Hundreds of publications show how climate in many regions around the world varies in sync with solar activity. More evidence is provided by Japanese climate scientist Kyoji Kimoto.
Climate Change Governed By The Sun

I’ve compiled a list of six examples how the sun impacts climate across the globe.
1. Climate periods based on a double Hale (44-45 years) cycle of solar activity.
In 1977 Australian geologist Rhodes W. Fairbridge found a 45-year periodicity of beach ridge located at the Hudson Bay. It has been formed with storms in Hudson Bay caused by a wavier jet stream.
I have found a 44-year periodicity of heavy snowfall in Japan caused by the wavier jet stream as follows. The time series coincide quite well with that of Fairbridge (1977).
1833 Tempo famine, Dalton minimum (1795-1830)
1877 Seinan war (44 years later)
1918 Rice riot, Gleissberg minimum (1898-1923) (41 years later)
1963 38 heavy snowfall (45 years later)
2006 Heisei 18 year heavy snowfall, Gleissberg or Dalton minimum (43 years)
The climate history of 20th century can be divided with the following 5 periods based on the double Hale cycle above using aa-index of geomagnetism associated with solar activity. The Pacific Climate Shift occurred at 1977 with solar activity increase & a positive PDO index.
1900-1918: Little Ice Age (LIA)
1919-1962: 1st Modern Warm Period (1st MWP)
1963-1976: Temporal Cold Period (TCP, New Ice Age Coming, see below)
1977-2005: 2nd Modern Warm Period (2nd MWP)
2006 – present: New Cold Period (NCP)

2. Hachijo-jima temperature time series
Hachijo-jima is a volcanic Japanese island some 287 kilometers south of Tokyo, where 7,522 people live on its 63 km2 of area.
The following time series shows how the temperature at Hachijo-jima generally has varied in line with the climate periods based on solar activity above.

3. Arctic sea ice extent
Connolly et al. (2017) showed the variation of Arctic sea ice extent due to solar activity change in line with the climate periods above.

Fig. 5 below is a chart from the NOAA that shows Arctic sea ice loss from the maximum at 1979 above:

The sea ice loss rate has decreased since 2006 with the beginning of NCP above.
Warm sea water penetrated into the Arctic sea after the big El Nino at 1998, accelerating the sea ice loss. Moreover, low solar activity since 2006 has caused a wavier jet stream and frequent Arctic heat wave with abrupt sea ice loss, as discussed in Section 5.
4. Hurricane strength
In the following table, the third strongest hurricane Labor Day hit in 1935. Hurricane Katrina, Sandy, Irma and Harvey show much higher central pressure. Alarmists and media erroneously loudly claimed that they were caused by the anthropogenic global warming (AGW). Interestingly all five of the strongest hurricanes hit in 1st MWP or 2nd MWP. (WMP 1= 1919-1962; TCP = 1963-1976; MWP 2 = 1977-2005; NCP = 2006 – present)

5. Wavier jet stream due to decreased solar activity
Low solar activity since 2006 has caused wavier jet stream as shown below. It causes extreme weather (ExWe) such as heat waves, flooding and heavy snowfall.

The following table shows the extreme weather seen since 2006:

6. Climate history of the Earth
Based on bore-hole studies of the Greenland ice sheet, Dahl-Jensen et al (1998) showed the following temperature data compared with the present time.
Medieval Warm Period: +1°K,
Little Ice Age: -1°K,
Warm period 1930s: +0.5°K
The following data will support Dahl-Jensen’s finding of a warm period in the 1930s:

A NASA study finds that 1934 had the worst drought of the last thousand years.
Lamb’s graph (IPCC 1990) showed climate change is governed by solar activity with MWP & LIA. In contrast, Mann’s graph (IPCC 2001) erased MWP & LIA to emphasize the dubious IPCC AGW and is based on fudged model studies and mathematical errors.

And the temperature history of China:

In summary, Climate variability is largely tied to solar activity, and trace gas CO2 has little to do with it.
