Jet Propulsion Laboratory, California Institute of Technology Climate Change Symposium October 16, 2010 The Natural Greenhouse Effect is Good It warms the Earth by about 50 degrees F
- Carbon dioxide controls Earths temperature - Climate Change: Vital . . .
Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide

Taking the pulse of greenhouse gases Arctic wintertime sea ice extent is among lowest on record Scientists assess potential for super greenhouse effect in Earth's tropics NASA powers on new instrument staring at the Sun February 2018 was sixth warmest February on record How cloud data are improving weather forecasts
- Warm Up – Climate Change: Vital Signs of the Planet
The greenhouse effect is a naturally occurring physical process that warms the Earth's surface with energy from the atmosphere Without the effect, Earth's average surface temperature would be well below freezing

The Greenhouse Effect Correlation Between CO2 and Temperature Historic Carbon Dioxide Increase Average preindustrial concentration: 280 ppmv Today: ~385 ppmv * 50 year Record of Precise Ground Measurements * http: www esrl noaa gov gmd ccgg trends co2_data_mlo html Per Capita Carbon Dioxide Emissions Tans, ICDC8, 2009 * Carbon Dioxide is Part
- Carbon – Climate Change: Vital Signs of the Planet
In 1856, Eunice Foote discovered that carbon dioxide (CO₂) and water vapor in Earth's atmosphere trap escaping infrared (heat) radiation, acting like a blanket to keep the surface layers warm (the greenhouse effect)
- Earths Freshwater Future: Extremes of Flood and Drought
As Earth’s atmosphere warms due to greenhouse gases and NASA's satellite data record continues to get longer and more detailed, scientists are studying how climate change is affecting the distribution of water, such as in droughts and floods
- Can Climate Affect Earthquakes, Or Are the Connections Shaky?
“We’ve seen that relatively small stress changes due to climate-like forcings can effect microseismicity,” he said “A lot of small fractures in Earth’s crust are unstable We see also that tides can cause faint Earth tremors known as microseisms
