Climate Change: Frequently Asked Questions about the 2015 Paris Agreement. Congressional Research Service, Library of Congress. Jane A. Leggett and Richard K. Lattan. September 1, 2016.
Experts broadly agree that stabilizing greenhouse gas (GHG) concentrations in the atmosphere to avoid dangerous GHG–induced climate change could be accomplished only with concerted efforts by all large emitting nations. Toward this purpose, delegations of 195 nations adopted the Paris Agreement (PA) on December 12, 2015. The PA outlines goals and a structure for international cooperation to slow climate change and mitigate its impacts over decades to come. Heads of state and ministers from more than 175 governments signed the PA, a record for a single day. Signature generally indicates that a nation state intends to be bound by the agreement, and it initiates the process by which a prospective Party follows its domestic procedures to ratify, accept, approve, or accede to the agreement.
