Did your mother ever fail to put breakfast on the table for you and your siblings, Keir? You insult working-class parents who do the world for their kids. How about not stuffing families with sky high net stupid zero energy bills and stealth taxes?
Keir Starmer@Keir_Starmer

I grew up in a working class family, so I know what it's like for parents trying to make ends meet. That’s why tackling the cost of living is my number one priority. From April, 300,000 children will benefit from free breakfast clubs, putting money back in parents' pockets.

"Blaming climate change is safe and socially acceptable. Blaming exposure growth, poor land-use decisions, litigation inflation, or state regulation is politically charged. Climate becomes the scapegoat" says ChatGPT
Patrick T. Brown@PatrickTBrown31

Great article by @RogerPielkeJr It reminds me of a question I recently asked ChatGPT. What do you think of its answer? (I think it probably nailed it). Question from me: I have followed how insurance companies analyze and communicate the influence of climate change on trends in natural disaster damage, and I have noticed something interesting. In their less public-facing communication (such as technical seminars or white papers aimed at the rest of the industry), they conclude that any climate change signal in disaster loss trends is small. However, in public statements (often incorporated into news stories), they often emphasize the impact of climate change on disaster costs and implicate climate change in increased premiums and/or in dropping coverage. From the PR and financial perspective of a private insurance company, why do you think that is? Answer from ChatGPT: You’re not imagining this. It’s a real split in tone between actuarial/technical work and public-facing messaging. The incentives point in different directions. 1. In technical settings, they have to stick to the data Actuaries and catastrophe-modelers don’t get to hand-wave. Their peers will call them out. When you’re pricing risk or trying to separate trend drivers (exposure growth, inflation, asset concentration, vulnerability, regulatory shifts, land-use changes, + maybe a little climate trend), you can’t blame it all on climate. In the internal/technical world, it’s obvious that: • Exposure growth and replacement-cost inflation dominate claims trends. • Market dynamics, underwriting cycles, and regulation matter as much or more. • Climate is there, but it isn’t the main explanatory variable for the last few decades. So the sober assessments are more careful. 2. But public-facing statements operate under a different incentive regime Insurers are commercial, regulated, and politically exposed. Public messaging is a strategic tool, not a peer-reviewed analysis. Several pressures push them toward climate change emphasis: a) It’s a deflection of blame If they say claims are rising because of climate change, then: ○ The villain is external. ○ They are not “price gouging.” ○ They are not failing at underwriting. ○ They are not pulling out of states because they mis-priced risk. ○ They are not admitting the regulatory environment is unworkable. Blaming climate change is safe and socially acceptable. Blaming exposure growth, poor land-use decisions, litigation inflation, or state regulation is politically charged. Climate becomes the scapegoat. b) It helps justify premium increases and withdrawals Insurers don’t want to fight regulators directly if they can avoid it. Saying: “We must raise rates because of climate change” is much easier than: “We misestimated tail risk, your state regulatory caps are unworkable, and inflation in construction costs is killing us.” The climate narrative aligns with a public that already expects bad news. c) It aligns with investor and ESG expectations Large insurers are highly sensitive to headlines and investor sentiment. If they downplay climate risk, they could be framed as not preparing for the future. So the messaging becomes: ○ “We are responsible stewards of risk.” ○ “We take climate seriously.” ○ “We are reducing exposure.” It signals prudence. 3. Media dynamics amplify the climate story Reporters want simple storylines: rising extreme weather → rising premiums But a technically accurate narrative would be: population shifts, higher insured value density, building costs, litigation, regulation, and some climate signal → rising premiums and losses. That’s an un-sexy sentence. The media prefers climate as the central cause. Insurers don’t fight that; they benefit from it. 4. Litigation risk also pushes messaging toward climate There’s a growing legal landscape around climate attribution and corporate disclosure. Under-emphasizing climate exposure is arguably a liability. Over-emphasizing it is not. The safe corporate posture is: • nobody gets fired for overstating climate risk. So internally they hedge the claims. Externally they lean into climate narratives. 5. These companies are not ideological on this point—they’re strategic In short: • Technical analysis must reflect the real drivers of loss. • Public messaging must reflect the most defensible and convenient story. These are not contradictions; they are different optimization problems. Technical teams optimize for analytical correctness. PR, legal, and investor-relations teams optimize for blame-avoidance, pricing freedom, and political safety. The core insight Insurance companies aren’t confused about the numbers. They just communicate in two different registers because they have two different audiences with incompatible expectations. If you swap lenses from “scientific truth” to “organizational incentives,” the behavior makes perfect sense.

