Critics claim The list of potential side effects from SRM seems like something out of a disaster movie: harsher winters, fewer or no monsoons, weakened ozone, and droughts that might devastate already parched regions. Several prominent environmentalists have recently called for a halt to all study and evaluation of the technology. Others argue that its implementation is becoming increasingly inevitable because major polluters like the United States are unable to make the drastic changes necessary to avert the potentially disastrous repercussions of environmental change.
“The worry is, what should we do, given that we’re not doing what we should be doing?” said Toby Svoboda, an ecological ethicist at Colgate University and author of a book on the principles of environmental engineering. According to one expert, “politically, this is quite considerable, that the Biden administration would signify their openness to this.”
To those who are unaware, solar radiation management (SRM) refers to a group of highly controversial geoengineering strategies that aim to mitigate the warming effects of the sun and, by extension, the worsening effects of human-caused environmental modification.
The latest White House report, which was purchased by Congress as part of a 2022 appropriations bill, falls short of publishing any new policy regulation on the technology or its use. It does suggest identifying applications for SRM and provides backing for piloting the technology in limited settings.
The paper notes that the potentially irreversible impacts of SRM on human health and the environment are still largely unknown, necessitating further research study. The report suggests using a “danger versus danger” approach to evaluate the potential impacts of SRM against the far more severe outcomes that could occur if the global community actually stops trying to meet environmental standards as expected.
While not denying the possibility of serious drawbacks, the report frames its primary research concerns about SRM in a positive, market-friendly light, wondering how the innovation might ensure the survival of “natural capital dividends,” “strength the weakest links in worldwide and nationwide supply chains,” and “lower the threat of real estate, insurance, and other market failures.”
While disclosing SRM technology would pose “substantial geopolitical dangers,” the paper also argues that the United argues must “prepare… for possible implementation of SRM by other public or personal stars” and develop the means to detect it.
It is not too soon to get this news. China has published some SRM technology, albeit it is very basic and unlikely to have much of an impact on drought. Bill Gates, George Soros, and Jeff Bezos, among other billionaires, have each invested millions of dollars towards SRM study. And privately held businesses financed by equity investors are beginning to question the efficacy of current regulations.
The need for a global agreement to regulate SRM research and application has grown in light of recent developments. The White House report acknowledges that international cooperation of some kind is in the United States’ “finest interest,” but its recommendations fall far short of a global agreement on basic parameters for research and execution.
Former Energy Department official and Alliance for Just Deliberation on Solar Geoengineering founder Shuchi Talati said the study might be a “reward” for these groups in realising they “should have a seat at this table.”
She said that the existence of the study would encourage other countries to consider their role in the issue.
According to some experts, the report shows that a global structure for SRM innovation is highly unlikely. Many are preparing for the chance that the innovation may be established and even released by a single nation or firm due to the failure of existing environment contracts to bind essential variables to emissions, such as the United States.
Recently, V.C.-backed Make Sunsets demonstrated how rapidly an independent star might gain from the present absence of restrictions by offering particular credits for sulphur dioxide thrown into the air via balloons. The project was shut down by the Mexican federal government shortly after it began launching balloons in Baja California earlier this year due to widespread criticism from industry professionals for its methodology and the lack of specific information on the actual cooling results of its work. It’s not hard to imagine a somewhat more evolved firm preemptively fining authorities to propose similar projects that won’t get shut down, despite the fact that they could have far-reaching and unpredictable consequences.
“Given that they are establishing it, ultimately, someone will attempt it,” said Rita Floyd, an assistant teacher in dispute and security at the University of Birmingham. “It’s inevitable that it will happen, at least on a small scale,” he said.
There would be serious moral concerns raised by any attempt at unilateral implementation. By replicating the effects of a volcanic eruption, such as the one that occurred in 1815 and caused Europe to experience the infamous “year without summer,” dizzying aerosol injection is the most enticing method of SRM. Its effects are notoriously difficult to predict and almost impossible to ignore.
The benefits are probably only temporary as well. Experts warn that halting aerosol injections might lead to a “termination shock,” or a sudden, dangerous rise in temperature. Global dependence on the indefinite, costly use of the innovation would result from any implementation.
“There’s a worldwide effect,” Svoboda said. As a result, “what are the principles of deciding for the whole world?” becomes an important question.
According to Lili Fuhr, deputy director of the Centre for International Environmental Law, interest in SRM technology has so far primarily come from major emitters like the United States and China. Native and marginalised communities often voice opposition to research proposals.
Those “requiring this” are “scientists and wealthy individuals from the most polluting nations around the world,” Fuhr said.
The increased interest in SRM innovation in the United States has been criticised by some experts who say it reflects a more fundamental reluctance to achieve less lofty environmental goals, such as reducing total emissions. “It’s extremely lined up with some of the techno-fixated thinking that’s coming out of Silicon Valley,” Fuhr said.
“There is a concern that, possibly, the American public or some section of it may be fooled into believing that this is a complete, total, simple repair,” said Svoboda. “It most certainly isn’t; no one who is apprised of the situation considers this a panacea.”
Some moral philosophers argue that the world will eventually reach a point where the refusal to adopt SRM technology to alter the environment is no longer justifiable. Floyd claimed that the most likely ethical basis for its distribution would be to avert a “tipping-point circumstance,” in certain cases called by geoengineering specialists as “shaving the peak” – reducing the severe consequences of environment alteration in vulnerable communities like the Arctic.
Floyd told me that the international community will likely adopt this innovation after its unilateral release in an apparently reasonable scenario like this, or perhaps after its uncontrolled, for-profit adoption by economic sector stars like Make Sunsets. She claimed that people in small states with “symbolic power,” such as those living on sinking Pacific islands or the Indigenous people of the Arctic, are put under intense pressure in such scenarios to decide whether or not to legitimise the invention.
It’s possible the horse is out of the stable right now. Fuhr told me that one of environmentalists’ greatest achievements to date has been maintaining the public’s perception of SRM as “not a sensible concept, [but] an extremely harmful concept.”
“We are at a genuine threat of… stabilising solar geoengineering as simply another tool in the tool kit,” she said. Not fantastical or terrifying, but plausible under certain conditions.
