Climate negotiators are meeting in Durban, South Africa beginning from November 28-December 9 to discuss the planet's changing climate.
The first decade of this century was the hottest on record. Polar ice is melting. Global sea levels are rising. And the vast majority of scientists attribute the changes to greenhouse gases, both natural from water vapor and man-made from burning fossil fuels, that trap heat in the lower atmosphere. "Since roughly the 1850s or so, we've seen an increase globally of about eight-tenths of a degree Celsius, so that's roughly 1.4 degrees Fahrenheit," said Todd Sanford, a climate scientist at the Union of Concerned Scientists in Washington. A one-degree difference is not noticeable in daily temperatures, but a one-degree change in global average temperature is significant.
