Altering Earth’s geophysical environment is a moon shot—and it will be the only way to reverse the damage done. It’s time to take it more seriously.
Geoengineering technology — ways to capture carbon or reflect sunlight from the atmosphere — might become the key to keeping the planet cool.
Some scientists say the world needs to reconsider some human-made ideas to cool the climate as dire warnings about the looming crisis ramp up.
“We think there’s a chance for potential benefits around the world. But we also think there’s the chance for very real risks.”
Geoengineering has always seemed a little out there. But now, it might be our last hope.
Deploying sunlight-blocking aerosols to counteract only some global warming could avoid changes to precipitation