For more than 40 years we’ve been told the world faces catastrophic overheating driven by the 'greenhouse effect'; that CO₂ is the primary control knob. There is a growing realisation however that this is a mistaken narrative. Earth’s atmosphere is not a greenhouse. A real greenhouse works mainly by suppressing convection; the atmosphere does the opposite—it moves heat vigorously upward and around the planet. Nor does CO₂ act like a blanket. Yet the blanket metaphor has been embraced as an article of faith by influencers pushing central planning and degrowth ideologies. In the 19th century, scientists Fourier, Tyndall and Arrhenius correctly identified water vapour as the source of 75–85% of atmospheric warming. They did not regard CO₂ as a weather 'control knob' either. Arrhenius thought higher CO₂ might be beneficial but later lowered his warming estimate. Their cautious scientific musings have been hijacked to feed into a climate crisis agenda. Their findings have been recast as justification for urgent, economy-wide restructuring. The 'greenhouse' analogy is misleading and should have been abandoned decades ago. Even accepting the IPCC’s central 3 °C sensitivity estimate for doubled CO₂, the rational response is for only measured mitigation and adaptation over decades—not immediate, self-inflicted deindustrialisation. Even if positive water-vapour feedback was strong—and satellite and reanalysis data increasingly suggest it is not—the direct effects of CO₂ remain modest. And the good news is that reality is reasserting itself. Countries are quietly delaying or abandoning impossible net-zero targets, and engineers are returning to the only proven, workable baseload technology we actually have; nuclear energy.

None of the catastrophic climate predictions have come to pass. Emperor Ed Miliband has been left alone, shivering half-naked on the rapidly shrinking net zero iceberg. Time to follow the science and ditch Net Zero. A thread (1/n)

To generate a single gigawatt of electricity a nuclear power plant will occupy just 3.3 square kilometers (330 ha). A solar panel 'farm' needs up to 194 square kilometers (19,400 ha) but wind turbines will need a staggering 932 square kilometers (93,200 ha). They are being built in the most fertile, forested, vulnerable or valuable & prominent rural or coastal land, to gain visible recognition. Turbines & solar panels are disastrous for wildlife, very costly to build & run & need to be rebuilt in 17 to 20 years. They are unreliable & cannot provide the baseline power essential for any modern society.

A short thread about the UK @metoffice. In the summer they responded to an article I wrote criticising their exaggeration of warm weather. Their response contained material inaccuracies about their own work. They claimed that I was wrong to say they based their wildly unrealistic projections for the UK climate in 2070 on the extreme and implausible scenario known as RCP8.5. Yet their own website says: "We base these changes on the RCP8.5 high emissions scenario". See below.

@dr_andrealove It’s an interesting dilemma to ponder, whether we should try to dissuade fools from believing nonsense, or simply give them the freedom to be conned by ne’er-do-wells. Homeopathy is possibly the biggest fantasy on the planet

Influencers are selling homeopathy as Tylenol “alternatives” — it’s NOT. ⚠️Homeopathy is a scam created in 1796 by a German guy with NO plausibility or evidence. Premise: 1️⃣ what causes a symptom will cure an illness w/the symptom 2️⃣ it’s more potent the more it’s diluted 1/

CO₂ recovered from a historic low point of 190 ppm in the Last Glacial Maximum 21,000 years ago (the threshold for the survival of plants) to drive the modern Green Revolution. Agriculture rose in the Fertile Crescent 9,000 years ago & has since sustained the rise of every human society. Improved CO₂ levels since 1980 had a 70% greening effect, boosting plant growth in an area 3 times the size of the United States.

I asked ChatGPT 5 why Lamarckism is not viable as an explanation for evolution given Popper's epistemoogy. Its answer was rather rambling, but included this pithy gem: "without blind conjecture there is no novelty; without error-elimination there is no improvement."
