Bush has said he believes that global warming is real[158] and has noted that it is a serious problem, but he asserted there is a "debate over whether it's man-made or naturally caused".[159] The Bush Administration's stance on global warming remained controversial in the scientific and environmental communities. Critics have alleged that the administration[160] misinformed the public and did not do enough to reduce carbon emissions and deter global warming.[161]

Energy policies
In his 2006 State of the Union Address, Bush declared, "America is addicted to oil" and announced his Advanced Energy Initiative to increase energy development research.[162]

In his 2007 State of the Union Address, Bush renewed his pledge to work toward diminished reliance on foreign oil by reducing fossil fuel consumption and increasing alternative fuel production.[163] Amid high gasoline prices in 2008, Bush lifted a ban on offshore drilling.[164] However, the move was largely symbolic because there was still a federal law banning offshore drilling.
