White House cautiously opens the door to study blocking sun’s rays to slow global warming
07/01/2023 09:42 AM EDT
The White House offered measured support for the idea of studying how to block sunlight from hitting Earth’s surface as a way to limit global warming, in a congressionally mandated report that could help bring efforts once confined to science fiction into the realm of legitimate debate.
The controversial concept known as solar radiation modification is a potentially effective response to fighting climate change, but one that could have unknown side effects stemming from altering the chemical makeup of the atmosphere, some scientists say.
The White House report released late Friday indicates that the Biden administration is open to studying the possibility that altering sunlight might quickly cool the planet. But it added a degree of skepticism by noting that Congress has ordered the review, and the administration said it does not signal any new policy decisions related to a process that is sometimes referred to — or derided as — geoengineering.
“A program of research into the scientific and societal implications of solar radiation modification (SRM) would enable better-informed decisions about the potential risks and benefits of SRM as a component of climate policy, alongside the foundational elements of greenhouse gas emissions mitigation and adaptation,” the White House report said. “SRM offers the possibility of cooling the planet significantly on a timescale of a few years.”
Still, the White House said in a statement accompanying the report, “there are no plans underway to establish a comprehensive research program focused on solar radiation modification.”

One of the many effects of global warming is sea-level rise due to the melting and retreat of the Earth's ice sheets and glaciers. As the sea level rises, large areas of densely populated coastal land could ultimately become uninhabitable without extensive coastal modification. In order to stave off this possibility, carbon emissions need to reach net negative, a state that is hard to achieve under current circumstances.

Climate change: The 'insane' plan to save the Arctic's sea-ice
9 hours ago
Perched on sea-ice off Canada's northern coast, parka-clad scientists watch saltwater pump out over the frozen ocean.
Their goal? To slow global warming.
As sea-ice vanishes, the dark ocean surface can absorb more of the Sun's energy, which accelerates warming. So the researchers want to thicken it to stop it melting away.
Welcome to the wackier side of geoengineering - deliberately intervening in the Earth's climate system to try to counteract the damage we have done to it.
[...]
The ultimate goal of the Arctic experiment is to thicken enough sea-ice to slow or even reverse the melting already seen, says Dr Shaun Fitzgerald, whose team at the University of Cambridge's Centre for Climate Repair is behind the project.
