“Climate justice” can mean many things: for me (John) it is meaningful action taken to deal with the most pressing problem of the 21st century, the problem of climate change. Importantly, this means moving the world toward the most progressive possible global climate treaty, contributing to the strongest possible social movement participation in creating that treaty, and through both of these channels helping to bring about the creation of a low-carbon, sustainable, equitable, and deeply democratic future. I believe that if we are to pass on a world worth living in to your own and the next generation, this movement for climate justice must become the biggest (and most effective) the world has ever seen.

A growing international scientific consensus has emerged that there is now only a 50 percent chance that the official United Nations maximum target of limiting the rise in average temperature to 2 degrees Celsius by the year 2050 would effectively avert irreversible climate change.
