Geoengineering is an ambitious set of methods proposed by scientists to help mitigate the effects of climate change. And one type in particular—solar geoengineering—has been the subject of growing debate. Solar geoengineering involves several techniques, including injecting reflective particles into the stratosphere to reduce the amount of solar radiation and heat that reaches the Earth. This proc...

De-extinction describes the process of creating an organism that belongs to or closely resembles an extinct species. While this process was once a science-fiction fantasy explored in films like Jurassic Park, recent biological and technological breakthroughs suggest that reviving extinct creatures, like the passenger pigeon and the woolly mammoth, could soon become a reality. The benefits of de-ex...
