For the past four years, climate experts have watched with dismay as Donald Trump’s presidential administration has systematically weakened climate regulations, bolstered the use of fossil fuels that drive rising temperatures, and sidelined government climate science and scientists. These actions have combined to set the country behind on the crucial work of reducing greenhouse gas emissions to keep the worst impacts of climate change at bay—and of protecting vulnerable communities and ecosystems.
The election of Joe Biden has changed the prospects for action. The former vice president ran on a platform that included specific, ambitious measures to tackle climate change, including rejoining the Paris climate agreement (which the U.S. exited on November 4) and setting a goal of net-zero carbon emissions by 2050. Climate scientists and environmental advocates have applauded these goals but warn that it will take substantial work to reach them. Among other things, the Biden administration needs to help transition U.S. energy systems, gird against future damage from climate-fueled disasters, and make sure policies incorporate considerations of equity and justice.
To gauge what specific actions climate scientists want to see taken, Scientific American reached out to researchers who work in a variety of areas and asked them to answer one question: What is the most important action you want to see the Biden administration take to address climate change? Below are their answers, lightly edited for style and grammar.
