Of the warming trends in Poland and greater Europe, “only about 4–5% are explained by an increase in CO2 concentration.”  –  Marsz et al., 2022 

Internal changes to the thermal structure of the ocean transmit decadal-scale changes in the atmospheric circulation and consequent surface air temperature via its modulating impact on the variation in the amount and intensity of solar radiation (sunshine duration, or SD) reaching the Earth’s surface.

This is not only observed for Poland and/or Europe as detailed in a new study, but the causal structuring of cloud cover changes driving the variations in solar radiation reaching the surface and modulating climate can be applied throughout the globe ( Wang et al., 2002, Wielicki et al., 2002, Loeb et al., 2021, Herman et al., 2013, Poprovsky, 2019, Dübal and Vahrenholt, 2021, Swift, 2018, Stephens et al., 2022).

Therefore, “the main cause of the change in the state of the climate may be the action of the internal variability of the ocean–atmosphere system” (Marsz et al., 2022).
