Green Alert: Our Warming Planet

The average temperature of the Earth has risen by up to 0.6 degrees C over the last 100 years. This has caused extreme weather events, from hurricanes and floods to heat waves and drought, which spread disease, destroy property and affect the natural ecosystems of plants and animals. Our Warming Planet traces the causes of global warming and studies its impact on the Earth. Topical examples look at how it has affected different regions, and the countries, organizations and individuals working to prevent further damage.
