An unexpected increase in the concentration of carbon dioxide in the atmosphere

Carbon dioxide levels are rising 35% faster than previously predicted since 2000

Carbon dioxide levels in the atmosphere have increased at a rate about 35% faster than predicted since 2000. Scientists from around the world have discovered that the inefficient use of fossil fuels has increased the level of carbon dioxide by 17%. The other 18% comes from the reduction in the natural ability of the earth and oceans to absorb the carbon dioxide gas from the atmosphere. The research was funded by international agencies and entities from Australia and Europe.

The alarming study is published a few days after the Nobel Peace Prize committee awarded the prize to the work dealing with global warming To former US Vice President Al Gore and the panel monitoring global warming. According to the study, the rate of carbon dioxide emissions as a result of burning fuels increased from 7 billion tons per year in 2000 to 8.4 billion tons in 2006. The growth rate increased from 1.3 percent between the years 1990-1999 to 3.3% per year in the years 2000-2006. added the researchers.
The rate of carbon dioxide emissions was 2006% higher in 35 than in 1990, a faster rate than expected, says Joseph G. Canadell of the British Commonwealth Institute for Research and Development, in the Tuesday issue of the journal PNAS.
The increasing use of fossil fuels by the industry plus the decrease in the ability to absorb carbon dioxide by the oceans and the earth, were among the reasons for the increase.
"In addition to the increase in the human population and the growth in the standard of living, we know that two significant factors contributing to the increase in carbon dioxide in the atmosphere arise from the slowing down of nature's ability to absorb this chemical substance from the air," says Kandel, director of the global carbon project at the research institute.
The changes in the strength of the "carbon cycle" (from its emission into the atmosphere to its decomposition by the plants) are greater than expected, and therefore its effect on the climate is earlier than expected," write the researchers.
Kevin Turnbreth, a climate expert at the National Center for Atmospheric Research in Boulder, Colorado, is concerned that carbon dioxide concentrations are rising despite the Kyoto agreement that regulated the reduction of carbon emissions in rich countries, and the rate of increase is even increasing. Alan Roebuck, assistant director at the Center for Environmental Sensing at Rutgers University added: "What is really shocking is the reduction in the rate of decomposition capacity of the oceans, meaning that the oceans can now absorb less carbon dioxide removed from the air. "The reduction was directly due to warming and not as the researchers claim - indirectly due to a change in the direction and strength of the currents - it's like the difference between warm coke and cold coke" said Robock. The two researchers were interviewed by the AP news agency as experts and were not partners in the research.

However, while everyone is focusing on carbon, Turnberth says that the rate of methane gas has decreased, so that overall the level of greenhouse gases has increased at a more moderate rate than the rate of increase in carbon emissions. In addition, there are other pollutants whose effect on the atmosphere is manifested in cooling. Whereas Rock claims against the study that it examines too short a period of time to be able to discover trends" however according to him, the results seem logical, and most of the article talks about long-term trends.

  1. Why is there no decline despite Kyoto?
    Because the stupid Bush did not sign!!
    And so the richest nation in the world continues to destroy the future of all of us!!
    When the sea level rises, the residents of Manhattan will have nowhere to run, but what will happen to the residents of Calcutta??
