Atmospheric CO2 At New High

with 4 comments

Concentrations of carbon dioxide have risen to 390 parts per million (ppm) from 388 a year ago.

“Levels are at a new high,” said Kim Holmen, research director of the Norwegian Polar Institute, which oversees the Zeppelin measuring station on the Arctic archipelago of Svalbard about 1,200 km from the North Pole ……. more

  1. From http://www.eia.doe.gov/neic/press/press271.html ;

    ‘Worldwide marketed energy consumption is projected to grow by 71 percent between 2003 and 2030, according to the reference case projection from the International Energy Outlook 2006 (IEO2006) released today by the Energy Information Administration (EIA). The IEO2006 shows the strongest energy consumption growth in developing countries outside the Organization for Economic Cooperation and Development (OECD), especially non-OECD Asia (including China and India), where robust economic growth drives the increase in energy use. Energy use in non-OECD Asia nearly triples over the projection period’.

  2. Or, between 1994 and 2004 emissions from the consumption of petroleum increased by 1.7 billion metric tons of carbon dioxide, or 18.1 percent, rising from 9.2 to 10.8 billion metric tons.

    The United States was the largest producer of carbon dioxide from the consumption of petroleum in 2004 and accounted for 24 percent of the world total. China was the second largest producer, followed by Japan, Russia, and Germany, and together these four countries accounted for an additional 20 percent.

    In 2004, the consumption of petroleum was the world’s primary source of carbon dioxide emissions from the consumption and flaring of fossil fuels, accounting for 40.1 percent of the total.

  3. Hi Matt,

    Which raises the question of last year only being the 5th hottest on record? According to theory, shouldn’t every year be hotter than the last as CO2 levels rise?

  4. Grit:
    No. Temperatures are rising, but not in a straight line. Nothing is that simple. Natural variation (as the deniers love to point out) comes from phenomena like El Nin~o and solar activity. This variation makes it meaningless to compare any given year with the previous year, but looking at the bigger picture we can nevertheless see clear trends towards higher temperatures.
