2 degree rise

After the INDCs, is 2°C Possible?

Two Degress Goals and Carbon Controls

The last few weeks have seen a flood of Intended Nationally Determined Contributions (INDC) arrive at the UNFCCC offices in Bonn, presumably to be included in the assessment of progress promised by the UNFCCC Secretariat for release well before the Paris COP21.[read more]

Center for Carbon Removal: Beyond Mitigation in a 2C World

October 9, 2015 by Tom Schueneman

Carbon Removal

Later this year ministers, scientists, diplomats and heads of state from more than 190 countries will convene in Paris for COP 21 with the ambitious goal of adopting a binding international treaty to limit greenhouse gas emissions from human activity. The enormity of that task can be distilled to one number: two.[read more]


Maintaining the 2 Degrees Target by Shifting Assumptions

June 14, 2013 by Oliver Geden

After two weeks of largely fruitless climate negotiations at the UNFCCC meeting in Bonn/Germany, the world is one step closer to miss the overarching target of international climate policy: limiting the mean temperature increase to 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.[read more]

14 “Carbon Bombs” Threatening To Blow The Global Carbon Budget & Exacerbate Climate Change

January 25, 2013 by Joseph Romm

The general scientific consensus is that the average global temperature cannot be allowed to warm more than two degrees Celsius [3.6°F] in order to avoid catastrophic climate change. In fact, a two degree rise alone would threaten the water supplies of hundreds of millions of people, lead to global crop declines, bleach coral reefs around the world, and drive up ocean acidification.[read more]

A Major Setback for Carbon Capture & Storage

December 19, 2012 by David Hone

In an excellent presentation at COP 18, Myles Allan made that point that while the UNFCCC and others argue endlessly about the flow rate of CO2 into the atmosphere (i.e. the emissions at some point in time), that fossil carbon continues to add to the carbon stock in the biosphere and that this stock is linked directly with global temperature, ocean acidity and so on. At the current rate of accumulation, the 2 deg.C stock equivalent is passed in about 2043.[read more]
