Geoengineering : Seven extreme climate fixes

Given how the United States are burning, it is not extraordinary that National Geographic published in mid July on geoengineering, or if you prefer, solutions to alter directly our warming climate. Among those solutions are pumping up plankton, artificial volcanoes, seaweed farms (something new), biochar, greening the desert (see this post), cloud making ships and… Continue reading Geoengineering : Seven extreme climate fixes

Sometimes the simplest solutions can have huge impacts. Indeed, painting dark roofs white can decrease by up to a fifth  buildings air conditioning use. Generalized globally, this could make a big difference. Scientists at the Concordia University estimated that painting one percent of the world’s urban surfaces white could reduce carbon dioxide emissions by 130… Continue reading Painting roofs white
