Every day, two NASA space instruments known as the Orbiting Carbon Observatory-2 and -3 (OCO-2 and OCO-3) capture more than a million observations of sunlight reflecting off Earth's surface. Using the physics of how light travels through the air, an algorithm converts these raw data into atmospheric carbon dioxide (CO₂) concentrations.

128,000-year-old ice in Tibet could rewrite climate history

Ancient ice discovered high in Tibet may be more than 128,000 years old, preserving an extraordinary record of Earth's climate that scientists previously thought had been lost. The discovery reveals a rare glimpse into the last ice age and could reshape our understanding of how g
