Oak trees are dying in Norway… because of carbon starvation (lack of CO2) and inadaptation to new weather patterns

This interesting article shows that veteran oak trees are dying in Norway.

It is clearly not because of global warming since these are oaks and not spruce trees, for instance, or other coniferous. It is a result of Norway’s anti-CO2 policy with huge subsidies to electric cars.

I decided to discuss this with AI and got interesting results with ChatGPT, which focus on the hydraulic failure problem in a context of rising atmospheric CO2. It makes photosynthesis harder and explains as well the results…

Older trees : exactly what we are talking about, veteran trees are the subject of the article of Jacobsen et al.

I then wondered if the issue of the lack of rain could be explained by a lack of differential between oceanic temperatures and atmospheric temperatures (the opposite of what triggers the heavy rains in the Mediterranean). This would be caused by a lack of oceanic photosynthesis related to the endangerment of phytoplankton by aquaculture. ChatGPT actually confirms :

By asking further, ChatGPT has confirmed two things : that fjords see a particularly strong photosynthesis cooling effect because they are isolated from North Atlantic currents and that unlike coastal systems with a differential between sea and atmospheric temperatures, in fjords the conditions weaken rainfall formation.

So there is a clear, multifaceted impact in which dry conditions in oak tree forests (themselves benefitting from less CO2 fertilization) are created by a lack of convection between the fjords and lands, although here the aquaculture waste increases phytoplankton population (closer to the forests) and hence creates a stronger cooling effect that leads to less evaporation… but it’s the lack of differential of temperatures with the atmosphere that creates the drying. In other words oaks also suffer from inland temperatures that are not enough for them. Confirming that climate change is progressively reversing, slowly, step after step, in the most advanced countries, thanks to the endothermy of photosynthesis and to “cold CO2” emitted by advanced thermal motors with a high fuel efficiency. There are not enough CO2 emissions but the emissions are colder and colder with time thanks to thermal motot efficiency in advanced countries, leading to these surprising results. I asked again ChatGPT on the apparent contradiction on the role of aquaculture on phytoplankton and got all these results :

Let’s note the confirmation of the endothermic cooling effect affecting rainfalls and hence moisture levels for forests nearby

My point is that there is too much cold CO2 for these oak trees, but not enough CO2 (in general) for their growth. They are both carbon starvated and in hydraulic failure, hydraulic failure coming from the lack of sea-land gradient in relation to too much phytoplankton photosynthesis causing a lack of evaporation (since fjords are not warm enough for that). We are talking of a decline of 1,2% per year of veteran oaks in Norway and this is why these subtle microclimatic effects matter. It’s an interesting read, I think, I hope you found that as interesting as I did !
