Koonin: DOE Climate Report Finally Brings Clarity, Challenges Alarmist Narrative

by S.E. Koonin, Sept 09, 2025 in ClimateChangeDispatch 

Empirical data shows CO2 boosts growth, extreme weather events are overblown, and policy costs outweigh any benefits.

Protest on a dead planet
A recent Energy Department report challenged the widespread belief that greenhouse-gas emissions pose a serious threat to the nation. It likely soothed Americans irked by forced energy transitions, but you would be wrong to assume it reassured many alarmed by hypothetical climate catastrophes. [emphasis, links added]

There is a disconnect between public perceptions of climate change and climate science—and between past government reports and the science itself.

Energy Secretary Chris Wright understands this. It’s why he commissioned an independent assessment by a team of five senior scientists, including me, to provide clearer insights into what’s known and not about the changing climate.

Collectively, our team brought to the task more than 200 years of research experience, almost all directly relevant to climate studies.

The resulting peer-reviewed report is entirely our work, free from political influence—a departure from previous assessments.

It draws from United Nations and U.S. climate reports, peer-reviewed research, and primary observations to focus on important aspects of climate science that have been misrepresented to nonexperts.

Among the report’s key findings:

■ Elevated carbon dioxide levels enhance plant growth, contributing to global greening and increased agricultural productivity.

■ Complex climate models provide limited guidance on the climate’s response to rising carbon dioxide levels. Overly sensitive models, often using extreme scenarios, have exaggerated future warming projections and consequences.

■ Data aggregated over the continental U.S. show no significant long-term trends in most extreme weather events. Claims of more frequent or intense hurricanes, tornadoes, floods, and dryness in America aren’t supported by historical records.

■ While global sea levels have risen about eight inches since 1900, aggregate U.S. tide-gauge data don’t show the long-term acceleration expected from a warming globe.

■ Natural climate variability, data limitations, and model deficiencies complicate efforts to attribute specific climate changes or extreme events to human CO2 emissions.

■ The use of the words “existential,” “crisis,” and “emergency” to describe the projected effects of human-caused warming on the U.S. economy finds scant support in the data.

■ Overly aggressive policies aimed at reducing emissions could do more harm than good by hiking the cost of energy and degrading its reliability. Even the most ambitious reductions in U.S. emissions would have little direct effect on global emissions and an even smaller effect on climate trends.

Our report is the first from Washington in years that deviates from the narrative of a climate headed for catastrophe. That these findings surprised many speaks to a governmental failure to communicate climate science accurately to the public.

The UK is going back to coal

by A. Montford, Sept 12,2025 in NetZeroWatch

When the wind isn’t blowing and the sun isn’t shining, we rely on so-called ‘firm capacity’ to step in and keep the lights on. In the UK, that means gas-fired and nuclear power stations and pretty much nothing else – the giant wood-burner at Drax is the only significant exception.

Unfortunately, both the gas-fired and nuclear fleets are now very old, and much of the capacity is nearing the end of its life. Regulators have granted extensions to some of the nuclear units, but after 2028 permanent closures are likely. Meanwhile, as much as a third of our gas-fired capacity is expected to retire over the next five years.

Unless these units can be replaced, or their lives extended, we face a capacity crunch by 2030 at the latest. At best that means sky-high prices, and at worst, brownouts – electricity rationing in other words. That is a horrific prospect. As the Spanish found out to their cost during the recent Iberian blackout, when the power supply goes down, people die.

However, replacement is currently looking unlikely. With so much wind and solar on the grid, nobody wants to put money into new power stations, either gas-fired or nuclear. The financial numbers simply don’t add up any longer, either for new units or for overhauls of existing ones.

In theory, we could subsidise our way out of this. Although little or no new capacity has emerged from the government’s capacity market auctions, if caps on prices were removed, in theory someone might take the risk.

However, in practice this won’t happen. That’s because a surge in power demand from new datacentres means that the lead time for a new gas turbine is now eight years. Lead times for nuclear are mostly even longer – the Koreans have delivered in as little as eight years, but everyone else takes much longer. And this is the United Kingdom, where building anything takes an eternity.

Either way, new gas turbines or nuclear will arrive too late to help the UK avoid a capacity crunch.

UK Poll Shows Rising Climate Skepticism, Opposition to Net-Zero Policies

by O. Wright et al., Sept 12, 2025 in ClimateChangeDispatch 

New research finds a sharp rise in climate change skepticism as Brits reject net-zero policies

Ed Miliband's wind farm fantasy
The number of Britons who think the dangers of global warming have been exaggerated has jumped by more than 50 percent in the past four years, new research for The Times reveals today. [emphasis, links added]

One in four voters now believes that concerns over climate change are not as real as scientists have said, amid growing public concern about the cost of the government’s net-zero policies.

Less than a third of the public (30 percent) are in favor of banning new petrol and diesel cars — down from 51 percent in 2021.


Only 16 percent of voters said they would be prepared to pay higher gas bills to encourage the switch to electricity.

Experts said the findings showed that growing climate skepticism within mainstream politics in both Britain and the US was cutting through with voters, as the broad consensus on climate action breaks down.

“Climate change is being politicised [in the UK] in the same way that has been done in the United States,” said Professor Wouter Poortinga, an environmental psychologist at the University of Cardiff.
