Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.0427%) on a molar basis in 2024, representing 3341 gigatonnes of CO 2. [1] This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. [2] [3] [4] The increase is due to human ...
Carbon emissions per capita, 2020 Carbon emissions per 1000 square miles, 2020. This is a list of U.S. states and territories by carbon dioxide emissions for energy use, [1] [2] as well as per capita [3] [4] and by area. [5] The state with the highest total carbon dioxide emissions is Texas and the lowest is Vermont.
The level of carbon dioxide increase between 2022 and 2023 was 12 percent higher than that of the last decade — and five times greater than that of the 1960s.
An alarming new report from the Scripps Institution of Oceanography shows a record-breaking amount of CO2 in our atmosphere. According to NBC, the new tests show the level of carbon dioxide, a ...
Texas has seen surging interest from companies hoping to bury carbon dioxide in its oilfields, putting the state at the vanguard of a government-subsidized program to fight climate change. But ...
Cumulatively since 1850, the U.S. has emitted a larger share than any country of the greenhouse gases causing current climate change, with some 20% of the global total of carbon dioxide alone. [10] Current US emissions per person are among the largest in the world. [11]
The sharp acceleration in CO 2 emissions since 2000 to more than a 3% increase per year (more than 2 ppm per year) from 1.1% per year during the 1990s is attributable to the lapse of formerly declining trends in carbon intensity of both developing and developed nations. China was responsible for most of global growth in emissions during this ...
