Dimming The Sun To Stop Global Warming Is Not Something Scientists Suggested

News emerged last week saying that scientists want to “dim the Sun” to halt climate change. However, it seems that those reports misunderstood the idea of the study published by researchers at Yale and Harvard. In reality, these scientists did not suggest that dimming the Sun by spraying reflecting particles into the atmosphere is the best idea for stopping global warming.

In this regard, as we already reported here, Dr. Gernot Wagner from Harvard University’s John A. Paulson School of Engineering and Applied Sciences said that “a hypothetical deployment [of a sun-dimming] program is starting 15 years from now, while both highly uncertain and ambitious, would be technically possible strictly from an engineering perspective.”

According to the scientists, as I’ve already presented in the previous article (see link above), such a program is too costly with the current technology. However, solar geoengineering by spraying aerosols in the atmosphere, even though it might be useful, would be an indirect solution to climate change and its global warming.

“The focus of the paper is very different from most of what news reports are saying. Solar geoengineering is not a solution to climate change. That does not address CO2 directly. It has indirect benefits, but frankly, that’s a sideshow. It simply does not address the root cause,” said Gernot Wagner.

“It is a very focused paper that tries to cost out this one possible solar geoengineering deployment scenario. That’s all we’re doing. We’re doing; I’d like to think, a better job in actually coming to real numbers, mostly because we’ve talked directly to aerospace companies and industry folks in this highly hypothetical scenario trying to cost out what a semi-realistic deployment scenario like this would in fact cost. That’s it,” added Wagner.

In conclusion, as I reported in the “Anti-Global Warming Atmospheric Spraying Might Be Effective, But Too Costly With Current Technology” article, dimming the Sun to stop global warming is just a costly solar geoengineering method, not something the Yale and Harvard researchers suggested.
