The IPCC’s Special Report on Climate Change on Land paints a harrowing picture of ways in which climate change is already affecting land across the globe, threatening livelihoods, food, energy, water, and other critical resources. Fortunately, in addition to dire warnings, the report emphasized some good news: food and agriculture can play a major role in adapting to and mitigating climate change. Read more >

How Do Big Oil Companies Talk about Climate Science? Four Takeaways from a Day in Court

, senior climate scientist

In front of a standing room only courtroom audience, the case of The People of California vs. B.P. P.L.C. et al. took an important step forward yesterday.

Together with my UCS colleague Deborah Moore, Western States Senior Campaign Manager, I was lucky enough to get a seat in the courtroom. Here are four of our takeaways from the day: Read more >
