Here is a fact of how things work in the United States that people don’t seem to like. The only real way change works is when both parties agree to make change. Further, our government is not set up so that the President can do anything he pleases, unlike what Trump might want everyone to think.
Consequently, blaming Biden for any legislation, like climate change, not passing is B.S. because Congress has to pass legislation first. Guess what, a 50/50 split in the Senate means that enough people from both parties have to agree.
Unfortunately, this hurdle on change is by design, it’s not a bug. It was built, however, on the premise that those elected would actually govern and would not simply vote along party lines even to vote against the best interests of their constituents.
