Arctic Hasn't Been This Warm in 44K Years

Maybe even far longer, according to new study

(Newser) - The Arctic's current warming trend is the worst it's experienced in at least 44,000 years—and possibly even longer—a new study has concluded. Scientists examining vegetation in the Canadian Arctic found recently-exposed moss that, based on radiocarbon dating, was between 44,000 and 51,000 years...

Obama to Bypass Congress, Put Limits on Power Plants

EPA to make announcement today

(Newser) - For the first time, the Environmental Protection Agency will set limits on the greenhouse gases power plants can emit. Today, the agency will announce that new coal plants' carbon emissions must stay below 1,100 pounds per megawatt hour, while new natural gas plants must maintain emissions below 1,000...

Scientists' $10M Goal: Burpless Cows

They'll try to cut methane emissions through selective breeding

(Newser) - A team of international scientists is going to spend $10 million to try to breed a herd of all-star cows—ones that don't burp a lot. The idea is to cut down on the cows' methane emissions, which would have a two-fold benefit, explains the Verge : It would help...

Greenhouse Gas Levels About to Hit Bad Milestone

Carbon dioxide ratio in atmosphere close to symbolic 400 parts per million

(Newser) - We're probably going to hear a lot about the "Keeling curve" and references to "400 parts per million" in the coming weeks. The curve measures the ratio of carbon dioxide in the Earth's atmosphere, and that ratio is about to cross the 400-ppm level for the...

State of the Union to Target Emissions Cuts

EPA could move to limit existing plants' greenhouse gases

(Newser) - President Obama's 2013 State of the Union address will follow up on his inaugural call to arms against climate change, insiders say. Though the specifics aren't clear yet, it's likely Obama will discuss limiting existing power plants' emissions—a plan that could depend on his use of...

Scientists Turn Air Into Gas

British company thinks it can help energy crisis in a big way

(Newser) - An amazing-sounding breakthrough from the UK: Scientists have found a way to extract carbon dioxide from air and mix it with water vapor to create a cleaner, clearer gas that can be used in existing cars and other forms of transport, reports the Independent . A company called Air Fuel Synthesis...

Ancient Romans, Chinese Helped Warm Planet

Ice samples reveal greenhouse gas emissions

(Newser) - Human activity contributed to climate change long before the Industrial Revolution, according to new research. Scientists analyzing ice core samples from Greenland found a spike in emissions of the greenhouse gas methane during a 200-year period around 2,000 years ago, when the ancient Roman and Chinese empires were at...

US CO2 Emissions Dive to 20-Year Low

Cheap natural gas has made a huge difference

(Newser) - America's carbon emissions have, amazingly, dropped to levels near where they would be in an alternate reality where President Al Gore signed the Kyoto Protocol. Emissions of the greenhouse gas are at their lowest in 20 years and government officials say the dramatic fall is thanks to cheap natural...

Carbon Dioxide Levels Pass 'Depressing' Milestone

Levels of gas in Arctic hit level not seen for 800K years

(Newser) - In a development climate scientists are calling "depressing" and "troubling"—but not the least bit surprising—the level of the main global warming pollutant has passed a new milestone. Monitoring stations all over the Arctic are measuring more than 400 parts per million of carbon dioxide in...

New Environmental Worry: Ancient Gas

Researchers now able to distinguish new, old sources of methane

(Newser) - There are huge quantities of methane locked in ice sheets around the world, threatening to speed up climate change as they get released in melting ice. But determining which methane is the ancient kind and which is much younger and hails from, say, plant life that has decayed in lakes...

West Texas scientist aims to win over skeptics

(Newser) - Who better to talk about global warming in West Texas than an evangelical Christian? That's what gives geoscientist Katharine Hayhoe an edge in her crusade to convince people around Lubbock, Texas, that greenhouse gases are harming the environment, the Miami Herald reports. "People ask me if I believe...

Global Carbon Emissions in Biggest Jump Ever

Rising greenhouse gasses will worsen climate change, say scientists

(Newser) - Carbon dioxide emissions around their world jumped by the largest amount ever last year, increasing by half a billion tons, reports the New York Times . As a percentage, the 5.9% rise was the largest since 2003 and a sign that 2009's drop of 1.4% was an aberration...

Greenhouse Gases Surging: US Report

Carbon dioxide emissions take biggest jump on record

(Newser) - Carbon dioxide, methane, and other greenhouse gases continued to build in the atmosphere last year, a federal report finds: Between 2009 and 2010, the National Oceanic and Atmospheric Administration’s yearly index of greenhouse gases—which measures said gases' combined heating effect—jumped 1.5%, to 1.29. It has...

California OKs Cap-and-Trade

Other states are watching to see how well program works

(Newser) - California became the first state in the nation to adopt its own cap-and-trade system yesterday, as its Air Resources Board voted unanimously to approve the regulations. The vote came after a grueling eight-hour meeting filled with the opinions of angry union members, disapproving industry representatives, and miscellaneous plan supporters, the...

Burning Coal Slowed Climate Change: Study

Sulfur pollution masked effect of CO2 emissions

(Newser) - The vast amounts of coal China burned during the 2000s may have actually slowed down climate change, according to a new study. Researchers believe the sulfur pollution caused by burning coal deflected the sun's rays, causing a temporary plateau in warming, the AP reports. But while sulfur drops out...

2010 Saw Shock Rise in Carbon Emissions

Experts warn consequences could be dire

(Newser) - Greenhouse gas emissions rose by a record amount in 2010, leading to the worst-ever carbon output in history, according to unpublished International Energy Agency estimates.
