A study published in Science Advances in 2022 stated that climate-caused changes in atmospheric rivers affecting California had already doubled the likelihood of megafloods since 1920—which can involve 100 inches (250 cm) of rain and/or melted snow in the mountains per month, or 25 to 34 feet (7.6 to 10.4 m) of snow in the Sierra Nevada—and ...
Since January 2009, all new vehicles sold in California have been required to be labeled with a California Air Resources Board window sticker showing both a Smog Score and a Global Warming Score. The scores are on a 1–10 scale, with 5 being average and with 10 being the best (i.e., emitting the least carbon dioxide).
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.
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.
Kern County has signed off an oil company's plan to permanently store greenhouse gas emissions underground in a depleted oil field, marking California's first foray into carbon storage and a ...
California Executive Order B-30-15 [13] (April 2015, signed by Governor Jerry Brown) added the intermediate target of: By 2030, reduce GHG emissions to 40 percent below 1990 levels. This intermediate target was codified into law by SB 32, which was signed into law by Governor Jerry Brown on September 8, 2016.
The proposed changes to California's influential Low Carbon Fuel Standard (LCFS), which has been in place since 2011, would require a deeper reduction in the carbon intensity of transportation ...
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.
