As the lead author of the Terrestrial Ecosystems Working Group within the EEAP, Dr. Barnes works with a dozen other scientists to assess the interactive effects of changes in stratospheric ozone, ultraviolet radiation, and climate on terrestrial ecosystems and biogeochemical cycles. This Working Group just finalized a major Quadrennial Report that will be published early in 2023. In addition, Dr. Barnes also serves as one of 3 Co-Chairs of the EEAP. In this capacity, he represents the EEAP at the annual Meeting of the Parties (MOP) where he interacts with the Co-Chairs of the other UNEP scientific assessment panels and presents summary findings to policymakers.
