From The New York Times:
Obama Pursuing Climate Accord in Lieu of Treaty
The Obama administration is working to forge a sweeping international climate change agreement to compel nations to cut their planet-warming fossil fuel emissions, but without ratification from Congress.
In preparation for this agreement, to be signed at a United Nations summit meeting in 2015 in Paris, the negotiators are meeting with diplomats from other countries to broker a deal to commit some of the world’s largest economies to enact laws to reduce their carbon pollution. But under the Constitution, a president may enter into a legally binding treaty only if it is approved by a two-thirds majority of the Senate.
To sidestep that requirement, President Obama’s climate negotiators are devising what they call a “politically binding” deal that would “name and shame” countries into cutting their emissions. The deal is likely to face strong objections from Republicans on Capitol Hill and from poor countries around the world, but negotiators say it may be the only realistic path.
One of the worst things that President Eisenhower did was to shoot down the Bricker Amendment:
Bricker Amendment
The Bricker Amendment is the collective name of a number of proposed amendments to the United States Constitution considered by the United States Senate in the 1950s. Each of these amendments would have placed restrictions on the scope and ratification of treaties and executive agreements entered into by the United States and are named for their sponsor, Senator John W. Bricker of Ohio, a conservative Republican.
Non-interventionism, the view that the United States should not become embroiled in foreign conflicts and world politics, has always been an element in American politics but was especially strong in the years following World War I. American entry into World War II temporarily suppressed non-interventionist sentiments, but they returned in the post-war years in response to America's new international role, particularly as a reaction to the new United Nations and its affiliated international organizations. Some feared the loss of American sovereignty to these transnational agencies, because of the Soviet Union's role in the spread of international Communism and the Cold War.
Frank E. Holman, president of the American Bar Association (ABA), called attention to state and Federal court decisions, notably Missouri v. Holland, which he claimed could give international treaties and agreements precedence over the United States Constitution and could be used by foreigners to threaten American liberties. Senator Bricker was influenced by the ABA's work and first introduced a constitutional amendment in 1951. With substantial popular support and the election of a Republican President and Congress in the elections of 1952, Bricker's plan seemed destined to be sent to the individual states for ratification.
The best-known version of the Bricker Amendment, considered by the Senate in 1953–54, declared that no treaty could be made by the United States that conflicted with the Constitution, was self-executing without the passage of separate enabling legislation through Congress, or which granted Congress legislative powers beyond those specified in the Constitution. It also limited the president's power to enter into executive agreements with foreign powers.
Bricker's proposal attracted broad bipartisan support and was a focal point of intra-party conflict between the administration of president Dwight D. Eisenhower and the Old Right faction of conservative Republican senators. Despite the initial support, the Bricker Amendment was blocked through the intervention of President Eisenhower and failed in the Senate by a single vote in 1954. Three years later the Supreme Court of the United States explicitly ruled in Reid v. Covert that the Bill of Rights cannot be abrogated by agreements with foreign powers. Nevertheless, Senator Bricker's ideas still have supporters, and new versions of his amendment have been reintroduced in Congress periodically.

If President Stompy-feet is able to get away with this, I am hoping that it will trigger a major shift in the way people vote. We really need some adults in the room now, especially in the Senate...
