MP Forces 2025 Govt Answer on SAl/ Chemtrails – Here’s What They Said

[John Tunnard]

Hi everyone,

After sending a strong letter to my MP (Sir John Hayes – South Holland & The Deepings) about geoengineering and the persistent trails we’re all seeing, he actually tabled two Written Parliamentary Questions back in June and has just sent me the government’s replies (dated Nov 2025).

Here’s exactly what they’re now saying on the record:

1. Department for Energy Security & Net Zero (Kerry McCarthy):

“The Government is not deploying solar radiation management technologies an’ has no plans in place to do so.”

2. Department for Science, Innovation &

Technology (Feryal Clark):

“The government has not funded any field-based Stratospheric Aerosol Injection

(SAI).”

…then immediately admits ARIA (the

Advanced Research & Invention Agency) is currently running “small-scale field trials” in the stratosphere with public money (£56.8 million programme launched April

2025). They claim these are “reversible within 24 hours”, “not toxic”, and don’t involve releasing materials… yet.

Classic two-card trick:

“Nothing to see here” → “Well actually we’re already doing outdoor stratospheric experiments, but trust us, it’s harmless.”

Zero mention of the grid patterns, heavy-metal fallout, health impacts, or public consent.

I’ve already fired back a follow-up asking for flight-track analysis over Lincolnshire and an Early Day Motion for a moratorium. Will keep this thread updated with whatever comes next.

Dear Sir John,

Thank you for your correspondence of 11 December available on behalf of your constituent, Mr J Tunnard regarding Solar Radiation Modification (SRM) research. I am responding as the Minister of State for Science, Innovation, Research & Nuclear and apologise for the delay in you receiving this response.

In response to your constituent’s first question, the Advanced Research & Invention Agency’s (ARIA) ‘Exploring Climate Cooling’ programme will explore whether approaches to delay, or avert, climate tipping points could be feasible, scalable and safe. Whilst the government is not in favour of using SRM, we fully support ARIA’s mission to explore important areas of research such as this. ARIA has autonomy over its choice of research, and they are conducting cautious, controlled research aimed at improving understanding of the risks and impacts of SRM.

The small-scale field trials announced by ARIA will be subject to an environmental impact and legal assessment, which will be made publicly available before any outdoor experiment takes place. ARIA’s research and development activity will comply with all domestic and international regulations in this space. More information about ARIA’s planned research activity, including governance aspects, can be found on their website.

In response to your constituent’s second question, emissions from aircraft are strictly regulated by the International Civil Aviation Organization, which sets global standards to limit emissions of oxides of nitrogen (NOx), particulates and other air pollutants from aircraft engines.

When jet fuel is combusted in an aircraft engine, in addition to CO2 emissions, it also produces nitrogen oxides (NOx), water vapor, soot (particulates), and sulphur aerosols from the tailpipe. Contrails form in some atmospheric conditions when the warm moist exhaust emissions from the aircraft mix with the cold and humid parts of the atmosphere. Water from both the aircraft and the atmosphere freeze into ice crystals, which form around soot and other particulates that are emitted from aircraft and then freeze to form ice crystals, which form contrails. Some contrails dissipate quickly, whilst others persist in the atmosphere, forming contrail cirrus.

Production of contrails and contrail cirrus depends on whether the aircraft passes through an ice supersaturated region and the surrounding atmospheric conditions. If the air around the aircraft is very dry, the ice crystals will turn back into water vapor and disappear quickly. Humid air causes the ice crystals to remain and may even spread out, leaving a wider and longer-lasting contrail that may be indistinguishable from naturally occurring cirrus clouds. Aircraft following similar routes can result in multiple contrails naturally forming a pattern in the sky if more than one aircraft is flying around the same time. Further information on contrails can be found on the Met Office’s website [here].

The Department for Transport is not aware of any evidence that contrails cause health problems. At the altitude that contrails are produced, the oxides of nitrogen and particulate matter become dispersed.

In response to your constituent’s third question, there is at present a de facto moratorium on Solar Radiation Modification (SRM) or solar geoengineering. The United Nations Convention on Biological Diversity (CBD) moratorium was adopted at the 10th Conference of the Parties (COP) in 2010. At COP16 in 2024, Parties reaffirmed previous decisions to ensure that no SRM takes place, except for small-scale scientific research studies conducted in a controlled setting and subject to an environmental impact assessment. ARIA’s programme complies with the CBD moratorium. The UK is not aware of any governments arguing in favour of SRM or publicly calling for it to be considered as an emergency measure.

Regarding so-called bans on geoengineering activities by foreign governments, that is a matter for those governments. The UK is not in favour of SRM, is not deploying it and has no plans to do so.

I trust that this information is helpful for your constituent.

Yours sincerely,

Lord Vallance
Minister of State for Science, Innovation, Research & Nuclear

Hi John, 

That is some interesting information. I am from Lincolnshire and have regularly seen them criss-crossing the skies on the east coast. Thank you.

Hi John,

Thank you for this information. I also live in Lincolnshire (at the top of a hill) and I see the chemtrails almost every day! I wrote to my MP Victoria Atkins (with photos) about 2 years ago and said ‘please don’t tell me these are normal condensation trails because they are clearly not’. I just got the standard government reply stating that the government does not conduct any geo-engineering and they were condensation trails. Such an insult to people’s intelligence. I know what I see with my own eyes.  Someone called the planes ‘sky rats’ which I think is very appropriate. I’m astonished that the NFU (farmer’s union) does not demand answers. Surely farmers must look up and see that the trails are falling on their crops. I believe they are cloud seeding and creating never ending rain (to destroy crops) and then heatwaves to finish the job. It seems to follow a pattern in that respect. In the USA some states have successfully passed laws forbidding any ‘spraying’ of skies.

Anyway, thank you for pursuing this.

Cheers John, that reply was food for thought.

Are they tracking ARIA efforts publicly? And if they are autonomous in their research (which means it can change whenever they like), do we know if any of their ethics clearances and methodologies are being published as well? Seeing as it’s taxpayer funded
