Dr. Sadie Ryan and a team of scientists from around the world recently summarized key advances in the scientific understanding of the climate system.

Published in Global Sustainability, this new study offers a broad selection of scientific messages pertaining to temperature changes, biodiversity, land carbon sinks, disease incidence, and other global issues in a format that is accessible to non-experts.

As explained in Carbon Brief, the goal of this year’s report is to facilitate the rapid integration of recent scientific findings into policy processes and global governance.

One of the 10 insights focuses on dengue, a mosquito-borne viral infection studied by Dr. Ryan. The new paper argues that dengue fever is likely to increase by the end of the century, making mosquito-control more important than ever.
