In his blog titled "Linking Science to Policy for Climate Change", LYU talks about his understanding of "climate change and policy". He encourages scientists to keep up good research, and voice not only accurate but also crystal-clear and straight advice for policy-makers.

As the Editor-in-Chief of Advances in Atmospheric Sciences (AAS), LYU also recommends a special issue published in AAS, which review some advances and achievements in climate change research in China and Asia. LYU hopes these reviews could provide important information to policymakers for addressing climate change. The special issue will be free access at Springer Nature website until May 20, 2020.
