The sun and not human emissions of carbon dioxide (CO2) may be the main cause of warmer temperatures in recent decades, according to a new study with findings that sharply contradict the conclusions of the United Nations (UN) Intergovernmental Panel on Climate Change (IPCC).
The peer-reviewed paper, produced by a team of almost two dozen scientists from around the world, concluded that previous studies did not adequately consider the role of solar energy in explaining increased temperatures.
The new study was released just as the UN released its sixth “Assessment Report,” known as AR6, that once again argued in favor of the view that man-kind’s emissions of CO2 were to blame for global warming. The report said human responsibility was “unequivocal.”
But the new study casts serious doubt on the hypothesis.
Calling the blaming of CO2 by the IPCC “premature,” the climate scientists and solar physicists argued in the new paper that the UN IPCC’s conclusions blaming human emissions were based on “narrow and incomplete data about the Sun’s total irradiance.”
Indeed, the global climate body appears to display deliberate and systemic bias in what views, studies, and data are included in its influential reports, multiple authors told The Epoch Times in a series of phone and video interviews.
“Depending on which published data and studies you use, you can show that all of the warming is caused by the sun, but the IPCC uses a different data set to come up with the opposite conclusion,” lead study author Ronan Connolly, Ph.D. told The Epoch Times in a video interview.
“In their insistence on forcing a so-called scientific consensus, the IPCC seems to have decided to consider only those data sets and studies that support their chosen narrative,” he added.
The implications, from a policy perspective, are enormous, especially in this field where trillions of dollars are at stake and a dramatic re-organization of the global economy is being proposed.
Paper Examines Sun Vs. CO2
Using publicly available data sets from the U.S. government and other sources, it is easy to explain all of the warming observed in recent decades using nothing but changes in solar energy arriving on Earth, according to the new paper.
Indeed, while it agrees that using the data sets chosen by the UN would imply humans are largely to blame, the study includes multiples graphs showing that simply choosing different data sets not used by the UN upends the IPCC’s conclusion.
If confirmed, the study, published in the international scientific journal Research in Astronomy and Astrophysics (RAA) by experts from over a dozen countries, would represent a devastating blow to the UN IPCC and its conclusion that man’s emissions of CO2 are the sole or even primary driver of warming.
While the paper calls for further research to resolve differences between conflicting data sets and studies, the authors show conclusively that, depending on the data sets being used, it is entirely possible that most or even all of the warming has nothing to do with man.
Using 16 different estimates on the amount of solar energy, dubbed “Total Solar Irradiance,” the review compares that data with over 25 estimates of temperatures in the Northern hemisphere stretching back to the 1800s.
When solar data from NASA’s “ACRIM” sun-monitoring satellites are compared to reliable temperature data, for example, virtually all of the warming would be explained by the sun, with almost no role at all for human emissions.
And yet, for reasons that the study authors say are murky at best, the UN chooses to ignore the NASA ACRIM data and other data sets in favour of those that support the hypothesis of human responsibility for climate change.
The UN IPCC reports, including the recently released 6th Assessment Report, have consistently blamed human activities such as the emission of so-called “greenhouse gases” for the observed changes. Many studies in the scientific literature have agreed with the UN IPCC position.
However, the new study, titled “How much has the Sun influenced Northern Hemisphere temperature trends? An ongoing debate,” cites dozens of other studies that have pointed to the sun—not human activity—as the primary driver of climate changes.
According to the study authors, these dissenting scientific views have been deliberately suppressed by the IPCC and have not been reflected in the UN IPCC reports, for reasons that have not been adequately explained.

It has long been evident that to understand recent warming, you first have to understand what plunged the Earth into the Little Ice Age, the coldest period since the Ice Age. This latest paper addresses this question in a way that the AGW theory does not.
