The latest print edition of National Review offers a succinct summary of the problems linked to the Paris climate deal.

The agreement, which is to be regarded as a treaty when the Obama administration or its successors and allies seek to enforce it legally, but which is to be understood as not a treaty on the question of whether it must be submitted to the Senate for advice and consent before ratification, fails on key criteria: First, it imposes very high costs in return for promised benefits that would be, according to the climate activists’ own models, negligible; second, it does not serve the national interests of the United States, in that it would place heavy burdens on our economy while placing none on those of India and China, two of the world’s three largest emitters of greenhouse gases; third, it is being pressed on the United States by the Obama administration in an extralegal and unconstitutional process.
