Since 1958, Keeling and his father, Charles David Keeling, have measured carbon dioxide levels at the Mauna Loa Observatory, and their work is responsible for creating the Keeling Curve, a graph ...

A cool — and frightening — illustration of rising CO2 levels. The mesmerizing animation on the right helps illustrate that even with seasonal and annual variation, the overall temperature ...

For nearly a million years, carbon dioxide levels in the atmosphere have maintained an average of about 280 ppm, not going above 300 ppm or below 160 ppm. Global warming (and cooling) trends have ...

The video depicts the concentration and movement of atmospheric CO2 from September 1, 2014 through August 31, 2015. Low levels of CO2 are shown in blue and high concentrations are indicated by ...

The claim: April 1895 v. April 2023 temperature proves CO2-driven global warming is a hoax. A tweet shows a National Oceanic and Atmospheric Administration graph with average April temperatures ...

Heat-trapping carbon dioxide levels in the air peaked in May 2021, in amounts nearly 50% higher than when the industrial age began and they are growing at a record fast rate, scientists reported ...

A misleading bar chart comparing modern carbon dioxide (CO2) levels to those millions of years before humans existed ignores a large CO2 increase during the human era that has changed the climate ...

The surge of carbon dioxide levels at the measuring station surpassed even the global average set last year, which was a record high of 419.3 ppm — 50% higher than it was before the Industrial ...

A reconstruction of 66 million years of climate history indicates global temperature may be even more sensitive to carbon dioxide levels than current models estimate.
