The latest U.S. greenhouse gas inventory shows domestic carbon emissions fell in 2012 to the lowest levels since 1994, driven by reduced energy consumption and increased use of natural gas for electricity generation.
The Environmental Protection Agency, which runs the inventory, said Tuesday that energy efficiency and a relatively warm winter also contributed to the drop of 3.4 percent in U.S. emissions compared to 2011.
BERLIN (AP) — The cost of keeping global warming in check is "relatively modest," but only if the world acts quickly to reverse the buildup of heat-trapping gases in the atmosphere, the head of the U.N.'s expert panel on climate change said Sunday.
Such gases, mainly CO2 from the burning of fossil fuels, rose on average by 2.2 percent a year in 2000-2010, driven by the use of coal in the power sector, officials said as they launched the Intergovernmental Panel of Climate Change's report on measures to fight global warming.
Without additional measures to contain emissions, global temperatures will rise about 3 degrees to 4 degrees Celsius (5 degrees to 7 degrees Fahrenheit) by 2100 compared to current levels, the panel said.
Groups seeking action to address climate change reacted Sunday to the latest report by the United Nations Intergovernmental Panel on Climate Change with a call for global leaders to reverse growing carbon emissions.
The report, released in Berlin, is the third of four that will make up the IPCC's Fifth Assessment Report, which is to set the stage for international talks next year on a global climate treaty. The report found greenhouse gas emissions accelerated from 2000-2010, growing more than in any of the previous three decades.
BERLIN (AP) — The U.N.'s expert panel on climate change is preparing a new report this weekend outlining the cuts in greenhouse gases, mainly CO2 from the burning of fossil fuels, required in coming decades to keep global warming in check.
Since it's a scientific body, the Intergovernmental Panel on Climate Change won't tell governments how to divide those emissions cuts — a crunch issue in negotiations on a new climate pact that's supposed to be adopted next year.
However, in leaked draft of the report obtained by The Associated Press, the IPCC shows with graphs and tables which countries are responsible for the greatest share of emissions, using a range of different accounting methods. These are some of the key facts on emissions:
BERLIN (AP) — It's Plan B in the fight against climate change: cooling the planet by sucking heat-trapping CO2 from the air or reflecting sunlight back into space.
Called geoengineering, it's considered mad science by opponents. Supporters say it would be foolish to ignore it, since plan A — slashing carbon emissions from fossil fuels — is moving so slowly.
The U.N.'s expert panel on climate change is under pressure from both sides this week as it considers whether geoengineering should be part of the tool-kit that governments use to keep global warming in check.
Russia, in particular, has been pushing the panel to place more emphasis on such techniques in a key document for policymakers being finalized in Berlin this week.
Greenhouse gas emissions from transportation will see the biggest increases in the coming decades, according to the third part of the study from the U.N.'s Intergovernmental Panel on Climate Change, which is due to be released April 13, Bloomberg reports.
BERLIN (AP) — The head of the United Nations scientific panel on climate change has urged governments to "exercise a high level of enlightenment" in order to bridge their differences over how to stave off the worst global warming scenarios.
Intergovernmental Panel on Climate Change chairman Rajendra Pachauri told governments and scientists on Monday that their task at the week-long meeting in Berlin is to agree on a "robust, policy-relevant and informative document" in order to keep global temperature increases below 2 degrees Celsius (3.6 F) by the end of the century.
The recent report from the U.N.'s Intergovernmental Panel on Climate Change suggests using BECCS -- bioenergy with carbon capture and sequestration -- to deal with excess greenhouse gases, although it acknowledges the technology hasn't been commercially tested, E&E reports.
Interior Secretary Sally Jewell assured Rep. John Fleming, R-La., at a House hearing on Thursday that she has no requirement that department employees agree with her view that climate change is taking place, National Journal reports.
U.N. climate chief Christiana Figueres was telling oil and gas industry figures at a London conference that they should leave most of their fossil fuel reserves alone and instead accelerate moves to clean energy, Bloomberg reports.
The U.S. Court of Appeals for the District of Columbia Circuit on Thursday lifted a stay on the Environmental Protection Agency’s implementation of its Cross-State Air Pollution Rule, although legal arguments on challenges to some aspects of the regulation are set to take place next March, E&E reports.
Producers for American Crude Exports, or PACE, for short, is made up of more than a dozen independent oil companies who would like to see the decades-old U.S. ban on crude exports overturned, Reuters reports.
The Federal Energy Regulatory Commission staff has cleared the Constitution pipeline on its environmental impact, leaving Commissioners to make the final decision on the project, which is intended to add some 650 million cubic feet of natural gas capacity in New York and New England, FuelFix reports.
If the Federal Energy Regulatory Commission approves changes that PJM Interconnection will suggest to the rules, it’s possible the wholesale electricity market manager might find a way to keep a demand response program going despite legal challenges, E&E reports.
Rising global supply and sluggish demand were continuing to weigh on oil prices. U.S. benchmark crude for December delivery dropped $1.08 to settle at $81.01 a barrel on the Nymex, $1.74 lower than the price a week ago, while Brent finished at $86.13, a loss of 70 cents on the day and 3 cents less than last Friday’s settlement price, Reuters reports.
ConocoPhillips, alongside partners including BP and Exxon Mobil, has announced what it says is the first new drilling in the North Slope’s Kuparuk River Field in nearly a dozen years, a well to come on line in 2016 that will add 8,000 barrels a day of production, Platts reports.
In one of the most hotly contested and expensive House races in the country, Rep. Nick Rahall, D-W.Va., is battling against Republican candidate Evan Jenkins and powerful conservative groups backed by the Koch brothers, The New York Times reports.
Kristin Jacobs – who has turned in a strong performance in her campaign to be elected to the Florida House of Representatives in a flood-prone Miami district – is one of a number of candidates who are successfully pressing climate change as an issue even when polls say it’s not a top voter concern, The New York Times reports.
Opower says pilot programs run in Vermont and Southern California over the summer, which involved contacting customers to ask them to go easier on their air conditioning and then reporting back to them on how much electricity they saved compared to their neighbors, cut usage by nearly 3 percent on a number of hot days, The Washington Post reports.
