It remains unclear exactly how the upheaval in Paris will impact the United Nations climate change summit, which opens in Paris November 30. Environmentalists from around the world have planned a massive march with 200,000 people expected the day before talks begin.

This all comes after last month shattered records, becoming by far the warmest October ever recorded worldwide. We’ll have more on the Paris climate talks and the outlook for protests later in the broadcast.
