Some comments on the "Heat wave in the Baltic Sea worries" article
Drawing inspiration from the Mediterranean SST analysis, which shed light on temperature patterns, our attention now turns to a distinct aquatic realm: the Baltic Sea. Notably, Professor Nick Kamenos at Umeå University has underscored an atypical year of heightened temperatures in this region.
Referencing the insightful article "Mediterranean Sea Temperatures: Anomalous Patterns Unveiled" (https://open.substack.com/pub/orwell2024/p/mediterranean-sea-temperatures-anomalous?utm_campaign=post&utm_medium=web), we shift our gaze towards the Baltic Sea's temperature dynamics.
However, a closer examination of the data paints a nuanced picture. Rather than exhibiting outright anomalies, the data showcases typical temporal and regional variations of non tidal enclosed seas that are inherently dominated by weather patterns. The Baltic Sea's temperature landscape is subject to a complex interplay of climatic factors that can result in noteworthy fluctuations in peak temperatures.
The article takes particular note of August 8th. For a more focused perspective, let's consider the data from the Bay of Bothnia buoy, specifically the temperature readings from this date over the last three years.
As anticipated, variations in these readings are in line with natural fluctuations. The year 2021 emerges as a standout and actually warmer than 2023.
As we've witnessed before, both buoy and satellite data can be susceptible to biases. Grasping the circumstances that give rise to these biases holds significant importance.
In the year 2022, in-situ measurements and satellite data aligned seamlessly, presenting a coherent picture. However, the landscape shifted in 2023, with noticeable disparities surfacing between the two datasets. To fortify the accuracy of our assessments, integrating handheld measurements for cross-verification would have been prudent.
A notable observation emerges when we contrast the maximum coastal temperatures reached during summer.
What stands out is that the maximum temperatures recorded in 2023 are nearly 2°C lower than those in 2021 and 1°C cooler than the preceding year. This discrepancy prompts inquiries into the core objective of this article, including the possibility of public relations being at play rather than factual science as it garnered substantial attention and citations across mainstream “worries”and alarm clickbait media.
