Climate change will have such a profound impact on the world’s wind patterns that it will change the makeup of the sand dunes near Egypt's pyramids 🔴 Exclusive BawdenTom
This is because the dunes are created by winds coming from two different directions, working in tandem. But over time, one of these winds will become much weaker, meaning the dune will effectively be blown away, according to the study.
“The western desert, west of the Nile, has a lot of the iconic sand dunes that are tens of metres tall. They are called seif dunes [seif is Arabic for sword or scimitar] and have a pattern that looks a bit like an Arabic sword,” said Andreas Baas, of King’s College London.“They are close to the pyramids and tourists often visit them together – and they’ll probably break into small sand dunes and then drift off, although it will take decades to change their shape.
“These seif dunes would effectively cease to exist and we would see a very different landscape. And that would be a pity as they’re such iconic dunes. A lot of people tend to think of the desert as an unchanging place, an eternal static environment and our studies are suggesting that this could really change in the future.”
Explaining how the dunes would gradually disappear over time, Dr Baas said: “Those seif dunes result from two seasonal winds coming from oblique directions. Our projects suggest thatone of those seasonal winds will weaken significantly in the future. And that leaves only the only the other wind that will continue blowing – so going from a wind regime of two different winds in different seasons to a wind regime with one single wind.
