'Modest hope' to slow warming but no 'free lunch,' U.N. warns
2014-04-14 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
CNN: Keeping global warming down to a level people can live with means cutting carbon emissions to "near zero" by the end of the century, even in an increasingly industrialized world, the top U.N. experts on the issue reported Sunday. That may be doable, but it will take "substantial investments" in everything from planting more trees to replacing fossil fuels with low-carbon power sources like solar, wind and nuclear energy, the Intergovernmental Panel on Climate Change announced in its latest report....
Catastrophic Threshold Nears and Global Warming Body Calls for Dramatic Action
2014-04-14 07:04:00| Climate Ark Climate Change & Global Warming Newsfeed
The Street: The United Nations' Intergovernmental Panel on Climate Change Sunday released the latest part of its Fifth Assessment Report, outlining the dramatic steps that need to be taken to avoid the catastrophic impacts of global warming caused by humans. Most significantly, the Summary for Policymakers portion of the report emphasizes the need for coordination on a planetary scale. "Effective mitigation will not be achieved if individual agents advance their own interests independently," the report emphasizes....

Cost of fighting warming 'modest,' says UN panel
2014-04-13 17:39:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: 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...
How to Solve Global Warming: It's the Energy Supply
2014-04-13 17:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: The world is on track for dangerous climate change, having nearly lost room for further pollution in the mix of gases that make up the atmosphere. Despite a rise in clean, renewable energy supplies in certain countries, and a partial shift from coal to natural gas in others, global greenhouse gas pollution continues to rise--and at an increasing pace in the most recent years. "Economic and population growth are drivers for emissions and they have outpaced the improvements of energy efficiency,"...

Act fast to curb global warming, or extract CO2 from air: UN
2014-04-13 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: A United Nations report said on Sunday that governments must act faster to slow global warming and delays until 2030 could force reliance on little-tested technologies to extract greenhouse gases from the air. The study, drawing on work by more than 1,000 experts, said a radical shift from conventional fossil fuels to low-carbon energy such as wind, solar or nuclear power would shave only about 0.06 percentage point a year off world economic growth. "It does not cost the world to save the planet,"...
