Experts to discuss new federal climate science report for the U.S.

UPDATED: November 3, 2017. Audio from the news conference posted to the "resources" section below.

On Fri., Nov. 3, experts will discuss the key findings of the Climate Science Special Report (CSSR) which will be released by the U.S. Global Change Research Program that day. The report, which serves as Volume I of the Fourth National Climate Assessment (NCA4), is an authoritative assessment of the science of climate change with a focus on the U.S., and serves as the foundation for efforts to assess climate-related risks and inform decision-making about responses.

New observations and research have increased our scientific understanding of past, current and future climate change since the Third U.S. National Climate Assessment (NCA3) was published in May 2014. The CSSR is designed to capture that new information and build on the existing body of science in order to summarize the current state of knowledge about climate change and provide the scientific foundation for Volume II of NCA4, which is also being released as a draft for public comment.
