Scientists call for ban on solar experiments to curb climate change

To combat climate change, scientists are calling for a ban on solar research.

A letter signed by 60 specialists from 20 nations warns of the dangers of planetary engineering or solar geoengineering. It is being considered by certain nations as a means of cooling the Earth’s surface. According to experts, this initiative should be outlawed globally.

Frank Biermann, a professor of global sustainability governance at Utrecht University, is one of the letter’s signatories. Aarti Gupta, a professor of global environmental governance at Wageningen University in the Netherlands, was also in attendance. Or Melissa Leach, the director of the Sussex-based Institute of Development Studies. The letter was published in the ‘WIREs Climate Change’ publication.

They show that even the most divisive strategy could have negative consequences that outweigh any potential benefits. Solar Radiation Modification (SRM) is a strategy that entails injecting billions of sulfur particles into the middle atmosphere to block a portion of the Sun’s rays from reaching the Earth’s surface.

They have argued that “the deployment of solar geoengineering cannot be governed globally in a fair, inclusive, and successful manner.”

1.1 degrees higher than normal

The intensity, frequency, and length of lethal heat waves have increased due to a 1.1 degree Celsius rise above mid-nineteenth-century values. However, it has exacerbated droughts and mega-storms.

Because of the failure to reduce greenhouse gas emissions, some academics have proposed solar geoengineering as a way to purchase time. The scientific community, on the other hand, does not see it as a viable option.

An “international no-use agreement” is proposed in the open letter, which would prohibit national funding, open-air tests, and patent rights for SRM technology.
