New Delhi—A man sifts through trash at a massive garbage site on September 27, a few days before India, the world’s third largest emitter of greenhouse gases, ratified the Paris agreement on climate change.The deal needs to be formally accepted by countries producing at least 55 percent of global carbon dioxide emissions in order to go into force, a threshold it was due to reach in early October with the European Union’s ratification. The Paris accord, signed by nearly 200 countries in December 2015, aims to limit global warming by shifting away from fossil fuels.
