Baltic Sea surface temperatures may have reached 24°C 7,200 years ago compared to the current 12.7°C.
A new study (Weiss et al., 2022) indicates Baltic Sea regional surface temperatures ranged between 21-24°C from ~5.7 to 7.7 ka (thousand years ago). This period is referred to as the Baltic’s Holocene Thermal Maximum.
Temperatures dipped to 17.2°C at 1.373 ka. (The time span ranging from 0.0 ka to 3 ka is referred to in the study as the Modern Baltic, or M.B.)
The current (0.0 ka) surface temperature for the Baltic S is 12.7°C. This temperature is more than 11°C colder than the Baltic’s temperatures at 7.2 ka.

In its most recent video, German site Die kalte Sonne here looks at a paper on CO2 climate forcing by Stefani 2021: Solar and Anthropogenic Influences on Climate: Regression Analysis and Tentative Predictions. The results point to only a moderately warming planet up to the year 2150.
To hype up climate warming alarm, IPCC scientists like to exaggerate CO2’s power to trap heat and warm up the atmosphere. But with every assessment report that the IPCC issues, the estimated value by which CO2 warms the planet steadily gets reduced as the observed warming keeps lagging behind what earlier models predicted.
In his paper, Frank Stefani and his team at the Helmholtz Center, Institute of Fluid Dynamics in Dresden, Germany looked at the impacts by CO2 and solar activity.
On average 1.1°C warming
Using double regression, the scientists evaluated linear combinations of the logarithm of the carbon dioxide concentration and the geomagnetic aa index as a proxy for solar activity. They reproduced the sea surface temperature (HadSST) since the middle of the 19th and ended up with a a climate sensitivity (of TCR type) in the range of 0.6 K until 1.6 K per doubling of CO2. The midpoint of this range is 1.1°C, a value many critical climate scientists have already estimated earlier, and thus far below the IPCC scary estimates.
The paper’s abstract elaborates further:

The devastating Russian invasion of Ukraine has captured global attention. While the world’s focus is rightly on the human toll and suffering, the crisis has highlighted the need to end reliance on Russian oil and gas. [bold, links added]
To achieve that ambition, we must be pragmatic and invest in sensible alternatives, not engage in wishful thinking about renewable energy.
Every single day, the world spends more than a billion dollarson fossil fuels from Russia, according to Bloomberg reporting.
As Ukrainian Foreign Affairs Minister Dmytro Kuleba tweeted, that money is now paying for the “murder of Ukrainian men, women, and children.” We must end this reliance.
However, this has proved to be easier said than done: Over dozens of years, the world has exchanged trillions of dollars for fossil fuels from the Soviet Union and now from Russia. Our continued use of Kremlin-backed oil and gas reveals two inconvenient truths.
First, reliable energy maintains the foundation of modern society and few are willing to give up its benefits. Access to cheap, abundant, and dependable energy has been the cornerstone of the industrial revolution and humanity’s achievements.
