Carbon dioxide may be a naturally occurring substance on Earth, but too much of its presence has contributed to global ...

The latest anomaly in the climate system that can’t be fully explained by researchers is a record annual jump in the global mean concentration of carbon dioxide in the atmosphere measured in 2024.

The agency maintains the global backbone of measurements of CO2 and other gases, but these are at risk of being curtailed if ...

Over the last decade, humanity's emissions of carbon dioxide (CO₂) have stabilized after a period of huge growth. Average ...

Higher atmospheric CO2 increases the rate of photosynthesis, and thus the amount of carbohydrates in plant leaves. Sounds ...

The lack of context minimized the government’s own findings that atmospheric levels of carbon dioxide — the most abundant planet-warming gas in the air — jumped up by a record amount in 2024.

Charles David Keeling first documented how the gas buildup in the atmosphere contributes to the warming planet. His son says proposed cuts to NOAA threaten critical scientific research.
