After the encyclical, lessons for climate activism?

When I first heard early this year about the forthcoming papal encyclical on nature and climate change, my first reaction was that this could be one of the biggest moments so far in climate politics but, like many scientific "tipping points", that can only be judged well after the fact. That Pope Francis will be addressing the UN General Assembly and the US Congress on consecutive days in September 2015, the drawing of his title from Francis of Assisi (patron saint of nature), and his training as a chemist all suggest that this issue is a core concern and his advocacy is far from over.

Laudato si, on the care of our common home was issued on 18 June and described by an editorial in The Guardian as "the most astonishing and perhaps the most ambitious papal document of the past 100 years…[it] sets out a programme for change that is rooted in human needs but it makes the radical claim that these needs are not primarily greedy and selfish ones".  Some key points:

Our zero emissions imperative: existential crisis demands emergency action

Last year, we wrote an article explaining why zero has become the most important number for humanity. Since that time, zero emissions has been embraced as an idea that’s time has come by nearly 120 countries, leading European companies, high-profile CEOs, two Pontifical Academies, climate visionaries like Al Gore, mainstream media outlets and, if you can believe it, even the leaders of the G7. We now address the critical issue of timelines.

The time for timid visions and baby steps is over.
The time for our generational mission is at hand.

better is to stop making things worse.

Currently, the two target dates most commonly cited for achieving zero greenhouse gas emissions are 2050 and 2100. Given the extreme weather weirding we are witnessing at current levels of pollution, we shudder to think what 35 years—let alone 85 years—of continued emissions will bring. Everyone can see that the climate is already on steroids and wreaking havoc.


The urgency of our planetary emergency requires that we transition from fossil fuels to renewables not in decades, but in years. We must move beyond what conventional wisdom views as politically feasible to what this existential crisis truly demands: an all hands on deck societal mobilization at wartime speed.
