Carbon storage has been a key focus in recent years to draw down natural and anthropogenic sources of carbon dioxide and help the fight against global warming, and particularly focuses on terrestrial forests and soils, as ...
Polar bears are a familiar sight to many through the media as we see evocative images of singular bears floating on isolated ice rafts as they face the harsh realities of climate change shrinking sea ice in the Arctic. Their ...
Climate, tectonics and time combine to create powerful forces that craft the face of our planet. Add the gradual sculpting of the Earth's surface by rivers and what to us seems solid as rock is constantly changing.
