Global Warming

Our energy-intensive and fossil fuel dependent lifestyles have led to a dramatic growth in greenhouse gas emissions.  This has resulted in global temperatures rising faster than ever recorded in human history.  The planet has already warmed by almost 1°C since 1900, most of this in the last 25 years.  If action is not taken to cut at least 60% of current global greenhouse gas emissions within 20 years, carbon dioxide concentration levels in the atmosphere will reach 550-600 particles per million, and the planet will warm a further 2-3°C before 2050.
