Solar geoengineering could start soon if it starts small
—David W. Keith, founding faculty director of the Climate Systems Engineering initiative at the University of Chicago, and Wake Smith, a lecturer at the Yale School of Environment and a research fellow at the Harvard Kennedy School.
For half a century, climate researchers have considered the possibility of injecting small particles into the stratosphere to counteract some aspects of climate change. The idea is that by reflecting a small fraction of sunlight back to space, these particles could partially offset the energy imbalance caused by accumulating carbon dioxide, reducing warming as well as extreme storms and many other climate risks.
Cooling the planet with this form of solar geoengineering, called stratospheric aerosol injection, would require a purpose-built fleet of high-altitude aircraft, which could take decades to assemble. This long lead time encourages policymakers to ignore the hard decisions about regulating its deployment.
Such complacency is ill-advised. Our analysis suggests a country could conceivably start a subscale solar geoengineering deployment in as little as five years, one that would produce unmistakable changes in the composition of the stratosphere.
If we are correct, then policymakers may need to confront solar geoengineering—its promise and disruptive potential, and its profound challenges to global governance—earlier than is now widely assumed. Read the full story.

+ The flawed logic of rushing out extreme climate interventions. Forging too fast into controversial terrain can spark backlashes that stall research and limit our options. Read the full story.
+ This technology could alter the entire planet. These groups want every nation to have a say. Nonprofits and academic groups are working to help climate-vulnerable regions take part in the high-stakes global debate over solar geoengineering. Read the full story.

The big story
October 2023
We’re in a very strange moment for the internet. We all know it’s broken. But there’s a sense that things are about to change. The stranglehold that the big social platforms have had on us for the last decade is weakening.
There’s a sort of common wisdom that the internet is irredeemably bad. That social platforms, hungry to profit off your data, opened a Pandora’s box that cannot be closed.
But the internet has also provided a haven for marginalized groups and a place for support. It offers information at times of crisis. It can connect you with long-lost friends. It can make you laugh.
The internet is worth fighting for because despite all the misery, there’s still so much good to be found there. And yet, fixing online discourse is the definition of a hard problem. But don’t worry. I have an idea. Read the full story.
