A startup says it has begun releasing particles in the atmosphere, in an effort to regulate the climate

“In my opinion, it is morally wrong for us not to do this — and do it as quickly and as safely as possible,” he said.

But passionate experts in the field say such efforts are premature and could have the opposite effect of what Iseman expected.

“The current state of science is not good enough… to refute or accept let alone implement” solar geoengineering, writes Janos Pasztor, executive director of the Institute. Carnegie’s Climate Management Initiative, is calling for monitoring of geoengineering and other climate change technologies, whether by governments, international agreements or scientific bodies, in an email. “Continuing deployment at this stage is a very bad idea,” he added, comparing the decision to Chinese scientist He Jiankui’s decision to use CRISPR. DNA editing embryo while the scientific community is still debating the safety and ethics of such a step.

Shuchi Talati, a resident scholar at American University who is founding a nonprofit focused on solar geotechnical justice and management, said Make Sunset’s actions could hinder the scientific field, reduce funding, reduce government support for reliable research, and accelerate call for restriction learn.

The company’s behavior led to a long-standing fear that a “rogue” actor with no specific knowledge of atmospheric science or technology might unilaterally choose to regulate climate geoengineering without Is there any consensus on whether it’s okay to do so – or what is appropriate. global average temperature should be. That’s because it’s relatively cheap and technically simple, at least in a rudimentary way.

David Victor, a political scientist at the University of California San Diego, warned of such a scenario more than a decade ago, note that a “Blue Finger, self-styled guardian of the planet… could do a lot of geoengineering on his own,” citing the classic Golden Finger character in the 1964 James Bond film, remembered. came the most for killing a woman by painting her gold.

Some observers were quick to draw parallels between Make Sunsets and a decade-old incident in which an American businessman report dumped hundreds of tons of iron sulfate into the ocean, in an attempt to create a species of plankton bloom that could support salmon populations and suck carbon dioxide from the atmosphere. Critics say it violated international restrictions on so-called iron insemination, in part inspired because there is an increasing number of commercial proposals to sell carbon credits for such work, and argue that it has subsequently impeded research efforts in this area.

Pasztor and others highlight Make Sunset’s efforts highlight the urgent need to establish broad-based oversight and clear rules to guide responsible research in geoengineering and help identify whether or under what conditions a social license is required to proceed with trials or more. As MIT Technology Review first reportThe Biden administration is developing a federal research plan to guide how scientists conduct geoengineering studies.
