Dr. Paul Barnes has recently contributed to the UNEP (United Nations Environmental Program) Environmental Effects Assessment Panel on the environmental effects of ozone depletion, UV radiation and climate change. He was also the lead author of a shorter summary report for Policy Makers. 

Of particular note in this assessment is their treatment of the effects of UV light on the transmission of the novel coronavirus and how exposure to sunlight may influence people’s immune response to COVID-19.  They also highlight the environmental effects of micro plastics (and nano plastics), which is an emerging issue of considerable concern. 

Attached are the full panel, as well as Dr. Barnes's summary for policymakers.
