Earth Day 2016: Paris Climate Agreement To Be Signed By Over 150 Countries At UN Ceremony In New York

Leaders from more than 150 countries are set to gather in New York City this week to sign the landmark climate change deal struck in Paris last year. The Friday event is the latest in a series of steps to transform the global accord into an actual tool for combatting greenhouse gas emissions and boosting the use of cleaner energy.

The signing ceremony, which coincides with Earth Day, will arrive amid a spate of troubling reports on the latest effects of global warming.
