Cult of Climastrology members think the primary, heck, in some cases, the only, driver of climate. At lest during the current warm period. Reality and science say different. This comes via NoTricksZone
The sun drives the climate: Proof of the 90 and 200-year cycles in the earth’s climate history
By Dr. Sebastian Lüning and Prof. Fritz Vahrenholt
(Translated/edited by P Gosselin)Solar activity fluctuates very much in cycles, among them the Gleissberg Cycle over 90 years, plus or minus 30 years. In March 2015 a study by Orgutsov et al. appeared in the journal Advances in Space Research which discovered the solar Gleissberg Cycle during the growth period of the northern hemisphere over the past 450 years. The authors suspected a solar impact on temperatures on plant growth. The abstract:
Evidence for the Gleissberg solar cycle at the high-latitudes of the Northern Hemisphere
Time evolution of growing season temperatures in the Northern Hemisphere was analyzed using both wavelet and Fourier approaches. A century-scale (60–140 year) cyclicity was found in the summer temperature reconstruction from the Taymir peninsula (∼72° N, ∼105° E) and other high-latitude (60–70° N) regions during the time interval AD 1576–1970. This periodicity is significant and consists of two oscillation modes, 60–70 year and 120–140 year variations. In the summer temperatures from the Yamal peninsula (∼70° N, ∼67° E) only a shorter-term (60–70 year) variation is present. A comparison of the secular variation in the Northern Hemisphere temperature proxies with the corresponding variations in sunspot numbers and the fluxes of cosmogenic 10Be in Greenland ice shows that a probable cause of this variability is the modulation of temperature by the century-scale solar cycle of Gleissberg. This is consistent with the results obtained previously for Northern Fennoscandia (67°–70° N, 19°–33° E). Thus, evidence for a connection between century-long variations in solar activity and climate was obtained for the entire boreal zone of the Northern Hemisphere.â€A year earlier Ogurtsov and a Finnish colleague had already published another paper on the Gleissberg cycles in the Journal of Atmospheric and Solar-Terrestrial Physics. Back then they reported a solar Gleissberg Cycle in the nitrate concentrations in polar ice cores:
Head on over and read the rest.
We also know that the 11 year solar cycle has an undeniable impact on climate. And there are 23 major papers this year alone on the complex topic of the sun and climate.
Warmists are more than willing to admit that the Sun was one of the major drivers of climate, along with other natural processes, in past warm and cool periods. But, now, they will barely admit that the sun and other natural drivers have any effect. It couldn’t possibly be because they have a political agenda, could it?
