Guest: Robert Meisner, Earth Observation, ESA, ESRIN The Cosmic Scoop: In this eye-opening episode, Markus travels to ESRIN, ESA’s Earth Observation hub in Frascati near Rome, to sit down with Robert Meisner – a man who has spent nearly 40 years watching our planet from above. Together they dive into the hidden landscapes of the ocean surface, the secrets of gravity maps, and how satellites reveal the slow but relentless transformation of our world. From sea level rise and melting glaciers to the surreal beauty of satellite art, Robert explains why Earth observation isn’t just about data – it’s about giving our planet a voice. Along the way, he clears up climate myths, reminds us how science self-corrects, and points to the hope that comes from knowledge, action, and communication. Quotable Insights: “We deliver the hard facts – like it or not. It’s not a matter of belief, it’s a matter of measurement.”“Almost half of today’s sea level rise comes from the warming and expansion of the oceans.”“The ocean surface is not flat – it’s a landscape of invisible hills and valleys shaped by gravity.”“Science has its own cleansing system: if nobody can disprove you, chances are it matches reality.”Cosmic Timeline (Timestamps): [00:00:00] Opening: Why the ocean surface is not flat[00:03:00] What ESRIN does – ESA’s Earth Observation headquarters[00:07:00] Satellites, orbits, and why 800 km matters[00:10:00] Measuring ocean temperatures from space[00:14:00] Accuracy, salinity, and the Gulf Stream as Earth’s energy conveyor belt[00:17:30] Sea level rise – glaciers vs. thermal expansion[00:21:00] Climate denial, hard facts, and science as a self-correcting system[00:28:00] From drifting continents to ice ages – how new theories become accepted[00:29:30] The artistic beauty of satellite data[00:33:00] Melting glaciers, unstable Alps, and the thawing permafrost[00:35:00] The GOCE mission and gravity maps – why oceans have hills[00:43:00] Copernicus, Sentinel satellites, and Europe’s unique leadership[00:47:00] CO₂ monitoring from space – the upcoming game changer[00:49:00] Digital Twin Earth – simulating our planet’s future[00:50:00] The human side: 40 years of watching Earth change[00:54:00] Espresso for the mind – the art of science communicationLinks to Explore: ESA Earth Observation Copernicus ProgrammeDigital Twin Earth initiative Spread the Cosmic Love!
