Uh, oh. Science Journal Nature editorial on #ParisAgreement: “Better out than in”

warrs up with that? ^ | June 1, 2017 | Anthony Watts 

Now that President trump has announced the U.S. will withdraw from the Paris Climate accord, this comes from nature.com and the “that’s going to leave a mark” department:

By Luke Kemp
Continued US membership in the Paris Agreement on climate would be symbolic and have no effect onUS emissions. Instead, it would reveal the weaknesses of the agreement, prevent new opportunities from emerging, and gift greater leverage to a recalcitrant administration.
After the election of President Trump and a two-house Republican majority, many fear for the future of US climate policy. The new administration has indicated that they will abolish Obama’s climate legacy through executive orders.
The repeal of domestic measures will likely result in the US missing its first nationally determined contribution (NDC) under the Paris Agreement, which is an inadequate target of reducing emissions by 26–28% compared to 2005 levels by 2025. If other countries adopted comparable targets, global warming would likely exceed 2°C (ref. 2). The US would need to implement the Clean Power Plan and additional measures to reach its NDC.
Preliminary research suggests that the policies of the Trump administration would instead lead to emissions increasing through to 2025.
Now the predominant concern for much of the international community is that the US will withdraw either from the Paris Agreement, or the overarching United Nations Framework Convention on Climate Change (UNFCCC). The former would take four years and the latter only one. Both are legally possible and within the presidential mandate.
The conventional wisdom is that a US withdrawal would be a worst-case scenario for international climate policy.
However, a sober analysis of the political, legal, and financial impacts suggests otherwise. The modified matrix of risks posed by a recalcitrant US administration summarized in Table1, and explored in detail below, highlights the paradox of US participation: a rogue US can cause more damage inside rather than outside of the agreement.
