Here is a possible ionizing radiation connection.

The most precise correlation of changes in the Earth's temperature 
are associated with solar activity, especially sun spot frequency and 
cycle period changes on a year to year basis. The radiant energy 
emitted by the Sun on a year to year basis does not change appreciably.

One theory relates to the intense flux of high energy cosmic protons 
continuously hitting the outer atmosphere. The high energy ionization 
process and the accompanying ionization showers in the atmosphere 
lead to the formation of condensation nuclei and small droplets that 
create a diffuse cloud in the atmosphere that reflects radiant energy 
from the sun out into space acting as a heat shield. The Earth's 
albedo is increased. This natural process tends to cool the Earth.

However, in years when there is considerable sunspot activity and 
associated electromagnetic storms emanating from the Sun, the proton 
flux is disturbed in a way that causes a reduction in the production 
of condensation nuclei in the atmosphere. Consequently, more of the 
Sun's radiant energy is absorbed by the Earth with associated warming.

This phenomenon has been seen to be rather precisely effective in the 
past. From about 1900 to 1940 Sunspot cycles became increasingly 
closer to together and the Earth's temperature rose. Atmospheric 
carbon dioxide emissions also rose. Then from about 1940 to 1980 
Sunspot cycles became increasingly further apart and the Earths 
temperature markedly dropped. There were articles written predicting 
the advent of a new ice age! During that period carbon dioxide 
emissions continued to rise as the Earth cooled!

Then from about 1980 to about 2000 the sunspot activity picked up 
again and the Earth warmed. I believe that the current global warming 
craze was conceived following that period.

Since 2000 the solar sunspot activity has dropped again and the Earth 
has been cooling.

Over these periods there is no meaningful relationship between carbon 
dioxide emissions and global warming. After all, the concentration of 
carbon dioxide in the atmosphere is puny compared to the main 
greenhouse gas which is water vapor.

So ionizing radiation may explain temporal changes in the Earth's temperature.
