in the frequency or intensity of ‘extreme weather events’.
The 5th US Climate Assessment Report, NCA5 is a pack of lies. The climate fraud is contained in NCA5 Figures 1.5, 3.1, 3.2 and 3.3. I discussed this in the recent Tom Nelson podcast # 271. At present there are 15 different government agencies that are required to be part of USGCRP. The global warming and extreme weather nonsense contained in NCA5 has been taken from the Sixth IPCC Climate Assessment Report. Does anyone associated with the USGCRP understand anything about climate physics? Are they all grifters and rent seekers?
DOGE should audit the USGCRP, recover the money and shut it down.

Can’t shut it down if it was established by Congress. Need to get them onboard to cancel it.
But it can be gutted so it can’t serve any useful function to the deep state.
“A real assessment of risk doesn’t just tally up weather events; it factors in exposure (how many people or assets are in harm’s way) and vulnerability (how well they can cope). “
Maybe. But the NCA isn’t a risk assessmnt. It is a climate assessment. Climate scientists aren’t responsible for zoning laws. They describe how climate change will affect the world as it is.
No, Nick, the NCA’s describe how some fantasized Climate Change (TM) will affect some fantasy world as the authors imagine it.
Yep, the NCA is based on fantasy… It is a work of mal-science fiction.
Maybe we need to suggest who should write the next NCA.
Anthony, Linnea, Mark Morano, Will Happer, Tom Shula, Roy Clark, Willis…..
… are just some suggestions. 😉
Base it on actual science, rather than fantasies…
Surely we could find a good editor, CR 😉
“They describe how they surmise climate change will affect the world as it is.”
Fixed it for ya, matey 🙂
“They describe how climate change will affect the world as it is.”
There’s no possible way anyone knows that.
Describing how climate change will affect the world, is risk assessment.

There you go again.
-Ronald Reagan to Jimmy Carter, 1980 election debate.
“They describe how climate change will affect the world as it is.”
Anyone making such a statement has chosen to be blind to the incompetence of climate models to compute what they purport.
There is no real evidence that “the climate”, (whatever that is), is changing in any way that is detrimental to society.
Anyone that thinks they can prophesise what “the climate” will do and what effect that would have on society, is talking through their hat… delusional !
Climate models are basically just meaningless pre-designated computer games.
The longer we can keep the current interglacial period going, the better. If more CO2 in the atmosphere is the key to keep the planet warm, then so be it. It’s a good outcome compared to the ice-covered alternative.
That was what the father of greenhouse, Arrhenius thought, or hoped. But then he realized, probably not. It really can’t do the heavy lifting. Perhaps it might delay cooling for a few decades, that’s about the best we could hope for.
“Reform” must be “Dispense with.” This is an expensive hoax.
It’s refreshing to read books published on climate history from ~40-50 years BH (Before Hysteria that is). This one is by H.H Lamb who was Director Emeritus of the Climate Research Unit at the University of East Anglia, titled Climate History and the Future.
He had an interesting opinion of the use of 30 year “weather normals” and their constant substitution every 10 years. I quote:
The practice may be convenient from some points of view but can be, and undoubtably has been, very misleading. Both the 30 year periods so far used (for the 1980’s) were in fact highly abnormal, being amongst the warmest (and 1931-1960 probably the warmest) runs of 3 decades for some hundreds of years past. Moreover, it is the antithesis of the object of a datum to keep changing it.
He went on to suggest that 10-15 years could provide a better estimate of the next year or two, and for 10 year forecasts ahead, 100 year averages updated each decade would be better.
Maybe the “revised” NCA could think about this.
If you have followed the trajectory of Musk in the past month or so, you’ll understand that money was wielded freely to impart the control money gives. Many $billions were wasted on ‘agencies’ and NGOs who were 100% politically motivated. These funds then funded the proposals promoted by just the ‘right people’ and cutting off any that did not toe the DEI, CRT, ESG lines. Let us hope the barn can be fully emptied of the manure, so there will be room for honest science again without political tests.
We’ve heard this song before. “Can we please dial back on the alarmism”? It’s not helping.” All the while, they are pretending to do science, when we all know that it isn’t science at all. There is nothing “wrong” with the climate, and even if there were, there would be nothing we could do about it except to adapt. But how about figuring out what is actually going on first. Is the weather really getting worse? Is SLR really getting worse. Because most of what we see from these so-called scientists is total blather from blithering idiots.
“Brown’s not tossing the NCA out—he’s trying to salvage it from its own excesses.”
If the NCA is to be salvaged – i.e. to be useful for understanding and as a basis for policy – it must be honest in respect to the core assertions of fact.
Does anyone know – honestly – that incremental CO2, CH4, N2O have any influence on any trend of any metric of climate interest? No.
So as a first step, just please stop pretending. We do know enough of the physics of the general circulation, and of the observed LW emission and SW reflection to space, to grasp that the very minor computed radiative effect of increasing CO2, CH4, N2O cannot be isolated in the results for reliable attribution of reported warming or of any other observed climate trend.
Thank you for listening.
“but about making the NCA a document both sides can trust”
It’s only an assessment- it’s not a fact- so nobody should trust it. It might be somewhat useful as a prophecy but no more than any other prophecy- meaning, not particularly useful. Certainly not something to trust.
And for that matter, the document should ideally not be about “sides” in the first place. But there I go, thinking “science” should be about observing and understanding real things. Silly me.
I like that people are now using the word “prophecy” rather than “prediction” or “projection” ! 🙂
I believe “The inconvenient skeptic” by John Kehr has merit. I read this book when it came out and believe it is still relevant. The temperature has been decreasing long term as can be seen in many records. The Sahara desert fed the ancient world. Whatever happened to Egypt? How about the Roman Empire? Real climate change over long periods of time are responsible. The Vikings, the little ice age, the list goes on and on. Those who do not heed the lessons of history will repeat their mistakes.
I read the Biden 5 year climate report. I compared it to the IPCC summary. Total mismatch.
