Thanks to IIAS for expanding our official crew flight jacket options. I love sharing the story of our science missions and the work we do in space, and I also love that our daughters know that femininity or fun doesn’t undermine credibility and professionalism. It’s the same reason I always keep my friendship bracelets on. 🥹💕 #sparkle #femininestyle #girlhood #motherdaughter #motherhood #friendshipbracelets #pinkaesthetic

Was sind deine größten Zukunftssorgen im Bezug auf den Klimawandel? Und wie optimistisch bist du, dass wir die Erderwärmung rechtzeitig begrenzen können? Die klimapolitischen Entscheidungen in den nächsten Jahren entscheiden darüber, welche Zukunft wir erleben werden. Wenn weiter in dem Rahmen Klimaschutz betrieben wird wie bisher, wird sich die Erde bis Ende des Jahrhunderts deutlich stärker erwärmen als um 1,5 Grad. Auch unter 2 Grad würden wir dann nicht bleiben. Das hätte deutliche Konsequenzen für unsere Zukunft. Je weiter die Erwärmung voranschreitet, desto heftiger fallen diese aus. So wird es dann immer mehr Hitzewellen geben, aber auch Versorgungskrisen und einige Gebiete auf der Erde werden dann nicht mehr bewohnbar sein.
