Awesome video by Daniel Steiner about the origin of the famous Swiss topo maps. 🇨🇭🗺️

Also he’s very lucky that because of his excellent geography videos, this latest video was in collaboration with the Swiss government. (I definitely recommend subscribing to his channel.)

“[This paper] describes analysis of GNSS data showing the Earth's equator-to-pole radius difference is shrinking by ~1.8 mm/yr where previous glacial isostatic adjustment models accounted for ~0.3 mm/yr. This increasing change in the solid Earth with mass redistribution has the opposite effect on the geoid. The solid Earth is getting rounder while the geoid is becoming more oblate…”

“... PLAIN LANGUAGE SUMMARY: This study looks at how the shape of our planet is slowly changing over time. Earth is not a perfect sphere – it is slightly flattened at the poles and bulging at the equator. But this shape isn't fixed; it evolves due to natural processes like melting ice, shifting land, and changes in the Earth's surface and interior. To better understand these changes, we used satellite-based measurements of how the Earth's surface moves up or down in different places. We developed a method to analyze this data and track whether Earth is becoming more or less flattened over time. Our results indicate an acceleration of polar uplift accompanied by a comparably increasing rate of equatorial subsidence. This means that solid Earth's overall shape is becoming slightly less flattened. We further find that this geometric change is not fully mirrored in the Earth's gravity field, indicating that the geometric response of the solid Earth and the gravity field response to mass-redistribution do not evolve identically. These findings are important because they help scientists understand how the planet responds to melting glaciers and shifting water. This kind of knowledge is essential for tracking climate change and its impact on Earth's long-term behavior…”
