How to Cooperate with China on Climate

A conversation with Joanna Lewis about what has worked, and what hasn’t, when it comes to bilateral climate cooperation with China.

China is the world’s largest producer of both CO2 emissions and green technology to cut those emissions.

We Crossed 1.5 C. Did We Breach the Paris Agreement?

Here’s what the recent rise in global temperature means for international climate targets.

If you’re not a climate scientist—and maybe even if you are—reading news headlines this month has been confounding and a little scary. “In First, Earth’s Temperature Breached Key Threshold Over a 12 Month Period” is how the Wall Street Journal put it. “Earth Just Experienced 12 Months Of Global Temperatures Above Critical 1.5C Climate Threshold,” …

California lawmakers should rethink the role of dairy digesters in the state’s dairy and livestock mitigation strategy.

Even though California aims to decrease the emissions of methane, dairy operations are rewarded for creating, and capturing, more and more of the planet-warming super pollutant in the form of manure-derived biogas. Today, California lawmakers declined to correct that perverse incentive, but they still have opportunities to rethink the state’s embrace of digesters as its …
