Further Analysis of Data from Berkeley Earth Clearly Indicate that Climate Change During the Period 1860 to 2020 is Driven by the Sun

From [HERE] In a recent analysis of global temperature data from Berkeley Earth (1), I found that the main factor driving the temperature increase from 1860 to 2020 is the earth's orientation to the sun. Despite criticism from those who believe in anthropogenic climate change, accusing me of being sponsored by the oil industry and lacking “climate science” qualifications, I responded politely. I also made a mental note that industry sponsorship could supplement my pension. Critics did not engage with the data or provide a compelling argument. I questioned what qualifications are needed to conduct basic data analysis in Excel. A more relevant question is why this type of analysis hasn't been published already. Critics argued that Milankovitch cycles operate on longer timescales and cannot explain current climate change. While true, the specific timing within the solar cycles could be crucial, and the existence of unidentified shorter cycles is possible. I also overlooked the 11-year solar cycles that influence short-term changes in the sun's activity. If these cycles influence climate change, they could help identify a solar signal within temperature records.

Further reading revealed that there is strong evidence that the 11-year solar cycles do impact our climate (2). To maximise the ability to detect this solar signal in temperature data, we require a climate change-sensitive region, high-resolution monthly data, a specific time of year, and a relevant cycle period that aligns with the phase. Previous analysis showed that the northern hemisphere warms faster than southern latitudes, with winter having a more significant impact than summer. For example, the warming rate in January in Greenland from 1860 to 2020 is 6.5 times greater than in July. On this basis I conducted a specific analysis on the January temperature anomaly record in Greenland to identify any potential solar signature. [MORE]
