U.S. greenhouse emissions fell in 2012

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.

Cost of fighting warming 'modest,' says UN panel

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.

Climate change action advocates see urgency in UN report

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.

UN panel shows who's responsible for CO2 emissions

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:

Artificial cooling tricky topic for climate panel

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.

3rd part of UN climate study to warn of rising transportation emissions


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.

UN climate panel chairs call for 'enlightenment'

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.

IPCC report suggests bioenergy to pull back greenhouse gases


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.

Jewell, Fleming spar over climate change at hearing

National Journal

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.

Figueres to industry: Leave fossil fuels and look to clean energy


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.
