Around 300 Columbia and Barnard students marched in a climate strike with thousands of other young activists—including Swedish teen Greta Thunberg—in New York on Friday as part of a global movement to protest climate change. Strike organizers estimated a turnout of
250,000 protesters in New York while the
Mayor’s Office estimated 60,000. Organizers also estimated there were 4 million strikers from over 150 countries worldwide.
