As more and more countries around the world struggle to meet their carbon emission reduction targets, they are looking for all kinds of solutions to work around the problem. One of those is carbon capture and storage (CCS). This atmospheric … Continue reading

New cloud geoengineering research casts doubts: 70x less effective & smallest salt aerosols increase warming

Marine cloud seeding is one of the best documented geoengineering proposals. It is centred around the idea that some forms of clouds tend to have a net cooling effect on the Earth’s climate, by increasing albedo or reflectivity. Our regular … Continue reading

Plants have 34% less breathing pores due to 150 years of rising CO2
