CLIMATEWIRE | Climate scientists, environmental activists and philanthropists met privately final month to organize for an anticipated surge of Silicon Valley funding associated to last-ditch measures for slowing international warming.
The two-day gathering on photo voltaic geoengineering — or efforts to extend the reflectivity of the planet via spraying particles into the stratosphere or altering cloud cowl — exhibits how the notion of limiting daylight absorbed by the earth has moved from taboo to believable partially by gaining the acceptance of tech business billionaires.
The assembly on the San Francisco workplaces of the Environmental Defense Fund, which has publicly supported analysis into geoengineering since 2011, was held to assist set finest practices for a coming wave of philanthropic-funded research into the idea, also called photo voltaic radiation administration. The assembly has not beforehand been reported.

Many of the roughly 30 scientists, environmentalists and funders on the assembly would like that tips for photo voltaic geoengineering analysis be established by a federal scientific coordinating physique just like the U.S. Global Change Research Program.
“That hasn’t come to be but,” mentioned Lisa Dilling, EDF’s affiliate chief scientist. The workshop was an acknowledgment of “the truth of the world as we see it now, which is that there are foundations beginning to have an interest on this subject.”
In concept, photo voltaic geoengineering may replicate the cooling response of pure phenomena like main volcanic eruptions, which may launch hundreds of thousands of tons of reflective sulfur dioxide particles miles into the sky. Supporters of the thought — together with billionaires Bill Gates and George Soros — argue that human efforts to redirect daylight may shave a number of fractions of a level off of world temperatures whereas the world financial system kicks its habit to fossil fuels.
But early analysis means that blanketing the stratosphere with aerosols for years or a long time may harm the ozone layer and disrupt climate patterns, placing subsistence farmers and rain-dependent ecosystems in danger. It would additionally do nothing to deal with different harms related to oil, gasoline and coal, reminiscent of native air and water air pollution in addition to ocean acidification.
Another danger of photo voltaic geoengineering is the potential for international temperatures to spike if large-scale spraying applications utilizing planes, balloons or different machines have been to finish earlier than carbon dioxide concentrations fall sufficient to keep away from harmful ranges of warming.
Those considerations are sometimes cited by scientists and activists as causes to review geoengineering and to set tips for the way it ought to be used — if it ever is.
“It is a recognition by one of many nation’s most necessary environmental organizations that geoengineering isn’t one thing that may merely be ignored, that we are able to simply cover our heads within the sand and pretended it’ll go away,” John Holdren, who served as former President Barack Obama’s science adviser, mentioned of the assembly, which he didn’t attend.
“It’s one thing that requires consideration by sensible individuals inside and out of doors authorities,” mentioned Holdren, who now teaches at Harvard University’s Kennedy School of Government.
‘Is it extra harmful than local weather change?’
Whether photo voltaic geoengineering is ever value implementing at some scale is an space of rising curiosity for lecturers, philanthropists and policymakers.
“We must put this in a scientific perspective,” mentioned former Rep. Jerry McNerney (D-Calif.), who throughout his time in Congress used spending payments to create an aerosols analysis program at NOAA and ordered a White House assessment of the photo voltaic geoengineering science.
“Does photo voltaic radiation administration make sense? Is it extra harmful than local weather change? Or is it really one thing that can assist?” McNerney mentioned. “There are loads of unanswered questions that should be investigated earlier than any type of coverage selections are made.”
The EDF-hosted assembly adopted the world’s hottest 12 months on document, and as excessive wildfires, droughts and storms make the consequences of local weather change more and more seen. It additionally got here after the passage of the Inflation Reduction Act and the bipartisan infrastructure regulation of 2021, each of that are making unprecedented public investments in initiatives supposed to scale back the nation’s reliance on planet-warming fossil fuels.
The rising urgency of the local weather downside, coupled with these legislative wins, are why there could possibly be a brand new opening for environmental teams to have interaction extra critically on geoengineering, in accordance with a former EDF official.
“We’re doing rather a lot on clear power, renewables, effectivity, low-carbon metal and so forth,” mentioned Gernot Wagner, a local weather economist at Columbia Business School who labored on the environmental group till 2016, when he left to assist discovered Harvard University’s Solar Geoengineering Research Program. “Despite all of that … the necessity to contemplate photo voltaic engineering is not going away.”
Since Harvard started researching photo voltaic geoengineering, a number of different universities across the globe have launched related applications. They embody the University of Chicago, the University of Washington, Cornell University, Switzerland’s ETH Zürich and the Beijing Normal University in China.
‘Very explosive challenge’
Tech business leaders have lengthy supported finding out photo voltaic geoengineering. Among the backers of Harvard’s analysis program are Gates; former Google government Alan Eustace; and the William and Flora Hewlett Foundation, which was established by one of many founders of the pc firm HP.
Some personal foundations are additionally in search of to immediately fund photo voltaic geoengineering researchers. The Simons Foundation, a charity established by hedge fund billionaire Jim Simons and his spouse, Marilyn, final April dedicated to spending $50 million over 5 years on photo voltaic radiation administration initiatives.
“The basis strongly encourages purposes from scientists within the international south and from investigators who might not have labored in SRM however have experience that might carry new views and expertise to this discipline,” the group mentioned when it introduced the funding alternative.
EDF and its allies are discussing establishing a geoengineering program that might “decrease transaction prices” for donors, in accordance with Wagner, who wasn’t on the San Francisco assembly however mentioned he is aware of lots of the contributors.
“There are a lot of particular person foundations which are on this subject. And what they then usually do is make investments loads of money and time determining who to present the cash to, and reinvent the wheel in some ways,” Wagner mentioned. “This EDF-brokered effort is making an attempt to funnel multiple basis’s philanthropic giving in an identical path and assist information that giving.”
Dilling, the EDF scientist, declined to supply an inventory of attendees however mentioned the group would launch a report on the workshop within the coming weeks that can possible embody contributors’ names. EDF additionally plans to “get some suggestions from extra teams that weren’t in a position to attend,” she mentioned.
The group remains to be making an attempt to find out how deeply to become involved in photo voltaic geoengineering analysis and governance efforts.
“It’s not like we’re a stranger to this subject,” Dilling mentioned. “But getting concerned with any additional developments, we’re principally exploring that proper now.”
They are proper to proceed cautiously, in accordance with McNerney, who’s working for a state Senate seat in California.
Solar geoengineering analysis is “politically a really explosive challenge,” the previous congressman mentioned.
McNerney applauded the scientists, advocates and philanthropists who’re “taking on the accountability to do that as a result of they do not see the federal government with the ability to step as much as the diploma that is wanted to do that correctly.”
