2022 has been a good year for climate action. The Inflation Reduction Act will invest $370 billion toward a low-carbon economy. The Bipartisan Infrastructure Law promises to reduce U.S. carbon emissions while making our infrastructure more resilient to climate change impacts. And wealthy nations agreed to create a fund that will help developing countries who are suffering the worst damages from the changing climate.

Here at the Columbia Climate School, we celebrated our first graduating class of students, who are now out there in the world making a difference. We recently announced that we’re partnering in the creation of a new major for undergraduate students focusing on Climate System Science. And on State of the Planet, we published hundreds of stories aimed toward helping people better understand our current, past, and future climate, and what’s needed to build a safer and healthier future. You can check out some of our favorites below.

The year hasn’t been without its setbacks. The world still may not be doing “enough,” but we’re finally doing something, and that matters. Sustainability is a journey — not a destination — and we’re happy to be on the journey with you. Happy holidays, and see you in the new year!
