It's always fascinating to see this type of blatant error in AP articles. It happens with such a frequency and such specificity that it cannot be unintentional.
The United States is no longer bound by Kyoto, which the Bush administration rejected after taking office in 2001.
BUZZ!!! Wrong. Let's fact check it from Wikipedia.
On July 25, 1997, before the Kyoto Protocol was finalized (although it had been fully negotiated, and a penultimate draft was finished), the U.S. Senate unanimously passed by a 95â€“0 vote the Byrd-Hagel Resolution (S. Res. 98), which stated the sense of the Senate was that the United States should not be a signatory to any protocol that did not include binding targets and timetables for developing as well as industrialized nations or "would result in serious harm to the economy of the United States". On November 12, 1998, Vice President Al Gore symbolically signed the protocol. Both Gore and Senator Joseph Lieberman indicated that the protocol would not be acted upon in the Senate until there was participation by the developing nations. The Clinton Administration never submitted the protocol to the Senate for ratification.
This world is tough enough to understand without this type of "journalism".
