No, Scientists Didn't Only Suggest The Sun to Stop Climate Change

A new report from researchers at Yale and Harvard last week, which suggested c dimming the sun değişik to alleviate climate change, was alarming. The problem is, these reports misinterpreted the survey, we actually call it solar generator.

Instead, he was a lecturer in Yale, Wake Smith, and co-ordinator Gernot Wagner, a research fellow and lecturer at Harvard, and attempted to calculate the cost of one of the most discussed methods of solar geoengineering – Stratospheric Aerosol Injection (SAI) – basically involves discharging a group of sunlight particles into the upper atmosphere. The authors confirmed that such a strategy is a "remarkably inexpensive" way to cut global warming. Research published on Friday Environmental Research Letters.

’The newspaper's focus is very different from the newspapers' focus, ı said Wagner, co-director of Harvard's Solar Energy Engineering Research Program, in his interview with Earther. One of the biggest differences between how the report is handled and what the authors write is the assumption that it presents research as a solution for climate change.

Ir Solar geoengineering is not a solution to climate change, Wag said Wagner. Or This does not directly address CO2. There are indirect benefits, but frankly, this is a show. It's not just the root cause. "

The best way to think about new research is the real control of a proposed method (highly controversial and potentially catastrophic) where climate change may be partly. appealed. The researchers reviewed the recommended methods for placing the sulphate particles in the lower stratosphere to reduce the earth's temperature and determined that they would be the most expensive of a special high-altitude aircraft called SAI Lofter (SAIL). An effective way to do this. They predicted that such a program would cost a little more than $ 2 billion a year for the first 15 years and yıl reduce half of the temperature change rate from the first year of the program Böyle.

Climate change is an increasingly dangerous antagonist and we are not doing a great job.

En This is a very focused study that tries to cost a single solar power generator distribution scenario. All we do is, ner said Wagner, Earther. Uk In fact, we're doing a better job of approaching the real numbers, because I've talked to aeronautical companies and industry people in this highly hypothetical scenario at whatever cost. The cost of such deployment scenario is actually. This much."

As the researchers pointed out in their analysis, “solar geoengineering is often described as“ fast, cheap and imperfect Araştırma. However, they prove the first point and the second evidence – and these reports seem to be the loss of translation. In a study by CNN, the Daily Mail, and others, the authors say, "They have made no decision about the desirability of SAI."

Olan We show that a hypothetical program that has only been going on for 15 years, will be technically possible from an engineering perspective, even if they are both ambiguous and ambitious, “they say. ”It would also be extremely cheap.“

Another object of the article was that such a technology could not be distributed in a confidential way. The authors draw attention to this issue, considering that ”thousands of flights are needed each year by airplanes operating from an international base series Yazar.

Wagner said the research was a big step forward for a very narrow question about the solar generator, but further research on the subject should be done, as noted by other experts in the field. If the effects of solar geoengineering are not fully understood, such a method can be adopted without a clear understanding of its potential consequences.

; Genie's bottle is out of the bottle n from Germany's Institute for Sustainability Studies in Potsdam, Germany, which has published research on the solar generator, in a statement to Earther in March. ”And I don't believe you won't talk about it, it's going to eliminate the idea.“

It is clear that the potential impact of climate change on all aspects of life can be catastrophic, following the release of the second volume of the Fourth National Climate Assessment (a large-scale federal report on climate change that the Trump administration is trying to bury). . As reported by the report, the effects are already felt in the United States.

However, there is no simple or easy solution to mitigate climate change. Unlike any suggestion, there can be a huge over-simplification.
