Global warming
Overview
 
Global warming refers to the rising average temperature
Instrumental temperature record
The instrumental temperature record shows fluctuations of the temperature of the global land surface and oceans. This data is collected from several thousand meteorological stations, Antarctic research stations and satellite observations of sea-surface temperature. Currently, the longest-running...

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets...

's atmosphere and oceans and its projected continuation. In the last 100 years, Earth's average surface temperature increased by about 0.8 C-change with about two thirds of the increase occurring over just the last three decades. Warming of the climate system is unequivocal, and scientists are more than 90% certain most of it is caused by increasing concentrations of greenhouse gases
Greenhouse gas
A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone...

Deforestation
Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a nonforest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use....

Fossil fuel
Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms. The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years...

Global warming causing climate change may be the ultimate issue that unites us all.

Louise Burfitt-Dons,2008

"Why try to change the future when the present is so bleak"

Santa Bush 11/09/2007

"There's a better scientific consensus on this than on any issue I know -- except maybe Newton's second law of dynamics," said D. James Baker, administrator of the U.S. National Oceanic and Atmospheric Administration. "Man has reached the point where his impact on the climate can be as significant as nature's."

Warrick, Joby. “Consensus Emerges Earth Is Warming – Now What?” Washington Post 12 Nov. 1997: A01.

"The answer to global warming is in the abolition of private property and production for human need. A socialist world would place an enormous priority on alternative energy sources. This is what ecologically-minded socialists have been exploring for quite some time now."

Louis Proyect, Columbia University

‘Since global warming Eskimos now have twenty different words for water.’

John O'Farrell - This Is Your Life 2001

“If you asked me to name the three scariest threats facing the human race, I would give the same answer that most people would: nuclear war, global warming and Windows.”

Dave Barry

“While human-induced global warming is not going to turn present-day Earth into present-day Mars, global warming is dire enough that our most distinguished scientists recently concluded that as many as 1 million species on the planet could be extinct by 2050 if affairs do not change.”

Jay Inslee
