Optimism is growing that President-Elect Biden will take on climate change as he pledged during the campaign. In Biden's view, climate change is an "existential threat," warranting an important place among his key priorities. It is far from clear that the new administration will be able to get climate friendly legislation through Congress given Republican control. Nevertheless, with two-thirds of 2020 voters in the U.S. reportedly saying that climate change is a serious problem, and having named former Secretary of State John Kerry as Biden's new Climate Envoy (who signed the Paris Agreement for the U.S. in 2015), it seems like circumstances are falling in place for meaningful support in advancing the fight to reduce greenhouse gas emissions, including opportunities for the new administration to: weave climate objectives into every executive action domestically and internationally; restore the stature of environmental agencies; and implement a clear regulatory plan that combines clean energy with economic growth
