Tribal concerns rise as solar geoengineering experiments advance

Recent solar geoengineering experiments in Nevada, involving sulfur dioxide balloon releases, have sparked significant tribal consent issues, highlighting a growing conflict in climate intervention strategies.

Hilary Beaumont reports for High Country News.


In short:

  • Solar geoengineering, aimed at cooling the planet, is being tested by releasing sulfur dioxide, but raises environmental and health concerns.
  • Indigenous tribes, whose airspace was crossed during tests, were not consulted, leading to questions about consent and authority.
  • The approach reflects a broader trend of 'green colonialism', where climate solutions overlook Indigenous rights and participation.

Key quote:

“It’s essentially another form of colonialism.”

— Shuchi Talati, founder and executive director of the Alliance for Just Deliberation on Solar Geoengineering

Why this matters:

This issue underscores the delicate balance between innovative climate solutions and respecting Indigenous rights, emphasizing the need for inclusive decision-making in environmental policies.

Ideas to dim the sun 'ignore the root cause' of the climate crisis – and create a cascade of unintended problems, scientists and activists say.

U.S. carbon emissions were falling. Why did they go up in 2025?

The rise comes even before the Trump administration’s pro-fossil fuel policies fully take hold, the authors of a Rhodium Group analysis found.
