The National Oceanic and Atmospheric Administration (NOAA) released a statement today that carbon dioxide levels have reached a new global level of 400 parts per million for March, even though global temperatures have not risen for nearly 19 years. This means that for March 2015, carbon dioxide levels across the globe remained at 400 ppm* for the entire 31-day period with no increase in global mean temperatures as measured by RSS satellites.
NOAA began tracking its own carbon dioxide (CO2) levels in May 1974 concomitantly with the Scripps Institution of Oceanography. The first measurement of atmospheric CO2 levels was started by C. David Keeling of the Scripps Institution of Oceanography in 1958 on Mauna Loa, Hawaii. Prior to that, NOAA has relied on ice core samples and sediment for earlier reconstructions of atmospheric CO2 levels. The International Energy Agency, however, reported on March 13 that global emissions from the burning of fossil fuels stalled in 2014, never rising above 2013 levels.
According to NOAA, the March CO2 levels were recorded from 40 different sites in both hemispheres, with some of them being situated on cargo ship decks, remote islands, and other locations not close to areas that emit large amounts of CO2. The global average is then computed based on the samples sent in from these various locations to NOAA’s Earth System Research Laboratory in Boulder, Colo.
Now that the global warming “hiatus” has expanded to a new record length of 18 years and five months, the RSS satellite temperature record shows a sub-zero trend. But if El Niño conditions occur this year, this may interrupt the warming pause, though the discrepancy between prediction and observation continues to widen. According to Christopher Monckton, who has studied the climate extensively, “the divergence between the models’ predictions in 1990 (Fig. 2) and 2005 (Fig. 3), on the one hand, and the observed out-turn, on the other, also continues to widen.”
“Not only does the RSS satellite dataset show no global warming from December 1996 to April 2015, which is more than half of the entire satellite record,” Monckton writes, “But the warming trend since 1900 is roughly 0.8°C per century, well within natural variability.” NOAA also expects that the higher CO2 levels will remain that way through May, but drop to lower levels as plants in the Northern Hemisphere begin to bloom, utilizing the CO2 for photosynthesis in the spring and summer.
According to some climate scientists, an increase in carbon dioxide levels as seen in the 20th and 21st century should cause a subsequent increase in global temperatures. Even the IPCC’s prediction of 4.8°C warming by 2100 is “over four times the observed real-world warming trend when humans began influencing the climate in 1950.” Even the oceans, according to the 3600+ ARGO bathythermograph buoys, are warming at a rate “equivalent to just 0.02°C per decade, or 0.23°C per century, well within the normal rate of warming,” according to Monckton.
He also notes that, “If the ‘deep heat’ explanation for the hiatus in global warming were correct (and it is merely one among dozens that have been offered), then the complex models have failed to account for it correctly: otherwise, the growing discrepancy between the predicted and observed atmospheric warming rates would not have become as significant as it has.”
In a nutshell, what we’re observing and what is being predicted simply aren’t aligning (Fig. 4). Though CO2 is attributed as a potent greenhouse gas that will be lingering around for hundreds of years, the inescapable truth is that the man-made global warming theory simply fails at every observable test.
*ppm (parts per million): You can find 400 carbon dioxide molecules per one million parts of dry air. By volume, “dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide (.04% in March 2015), and small amounts of other gases.”
