    Climate Change Indicators in the United States
    http://www.epa.gov/climatechange/science/indicators/download.html
    The information on this website is drawn from the second edition of EPA's Climate Change Indicators in the United States (PDF) (84 pp, 18.2MB), published in 2012. This report presents 26 indicators, each describing trends related to the causes and effects of climate change. It focuses primarily on the United States, but in some cases global trends are presented to provide context or a basis for comparison. The online version will be updated periodically as new data become available, and thus may differ from the printed version available below.
    2012 Edition
    Full Report (PDF) (84 pp, 18.2MB)
    Technical Documentation (PDF) (180 pp, 2.5MB)
    Summary Brochure (PDF) (4 pp, 6.4MB)
    Individual Sections
    · Front cover, table of contents, and acknowledgments (PDF) (4 pp, 534K)
    · Introduction (PDF) (3 pp, 2.9MB)
    · Summary of Key Points (PDF) (4 pp, 391K)
    · Greenhouse Gases (PDF) (12 pp, 3.0MB)
    · Weather and Climate (PDF) (14 pp, 2.7MB)

    The 2012 edition includes three new indicators and provides updates and revisions to several existing indicators since the 2010 edition.
    2010 Edition
    The first edition of EPA's Climate Change Indicators in the United States report is available below.
    Full Report (PDF) (80 pp, 13.2MB)

    More horse crap from the mentally deficient. I love the section where they claim that CO2 can remain for thousands of years. Provable and laughably wrong. Typical of a propagandist organisation that no longer cares about its original remit.

    Your reading "ability" seems to explain the difficulty you have understanding science.

    From source - "* Carbon dioxide’s lifetime is poorly defined because the gas is not destroyed over time, but instead moves among different parts of the ocean–atmosphere–land system. Some of the excess carbon dioxide will be absorbed quickly (for example, by the ocean surface), but some will remain in the atmosphere for thousands of years, due in part to the very slow process by which carbon is transferred to ocean sediments."

    Emissions of CO2 from fossil fuel use and from the effects of land use change on plant and soil carbon are the primary sources of increased atmospheric CO2. Since 1750, it is estimated that about 2/3rds of anthropogenic CO2 emissions have come from fossil fuel burning and about 1/3rd from land use change. About 45% of this CO2 has remained in the atmosphere, while about 30% has been taken up by the oceans and the remainder has been taken up by the terrestrial biosphere. About half of a CO2 pulse to the atmosphere is removed over a time scale of 30 years; a further 30% is removed within a few centuries; and the remaining 20% will typically stay in the atmosphere for many thousands of years. {7.3}

    I'll counter with this....


    "Where, then, is all the carbon dioxide from fossil fuels that is not in the atmosphere [35]? Geoscientists have long known that most atmospheric carbon dioxide cycles through the upper ocean every 5-10 years [36]. Some new carbon dioxide, with estimates of 20-35 percent of new emissions from all sources [37], cycles down into cold deep waters where its solubility is greatest and where recycling times slow to hundreds or thousands of years [38]. Some carbon dioxide goes into organic and inorganic deposition of calcium carbonate that ends up in the sediments on the ocean floor. Life processes have sequestered significant carbon in new biomass, particularly in phytoplankton [39] and non-edible hydrocarbons [40] in the oceans. Accelerated rock weathering also occurs [41] with the calcium released precipitated as carbonate in soils and ocean sediments."

    Even your very own high priests website admits it....then trys to obfuscate that with irrelevant drivel...backed up by zero scientific observational data.

    Individual carbon dioxide molecules have a short life time of around 5 years in the atmosphere. However, when they leave the atmosphere, they're simply swapping places with carbon dioxide in the ocean. The final amount of extra CO2 that remains in the atmosphere stays there on a time scale of centuries.

    Really dumb, Walleyes. Under normal conditions the ocean both emits and absorbs CO2. At about the same rate. Because of our burning of fossil fuels, it is now absorbing more than it emits. And that is showing up in the acidification of the ocean.

    And, once again, you are using blog sites to counter sites from scientific sources. Obese junkies are fine to listen to on the radio, and cite in conversations with drunken and ignorant buddies, they get you laughed out of the room in a scientific conversation.

    And a sentence or two from your own post "Individual carbon molecules have a short lifetime of around five years in the atmsphere. However, when they leave the atmosphere, they are simply swapping places with carbon dioxide in the ocean. The final amount of CO2 in the atmosphere remains the same, the extra CO2 remains there for centuries".

    When you can't point to a single repeatable experiment that demonstrates how a 100ppm increase in CO2 raises temperature a few degrees, you have to post a whole lot of links and sources and other irrelevant data

    Prove it. My theory that the current CO2 increase is based on the warming from the MWP is supported by actual evidence from the Vostock ice core data, unlike your theory which is based on computer fantasies.

    Your "theory" about the source of the current CO2 increase is as ignorant and crackpot as all of your delusional fantasies, you poor brain damaged retard. Isotope analysis proves that most of the excess CO2 in the atmosphere is coming from fossil fuels.

    Actually it's not. The Vostock ice core data shows an 800 year lag from warming to an increase in CO2. Interestingly enough it has been 800 years since the end of the MWP. But that would be a fact and we all know you don't "do" facts.

    Actually it is. Your "theory" actually is ignorant, delusional, crackpot nonsense, and exactly what we've all come to expect from you.



    As you make very obvious, you have no freaking idea what "fact" actually means. You also have no freaking idea what any of the science means because you a brainwashed, delusional and very ignorant anti-science retard. Let's compare you and your ignorance-based crackpot nonsense to an actual expert on this subject and the well researched, observationally-based, sound science that he produces.

    How do we know that recent CO2 increases are due to human activities?
