Energy and Climate - Science for Citizens in the Age of Global Warming (Audiobook)

While some argue that there's no "proof" that humans are warming the planet, certainly scientists across the world disagree. In his course "Energy and Climate: Science for Citizens of Global Warming," Professor Richard Wolfson provides the following arguments supporting serious global warming: 1. CO2 (carbon dioxide) has increased by over 30% since 1750. 2. CO2 is the dominant contributor to the greenhouse effect though other gases (methane, nitrous oxide, and CFCs) also contribute. 3. The US is responsible for about 20% of global CO2 emissions with a per capita emission of 20 tons per year. 4. By 2100, the atmospheric CO2 concentration is expected to double the pre-industrial level.
