Carbon Dioxide In Earth's Atmosphere - Past Variation
... The most direct method for measuring atmospheric carbon dioxide concentrations for periods before direct sampling is to measure bubbles of air (fluid or gas inclusions) trapped in the Antarctic or Greenland ice sheets ... come from a variety of Antarctic cores and indicate that atmospheric CO2 levels were about 260–280 ppmv immediately before industrial emissions began and did not ... During this time, the atmospheric carbon dioxide concentration has varied between 180–210 ppm during ice ages, increasing to 280–300 ppm during ...
Roger Revelle - Career - Global Warming
... under Revelle's directorship, SIO participated in and later became the principal center for the Atmospheric Carbon Dioxide Program. 1956, Charles David Keeling joined the SIO staff to head the program, and began measurements of atmospheric carbon dioxide at the Mauna Loa Observatory on Mauna Loa, Hawaii, and in Antarctica ... a paper with Hans Suess that suggested that the Earth's oceans would absorb excess carbon dioxide generated by humanity at a much slower rate than previously predicted by geoscientists, thereby suggesting that human ...
Yedoma
... Yedoma is an organic-rich (about 2% carbon by mass) Pleistocene-age loess permafrost with ice content of 50–90% by volume ... The amount of carbon trapped in this type of permafrost is much more prevalent than originally thought and may be about 500 Gt, that is almost 100 times the amount of carbon released into the air each year ... Thawing yedoma is a significant source of atmospheric methane (about 4 Tg of CH4 per year) ...

The film asserts that records of atmospheric CO2 levels since 1940 show a continuing increase, but during this period, global temperature decreased until 1975, and has increased ... over 100 years) behind temperature increases during glacial terminations Relationship between atmospheric carbon dioxide levels and temperature change ...

Famous quotes containing the word atmospheric:

    Nor has science sufficient humanity, so long as the naturalist overlooks the wonderful congruity which subsists between man and the world; of which he is lord, not because he is the most subtile inhabitant, but because he is its head and heart, and finds something of himself in every great and small thing, in every mountain stratum, in every new law of color, fact of astronomy, or atmospheric influence which observation or analysis lay open.
    Ralph Waldo Emerson (1803–1882)
