Climate Change

What Is Climate Change

A change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. The earths climate has changes very much. Within the last 650,000 years years there have been seven cycles of glacial advance and retreat. The end of the last ice age 7,000 years ago was the start of the modern climate era.

Results of Climate Change?

Global climate change already has had noticeable affects. Ice on lakes and rivers melts sooner, glaciers have shrunken and diapered, trees are flowering sooner, and plant and animal ranges have moved. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.
