“We are the last generation that can fight climate change. We have a duty to act.”
-Ban Ki-moon, U.N. Secretary GeneralOver the past century, the average temperature of the Earth has risen by 1.5°F. Over the next one hundred years, scientists are projecting another 0.5 to 8.6°F rise in the temperature. The cause of this temperature change is human activities that have released large amounts of carbon dioxide and other greenhouse gases (such as methane, nitrous oxide, and fluorinated gases) into the atmosphere. The majority of greenhouse gases come from burning fossil fuels to produce energy. Results of this global warming include:
- rising ocean temperatures,
- a more acidic the ocean,
- melting ice caps, and
- rising sea levels.
