According to a study released on Wednesday, humanity must burn less than a quarter of its proven fossil fuels by 2050 to be able to stop global warming. The paper, which appears in the British journal Nature, says an energy revolution must take place if the world is to meet the goal of limiting global warming to less than 3.8 degrees Fahrenheit above pre-industrial levels. According to the study, this means only 1,000 billion tons of carbon dioxide (CO2) can be emitted between 2000 and...
