It's nearly time for a reboot on global climate action.
The Kyoto Protocol of 2008 through 2012 succeeded in introducing the world to the concept of coordinated climate action. Aside from creating a weak European carbon market, however, it did little to actually ratchet greenhouse gas levels. Nations that met their obligations under the protocol did so with the help of economic downturns. The US never ratified the pact. Canada eventually withdrew, avoiding repercussions for the climate-changing carbon billowing from its tar sands mines and processing facilities. An extension to the protocol will govern just one out of every seven carbon dioxide molecules produced by humanity during the next five years.
