In response to the Politico Article; "Sources: Obama, China aim to formally join Paris climate pact ahead of G-20"

This article explains that both the US and China, the two biggest carbon producers in the world, are expected to announce a ratification of the G-20 climate agreement that they signed last year at the UN. These two countries account for more than half of the world's carbon emissions at 55%. On the election front the Clinton camp is heralding this as a major step forward for America and is touting her role in the agreement when she was Secretary of State. On the other side of this is the Trump camp which fears that this ratification will lead to massive regulations that will strangle America's businesses, especially those in the energy sector.

The authors of this piece, Andrew Restuccia and Eric Wolff, are American and are much more invested in this deal because it will directly affect them as well as the rest of the American public. However, this article (like most politico articles) is pretty straight forward in terms of presenting the facts and keeping personal opinions to a minimum.
