2021 begins with renewed hope. With vaccines to stem a deadly pandemic. With an unprecedented global effort to repair the economic damage. And with renewed faith in science and the power of collective action to find solutions to global problems.

We need to hold fast to this spirit of collaboration as we confront an existential threat even bigger than Covid-19: climate change. In 2020, climate impacts continued to multiply, even as funding for climate action adaptation—already vastly short of what is needed—was cut back. Extreme weather events including floods and hurricanes compounded the challenges of responding to the pandemic, proving that our health, economic, and climate emergencies are inextricably linked.
