Finding an efficient and cost-effective way to capture the carbon dioxide generated by the use of fossil fuels would be a dramatic game-changer in the fight against climate change. We have often heard about clean coal – coal that doesn’t release lots of carbon dioxide when it is burned – but we haven’t really seen it. Our supplies of coal, natural gas, and these days, even oil are plentiful. We just haven’t figured out how to use these things without damaging the environment.
It’s no secret that plastic pollution in the ocean is a huge problem. The most visible sign of this is the Great Pacific Garbage Patch. This accumulation of debris is at least twice the size of Texas and can be seen from space. But now scientists have developed a new way to measure ocean trash – and it turns out there’s more than meets the eye.
