The Rhine is at an exceptional low – a 1-in-63-year event. Worryingly, this is a pattern: 2018, 2022 and today all rank in the top-10 lowest discharges measured at Lobith since 1901. Only November 1947 saw less water. However, modern water demand is vastly higher than it was in the winter of 1947.
Was just informed that the water level of the river Rhine has dropped too low for the official measuring point at Lobith to record it. Lobith is the critical border location where the river enters the Netherlands from Germany, serving as the primary gateway for monitoring national water inflow.
Ik heb helaas geen foto (te klein) maar Enoplognatha ovata komt in de buurt. Hij/zij leek op deze foto's, maar dan geen strepen maar een geel lijf en gele poten (dus helemaal geel), met overal zwarte stipjes, ook op de poten. Een mooi beestje.
Thanks! Google keeps telling me this is an impact crater. I think it is an archaeological feature.
Ah, but where exactly then? There are quite a few Schwendis, but Davos or Klosters is not mentioned on the map below.
A record-high ocean temperature anomaly in the central Pacific indicates the onset of an exceptionally strong El Niño. Combined with climate change, this event will trigger extreme heat, droughts and heavy rainfall worldwide, mostly impacting tropical regions and countries around the Pacific Ocean.
Lake Baikal is a rift lake and the deepest lake in the world. It is also a cryptodepression. The lake level is 455 m above sea level, its maximum depth is 1,642 m: the lowest point is 1,187 m below sea level. 7 km of sediment: the deepest continental depression. en.wikipedia.org/wiki/Cryptod...
Ireland: ‘at-risk’ drinking water supplies 💧 While over 99.8% of samples from public supplies meet safety standards, many still struggle to ensure safe and secure drinking water supply. The EPA’s Drinking Water Quality in Public Supplies Report 2025 has identified ‘at-risk’ supplies.
A remnant of a pingo, now known as Witte Veen ('white peatbog'), northeast of Grolloo, the Netherlands. Despite being forest nowadays, LIDAR still sees the traces of peat extraction (and a few old cart tracks in the south). Location: maps.app.goo.gl/b7FmodVQZB4P...
Wat doen we voor de grazers? Niets. Of ik doe thuis van achter de computer ook wat, misschien nog wel meer.
