Global Warming: For Experts Only

  1. Personally I think this Green Tax would be a good direction!

    Most likely, however, my guess is CO2 could be just part of the whole problem/issue?

  2. I am Not against reducing CO2 at all!

    I just think we should even do much more to protect the environment!

    Ensuring in the right direction?

    1. Contrary to your fantasy. Warming is not leading the next cycle up. Change in ocean temps is.
    how many times will it take before you read this peer reviewed paper or the many others we present which contradicts your 1980s viewpoint.


    2. And also contrary to your fantasy... temperature leads co2 down...

    Highlights
    ► Changes in global atmospheric CO2 are lagging 11–12 months behind changes in global sea surface temperature. ► Changes in global atmospheric CO2 are lagging 9.5–10 months behind changes in global air surface temperature. ► Changes in global atmospheric CO2are lagging about 9 months behind changes in global lower troposphere temperature. ► Changes in ocean temperatures explain a substantial part of the observed changes in atmospheric CO2 since January 1980. ► Changes in atmospheric CO2 are not tracking changes in human emissions.


    and now here is a long term chart. Again showing temperature leads co2 up and down.

    Q
    Industrial routes

    There are many technological methane production methods. Methane created from biomass in industrial plants via biological route is called biogas. A more synthetic method to produce methane is hydrogenating carbon dioxide through the Sabatier process. Methane is also a side product of the hydrogenation of carbon monoxide in the Fischer–Tropsch process, which is practiced on a large scale to produce longer-chain molecules than methane. Example of large-scale coal-to-methane gasification is the Great Plains Synfuels plant, started in 1984 in Beulah, North Dakota as a way to develop abundant local resources of low-grade lignite, a resource that is otherwise very hard to transport for its weight, ash content, low calorific value and propensity to spontaneous combustion during storage and transport.

    Methane as natural gas has been so abundant that synthetic production of it has been limited to special cases and as of 2016 covers only minor fraction of the methane used.
    UQ

    Methane is an important greenhouse gas with a global warming potential of 34 compared to CO2 over a 100-year period, and 72 over a 20-year period.[68][69][70]???

    Q
    Atmospheric methane

    Main article: Atmospheric methane
    Methane concentrations up to June 2017 (Mauna Loa)

    Methane is created near the Earth's surface, primarily by microorganisms by the process of methanogenesis. It is carried into the stratosphere by rising air in the tropics. Uncontrolled build-up of methane in the atmosphere is naturally checked – although human influence can upset this natural regulation – by methane's reaction with hydroxyl radicals formed from singlet oxygen atoms and with water vapor. It has a net lifetime of about 10 years,[66] and is primarily removed by conversion to carbon dioxide and water.

    In addition, there is a large (but unknown) amount of methane in methane clathrates in the ocean floors as well as the Earth's crust.

    In 2010, methane levels in the Arctic were measured at 1850 nmol/mol, a level over twice as high as at any time in the 400,000 years prior to the industrial revolution. Historically, methane concentrations in the world's atmosphere have ranged between 300 and 400 nmol/mol during glacial periods commonly known as ice ages, and between 600 and 700 nmol/mol during the warm interglacial periods. Recent research suggests that the Earth's oceans are a potentially important new source of Arctic methane.[67]

    Methane is an important greenhouse gas with a global warming potential of 34 compared to CO2 over a 100-year period, and 72 over a 20-year period.[68][69][70]

    The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases (these gases don't include water vapor which is by far the largest component of the greenhouse effect).[6]

  10. So it should be easy to be easy to find ONE publishing scientist that denies man made global warming.

    The consensus is essentially 100%. https://climate.nasa.gov/scientific-consensus/


    Still waiting.
