It’s not really a common perspective, but I have a theory that the primary cause of especially this kind of drought has way more to do with Europe essentially draining itself through all of the river straightening projects of the 19th century. How could it not be.
Before all the industrial age river straightening that has gone on until even rather recently with damming and concrete encasement projects in I think even the 1990s, you not only prevented the river water, i.e., mountain glacial waters and evaporative rain waters from meandering and saturating the lowlands, but you even speed up the pace not to mention shortening the distance.
Sure, it wasn’t a fast process, but as anyone who has had a small water leak in their home can tell you, constant flow of water at even a small rate adds up over 24/7/365 and 200 years. You’ve literally not just been draining all your fresh water into the ocean, but you’ve been draining your water battery in the form of the saturated wetlands, soil and structures like the gravel aquifers of Central Europe of water. More people are befuddled why there is a drought after they drained the water cycle battery for 200 years, not to mention that the European population has almost quadrupled over that time and people used far less water in the past, not even to mention that the EU is doing to drive tens of millions of more people into Europe.
Ironically and in seemingly typical contradictory and counterproductive manner, the EU seems to quietly and maybe even ignorantly agree with me based on several directives and regulations they’ve been passing to restore some wetlands, river flows, and floodplains. Unfortunately it’s very little and very late (as people may be noticing) the rule of thumb is that what was destroyed takes at least 6x the effort to restore.
