A paper published in Geophysical Research Letters finds no statistically significant increase inÂ the airborne proportion of anthropogenicÂ carbon dioxide over the past 150 years. Being that climate scientists like those from the Climactic Research Unit at Hadley and alarmist members of the UNâ€™s Intergovernmental Panel on Climate Change (IPCC) claims that increased CO2 is to blame for warming patterns over the past several decades and that the warming Â will soon accelerate out of control, due to an inability of the ecosystem toÂ cope with increased CO2 emissions, this research poses a problem. How can carbon dioxide be causing warming if the level of CO2 in the atmosphere has not actually been on the rise?
We know that mankind does produce and emit a relatively small (compared to naturally occurring CO2) amount of CO2 and industrialization has increased our overall CO2 emissions, but now it seems that it hasnâ€™t mattered. The earthâ€™s natural mechanisms have effectively dealt with the increase. Vegetation, like forests and ocean algae, of course thrive on CO2 and convert it into Oxygen.
A December 31st article in Science Daily noted, â€œMost of the carbon dioxide emitted by human activity does not remain in the atmosphere, but is instead absorbed by the oceans and terrestrial ecosystems.â€
Despite the new evidence that CO2 cannot have been responsible for the recent reported warming (that ended around 1999), the warmists are undeterred. The article goes on to say, â€œHowever, some studies have suggested that the ability of oceans and plants to absorb carbon dioxide recently may have begun to decline and that the airborne fraction of anthropogenic carbon dioxide emissions is therefore beginning to increase.
â€œMany climate models also assume that the airborne fraction will increase. Because understanding of the airborne fraction of carbon dioxide is important for predicting future climate change, it is essential to have accurate knowledge of whether that fraction is changing or will change as emissions increase.â€
So, the new line may well be: Even though it hasnâ€™t happened at all yet, future increases in atmospheric carbon dioxide will cause global warming, because weâ€™re on the verge of maxing out the earthâ€™s ability to absorb CO2.
It seems the climate models may now rely on predicting a heretofore unobserved increase in anthropogenic carbon dioxide in the atmosphere in order to predict future CO2-driven global warming, even though (despite earlier claims) neither has actually been observed.
Every claim of the warmists has been disproven. Not a single catastrophic prediction has come to pass. They insist the science is settled and the debate is over but science is based on observation and duplicable results. Observation shows no CO2-induced warming and the CRUâ€™s climate models havenâ€™t produced one accurate result, let a lone a duplicate. The warmists it seems, will unabashedly stretch to any length to try to maintain their dreams of carbon-based economic control, but the thing about stretching something is that it also grows thin.
