Keeling Curve to GRACE: What Satellites Reveal About Earth's Changing Climate

From Mauna Loa to space, the data tell a stark story. But how did we get here? This episode of Zenith connects the birth of planets in the Orion Nebula to the instruments now tracking our own world. See how the Keeling Curve first exposed rising CO2, why early missions like Tyros-1 and Nimbus changed everything, and how GRACE measured Greenland losing 285 gigatons of ice per year while Jason-3 mapped uneven sea level rise. Follow the surprising role of Jupiter’s migration, a five-hour day on early Earth, and the Moon’s stabilizing grip that set the stage for life. Then witness the ozone hole’s discovery, the Montreal Protocol’s rare success, and today’s Copernicus data revealing shifting currents and coastlines like the Camargue retreat. We hint at why 93% of excess heat hides in the oceans and how Argo buoys uncovered a 0.9°C rise. If you want the clearest picture of climate change grounded in hard measurements, watch till the end and see what the latest records really show. #ClimateScience #KeelingCurve #GRACE #EarthObservation #SeaLevelRise #Zenith
