troposphere, definition of

Carbon Footprint refers to the the total greenhouse gas emissions that result from a person, organization, product or service over a given time.

It tends to act as an umbrella term for any attempt to measure greenhouse gas emissions and as a result can refer to simply the emissions that result from a single activity, such as flying; the emissions that result from an organization or building over the course of a year; or the full lifetime emissions of a product or organization, including emissions from the supply chain or disposal of resources.

While carbon footprints colloquially refer to the amount of CO2 emitted, the UK Carbon Trust endorses a wider definition and considers all six of the Kyoto Protocol greenhouse gases - Carbon dioxide, Methane, Nitrous oxide, Hydro fluorocarbons, Perfluorocarbons, and Sulfur hexafluoride - when measuring a carbon footprint.

• 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”.

  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...
