Troposphere, definition of

The lowest layer of the atmosphere and contains about 95 percent of the mass of air in the Earth's atmosphere. The troposphere extends from the Earth's surface up to about 10 to 15 kilometers. All weather processes take place in the troposphere. Ozone that is formed in the troposphere plays a significant role in both the greenhouse gas effect and urban smog.

• Is Warming Accelerating in the Troposphere?
  ...the new NOAA data do not support a claim that warming in the troposphere has undergone a statistically-significant change in trend.
• The Cooling Side of Greenhouse Gases
  Most people are unaware that the greenhouse gases CO2 and H2O, both warm & cool our planet. When I mention that CO2 has a cooling effect, I’m amazed by the hateful tirades from paranoid people who dismiss scientific truth as “dangerous misinformation”.
• Scientists have a plan to cool the Earth with a sprinkle of salt
  Could salt help soothe our climate woes? Senior scientist Robert Nelson of the Planetary Science Institute seems to think so. At a recent Lunar and Planetary Science Conference in Texas, Nelson suggested that sprinkling salt above clouds could hold off...

• UAH Global temperature, down slightly, “the pause” continues
  UAH v5.6 Global Temperature Update for Nov. 2013: +0.19 deg. C by Roy W. Spencer, Ph. D. The Version 5.6 global average lower tropospheric temperature (LT) anomaly for November, 2013 is +0.19 deg. C, down from +0.29 deg. C in … Continue reading...
• Chemtrails or Contrails? Another Alarmist Issue Without Scientific Context
  NOTE: like with the essay Saturday about isotasy/glacial rebound being a myth, I don’t think the chemtrails idea has any merit whatsoever. Dr. Tim Ball points out more bad science – chemtrails, which are really just contrails, and which has...
• UAH global temperature – up .06C – not much change
  UAH Global Temperature Update for August, 2012: +0.34 deg. C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for August (+0.34 °C) was up from July 2012 (+0.28 °C): Here are the monthly departures from the 30-year …...
• Arctic temperature anomaly uncertainties
  Dr. Roger Pielke Sr. writes of a new paper which suggest that Arctic temperaturehas even greater uncertainty problems. He writes (excerpts) New Paper “A Multi-Data Set Comparison Of The Vertical Structure Of Temperature Variability And Change Over The...
• May UAH Global Temperature – unchanged
  UAH Global Temperature Update for May 2012: +0.29°C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for May 2012 (+0.29 °C) changed little from April (+0.30 °C), with some warming to near-average temperatures in the tropics...
