These people behind me should also not be walking here. This is a sandbar in the middle of the Danube River in the heart of Budapest, the capital of Hungary. And the reason we're able to do this is because the Danube here is at an all-time low ever since record-keeping began more than 200 years ago. Spin around me here. I just want to show you where the water level on a normal day during normal climate times should be. This is one of the foundations of the iconic Margaret Bridge that connects the Buda side to the Pesce side. Locals tell me that the water level normally should be two to three times my height. And this is happening up and down Europe's second longest river, which stretches something like 1,800 miles through 10 countries. For example, about 700 miles downstream from us. The bones of a woolly mammoth from the Ice Age are now being revealed. We've seen a tusk getting revealed. We've seen parts of a jawbone and a femur being revealed. Closer on in, in the country of Serbia, there is something like a couple hundred German naval vessels that have been revealed. Those were sunk by the Nazi military themselves back in 1944 when the Soviet Red Army was advancing on them. So you can see these hulking metal mammoths just coming up out of the Danube. Closer on in.
