The chemist who gave us the artificial leaf has genetically engineered bacteria to absorb hydrogen and carbon dioxide and convert them into alcohol fuel. When Harvard Professor of Energy Daniel G. Nocera announced he was working with bacteria last year, other scientists cautioned it would be difficult to achieve a productive level of efficiency. At the time, Nocera was aiming for 5 percent efficie
Earth Hasn’t Heated Up This Fast Since the Dinosaurs’ EndPeople are sending carbon into the atmosphere ten times faster than during the hottest period in the past 66 million years. Carbon is pouring into the atmosphere faster than at any time in the past 66 million years—since the dinosaurs went extinct—according to a new analysis of the geologic record. The study underscores just how profoundly h

Global Coal Usage Reaches 44 Year High Alan Taylor June 18, 2014 32 Photos In Focus Earlier this week, BP issued its annual “Statistical Review of World Energy” report. According to the report, coal was the fastest-growing fossil fuel worldwide last year, and “coal’s share of global primary energy consumption reached 30.1 percent, the highest since 1970.” Despite a decrease in coal usage by North
Disturbances, such as wildfires, contribute to the reduction of carbon sequestration in Europe's forests European forests are showing signs of reaching a saturation point as carbon sinks, a study has suggested. Since 2005, the amount of atmospheric CO2 absorbed by the continent's trees has been slowing, researchers reported. Writing in Nature Climate Change, they said this was a result of a declin
