LONDON, March 31 (Thomson Reuters Foundation) - Under pressure from indigenous people and environmental groups, Sweden s space agency on Wednesday called off a landmark first test of technology that could pave the way for efforts to slow global warming by dimming sunlight reaching Earth. The Swedish Space Corporation said it had decided not to conduct the technical test, using a high-altitude balloon, that was planned for June ne

Grandiose plans to cool Earth, saving the planet from overheating by utilizing low-tech balloon flights sprinkling particles into the atmosphere to reflect solar radiation back into outer space have been delayed, nobody knows for sure when, or if, it’ll proceed.
The planet-cooling scheme referred to as Stratospheric Controlled Perturbation Experiment aka: SCoPEx headed by Harvard professor Fran Keutsch hopes to save humanity from hothouse Earth with plans to sprinkle aerosols of calcium carbonate and other substances at 12 miles above Earth’s surface to reflect solar radiation to outer space. The initial flight scheduled for June 2021 was set to test the balloon and gondola equipment sans release of aerosols until later in the year.

A solution to global warming? In an attempt to fight the rise in temperature on Earth, a team of American researchers had an … amazing idea: artificially cool the atmosphere using a balloon. How? ‘Or what? Releasing large amounts of calcium carbonate dust several kilometers above the Earth’s surface.
But in the face of much criticism, scientists and the Swedish Lapland space center with which they were working on this project changed their minds.
Mitigate the effect of solar rays
The start of the tests was scheduled for June. A test launch of the balloon should have taken place from the small Esrange space center near Kiruna, north of the Arctic Circle, Sweden, as part of the project called “SCoPEx” (“Stratospheric Controlled Disturbance Experiment”).
