It will be a challenge for the Globe to bring civility to comments on partisan topics, or for articles on climate change and environmental matters.

A look through 24 hours of posts here show the usual commenters posting the same political screeds uninformed by data or science. Where one or two try to include science, they get it ludicrously wrong.

On the bright side, the agreement was unanimously agreed to by all 195 nations present, and will soon enter into force upon ratification by at least 55 nations responsible for at least 55% of global greenhouse gas emissions. At the climate talks in Paris, not one country offered even a single objection based on any of the climate 'skeptics' worn-out talking points.

Even if the Paris agreement sets modest expectations for many of its signatories, at least it's a long overdue start towards a critical goal.
