[Retrospective] Hans Rosling (1948–2017)

Vie, 03/24/2017 - 00:00
Like a lot of Hans Rosling's admirers, we discovered his work via his famous 2006 TED talk, “The Best Stats You've Ever Seen.” It was a mind-blowing speech (with more than 11 million views to date) with innovative graphics, good jokes, and a profound message: The world is getting better, and even some of the poorest countries are making progress. Hans was a showman, but he didn't sacrifice an ounce of complexity. He was—and this is a term of honor in our house—a data nerd. We sang his praises to just about anyone who would listen.

[Policy Forum] A roadmap for rapid decarbonization

Vie, 03/24/2017 - 00:00
Although the Paris Agreement's goals (1) are aligned with science (2) and can, in principle, be technically and economically achieved (3), alarming inconsistencies remain between science-based targets and national commitments. Despite progress during the 2016 Marrakech climate negotiations, long-term goals can be trumped by political short-termism. Following the Agreement, which became international law earlier than expected, several countries published mid-century decarbonization strategies, with more due soon. Model-based decarbonization assessments (4) and scenarios often struggle to capture transformative change and the dynamics associated with it: disruption, innovation, and nonlinear change in human behavior. For example, in just 2 years, China's coal use swung from 3.7% growth in 2013 to a decline of 3.7% in 2015 (5). To harness these dynamics and to calibrate for short-term realpolitik, we propose framing the decarbonization challenge in terms of a global decadal roadmap based on a simple heuristic—a “carbon law”—of halving gross anthropogenic carbon-dioxide (CO2) emissions every decade. Complemented by immediately instigated, scalable carbon removal and efforts to ramp down land-use CO2 emissions, this can lead to net-zero emissions around mid-century, a path necessary to limit warming to well below 2°C.

[Book Review] Rain check

Vie, 03/24/2017 - 00:00
Make It Rain, Kristine Harper's detailed history of weather control in the United States, includes colorful details of cloud-seeding experiments, but the book is not so much about attempts to control the weather as it is about the political battles waged over the harnessing of the atmosphere: the control of weather control itself. Rather than revealing a history of what we might today call evidence-led policy, the book is a rogue's gallery of policy-led evidence, offering lessons about how science can be used as a tool of the state.
