http://www.natureworldnews.com/articles/9139/20140922/global-warming-goal-of-2-degrees-dwindling.htmIn an effort to track carbon emissions, the Global Carbon Project (GCP) published three peer-reviewed articles identifying the challenges for society to keep global average warming less than 2 degrees C above pre-industrial levels. Unfortunately, the findings don't offer much encouragement.
Global carbon dioxide emissions from fossil fuel combustion and cement production actually grew 2.3 percent to a record high of 36.1 billion tons in 2013. In 2014, emissions are estimated to jump another 2.5 percent, which is 65 percent above the level of 1990. Needless to say, this is not offering any hope of reaching global climate goals.

This is what we're already seeing, today. Not someday, not maybe, but today, in real-time.
A world 2C warmer than today would be unrecognizable in many respects.

2. The equilibrium sensitivity of the earth system has probably been been underestimated, and may be over twice as high as previously believed. I think the whole system sensitivity to a doubling of CO2 is probably not 3C as per Charney, but rather the 7.8C calculated by the Apollo-Gaia Project.
