The National Oceanic and Atmospheric Administration (NOAA) released a statement todaythat 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.







I think that Fred puts me into this detestful category of deniers and the issue is again that (in)famous “back radiation” or Downwelling Longwave Radiation DLR. Fred writes:
