In a development climate scientists are calling "depressing" and "troubling"—but not the least bit surprising—the level of the main global warming pollutant has passed a new milestone. Monitoring stations all over the Arctic are measuring more than 400 parts per million of carbon dioxide in the atmosphere, a...
In a new study, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. Under current predictions of global warming, this Arctic sink could be dimin... Read Post
Rising atmospheric carbon dioxide is largely responsible for recent global warming and the rise in sea levels. However scientists have found that this same increase in carbon dioxide may ironically counterbalance some of its negativ... Read Post
You must go back 15 million years to find carbon dioxide levels as high as they are today, Earth scientists report. "The last time carbon dioxide levels were apparently as high as they are today and sustained at those levels, global... Read Post
