Die von der britischen DARPA inspirierte Advanced Research and Invention Agency (ARIA) untersucht derzeit „Optionen zur aktiven Kühlung der Erde“.

The UK’s DARPA-inspired Advanced Research and Invention Agency (ARIA) is currently “exploring options for actively cooling the Earth.”

In an update post last week, ARIA highlighted the publication of three research theses for climate-related programs.

In addition to “[**Forecasting Tipping Points**](https://www.aria.org.uk/wp-content/uploads/2024/05/ARIA-Forecasting-Climate-Tipping-Points-Programme-Thesis.pdf)” and “[**Synthetic Plants for a Sustainable Future**](https://www.aria.org.uk/wp-content/uploads/2024/06/ARIA-Synthetic-plants-for-a-sustainable-future.pdf)” ARIA also published its “**Exploring Options for Actively Cooling the Earth**” thesis, which narrows the scope of one of ARIA’s [opportunity spaces](https://sociable.co/government-and-policy/uk-darpa-aria-control-weather-geoengineer-climate/) called, “**Managing our climate and weather through responsible engineering**.”

According to ARIA program director Mark Symes, who wrote the “**Exploring Options for Actively Cooling the Earth**” [thesis](https://www.aria.org.uk/wp-content/uploads/2024/05/ARIA-Actively-cooling-the-earth-programme.pdf):

ARIA’s reasoning for wanting to actively cool the Earth is based upon the belief that current plans to tackle climate change are insufficient to meet the 1.5°C global warming threshold target, and that there may be other irreversible tipping points, such as “***the melting of the Arctic winter sea ice […] dieback of the Amazon rainforest and consequent ecosystem loss, and collapse of the major land-based ice sheets, leading to significant global sea level rises***.”

I’m sorry but you need clean energy. Lots of it to make a change. A fusion breakthrough would help.
