ESA astronaut Thomas Pesquet admiring Earth's oceans from the Cupola of the International Space Station.
Thomas shared this image on his social media channels with the caption: "I have always believed it is best to listen to scientists and experts on topics. A unique digital conference is starting today where scientists from all over the oceans propose solutions and present their latest findings in the run up to the United Nations climate change conference. All waters are connected, and from space you can see that no maps do our planet justice: we really are an ocean planet. Oceans form a huge part of our ecosystem. There are 7 people in space right now, 7 billion people on Earth, but many more living organisms in the oceans by far, without them climate change would be worse. To protect it, we must understand it."
