This Democratic senator says Biden’s climate efforts are falling short — and young voters are noticing

Well, too late to do anything about it. The candidates are now, as the article says,

“Come November they are going to be choosing between two individuals — Joe Biden and Trump, who is dramatically worse when it comes to making any progress at all on climate,” she said.

That's it. If we want anything different, we have to look for congressional candidates who will change voting such that 3rd party candidates can be taken seriously, and we have to fill ballots with better choices during primaries. After primaries, in our "first across the finish line" system, it's all over except for the big tug-of-war between the two parties.

And that takes time. So this year, you're either voting for Biden in hopes of "best we can do right now," or literally any other action (including inaction) is giving it over to a worse outcome for our climate goals.
