The Senate Finance Committee is weighing a carbon tax, which is one tax the Arizona senator might support. But—shocker—she’s sent mixed signals.

It will make the policies more politically palatable. And it will help compensate kids for the heated world they're inheriting.

There's a reason more big businesses are pushing for a carbon tax—and it's not because they want to fight climate change.

Fossil fuel companies spent record amounts to oppose pro-climate ballot initiatives, and it paid off.

The party might not want to talk about climate change, but voters do.

The conservative version would benefit corporations, not the climate.
