The Mauna Loa laboratory in Hawaii has measured atmospheric carbon dioxide, which — along with other planet-warming pollution ...

For 67 years, the observatory on Hawaii's Mauna Loa volcano has been taking these measurements daily  — tracking the invisible gas that is building up in our atmosphere and changing life on Earth.

New data shows that CO2 levels have broken through 430 parts per million, an indication that human-caused global warming will ...

The Keeling Curves are a set of figures nobody argues with, and everybody knows. “Our measurements have a connection for people because they’re more aware of them.

Keeling maintained this record, known as the Keeling Curve, using a running hodgepodge of short-term grants until 2005, at which point geochemist Ralph Keeling, a professor at UC San Diego’s ...

The lab is connected to the Mauna Loa Observatory, where scientists gather data to produce the Keeling Curve, a chart on the daily status of atmospheric carbon dioxide concentrations.

The latest Keeling Curve data taken at NOAA's Mauna Loa Observatory in March 2024 says that the monthly average concentration of CO2 in the atmosphere is now 4.7 parts per million (ppm) higher ...

The Keeling Curve measures the amount of carbon dioxide in the atmosphere. Scientists at Scripps Institution of Oceanography at the University of California, San Diego have been tracking these ...

The Keeling Curve documents the amount of carbon dioxide in the atmosphere every day. It also charts Antarctic ice core C02 data going back 800,000 years, long before humans appeared on the planet.
