Earth ChangesPrivate companies have raised millions to block the sun. What could go wrong? Posted on December 18, 2025 by Administrator For as little as $1, you can dim the sun — just a tiny bit — to save the world from climate change. At least, that’s the promise sold by a California start-up called Make Sunsets. Your dollar will pay for founder Luke Iseman to drive a Winnebago RV into the hills half an hour outside Saratoga, California, to release a balloon loaded with sulfur dioxide, an air pollutant normally spewed by volcanic eruptions. He and his 1,000 paying customers hope the balloon will burst in the stratosphere, releasing particles that will block sunlight and cool the planet.
