Our sixth podcast in the series looks at the important role played by space-based Earth Observation. Hosts Amanda Carpenter and Alyssa Gilbert are joined by Prof. Marian Scott and Prof. Jonathan Bamber as they explain how Earth Observation combined with in-situ and sensor data provides a powerful means to observe environmental changes over space and time in unprecedented detail, even in remote parts of the globe. We find out how Earth Observation satellites are our eyes on the planet and why, without them, we would be virtually blind to the magnitude and timing of climate change and to human interference with the fragile ecosystems we all depend on.
