📈 Across Europe, regional sea levels are rising at an average rate of 2–4 mm per year. 🌍Mean sea level change is a critical indicator of climate change, which reflects the melting of ice sheets and glaciers, which adds water to the oceans, and thermal expansion, where warming ocean waters expand in volume. 🛰️ The NASA - National Aeronautics and Space Administration data visualization below illustrates these trends. While local ocean heights fluctuate due to factors like geography, climate var
