Four hundred thousand people marched on the streets of New York City on Sunday calling urgent attention to our changing climate in what is being touted as the largest climate demonstration in history. Nearly 3000 solidarity marches and events around the world and in other US cities also took place on Sunday. The show of public force comes just two days before a UN climate summit in New York on Tuesday.

Meanwhile, a day after the People’s Climate March, thousands of those same activists conducted a mass sit-in near the New York Stock Exchange. That action was dubbed Flood Wall Street, and was not officially affiliated with the march. More than 100 blue-clad demonstrators were arrested.

MSNBC said, “Whereas [the] march was designed to appeal to the broadest slice of potential supporters possible, Flood Wall Street is more overtly radical in both its rhetoric and tactics.” The Flood Wall Street protesters carried a giant 15 foot inflatable balloon symbolizing a “carbon bubble,” which police apparently deflated.

And, in what seems to be a direct outcome of public pressure, the Rockefeller family announced that it would be divesting some of its vast fortune from fossil fuel-based investments.
