For many years, researchers agreed that climate change was triggered by what they called "greenhouse gases," with carbon dioxide from burning of fossil fuels such as coal, oil, and gas, playing the biggest role. However, new research suggests fossil fuel burning may not be as important in the mechanics of climate change as previously thought. NASA funded research by Dr. James Hansen of the Goddard Institute for Space Studies, New York, NY, and his colleagues, suggests that climate change in recent decades has been mainly caused by air pollution containing non-carbon dioxide greenhouse gases, particularly tropospheric ozone, methane, chlorofluorocarbons (CFCs), and black carbon (soot) particles. Since 1975, global surface temperatures have increased by about 0.9 degrees Fahrenheit, a trend that has taken global temperatures to their highest level in the past millennium.
