Nine days ago, the US government left A report “Solar radiation modification” (or SRM) to study the “scientific and societal implications” of the utility to examine the “risks and benefits … as part of climate policy.”
The report’s executive summary states that the technique would “eliminate (clearly offset) all current and future climate change impacts” – but would introduce “further change” to the existing complex climate system, and introduce problems that are not present. Well understood.” Or, as a Politics He puts it.“The White House cautiously endorsed the idea of studying how to block sunlight from hitting Earth in a congressionally mandated report to limit global warming, once confined to science fiction, to help bring it into the legal debate arena.”
But again the report approved the idea Studying It – helps to better understand the risks and also prepare “SRM can be deployed by other public or private actors”. Politico said the report casts doubt on how Congress ordered the review and does not represent new policy decisions related to a process the administration sometimes calls — or as — geoengineering.
“Climate change is having significant impacts on the physical and natural world and human well-being, and these impacts will only grow as greenhouse gas concentrations increase and temperatures continue to rise,” the report said. “Understanding these impacts is critical to enabling informed decisions about the role of SRM in addressing the human challenges associated with climate change…”
The White House has said that any research into improvements in solar radiation must be conducted with “appropriate international cooperation.”
America is not the only one making public statements. According to a Politico report, their report was released the same week that EU leaders opened the door to global solar reform talks.
Policymakers in the European Union have signaled their willingness to start international discussions on how humans can and should limit warming from the sun. “Guided by the precautionary principle, the European Union supports international efforts to assess the risks and uncertainties of climate interventions, including solar radiation improvements and research issues, to encourage discussions on an international framework capable of governance” in a joint statement by the European Parliament and the Council of Europe.
And also “An open letter by More than 60 leading scientists He called for more research Scientific American. You will notice something new A supercomputer to help climate scientists model the impact Insertion of man-made solar-blocking aerosols into the stratosphere:
The machine, named Derecho, began operating this month at the National Center for Atmospheric Research (NCAR) and will allow scientists to run more detailed climate models for research on solar geoengineering, said Christine Rasmussen, a climate scientist at Colorado State University. How man-made aerosols used to reflect sunlight affect precipitation… “To understand the specific effects on thunderstorms, we need to use very high-resolution models that can run for many, many years,” Rasmussen said in an interview. “This fast supercomputer will enable more simulations at longer time frames and at higher resolution than we can currently support…”
National Academies of Science, Engineering and Medicine a Report in 2021 Rasmussen urged scientists to study the effects of geoengineering, which he described as a last resort to combat climate change.
“We have to be very careful,” she said. “I am in no way in favor of moving forward with these kinds of mitigation efforts. The best thing we can do is stop fossil emissions as much as we can.”
