While global leaders set a goal in 2009 of keeping climate warming within 2 degrees Celsius, greenhouse gas emissions are on track for far greater warming, according to a report released Wednesday by the U.N. Environment Program.
In fact, Granger Morgan at Carnegie Mellon University poses a question that scientists have been debating more frequently: Is it time to abandon the two-degree goal as unrealistic?
"Today a two-degree target is akin to a 60-year-old man who resolves to be 25 years old next year," Morgan says. "It ain't gonna happen, but it's time to get really serious about achieving what we can."
Meanwhile, the ever-at-the-vanguard Berkeley, Calif., city council voted late Tuesday to draft a proposal by next spring to put stickers on gas pumps citywide to remind consumers that burning fuel contributes to global warming.
