New York City is going after big oil over climate change.
The city is suing five major oil companies for billions of dollars to pay for the cost of protecting New York City from the effects of climate change.
The companies are BP, Chevron, ConocoPhillips, Exxon Mobil and Royal Dutch Shell.
Mayor Bill de Blasio argues fossil fuel companies knew about threats from climate change and intentionally misled the public.
De Blasio also said the city will divest billions of dollars worth of financial interests in fossil fuels.
