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".
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).
The climate change policy of the United States has major impacts on global climate change and global climate change mitigation.This is because the United States is the second largest emitter of greenhouse gasses in the world after China, and is among the countries with the highest greenhouse gas emissions per person in the world.
AB 32 requires the California Air Resources Board (CARB or ARB) to create regulations and market mechanisms to reduce the state's greenhouse gas emissions to 1990 levels by 2020, a 30% statewide reduction, [3] with mandatory caps beginning in 2012 for significant emissions sources. The bill also allows the Governor to suspend the emissions caps ...
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 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 ...
California carbon emissions are falling, but not fast enough to reach the state’s 2030 climate targets, according to data released Friday by the Air Resources Board. ... year by 13.6 and 17.2 ...
Berkeley Earth is a Berkeley, California-based independent 501(c)(3) non-profit focused on land temperature data analysis for climate science.Berkeley Earth was founded in early 2010 (originally called the Berkeley Earth Surface Temperature project) to address the major concerns from outside the scientific community regarding global warming and the instrumental temperature record.
