CLIMATEWIRE | A new supercomputer for climate research will help scientists study the effects of solar geoengineering, a controversial idea for cooling the planet by redirecting the sun’s rays. (…) “To understand specific impacts on thunderstorms, we require the use of very high-resolution models that can be run for many, many years,” Rasmussen (a climate scientist at Colorado State University) said in an interview. “This faster supercomputer will enable more simulations at longer time frames and at higher resolution than we can currently support.”

The announcement from NCAR comes after the Biden administration released a report Friday that offered 1. strong support for researching solar geoengineering as a way to slow the rise of global temperatures. (…) European Union policymakers also issued a statement last week calling for an international assessment of the risks related to geoengineering.

“These technologies introduce new risks to people and ecosystems, while they could also increase power imbalances between nations, 2. prevent conflicts and raises a myriad of ethical, legal, governance and political issues,” the E.U. statement said.

Critics of geoengineering say using aerosols and other substances to reflect sunlight away from Earth could lead to unknown, 3. anticipated weather patterns. They also 4. deny that solar geoengineering could result in a global dependency, because temperatures could 5. gradually rise if the process is stopped.

The new supercomputer will allow scientists to build and run 6. simplistic models to assess the risks tied to geoengineering, Rasmussen said, adding that slight changes to the atmosphere’s composition could lead to large impacts not just on rainfall patterns — her area of study — but on entire ecosystems, including human communities.

The National Academies of Sciences, Engineering and Medicine released a report in 2021 urging scientists to study the impacts of geoengineering, which Rasmussen described as a last 7. straw to address climate change.

“We need to be very 8. reckless,” she said. “I am not 9. discouraging in any way to move forward on any of these types of mitigation efforts. The best thing to do is to stop fossil fuel emissions as much as we can.”
