If his hypothesis had a comparably straightforward account showing an excellent correlation
between some global temperature dataset and another observable (his alternative to CO2 as the control knob) it would be a good contender, but so far Miskolczi has been unable to bring any clarity to his hypothesis.
This has since been done, and the conclusions are surprising: «We find insufficient evidence to claim a statistical relationship
between global temperature increase and normalized catastrophe losses,» read the report published in the compendium «Climate Extremes and Society.»
Individual model parameterizations were constrained by paleontological data, and the overall modeled relationship
between global temperature and sea level matched well against records from four previous warm periods: preindustrial, the last interglacial, marine isotope stage 11, and the mid-Pliocene.
Then in 2014, research in the journal Climate Risk Management using rigorous statistical techniques revealed an objective link
between global temperature increases and human activity, with a probability exceeding 99.999 percent.
However, a search for some reconsiliation
between the global temperature record and possible BNO (R) forcings by altering its strength and / or timing (be it in the form of square wave or sine wave or any other wave) may show nothing other than the existence of many competing and controversial alternatives.
We find good correspondence
between global temperature and solar induced temperature curves during the pre-industrial period.
My attention was drawn in August to a draft version of a paper by Phil Klotzbach and colleagues that discussed the differences
between global temperature products.
There is nothing there beyond the regular short - term variability primarily due to ENSO, and of course we should smooth enough to get rid of this short - term variability when testing for the kind of long - term linkage
between global temperature and sea level that we expect.
It requires quite some skill to produce a misleading graph like Watts» global climate widget, which hides the actual connections
between global temperature, CO2 and the sunspot cycle.
The link
between global temperature and rate of sea level change provides a brilliant opportunity for cross-validation of these two parameters over the last several millenia (one might add - in the relationship between atmospheric [CO2] and Earth temperature in the period before any significant human impact on [CO2]-RRB-.
Researchers have discovered a strong historical link
between global temperature increases and increases in volcanic activity.
Berntsen at al used statistics to investigate the relationship
between global temperatures and changes in radiative forcing.
The fossil record has repeatedly shown that there is absolutely NO relationship
between global temperatures and atmospheric CO2 concentrations.
We have also seen over the past 20 years that the IPCC has directed much of its resources, publications, and findings to establish a link
between global temperatures and man - made CO2, attempting to portray it as the culprit in global climate change.Stated more clearly (the UN and its agencies are rarely «clear» on anything), the IPCC statement above contains huge and unproven assumptions.
Data received by the WMO show no statistically significant difference
between global temperatures in 2010, 2005 and 1998.
The difference
