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.
TransCanada has filed an application running more than 30,000 pages with the country’s National Energy Board, seeking approval of the Energy East pipeline which would carry Alberta oil sands crude east, a process likely to take some 18 months, The Canadian Press reports.
A poll conducted for news organizations in South Dakota found that voters in the state –- which is in the process of renewing an expired permit for it -- overwhelmingly back the Keystone XL pipeline, although the issue does not appear on the November ballot, Gannett’s Argus Leader reports.
A Hart research poll commissioned by three environmental groups finds that 54 percent of voters surveyed in five swing states would be more likely to cast a ballot for a candidate who wants to take action against climate change, and 68 percent back one looking to expand renewable energy, The Hill reports.
Delta Airlines subsidiary Monroe Energy has written to the Surface Transportation Board -- in a letter posted online Wednesday -- complaining that delays to crude-by-rail deliveries are severely disrupting its operations, E&E reports.
Wednesday’s Federal Reserve decision to finish its asset-purchase program pumped up the dollar Thursday, which sent oil prices down. West Texas Intermediate crude for December delivery fell $1.08 to finish trading on the Nymex at $81.12 a barrel, while in London Brent lost 1 percent, or 88 cents to settle at $86.24, Bloomberg reports.
