“Periodicities of solar activity and the surface temperature variation of the Earth and their correlations”

The co-corresponding authors are Dr. Zhao Xinhua and Dr. Feng Xueshang from State key laboratory of space weather, CSSAR/NSSC,
Chinese Academy of Sciences. It adopts the wavelet analysis technique and cross correlation method to investigate the periodicities of solar
activity and the Earth’s temperature as well as their correlations during the past centuries.

Global warming is one of the hottest and most debatable issues at present. The Intergovernmental Panel on Climate Change (IPCC) claimed
that the release of the anthropogenic greenhouse gases contributed to 90% or even higher of the observed increase in the global average
temperature in the past 50 years. However, the debate on the causes of the global warming never stops. Research shows that the current
warming does not exceed the natural fluctuations of climate. The climate models of IPCC seem to underestimate the impact of natural factors
on the climate change, while overstate that of human activities. Solar activity is an important ingredient of natural driving forces of climate.
Therefore, it is valuable to investigate the influence of solar variability on the Earth’s climate change on long time scales.

This innovative study combines the measured data with those reconstructed to disclose the periodicities of solar activity during centuries and
their correlations with the Earth’s temperature. The obtained results demonstrate that solar activity and the Earth’s temperature have significant
resonance cycles, and the Earth’s temperature has periodic variations similar to those of solar activity (Figure 1).

This study also implies that the “modern maximum” of solar activity agrees well with the recent global warming of the Earth. A significant
correlation between them can be found.

As pointed out by a peer reviewer, “this work provides a possible explanation for the global warming”.

Well when the last time co2 exceeded current levels, they did not have our current population, nor were they trying to feed the current population numbers. However one of the major problems today is the way our land use has divided up the land, so the migration of plants and animals has been greatly reduced, therefore they cannot escape the changing environment. Also it is the speed it is happening and creatures do not have time to adjust or establish new viable colonies.

We know this. The correlation has been extremely good. But the magnitude of incoming solar radiation changes completely fails to match the magnitude of global warming.
