Who else signed Kyoto? I thought it was only one country.
And every single Democrat voted AGAINST Kyoto when it came up for a vote during Clinton's term.
For most countries Kyoto is meaningless and does not change anything - it only truly affects a handful of developed countries.
Countries like India and Nigeria and China and Brazil are exempt from its requirements.
The entire treaty is basically designed to punish America for being economically successful and that's why America refuses to sign it.
