What crap ! !   Does that idiot think that people are not capable of

doing a little research on the findings of past climate and

atmospheric CO2 levels on Earth ? ?

Even at CO2 levels of 7000ppm, the Earth never got a higher average

temperature than 22 degrees C at the maximum.  Let’s be generous and

say it got as high as 23 degrees C average global temperature.

(Unlikely)

  The reason is… the law of diminishing returns.

    I guess Jaccard and his pal Gore would want that information kept

very quiet.

    Also, please don’t forget….  being about 25,500,000 miles

    (41,000,000 kilometers) closer to the Sun than the Earth,  perhaps

    that would also make Venus a degree or two warmer… don’t you

    think ? ?  LOL

    Ahh, but Mars has an atmosphere of almost 100% CO2. Although
    it is very thin, it still has a higher pressure than the CO2
    partial pressure on earth. And yet, the average temperature
    of Mars is slightly colder than it’s moons, which have no
    atmosphere.

    Venus is interesting too. It’s atmospheric pressure is far
    higher than earth’s. For a couple of reasons. One is that
    with an atmosphere of almost 100% CO2, CO2 is about 70%
    heavier than the average molecular weight of earth air. But
    that is only a small part of the story, and doesn’t come
    close to accounting for the crushing pressures at the
    surface. The Venusian atmosphere is much higher than
    earth’s. To the point where about 50km up it has the same
    pressure as the earth’s atmosphere at sea level. At 50km,
    the earth’s atmosphere is barely present. Interestingly, at
    that height on Venus, the temperature is almost the same as
    earth’s sea level temperature.

    So it would appear that the greenhouse effect has more to do
    with the density of the atmosphere, than the constituent
    gases of the atmosphere.

    Arctic permafrost leaking methane at record levels, figures show

    http://www.guardian.co.uk/environment/2010/jan/14/arctic-permafrost-m

    Scientists have recorded a massive spike in the amount of a powerful

    greenhouse gas seeping from Arctic permafrost, in a discovery that

    highlights the risks of a dangerous climate tipping point.

    Experts say methane emissions from the Arctic have risen by almost

    one-third in just five years, and that sharply rising temperatures are

    to blame.

    The discovery follows a string of reports from the region in recent

    years that previously frozen boggy soils are melting and releasing

    methane in greater quantities. Such Arctic soils currently lock away

    billions of tonnes of methane, a far more potent greenhouse gas than

    carbon dioxide, leading some scientists to describe melting permafrost

    as a ticking time bomb that could overwhelm efforts to tackle climate

    change.

    They fear the warming caused by increased methane emissions will

    itself release yet more methane and lock the region into a destructive

    cycle that forces temperatures to rise faster than predicted.

    Paul Palmer, a scientist at Edinburgh University who worked on the new

    study, said: "High latitude wetlands are currently only a small source

    of methane but for these emissions to increase by a third in just five

    years is very significant. It shows that even a relatively small

    amount of warming can cause a large increase in the amount of methane

    emissions."

    Global warming is occuring twice as fast in the Arctic than anywhere

    else on Earth. Some regions have already warmed by 2.5C, and

    temperatures there are projected to increase by more than 10C by 2100

    if carbon emissions continue to rise at current rates.

    Palmer said: "This study does not show the Arctic has passed a tipping

    point, but it should open people’s eyes. It shows there is a positive

    feedback and that higher temperatures bring higher emissions and

    faster warming."

    The change in the Arctic is enough to explain a recent increase in

    global methane levels in the atmosphere, he said. Global levels have

    risen steadily since 2007, after a decade or so holding steady.

    The new study, published in the journal Science, shows that methane

    emissions from the Arctic increased by 31% from 2003-07. The increase

    represents about 1m extra tonnes of methane each year. Palmer

    cautioned that the five-year increase was too short to call a

    definitive trend.

    The findings are part of a wider study of methane emissions from

    global wetlands, such as paddy fields, marshes and bogs. To identify

    where methane was released, the researchers combined methane levels in

    the atmosphere with surface temperature changes. They did not measure

    methane emissions directly, but used satellite measurements of

    variations in groundwater depth, which alter the way bacteria break

    down organic matter to release or consume methane.

    They found that just over half of all methane emissions came from the

    tropics, with some 20m tonnes released from the Amazon river basin

    each year, and 26m tonnes from the Congo basin. Rice paddy fields

    across China and south and south-east Asia produced just under

    one-third of global methane, some 33m tonnes. Just 2% of global

    methane comes from Arctic latitudes, the study found, though the

    region showed the largest increases. The 31% rise in methane emissions

    there from 2003-07 was enough to help lift the global average increase

    to 7%.

    Palmer said: "Our study reinforces the idea that satellites can

    pinpoint changes in the amount of greenhouse gases emitted from a

    particular place on earth. This opens the door to quantifying

    greenhouse gas emissions made from a variety of natural and man-made

    sources."

    Palmer said it was a "disgrace" that so few satellites were launched

    to monitor levels of greenhouse gases such as carbon dioxide and

    methane. He said it was unclear whether the team would be able to

    continue the methane monitoring in future. The pair of satellites used

    to analyse water, known as Grace, are already over their expected

    mission life time, while a European version launched last year, called

    Goce, is scheduled to fly for less than two years.

    The new study follows repeated warnings that even modest levels of

    global warming could trigger huge increases in methane release from

    permafrost. Phillipe Ciais, a researcher with the Laboratory for

    Climate Sciences and the Environment in Gif-sur-Yvette, France, told a

    scientific meeting in Copenhagen last March that billions of tonnes

    could be released by just a 2C average global rise.

    More on methane

    While carbon dioxide gets most of the attention in the global warming

    debate, methane is pound-for-pound a more potent greenhouse gas,

    capable of trapping some 20 times more heat than CO2. Although methane

    is present in much lower quantities in the atmosphere, its potency

    makes it responsible for about one-fifth of man-made warming.

    The gas is found in natural gas deposits and is generated naturally by

    bacteria that break down organic matter, such as in the guts of farm

    animal. About two-thirds of global methane comes from man-made

    sources, and levels have more than doubled since the industrial

    revolution.

    Unlike carbon dioxide, methane lasts only a decade or so in the

    atmosphere, which has led some experts to call for greater attention

    to curbs on its production. Reductions in methane emissions could

    bring faster results in the fight against climate change, they say.
