April Will Be First Month With CO2 Levels Above 400 PPM

Climate Central: “April will be the first time in human history where levels of atmospheric carbon dioxide were higher than 400 parts per million for an entire month, one scientist who monitors the levels said. And they could stay above that mark into July.”

“Carbon dioxide concentrations, as measured at a site atop Hawaii’s Mauna Loa volcano since 1958, surpassed the 400 ppm mark for the first time in recorded history on May 9, 2013. While the particular mark is symbolic, it serves to show how far concentrations have risen from their pre-industrial levels of 280 ppm as fossil fuels such as coal and oil have continued to be burned.”

      You were supposed to learn the connection between increased CO2 and climate change in grade school.

    Where is your evidence that the data is manufactured? Please don’t reply with any non-sense regarding the hacked e-mails, those were already shown to have been completely taken out of context and not to support the claims that climate-deniers have wanted them to. Also, where is your evidence that that CO2 emissions do not contribute to climate change. Typing in all-caps does not make you any more correct in your assertions. Putting scare quotes around climate change does not negate the fact that it is indeed happening. Finally, wishing away the problem will not make it go away. Climate change is real, human activity is contributing to it, and unless if something is done immediately to counteract, it could lead to severe to possibly catastrophic consequences to us.
    So in closing, please grow up.

      Who needs facts when you have ALL CAPS

  • Carbon Dioxide isn’t just an inert substance that hangs about in the atmosphere. It is in fact the sole source of carbon used by plants in the construction of new tissue.

    The carbohydrates that people eat from plant sources such as wheat, corn, etc, etc, all get their carbon component from thin air, literally. Next time you eat a sandwich, you’re munching down carbon that came straight from a car’s tailpipe. Then there are the countless plant species that human beings do not eat or otherwise consume. These too soak up carbon as fast as they can get it.

    I find it hard to believe that CO2 levels would gradually increase over time as this graph shows when the world is literally covered with organisms that continually extract it from the atmosphere.

    Satellite image of the earth over the past few decades have shown that the earth is actually “greening.” That is to say, the level of vegetation has increased. All the free carbon we are extracting from carbon sinks (aka fossil fuels) undoubtedly has something to do with this.

    Seems that old gas guzzler is actually “greener” than a Prius in that its waste product actually acts as fertilizer.

      Point is the organisms cannot keep up anymore as we (Humans) are putting so much more into our atmosphere…

      • That would be true if there were some limiting factor that prevented plants from using CO2 to build new tissue. There just isn’t. As I said before, satellite images of the earth have shown an increase in plant life over the past few decades. We have not reached the saturation point for plant life on planet earth, not even close.

          your talking about an amount of carbon the earth took many millions of years, and many many plant generations to bury.

          The “greening” is a red herring that is mostly not real, and even the increase in the arctic that is doesn’t come even close to slowing down the rise we are creating.

    • moderatesunite

      These are actual measurements, verified by multiple people, and groups around the world, there is no doubt that CO2 has increased in this manner.

      Natural absorption of CO2 by plants, and emission by animals is in a natural balance, but much of the carbon that was once in the atmosphere was buried when plants, animals, plankton etc. died after absorbing carbon through exactly the process you describe and where buried. By burning peat, coal, oil, and natural Gas we are dumping all the carbon that the earth took many, many generations of plants to bury into the air at once, much more than they can absorb,

      at the same time we are losing 12-15 million hectares of forest every year. reducing one of the most effective ways the planet has to absorb the carbon.

      As for “greening” observed that has several explanations

      A misinterpretation of satellite data based on how light reflects during the dry season in the Amazon.

      Is the most common reason given

      If you are looking at certain times of year you might notice somewhat more vegetation in the arctic and tundra zones due the warming planet and retreating ice sheets.


      That’s a reason to be more concerned not less as it is a sign the world temp is increasing

      you could also notice more vegetation in agricultural zones that were once deserts such as California valleys, but much of that actually emits more carbon than it absorbs due to the use of fertilizers and pesticides.

    • You can find it as hard to believe as you want, Mr. Reynolds, but those are the actual measurements.

      A large portion of the carbon in the atmosphere is absorbed by ocean plant life – algae and plankton. Those are experiencing problems due to ocean temperature increases, pollution, and changes in ocean salinity. Their loss is not offset by some of the land-based gains we may have had. You also have the problem of more and more forestland cut down to create farmland, which does not absorb as much carbon.
