Back to climate change. Whilst refreshing my memory about water cooling in power stations, I came across this little gem....
"water temperature is directly correlated with air temperature, with recent studies such as a 2024 research paper by Jiang Sun et al. showing a clear warming trend, as demonstrated for central Europe’s Oder (Odra) river basin. The warming rate differs per location, varying from 0.229°C to 0.720°C per decade,"
It seems that although climate change is only happening in little numbers of degrees, it matters. The above quote is in relation to power stations having to throttle their outputs during hot days, due to cooling water temperatures rising.
Rounding their numbers to 0.5 degrees per decade, that is an alarming rate of temperature rise.
It's not much of a problem for wind turbines.
