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.
A 2011 study projected that the frequency and magnitude of both maximum and minimum temperatures would increase significantly as a result of global warming. [14] According to the Fifth National Climate Assessment published in 2023, coastal states including California, Florida, Louisiana, and Texas are experiencing "more significant storms and extreme swings in precipitation".
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 ...
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.
To reach either 2030 target, California carbon emissions would need to fall each year by 13.6 and 17.2 million tons of carbon dioxide equivalent per year, respectively.
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.
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 ...
In 2018, carbon dioxide was estimated to approximately be 81% of all USA greenhouse gases emitted in 2018. Natural sinks and reservoirs absorb carbon dioxide emissions through a process called the carbon cycle. Sinks and reservoirs can include the ocean, forests and vegetation, and the ground. [21]
