Carbon Dioxide in the Air: Change From Past Years

CO₂ (Diff)
land NASA VEDA COG
In plain English

What it measures. Shows how carbon dioxide (CO₂) levels in the atmosphere have changed compared with previous years.

How it's made. Derived from atmospheric carbon dioxide measurements assembled into a global gridded map.

How & where you'd use it. Helps track whether and where greenhouse-gas levels are rising, informing climate monitoring and policy.
