U.N. climate report seeks clearer economics to guide action

By Alister Doyle, Environment Correspondent BERLIN (Reuters) - A U.N. report about ways to fix global warming due on Sunday is likely to disappoint investors seeking clear-cut economic calculations about the benefits and costs of curbing rising greenhouse gas emissions. Authors say the report stops short of an economic bottom line since it is hard to put a value, for instance, on human lives lost to extreme weather or on risks of a faster melt of Greenland's ice sheet that would push up sea levels.

Kyoto Protocol had "limited effect" on global warming: U.N. draft

A U.N. panel on climate change plans to release a report which is critical of the Kyoto Protocol aimed at curbing global warming, saying the international pact "has had limited effect on global emissions," a draft report showed Thursday. The third working group of the Intergovernmental Panel on Climate Change, which is meeting in Berlin, hopes to draw from lessons learned through the Kyoto Protocol for mapping out by 2015 a post-Kyoto framework to tackle greenhouse gas emissions.

Artificially cooling planet through geoengineering a sensitive topic for UN climate panel

BERLIN - 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.

Hollywood heavyweights put climate change manifesto on TV

By Piya Sinha-Roy LOS ANGELES (Reuters) - As temperatures continue to rise and habitats come under threat, a group of Hollywood heavyweights is seeking to bring the spotlight back on climate change with a new documentary. "Years of Living Dangerously," a nine-part documentary beginning Sunday on CBS Corp's premium cable network Showtime, chronicles the human impact on the global climate and the consequences for humans of climate change.

Carbon cuts possible for manageable warming

The world, acting urgently, can curb carbon emissions enough to avert worst-case scenarios for climate change, UN experts said Monday as envoys met in Berlin to weigh the options for action. "The literature here shows that deep cuts in greenhouse gas emissions to limit warming to 2 C... remain possible," said Ottmar Edenhofer, who helped oversee the latest volume in a report by the UN's Intergovernmental Panel on Climate Change (IPCC). But achieving this goal, Edenhofer warned, will require a break from today's relentlessly upward trend in emissions.

Governments weigh options to brake climate peril

Government envoys and scientists gathered under the UN banner in Berlin Monday to hammer out a list of options for curbing carbon emissions driving dangerous climate change. Fresh from issuing its starkest-ever warning about the impacts of global warming on Earth's weather system, the Intergovernmental Panel on Climate Change (IPCC) will meet until Friday to vet the choices meant to inform policymakers.

Time running out to meet global warming target: U.N. report

By Alister Doyle, Environment Correspondent OSLO (Reuters) - World powers are running out of time to slash their use of high-polluting fossil fuels and stay below agreed limits on global warming, a draft U.N. study to be approved this week shows. Government officials and top climate scientists will meet in Berlin from April 7-12 to review the 29-page draft that also estimates the needed shift to low-carbon energies would cost between two and six percent of world output by 2050.

Governments, scientists to debate future of fossil fuels at climate meeting

BERLIN - After concluding that global warming almost certainly is man-made and poses a grave threat to humanity, the U.N.-sponsored expert panel on climate change is moving on to the next phase: what to do about it. The Intergovernmental Panel on Climate Change, or IPCC, will meet next week in Berlin to chart ways in which the world can curb the greenhouse gas emissions that scientists say are overheating the planet. It is also trying to give estimates on what it would cost.

Climate: UN experts see options to brake juggernaut

A week after publishing the starkest warning yet on the risks of climate change, UN experts meet in Berlin from Monday to assess options for limiting the threat. A draft of the report, seen by AFP, suggests there is a 15-year window for feasible and affordable action to safely reach the UN-targeted global warming limit. But deep, swift curbs in carbon emissions will be needed, with a revolution in energy use, it says. The report is the third chapter in the Fifth Assessment Report by the Intergovernmental Panel on Climate Change (IPCC).

Governments, industry must get ready for reality of climate change, forum hears

VANCOUVER - Extreme weather events such as the flooding in Calgary and Toronto nearly kept the federal government from meeting its budget targets last year, says an insurance industry official. Barbara Turley-McIntyre of the Co-operators insurance agency told delegates at a forum on livable cities in Vancouver that the Alberta flood alone cost the Canadian economy $4.8 billion in economic losses.
