Is there enough land on Earth to fight climate change and feed the world?
Capping global warming at 1.5°C is a tall order. Achieving that goal will not only require a massive reduction in greenhouse gas emissions from human activities, but also a substantial reallocation of land to support that effort and sustain the bios.....»»
Shells, teeth and bones of "weird and wonderful organisms" provide historical environmental clues
An international study shows how chemical fingerprints left by "underappreciated" aquatic organisms could help scientists monitor global environmental change......»»
Same plant, different tactic: Habitat determines response to climate, thale cress study finds
Plants need light to grow, but too much light can induce damage to the photosynthetic complex known as photosystem II. It is known that plants adapted to growing under full sun repair this light-induced damage more. But this repair activity slows dow.....»»
