Ice sheets underpin core elements of the Earth’s carbon cycle

Scientists once believed that the ice sheets covering about 10 percent of Earth’s land surface were frozen wastelands, devoid of life and with supressed chemical weathering — irrelevant parts of the Earth’s carbon cycle. Now, a world-leading international team including researchers from Florida State University and the University of Bristol have pulled together a wealth […]

In warming Arctic, major rivers show surprising changes in carbon chemistry

Over the past several decades, the Arctic has begun to show signs of significant ecological upheaval. The rate of warming in the Arctic is nearly twice the global average, and those changes are triggering a cascade of destabilizing environmental effects. Ice is melting, permafrost is thawing, and experts say fires in Arctic forests are as […]
