Earlier today, I noted a new study the found Earth is soon to be the hottest it has been in 11,300 years. To make matters worse, The Guardian reports that scientists at Hawaii's Mauna Loa observatory have measured a large increase in CO2 in the atmosphere, suggesting the chances of keeping temperature rise below 2C are "fading fast."
John Vidal at The Guardian reports on the ominous implications of this CO2 increase:
The jump comes as a study published in Science on Thursday looking at global surface temperatures for the past 1,500 years warned that "recent warming is unprecedented", prompting UN climate chief, Christiana Figueres, to say that "staggering global temps show urgent need to act. Rapid climate change must be countered with accelerated action."
Tans told the Associated Press the major factor was an increase in fossil fuel use. "It's just a testament to human influence being dominant", he said. "The prospects of keeping climate change below that [two-degree goal] are fading away."
For a reminder of the math of climate change and why 2C is the "safe" limit for warming, see my post on the case for civil disobedience on climate change.
