Global warming is changing the Arctic so quickly that experts say we should expect an ice-free Arctic Ocean in the summer within just a few decades. But a group of scientists says there is a way to spare the Arctic from more disastrous climate change. In a new paper, they say that reducing global carbon emissions now could cut Arctic warming nearly in half by century's end. Society already has released enough carbon dioxide into the Earth's atmosphere that over the next few decades temperatures in the Arctic will continue to rise two to three times faster than in Earth's middle latitudes, according to the study . “Over the next 20 or 30 years, the fix is in,” said James Overland, an oceanographer at the National Oceanic and Atmospheric Administration and lead author of the scientific paper.

The California Air Resources Board thinks a little friendly competition might inspire Californians to scale back their driving, cut electricity use and take other steps to reduce carbon emissions. The agency on Thursday announced a second round of the CoolCalifornia City Challenge , where cities compete to see how much they can cut their emissions of greenhouse gases that are causing climate change. On the line is $100,000 in prize money that will go to cities based on how many people they sign up and how many points they earn in an online tracking system.

Gov. Jerry Brown's plan to provide urgently needed new funding for California's bullet train project from corporate fees on greenhouse gases melds two of his political passions: building the nation's first, truly high-speed rail system and putting the state at the forefront of the battle against global warming. The bullet train system suffered a series of legal blows last year that blocked $9 billion in state funding, sending Brown and his allies on a search for a new source of funds.

Ocean acidification could alter the behavior of fish and make them more anxious, a new study says. The finding came in an experiment by researchers interested in the neurological effects of the shift in the chemistry of seawater that is happening as the ocean takes up carbon dioxide that has built up in the Earth's atmosphere from human activity. In a laboratory, scientists put one group of young rockfish , a common species along the California coast, in normal seawater and put another group of the fish in water with the lower pH the ocean is predicted to reach in about 100 years.

Scientists sounded alarms Tuesday with a pair of studies challenging the idea that climate change is occurring gradually over the century and that its worst effects can be avoided by keeping emissions below a critical threshold. A National Research Council report says the planet is warming so quickly that the world should expect abrupt and unpredictable consequences in a matter of years or a few decades. Among the changes already underway are the sudden decline in Arctic sea ice and climbing extinction rates, the report found.

WASHINGTON - Just 90 companies worldwide produced fuels that generated two-thirds of industrial greenhouse gas emissions from 1854 to 2010, according to a new study. The 90 biggest producers of fuels driving climate change include investor-owned corporations, such as Exxon Mobil and Chevron, and state-owned oil companies, such as Saudi Aramco and Mexico's Pemex. The study attributes 914 billion metric tons of greenhouse gases to the fuels extracted by the companies, which is 63% of the total 1,450 billion metric tons of emissions estimated since the mid-19th century.
