President Barack Obama and his Chinese counterpart, Xi Jinping, announced Saturday in Hangzhou that the world’s two leading greenhouse gas emitters have formally acceded to the terms of last year’s Paris Agreement on climate change.
The two nations account for 40 percent of the planet’s atmosphere-warming pollution. Obama pointed to the action Saturday as a key step in assuring that the 195 country-strong deal reached last December in France does lead to an effective response to climate change.
“We have a saying in America — that you need to put your money where your mouth is. And when it comes to combating climate change, that’s what we’re doing, both the United States and China. We’re leading by example. As the world’s two largest economies and two largest emitters, our entrance into this agreement continues the momentum of Paris, and should give the rest of the world confidence –- whether developed or developing countries -– that a low-carbon future is where the world is heading.”
Nations were able to sign the Paris Agreement starting on Earth Day of this year. The Paris Agreement will take effect only when 55 countries that represent 55 percent of all GHG emissions on Earth ratify, accept, approve, or accede to it.
With the acceptance by both China and the U.S., 179 nations and the European Union have indicated approval, but only 26 have ratified it. The ratifying nations account for about 39 percent of planetary GHG emissions.

The Paris Agreement was reached at the 21st Gathering of the Parties of the UNFCCC. As the first international agreement aimed at limiting the warming of the planet’s atmosphere and oceans now underway as a result of human exploitation of fossil fuels, the Paris Agreement does not require any specific actions by nations to reduce GHG emissions.
Instead, the accord is aspirational. As the United Nations assistant secretary-general for climate change told CBS News last December, it is a plan that aims to “name and encourage” the nations who fail to meet commitments to reduce GHG emissions.
Those commitments, known as “nationally determined contributions,” are to be “ambitious” and “represent a progression over time.” The content of NDCs are to be established “with a view to achieving the purpose of the [Paris Agreement].”
The core of the Paris Agreement is the specification of climate change-related objectives:
“(a) Holding the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change;
“(b) Increasing the ability to adapt to the adverse impacts of climate change and foster climate resilience and low greenhouse gas emissions development, in a manner that does not threaten food production; [and]
“(c) Making finance flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development.”
During the first half of this year the average worldwide temperature was about 1.3 degrees Celsius above that recorded in 1880. Moreover, a study published in Nature on June 30 concluded that all of the NDCs in place so far would not lead to warming of less than 2 degrees Celsius.
