MSNBC’s Ali Velshi on why cable news is suddenly talking so much about climate change

MSNBC is hosting a televised climate change forum this week with 12 candidates running for president in 2020. The event is split across September 19 and September 20 and will cap the network’s “Climate in Crisis” series, a week of dedicated programming on climate change. MSNBC hosts Ali Velshi and Chris Hayes will be questioning the contenders and fielding questions from young voters in the audience.

The forum will be held at Georgetown University and is also sponsored by Our Daily Planet and New York magazine. It comes after CNN held an unprecedented seven-hour climate change town hall with 2020 Democratic presidential contenders earlier this month.
