Atmospheric cooling technology: an alternative method to solve climate change

The National Academy of Sciences said on Thursday that the United States must seriously consider the idea of repairing the atmosphere to cool the warming earth, and speed up research on how and whether humans should artificially intervene in natural mechanisms.

This report was written by an institute established in abraham lincoln, which aims to provide expert advice to the government, but it does not recommend using solar geoengineering to reflect heat back into space. At least not yet.

However, according to the report, the extreme weather conditions caused by climate change have deteriorated since the college last studied the issues of great concern in 20 15, so it is necessary to explore an emergency plan. This requires cooperative research on the feasibility of atmospheric remediation technology, its potential dangers and side effects, its moral problems and potential political consequences.

The report studies three possible methods of atmospheric cooling: placing heat reflecting particles in the stratosphere, changing the brightness of ocean clouds, and thinning the upper clouds.

Lynn Russell, an atmospheric chemist at the Scripps Institute of Oceanography, said: "Climate engineering is indeed a stupid idea, but it may not be as stupid as doing nothing or continuing to do what we have been doing." He is one of the authors of the report. "It has many risks, and it is very important for us to know as much as possible about these risks."

The expert group suggested that the research funds should be increased several times to reach 40 million dollars per year, and the research should be terminated when unacceptable risks are found.

Chris field, chairman of the Stanford University Committee, said: "Honestly, I don't know if this makes sense."

Critics such as Raymond Pierrehumbert of Oxford University worry that "moral hazard" will provide them with attractive choices to use suspicious technologies instead of reducing carbon pollution. He said that the word geo-engineering makes people mistakenly think that the earth's heat can be controlled like a thermostat.

Andrew Deissler of Texas A&M University believes that geo-engineering is a safety feature of the earth, just like the car airbag that you hope will never be needed.

Mathea Macnutt, the director of the research institute who presided over the early research, said that the new report was more influential than the report of 20 15, detailing the government's supervision and how to carry out the research.

Geoengineering is too risky, don't you consider it?

Walid abdullah, a former chief scientist of NASA and a member of the 20 15 team, said: "Playing with fire is very different from studying fire, so we need to know enough about fire before deploying it. "When taking risks in climate change, you must carefully test those options that are extremely risky."
