IPCC's Gold-Standard HadCRUT Confirms: CO2's Impact On Global Temps Statistically
Immaterial & Insignificant
The extreme anti-CO2 jihadists, and the green-fundamentalists at the UN's IPCC, claim
that modern warming has been historically unusual, unique and statistically "significant"
due to human CO2 emissions - yet, when the UK's HadCRUT4 global temperature dataset
is examined, it is readily apparent that modern temperature change is primarily a
repeat of the past natural climate patterns
Global warming modern 60 year vs previous 60 years Hadcrut co2Recently, the UK's
MetOffice was forced to admit to Parliament that global warming since the 1850's
has not been statistically significant - read here, here and here.
In essence, for the recent modern warming to be statistically significant, then there
should be no earlier periods exhibiting a similar warming trend and monthly variation
that occurred when CO2 levels were low.
So, exactly how hard was it to find an earlier warming period that took place under
a low atmospheric CO2 regime that had similar traits? Hmmm.....not so hard, as it
Despite the previous statistical gyrations the MetOffice utilized to convince both
lawmakers and the public that human CO2 emissions caused modern global warming to
be "statistically" unique, in fact, upon analysis, the recent modern warming is typical
of past natural climate variation.
Without conducting the type of statistical analysis that forced the MetOffice admission
of being wrong (you can read about at those above article links), one can easily
recognize earlier periods exhibiting similarity. The adjacent chart depicts such
a similar period.
As can be discerned visually from the chart, the modern warming over the last 60
years (green data plots) ending April 2013 has obvious similarities to the 60-year
climate period ending November 1949 (blue data plots). These two 720-month periods
look very similar with the exception of atmospheric CO2 growth.
