Key takeaways from Tuesday at COP26: On track for 2.4 degrees of warming, and is America really 'back?'

It was gender and science innovation day at COP26 on Tuesday, but most of the focus was on countries wrangling over language around global warming limits and who will pay for the impacts of the climate crisis.

Here's what to know from Day 9 of the summit.

U.S. House Speaker Nancy Pelosi and Rep. Alexandria Ocasio-Cortez -- known as AOC -- showed up at COP on Tuesday with very different messages.

Pelosi reaffirmed House Democrats' plan to pass U.S. President Joe Biden's US$1.9 trillion economic and climate bill next week. "We're very proud of that," she said.
