The Research in Astronomy and Astrophysics Journal released a study that attributes changes in the Earth’s average global temperature “to natural cycles, chiefly
long-term changes in the energy emitted by the Sun,” not “human-caused emissions.”
Twenty-three solar physicists from 14 nations authored the peer-reviewed study and concluded that some scientists were “premature” in linking climate change and greenhouse gas emissions, specifically carbon dioxide, the Epoch Times reported.
The study challenges the UN Intergovernmental Panel on Climate Change’s recent “unequivocal” conclusion that man’s carbon dioxide emissions cause climate change.
The scientists studied 16 solar output datasets, including the UN IPCC’s own datasets, and found that two different methodologies led to far different results.
The IPCC’s scientists, on the one hand, assumed that “available temperature records are unaffected by the urban heat island problem, and so all stations are used, whether urban or rural.”
The UN’s researchers further assumed “zero contribution from natural factors to the long-term warming.”
The 23 independent scientists, on the other hand, used only rural temperature records and data from NASA’s ACRIM sun-monitoring satellites.
The study’s lead author, Ronan Connolly, a scientist at the Center for Environmental Research and Earth Sciences, said the IPCC has perverted the scientific process for political gain.
“The IPCC is mandated to find a consensus on the causes of climate change. I understand the political usefulness of having a consensus view in that it makes things easier for politicians,” he said.
“However, science doesn’t work by consensus,” he added. “In fact, science thrives best when scientists are allowed to disagree with each other and to investigate the various reasons for disagreement.”
Connolly said he allowed scientists on the project to present “different scientific opinions on many of the issues discussed,” rather than encouraging them to reach a consensus.
“I fear that by effectively only considering the datasets and studies that support their chosen narrative, the IPCC have seriously hampered scientific progress into genuinely understanding the causes of recent and future climate change,” he said. “I am particularly disturbed by their inability to satisfactorily explain the rural temperature trends.”
