A 2011 study projected that the frequency and magnitude of both maximum and minimum temperatures would increase significantly as a result of global warming. [13] 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".
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.
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.
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.
7 April 2022: NOAA reported an annual increase in global atmospheric methane of 17 parts per billion (ppb) in 2021—averaging 1,895.7 ppb in that year—the largest annual increase recorded since systematic measurements began in 1983. [39] The increase during 2020 was 15.3 ppb, itself a record increase. [39]
Emissions from wildfires in 2021 were ‘nearly twice’ as much CO2 as global aviation that year Wildfires released record-breaking amount of carbon dioxide in 2021 – study Skip to main content
The atmospheric concentration of carbon dioxide has increased by more than 30% since the start of the industrial age and is higher now than at any time in at least the past 650,000 years. This increase is a direct result of burning fossil fuels, broad-scale deforestation and other human activity.
A mainly coal-fueled, post-lockdown economic recovery boosted carbon dioxide emissions by 6% in 2021, the highest increase ever recorded in human history, according to a new report.
