One Cooling Credit offsets one ton of CO2 warming for a year. How does one gram of SO₂ offset one ton of CO₂ warming for a year?
Estimates vary, but a leading researcher cites "geoengineering’s leverage is very high — one gram of particles in the stratosphere prevents the warming caused by a ton of carbon dioxide," and “a gram of aerosol in the stratosphere, delivered perhaps by high-flying jets, could offset the warming effect of a ton of carbon dioxide, a factor of 1 million to 1."

Own a piece of history and offset the warming effect of ten tons of CO2 for a year. The balloon pictured will be cut up into 99 individual pieces. Each piece sold will come with a certificate of authenticity with a limited edition serial number 1 to 99.
If you order more than one, you get a bigger piece. Buy the whole thing intact and we'll frame it for you. Create an account on Make Sunsets to track the fulfillment of deployments.

Catalog note: The balloon's original weight is 600 grams. It was launched on Sunday, Feb 12, 2023, in Reno, Nevada. It was then recovered the next day near Outingdale, California. Time Magazine was given exclusive access to report on the deployment and you can see photos of the balloon in this article. Here is our blog post about the deployment.

We should obviously be doing solar geoengineering. We are on track to radically reduce emissions in the coming years but thermal damage will lag our course correction so most of our climate pain is still ahead of us. Why risk destabilizing the West Antarctic ice sheet or melting the arctic permafrost or wet bulbing a hundred million people to death? Solar geoengineering can incrementally and reversibly buy down the risk during this knife-edge transition to a better future. We owe future generations to take all practical steps to dodge avoidable catastrophic and lasting damage to our planet.

It’s a small way I can help with a seemly very large problem! For what it’s worth, $200 offset 20 tons of CO2 is a great win!

At some point, you learn about reflective particles as a potential cooling method. The next question would be: 'Is anyone doing this now?' This led to the discovery of Make Sunsets, a team that not only explores solar radiation management techniques but also works to implement them. It's incredibly reassuring to see a group like Make Sunsets pushing the boundaries of scientific research, aiming to create a cooler, more sustainable future for everyone.
