The term climate change is used to refer to changes in the Earth 's global climate or regional climates. It describes changes in the variability or average state of the atmosphere - or average weather - over any time scale from decades to millions of years. These changes can come from internal processes, be driven by external forces or, most recently, be caused by human activities. From Wikipedia

Some sites to help in this effort:

• EPA: Global Warming for Educators
  EPA's Global Warming Site contains a wealth of materials that educators and outreach professionals can use in presentations and classroom activities on climate change science, potential impacts, and mitigation options.

• CNN.com Specials: Changing Earth
  Is global warming really a threat? Yes, respond most scientists, but only recently have they been able to approach a basic agreement about changing climate. Learn more here!

• Global Learning and Observations to Benefit the Environment (GLOBE)
  GLOBE is a worldwide network of students, teachers, and scientists working together to study and understand the global environment. Students and teachers from over 6,500 schools in more than 80 countries are working with research scientists to learn more about our planet. GLOBE students make environmental observations at or near their schools and report their data through the Internet.

• NOAA: Exploring Weather & Climate Change Through the Powers of 10
  Designed as an online tool allowing users to examine climate change and variability at different time scales, the Climate TimeLine has been developed through a CIRES Innovative Research Grant through the NOAA Paleoclimatology Program which is part of the National Climatic Data Center.

Watch live images of Mei Xiang, a giant panda, and her newborn cub at the National Zoo (http://nationalzoo.si.edu) in Washington, D.C. The cub was born at 3:41 a.m. on Saturday, July 9, 2005. Mother and cub appear to be doing just fine. Zoo keepers were happy to see Mei Xiang cradling and cuddling her cub only two minutes after its birth.

Enjoy!
