Al Gore was Vice President of the United States from 1993 to 2001 and won the popular vote in the 2000 Presidential Election. He served as a Senator and Representative for many years prior to becoming VP. As a politician, he advocated for many environmental initiatives, but many were unable to be fully implemented. After losing the presidential race, he focused his energy and intellect on climate change, one of his primary concerns.

As an environmental activist, Gore earned the Nobel Peace Prize in 2007, among many other honors. He launched the Generation Investment Management company and serves as its chair, founded the Alliance for Climate Protection, helped with Live Earth benefit concerts, and became a vegan. He also wrote An Inconvenient Truth: The Planetary Emergency of Global Warming and What We Can Do About It (2006), Our Choice (2009), and The Future: Six Drivers of Climate Change (2013).
