Real-world geoengineering experiments revealed by UK agency

Trials will test ways to block sunlight and slow climate crisis that threatens to trigger catastrophic tipping pointsReal-world geoengineering experiments spanning the globe from the Arctic to the Great Barrier Reef are being funded by the UK government. They will test sun-reflecting particles in the stratosphere, brightening reflective clouds using sprays of seawater and pumping water on to sea ice to thicken it.Getting this “critical missing scientific data” is vital with the Earth
