Mars on Ice

6 Aug 2020

At https://spaceweather.com  (3rd August 2020) .. a stream of solar wind has arrived and is causing geomagnetic  unrest around the poles. It is blowing out of a hole on the Sun's atmosphere. Meanwhile, we also have a sunspot brewing from the new solar cycle, 25. This indicates the new cycle is now alive and is popping its head above the solar minimum. Unfortunately, we have a La Nina brewing so no hope of global warming later this year.

At https://phys.org/news/2020-08-early-mars-ice-sheets-rivers.html ... early Mars was covered in ice sheets rather than flowing rivers. Researchers compared the evalley of Mars to subglacial channels in the Canadian Arctic. This uncovered striking similarities it is claimed. They actually analysed, digitally, ten thousand Martian valleys, using an algarithm to infer their underlying erosion processes. They  found only a few of the valleys matched patterns typical of surface water erosion. This is in marked contrast to the mainstream position as it currently stands.

The same story is at www.heritagedaily.com/2020/08/early-mars-was-covered-in-ice-sheets-not-f... ... and https://wattsupwiththat.com/2020/08/04/snowball-mars/ .. where geologist David Middleton says of the same study that it effectively throws cold water on the idea warm and wet conditions once existed on Mars (or the idea of a huge Martian ocean). The article comes with comments - both critical and supportive. See also https://doi.org/10.1038/s41561-020-0618-x
