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.
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 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.
The increase in average ... with its boreal forests pulling carbon dioxide ... US coastal cities from Boston to San Diego have seen more and more flood days per year every decade since 1950, ...
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 atmospheric burden of greenhouse gases due to human activity has grown especially rapidly during the last several decades (since about year 1950). For carbon dioxide, the 50% increase (C/C 0 = 1.5) realized as of year 2020 since 1750 corresponds to a cumulative radiative forcing change (delta F) of +2.17 W/m 2. [6]
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 ...
