That crap from Junk Science, just is that...

The moves in CO2 concentrations illustrated in your neato trends are over millions of years and one cannot compare the prehistorical moves the recent moves during our short industrialized history. The data is iffy and doesn't illustrate anything. However, the recent moves in CO2 concentration are ALARMING.

Note that the elevated CO2 concentrations during the Paleozoic Era were partly responsible for melting of the polar ice caps in that time and mass extinctions. Junk Science in it's junk manner fails to mention that.

Climate scientists have weighed in, with a solid concensus (as solid as one can get), that GW is REAL and MAN MADE. All western governments acknowledge it. No amount of RWE spinning will change it as FACT.

CO2-Forced Climate and Vegetation Instability During Late Paleozoic Deglaciation

The late Paleozoic deglaciation is the vegetated Earth's only recorded icehouse-to-greenhouse transition, yet the climate dynamics remain enigmatic. By using the stable isotopic compositions of soil-formed minerals, fossil-plant matter, and shallow-water brachiopods, we estimated atmospheric partial pressure of carbon dioxide (pCO2) and tropical marine surface temperatures during this climate transition. Comparison to southern Gondwanan glacial records documents covariance between inferred shifts in pCO2, temperature, and ice volume consistent with greenhouse gas forcing of climate. Major restructuring of paleotropical flora in western Euramerica occurred in step with climate and pCO2 shifts, illustrating the biotic impact associated with past CO2-forced turnover to a permanent ice-free world.

You didn't answer my question directly although I think I know the answer....
