Europe is Bracing For (Another) Devastating Drought (wired.co.uk) 74

Posted by msmash from the closer-look dept.
After unusually low amounts of rain and snow this winter, the continent faces a severe water shortage. From a report: What happens during the next few months will really matter. Abundant rainfall could ease the situation and stave off the worst-case scenario. But Europe needs a lot. "We're talking about a sea, a sea's worth of water," says Hannah Cloke at the University of Reading in the UK. In terms of volume, hundreds of millions of cubic liters of rain would have to fall across the continent to fill the deficit, she estimates. It would have to amount to higher-than-average rainfall for France and certain other places, including parts of the UK. The chances of that are, unfortunately, not high.

The UK's weather agency, the Met Office, estimates there's a 10 percent chance of a wetter-than-average March, April, and May. Conversely, there's a 30 percent chance that this period will be drier than average -- and that is 1.5 times the normal chance at this time of year. The Met Office stresses that this is a "broad outlook," and there might still be patches of very wet weather even if it remains dry overall. Any rain that does fall also has to fall in the right way and in the right places. "There's always this chance that if we do get it all in two days, we see some very serious floods," says Cloke. "What we want is to see sustained, reasonably gentle rain over the next few months." Another important factor is how hot it gets this summer, says Cammalleri. Heat waves push up water consumption and increase evaporation rates. He indicates that European forecasts do not suggest that temperatures will be quite as blisteringly hot as last year -- though there is some uncertainty there too.

        I think his point is that "cubic liter" is nonsensical--"liter" is already a unit of volume. By the way, "Football fields" would be a measure of area (and, ironically, a US football field is actually a standard size as opposed to a soccer pitch which is variable) while traditionally a "library of congress" would be a measure of data capacity (or, more antiquated, linear shelf space when speaking of books) so your snark is wasted.

        A liter is a liter, be it spherical, cubic or pretty much any three-dimensional shape you could think of. It's always going to represent the same volume. It's equal to 1,000 cubic centimeters.

        Only Americans use "liters" everyone else uses "litres". Litres are a measure of volume and therefore have dimensions of length-cubed. Cubic litres, therefore, have dimensions of length to the power 9. Hence, the evidence suggests that this "UK" researcher is actually an American from the 9th dimension.

        As I understand it, there's a bit of misleadingness to the term "drought". A drought isn't over until all of the "missed" rain from the past has caught up. You can be in a period of several years of average rain and lush gardens, but if you're short from 5 years ago, you're still considered to be in a drought.

      I know this is slashdot and all but you could RTFA:

      "He estimates that reservoirs in France and northern Italy are about 40 to 50 percent lower than they should be. The longest river in Italy, the Po, is 60 percent below its normal levels. Not only that, there is roughly half the usual snow on the Alps than would be expected for this time of year. That’s a huge problem, because much of Central Europe relies on meltwater from these famous mountains every spring. “The Alps are known as the water towers of Europe for a reason,” says Cammalleri.

      France has just experienced its driest winter for 60 years. In some places, you can find extreme examples of how people have been affected. Take the village of Coucouron in the south of the country, where a truck has had to deliver drinking water up to 10 times a day since July—without any hiatus during the supposedly wetter months."

          Achhh, that idiotic stereotype has nothing to do with the matter at hand. When freight can't pass through the Rhein because the water level is too low, then billions of Euros are lost. This actually happened last summer. If farmers don't get their water allocations, as many did not in California the past few years, billions of dollars are lost and the food supply is affected. You need to be more sophisticated. Cliches have nothing to do with the intricate details of advanced capitalism. Here is another example, another contributor to the global chip supply shortage of last year was the fact that drought in Singapore had taken a couple of fabs offline becuase they were denied water. Drought doesn't manifest itself in simple stereotypes.

            You sure about Singapore having a drought last year? I kind of doubt it, since I was in Singapore for pretty much the whole of 2022, and there was zero concern about water.

            I know Taiwan had some drought issues in 2021, which may have affected fabs, but not too sure as I understand they were using water trucks to bring water to the affected fabs.

          There is a link to drought reports on that page. If you go to it and download the .pdf for Europe March 2023 you will find descriptions of substantial anomalies of low soil moisture, low river flows, and low snow packs in the mountains, in addition to things like:

          Dry conditions associated with potential impacts on water resources availability are emerging in wide areas of western and north-western Europe and several smaller areas in southern Europe. These late winter conditions are similar to the ones of 2022 wich led to severe-to-extreme drought and impacts later in that year.

          The Combined Drought Indicator (CDI) at the end of February 2023 shows widespread warning conditions for drought in southern Spain, France, Ireland, the United Kingdom, northern Italy, Switzerland, most Mediterranean island, the Black Sea regions of Romania and Bulgaria, and Greece (Fig. 1)

Close monitoring and proper water us plans are required to deal with a season that currently has high risk of that currently has a high risk of being critical for water resources.

          So it's a warning that the drought conditions of last year will probably repeat or maybe get worse.

      easy: it's not the landscape, it's always the people: drought means it doesn't rain/flow enough to satisfy the peak people's consumption in the next [arbitrary time period] in the area, so restrictions are projected to apply by [arbitrary time period] unless a solution is found and btw innovative proposals are welcome. not excluding migration, i guess, and although that's not really innovative, it is certainly disrupting.
