Some of you who follow my work know that in addition to #Arctic issues, I am also interested in outer #space. This week I came across an interesting article by researchers in Canada which is a reminder of the connection between space and polar research 1/x

2/x The abstract is available at https://www.nature.com/articles/s41561-020-0618-x (the article itself is behind a paywall). What makes this research by Grau Galofre et al. so interesting is that we can learn from research on Earth to understand space better, in this case, Mars. We now know that there...

3/x has been more water on Mars in the past. The authors show that it might be possible that some features on Mars might have been created by rivers which were flowing under glaciers. This is a process that also happens on Earth. Last year, researchers from Japan and Norway ...

4/x presented research which hints at the potential existence of a river under Greenland's inland ice https://agu.confex.com/agu/fm19/meetingapp.cgi/Paper/504281.

5/x There is still a lot to be learned and there is still so much which we don't yet know about the polar regions of Earth. Unlike Mars, the #Arctic is not an empty space but has been home to many people for thousands of years. #ClimateChange is threatening their way of life.

6/x Research happening in the Arctic therefore not only serves to increase our knowledge but can also yield practical results which matter for the people in the Arctic, for example by learning about melting ice, erosion etc. in order to prevent disasters.

7/7 Therefore, science is not an end in itself but matters in practice everyday. / END
