Flattening the World: Building a Global Knowledge Society

A new "Great Wall" runs along 60% of mainland China's coastlines. But the push to gain more land for economic development could put the country’s coastal wetlands and the services they provide at risk, researchers say.

Two recent international studies are poised to change the way scientists view the crucial relationship between Earth’s climate and the carbon cycle. These reports explore the global photosynthesis and respiration rates—the planet’s deep “breaths” of carbon dioxide, in and out—and researchers say that the new findings will be used to update and improve upon traditional models that couple together climate and carbon.
