UK government to fund experiments to dim the sun

UK puts up £50 million to dim the sun

How long until geoengineering stops being the stuff of cranks and becomes a line in the British budget? Less than you might think. The UK government will allocate £50 million to a programme of outdoor geoengineering experiments, according to reports published in recent days pointing to an imminent announcement of the funding recipients. The government agency Aria (Advanced Research and Invention Agency) is coordinating the plan, which is complemented by another £11 million project. Dimming sunlight to fight global warming is no longer a talking-head hypothesis and is entering the grants section.

Professor Mark Symes, the programme's director, has described it as «small, controlled outdoor experiments on particular approaches». He added that the funding recipients will be announced within weeks and that there are «strict requirements around the duration of experiments and their reversibility», with a commitment not to fund the release of toxic substances. Professor Jim Haywood, of Atmospheric Sciences at the University of Exeter, is among the names cited in connection with the matter. The fine print, as always, lies in the details that have not yet been published.

What is known about the British geoengineering programme

The figure is concrete enough to be taken seriously: £50 million for solar modification experiments, plus £11 million for a parallel project. This places the UK among the largest public funders of geoengineering research. It is not an academic paper or a computer simulation: these are outdoor trials, with reversibility as a stated condition and no toxic substances, according to the official version.

The announcement comes after years in which anyone who mentioned weather modification in polite conversation was invited to put on a tinfoil hat. The irony is rather delicious: the same administration that until yesterday treated the subject as conspiracy material is now signing cheques for tens of millions to test it in the sky.

Operation Popeye and the precedent nobody disputes

There is no need to turn to science fiction. Operation Popeye, carried out by the United States between 1967 and 1972 during the Southeast Asian war, is considered the first systematic and hostile use of environmental modification techniques. It was declassified in 1974 under pressure from the US Congress. Project Stormfury, dedicated to hurricane control, began in 1962 and ran until 1983.

The conclusion drawn from the documents is uncomfortable: weather modification is not a theory, it is a practice with paperwork. What changes now is the scale, the public sponsorship and the climate excuse. Saudi Arabia, for its part, has been cloud seeding for some time to combat water scarcity without anyone accusing it of conspiring against the sun.

Why some see geoengineering and others see estela

Here the divide opens up. Part of the commentary holds that the British programme confirms what people have been observing for years: persistent trails, veiled skies and aircraft that do not appear on public radar. Another current responds that a controlled, funded and announced experiment is one thing, and a covert global spraying campaign quite another. The distance between the two theses is enormous, but the headline has lumped them together.

Some go further and argue that the real goal is not to cool the planet but to justify new interventions over the population and the economy. The control argument blends with the business one: grants, contracts and an industry that, like all industries, needs to grow. Suspicion is not a fact, but neither is it groundless when £50 million of public money is at stake.

The experiment already happening without being called that

Cloud seeding in arid regions, rain reduction programmes and weather modification projects have been running for decades in various countries. What changes with the British case is the packaging: it is no longer called climate control, it is called solar radiation management and is presented as an emergency response to global warming.

The detail that unsettles people is the asymmetry. In some regions it is done with great fanfare and in others it is vehemently denied. That difference, more than the technology itself, is what fuels distrust. When the same fact is advertised in one country and ridiculed in another, the question stops being whether it exists and becomes why it is being hidden.

What happens now with the Aria experiments

The official timeline points to an announcement of the funding recipients within weeks, along with clarification of when the outdoor experiments will take place. Until then, all there is are statements, figures and promises of reversibility. The ball is in Aria's court.

What has not been published is the technical design, the locations or the evaluation criteria. Nor who certifies that an experiment is reversible, or what exactly dimming the sun means in practice. On this basis, scepticism is not a flaw: it is the reasonable position. And if in a year's time the skies still look just as odd, they will tell us it was all a misunderstanding.
