He took the biggest action on climate change in US history; the goal of the climate bill is to put us on track for a 40% reduction in US emissions by 2030. It’s way too late but that’s clearly not Biden’s fault since he started fighting for it basically as soon as he got into office, and managed to achieve passed legislation which is several standard deviations above the norm for “let’s ignore it until we’re underwater and on fire” US politician status quo.
First of all having a goal isn’t the same thing as having an accomplishment. Second Biden was vice president and a senator for decades. Biden isn’t Mayo Pete who has only had a career long enough to fix bread prices in Canada.
