A CONVENIENT EXCUSE: more proof that the conclusion that man-made CO2 causes global warming is wrong


"SCIENCE" IS A LEADING SCIENTIFIC JOURNAL. TWO PAPERS FROM IT DISPROVE THE PC ASSERTION THAT MAN-MADE CO2 CAUSES GLOBAL WARMING. FIRST LOOK AT THIS:



Fig. 4. A composite CO2 record over six and a half ice age cycles, back to 650,000 years B.P. The record results from the combination of CO2 data from three Antarctic ice cores: Dome C (black), 0 to 22 kyr B.P. (9, 11) and 390 to 650 kyr B.P. [this work including data from 31 depth intervals over termination V of (1)]; Vostok (blue), 0 to 420 kyr B.P. (5, 7), and Taylor Dome (light green), 20 to 62 yr B.P. (8). Black line indicates {delta}D from Dome C, 0 to 400 kyr B.P. (1) and 400 to 650 kyr B.P. (18). Blue line indicates {delta}D from Vostok, 0 to 420 kyr B.P. (7).

The CO2 record from the EPICA Dome C ice core reveals that atmospheric CO2 variations during glacial-interglacial cycles had a notably different character before and after 430 kyr B.P. Before MIS 11, the amplitude of temperature was lower, and the duration of the warm phases has been much longer since then. In spite of these differences, the significant covariation of {delta}D and CO2 is valid in both periods. Before MIS 11, CO2 concentrations did not exceed 260 ppmv. This is substantially lower than the maxima of the last four glacial cycles. The lags of CO2 with respect to the Antarctic temperature over glacial terminations V to VII are 800, 1600, and 2800 years, respectively, which are consistent with earlier observations during the last four glacial cycles.

AND THEN LOOK AT THIS:
Ice Core Records of Atmospheric CO2 Around the Last Three Glacial Terminations

Hubertus Fischer, Martin Wahlen, Jesse Smith, Derek Mastroianni, Bruce Deck

Air trapped in bubbles in polar ice cores constitutes an archive for the reconstruction of the global carbon cycle and the relation between greenhouse gases and climate in the past. High-resolution records from Antarctic ice cores show that carbon dioxide concentrations increased by 80 to 100 parts per million by volume 600 ± 400 years after the warming of the last three deglaciations. Despite strongly decreasing temperatures, high carbon dioxide concentrations can be sustained for thousands of years during glaciations; the size of this phase lag is probably connected to the duration of the preceding warm period, which controls the change in land ice coverage and the buildup of the terrestrial biosphere. [Umph addd.]
These two data series and their analysis show that the ice core record for the last 650,000 years actually proves that increases in atmospheric CO2 does not cause global warming, but that it is a lagging indicator.

I assert that the Left has made CO2 the bogeyman in an effort to attack three of the Left's long-time "foes": free market capitalism, industrialization and consumerism. Their remedy for "global warming caused by man-made greenhouse gases" is higher taxes, more regulation and less consumption - THREE THINGS THEY HAVE LONG ADVOCATED.

NOW THAT'S CONVENIENT!
