November 2015 may well go down in history as the month North America reached the climate change tipping point.
Over the course of just 16 days, U.S. President Obama rejected the Keystone XL pipeline; Canadian Prime Minister Justin Trudeau banned oil tanker traffic off the Canadian West Coast (dooming the Northern Gateway pipeline to the dust heap of what will never be), and announced the phase out of fossil fuel subsidies; and Alberta Premier Rachel Notley announced a bold new climate plan that includes a carbon tax, a cap on tar sands GHG emissions, and a phase-out of coal-powered electricity.
Earlier in the year, several tar sands projects were cancelled, $2.6 million was divested from fossil fuel companies, and many international leaders and luminairies -- including Pope Francis -- have come out publicly in strong support of getting serious about combating climate change by switching to a 100% clean economy.
Why so many victories? It's the fruit of a decade of activism and citizen engagement that has seen hundreds of thousands of people attend public events, demontrations and marches both large and small, and millions of people who have signed online petitions demanding that Canadian and American governments do their fair share in the fight for climate stability and justice.
While much has been achieved, and we are now on our way, there is much hard work to be done. It's time to double down, because 100% clean energy is 100% possible wihtin our lifetimes.
