As Earth's magnetic shield fails, so do its satellites. First, our communications satellites in the highest orbits go down. Next, astronauts in low-Earth orbit can no longer phone home. And finally, cosmic rays start to bombard every human on Earth.
A group of chemicals known as bi-metallics could help the pharmaceutical industry become more environmentally friendly by cutting the amount of energy used to produce drugs, according to Professor Eva Hevia from the University of Strathclyde, UK, who says that sustainability is a top priority for chemists.
Every year 7 million hectares of forest are cut down, chipping away at the 485 gigatonnes of carbon dioxide (CO2) stored in trees around the world, but low-cost drones and new satellite imaging could soon protect these carbon stocks and help developing countries get paid for protecting their trees.
As temperatures rise in the Arctic, permafrost, or frozen ground, is thawing. As it does, greenhouse gases trapped within it are being released into the atmosphere in the form of carbon dioxide and methane, leading to previously underestimated problems with ocean acidification and potential mercury poisoning.
Detailed biomass maps will enable developing countries to better access climate funds.
Thawing ground sends carbon dioxide and methane into the atmosphere.
With environmental changes locked in for several decades, are we too late to save the Arctic?
