When the 2007 Nobel Peace Prize went to former Vice President Al Gore and an international scientific body that warned of serious consequences if Earth's temperatures continue to rise, the award underscored the international concern about the Earth's changing climate. Most scientists agree that global warming is a serious threat, and that human beings contribute to it by burning carbon-containing fuels such as oil and coal; and the international community has moved to limit carbon emissions. However, some scientists dispute the link between greenhouse gases and global warming. Many prominent Americans, including members of Congress, object to putting limits on carbon emissions, arguing that the evidence of warming is still uncertain and cutting emissions would cripple the economy while doing little to curb global warming. ""Environmental Regulations and Global Warming"" discusses the debate about whether and how our government should act to protect the Earth's climate.
