In 2015, nearly 200 countries came together to adopt the Paris Agreement. Parties to this historic accord committed to take steps both to limit warming to well under two degrees Celsius above pre-industrial levels and to increase resilience to the impacts of climate change. National climate goals are at the heart of the agreement and are critical to achieving its objectives. Every five years, countries submit their goals—called “Nationally Determined Contributions,” or NDCs—which are to be increasingly ambitious over time. The agreement also encourages countries to submit and update “adaptation communications” that articulate their priorities, needs, and strategies for guarding against climate impacts. To support the Paris Agreement, California is sharing its “ocean-climate contribution” at COP24.
