Solar Geoengineering—What Could Go Wrong?

Richard Heinberg / Resilience Apr 9, 2024 Discussions are underway for pilot projects to block the sun’s heat. But a global solar radiation management program risks creating a carbon bomb on a very short fuse. Dig deeper ( 6 Min. Read )

The Climate Solution That Could Make Poor Countries Richer

Tim Radford / Climate News Network Jan 21, 2020 There is still no certainty that geo-engineering could save the world. But, if it did work, it might repair climate injustice. Dig deeper ( 3 Min. Read )

Picture to illustrate CO2 emissions / greenhouse gas emissions There is an ever growing body of evidence that the way we all live is having a marked influence on our global climate. Recent studies have shown that concentrations of CO2 have reached levels

The Fossil Fuel Industry Is Polluting Our STEM Schools
