Describing the Paris Climate Agreement as the "single best chance that has to deal with a problem that could end up transforming this planet", United States(US) President Barack Obama, in a speech in Hangzhou, China, before the meeting of G20 leaders, confirmed that the US and China had ratified the planet-saving agreement as he declared: :History will judge today's effort as pivotal."
Signed last December at Paris, France, the Climate Agreement, among other things, seek to cut CO2 emissions to a rate that would keep global temperature rises below 2 degrees Celsius.
United Nations(UN) Secretary General Ban Ki-moon said both President Obama and China's Xi Jinping had been "far-sighted, bold and ambitious" in ratifying the Paris Agreement, which could combat the adverse effects of climate change.
Before the US and China ratified the Paris Climate Agreement, according to the BBC-News, 23 nations had done so accounting for just one percent of emissions. With the signing of the US and China, who are responsible for 40 percent of the world's emissions, the Paris Climate Agreement has now passed an important threshold toward its final implementation.
