The last time carbon dioxide levels were this high was a million years ago. The global community needs to reduce emissions by 80 percent to stop the increase in CO2 levels. The data was reported by the National Oceanic and Atmospheric Administration.

Yes, one is with and the other without oxygen, and both divert waste from the landfill—but in terms of the end products, what is the advantage of anaerobic digestion? Simply put, does society face a shortage of compost or renewable energy?

Even as the world (unsuccessfully) tries to formulate a treaty to get nations to reduce their carbon emissions, researchers indicate it may be too late - the tipping point may have been reached. But what if CO2 could be extracted from the air?

New research suggests that huge domes of carbon dioxide hover over urban areas, which is prompting some scientists and policymakers to stress the importance of cities as the frontlines of the war on greenhouse gas emissions.
