“To what extent are temperature levels changing due to greenhouse gas emissions?” may prove to be the most important scientific paper in the last 10 years.
Statistics Norway just published a bomb-shell of a paper that offers a real analysis of global temperatures. The English translation of the paper is available HERE, and is well worth looking at for anyone interested in the facts behind global temperature trends.
Climate Discussion Nexus offers an introduction to why this paper is so important:
Well, this is awkward. Statistics Norway, aka Statistisk sentralbyrå or “the national statistical institute of Norway and the main producer of official statistics”, has just published a paper “To what extent are temperature levels changing due to greenhouse gas emissions?”
The awkward part isn’t trying to grasp the subtleties of Norwegian since it’s also available in English. It’s that the Abstract bluntly declares that “standard climate models are rejected by time series data on global temperatures” while the conclusions state “the results imply that the effect of man-made CO2 emissions does not appear to be sufficiently strong to cause systematic changes in the pattern of the temperature fluctuations.”
But the really awkward part is that a paper from a government agency dares to address openly so many questions the alarmist establishment has spent decades declaring taboo, from the historical record on climate to the existence of massive uncertainty among scientists on it.
What the Norwegians did was conduct statistical analyses of observed and reconstructed temperature series and test whether the recent fluctuation in temperatures differs systematically from previous temperature cycles potentially due to the emission of greenhouse gases. For example, the researchers gathered all the data from various sources, including those related to the four previous glacial and inter-glacial periods, and did a statistical analysis to see how more recent Global Climate Models (GCMs) compare.
In the global climate models (GCMs) most of the warming that has taken place since 1950 is attributed to human activity. Historically, however, there have been large climatic variations. Temperature reconstructions indicate that there is a ‘warming’ trend that seems to have been going on for as long as approximately 400 years. Prior to the last 250 years or so, such a trend could only be due to natural causes.
The length of the observed time series is consequently of crucial importance for analyzing empirically the pattern of temperature fluctuations and to have any hope of distinguishing natural variations in temperatures from man-made ones. Fortunately, many observed temperature series are significantly longer than 100 years and in addition, as mentioned above, there are reconstructed temperature series that are much longer.
I was recently discussing the fact that Earth is warming from its last glaciation period. The Norwegian statisticians’ comprehensive temperature review takes the long view into account by looking at the last 420,000 years.
The statisticians take all the data, show their calculations, offer their explanations, and come to the following conclusion:
In this paper we have reviewed data on climate and temperatures in the past and ascertained that there have been large (non-stationary) temperature fluctuations resulting from natural causes.
Subsequently, we have summarized recent work on statistical analyses on the ability of the GCMs to track historical temperature data. These studies have demonstrated that the time series of the difference between the global temperature and the corresponding hindcast from the GCMs is non-stationary. Thus, these studies raise serious doubts about whether the GCMs are able to distinguish natural variations in temperatures from variations caused by man-made emissions of CO2.
…[T]he results imply that the effect of man-made CO2 emissions does not appear to be sufficiently strong to cause systematic changes in the pattern of the temperature fluctuations. In other words, our analysis indicates that with the current level of knowledge, it seems impossible to determine how much of the temperature increase is due to emissions of CO2.
I get to place another item in the “Leslie Was Right” files.
… Norwegian brains decided to double-check the work of the climate crowd, only to discover a massive fraud. The overly simplistic “greenhouse effect” account of rising CO2 levels correlating perfectly with rising global temperatures fell apart upon further examination.
…[W]e skeptics have been right all along.
Why are Norway statisticians bravely publishing this treatise destroying climate cult theology? Perhaps because their leaders now recognize that a civilized life is contingent upon having highly efficient energy sources… such as fossil fuels and nuclear power.
It’s also important for their nation’s security.
The Norwegian government is calling on energy giants to ramp up oil and gas exploration projects in remote regions like the Arctic Barents Sea, defying a sense of palpable frustration among climate campaigners as the Nordic country seeks to shore up its position as Europe’s largest gas supplier.
The rethink in strategy comes as Norway strives to keep up with growing demand for its energy exports in the wake of Russia’s full-scale invasion of Ukraine.
Norway last year overtook Russia as Europe’s biggest natural gas supplier and says it is now seeking to maintain Europe’s energy security by exploring the Barents Sea for further resources.
