EPA Finalizes the 2008 National U.S. Greenhouse Gas Inventory
April 15, 2010 02:14 PM - Roger Greenway, ENN

The U.S. Environmental Protection Agency (EPA) has released the15th annual U.S. greenhouse gas inventory report, which shows a drop in overall emissions of 2.9 percent from 2007 to 2008. The downward trend is attributed to a decrease in carbon dioxide emissions associated with fuel and electricity consumption. An emissions inventory that identifies and quantifies a country's primary anthropogenic1 sources and sinks of greenhouse gases is essential for addressing climate change. This inventory adheres to both 1) a comprehensive and detailed set of methodologies for estimating sources and sinks of anthropogenic greenhouse gases, and 2) a common and consistent mechanism that enables Parties to the United Nations Framework Convention on Climate Change (UNFCCC) to compare the relative contribution of different emission sources and greenhouse gases to climate change.

The Dams in Montenegro

The Montenegro government was yesterday handed a 14,764 signature petition asking it to consider alternatives to its four dam plan for the country’s second most important and most scenic River. In Montenegro, Lake Skadar - a key area for biodiversity in the Balkans - is threatened by four dams planned on the Morača River. According to some studies, the dams could strongly affect the water levels in the lake hence putting a strain on its rich fish population and negatively affecting many local families who make a living from fisheries.

Global Warming: Next Chapter

For those in the American Northeast last winter was rugged and fairly cold. Yet what is he world picture? The World Meteorological Organization’s latest report demonstrates that 2000-2009 is the warmest decade since modern measurements began recording temperatures around 1850. In its annual report, “WMO Statement on the Status of the Global Climate,” the WMO also found that 2009 is nominally ranked as the fifth warmest on record.

Ancient Antarctic Air
April 13, 2010 03:51 PM - Andy Soos, ENN

A new core drilled through an ice field on the Antarctic Peninsula should contain ice dating back into the last ice age. If so, that will give new insight into past global climate changes. The expedition in early winter to the Bruce Plateau, an ice field straddling a narrow ridge on the northernmost tongue of the southernmost continent, yielded a core that was 1,462 feet long, the longest yet recovered from that region of Antarctica. Old ice can contain bubbles of trapped air from long ago. That air represents, unchanged, what the air composition was like thousands of years ago. There may be other frozen clues in the water itself

Massive Arctic Ice Cap Is Shrinking, Study Shows; Rate Accelerating Since 1985
April 13, 2010 10:15 AM - Science Daily

A paper published in the March edition of Arctic, the journal of the University of Calgary's Arctic Institute of North America, reports that between 1961 and 1985, the ice cap grew in some years and shrank in others, resulting in an overall loss of mass. But that changed 1985 when scientists began to see a steady decline in ice volume and area each year.

Glacier breaks in Peru, causing tsunami

A huge glacier broke off and plunged into a lake in Peru, causing a 75-foot (23-meter) tsunami wave that swept away at least three people and destroyed a water processing plant serving 60,000 local residents, government officials said on Monday. The ice block tumbled into a lake in the Andes on Sunday near the town of Carhuaz, some 200 miles north of the capital, Lima. Three people were feared buried in debris. Investigators said the chunk of ice from the Hualcan glacier measured 1,640 feet by 656 feet.

New climate talks set for 2010 in Cancun, Mexico
April 12, 2010 06:04 AM - Alister Doyle and Gerard Wynn, Reuters

About 175 nations agreed a plan Sunday to salvage climate talks after the Copenhagen summit but the U.N.'s top climate official predicted a full new treaty was out of reach for 2010. Delegates at the April 9-11 talks, marred by late-night wrangling between rich and poor nations on how to slow global warming, agreed to hold two extra meetings in the second half of 2010 after the December summit fell short of a binding deal. The extra sessions, of at least a week long each, and a linked plan to prepare new draft U.N. climate texts would help pave the way to the next annual meeting of environment ministers in Cancun, Mexico, November 29-December 10.

China, U.S. clash over 2010 U.N. climate talks
April 10, 2010 07:17 AM - Alister Doyle and Gerard Wynn, Reuters

The United States and China clashed on Friday about how to revive climate talks in 2010, complicating the first U.N. session since the acrimonious Copenhagen summit fell short of agreeing a treaty. Many delegates at the 175-nation talks in Bonn from April 9-11 urged efforts to restore trust between rich and poor countries but few held out hopes for a breakthrough deal to fight global warming at the next major talks in Cancun, Mexico, in late 2010. In a split between the world's top two emitters of greenhouse gases, Washington said it wanted talks in 2010 to build on a non-binding Copenhagen Accord for limiting global warming reached by more than 110 nations at the December summit.

Geologist Connects Regular Changes of Earth's Orbital Cycle to Changes in Climate
April 9, 2010 08:59 AM - Science Daily

In an analysis of the past 1.2 million years, UC Santa Barbara geologist Lorraine Lisiecki discovered a pattern that connects the regular changes of Earth's orbital cycle to changes in Earth's climate. The finding is reported in the scientific journal Nature Geoscience.

U.N. climate talks resume, little chance of 2010 deal
April 9, 2010 06:52 AM - Alister Doyle, Reuters

Climate negotiators meet in Bonn on Friday for the first time since the fractious Copenhagen summit but with scant hopes of patching together a new legally binding U.N. deal in 2010. Delegates from 170 nations gathered on Thursday for the April 9-11 meeting that will seek to rebuild trust after the December summit disappointed many by failing to agree a binding U.N. deal at the climax of two years of talks. Bonn will decide a programme for meetings in 2010 and air ideas about the non-binding Copenhagen Accord, backed by more than 110 nations including major emitters China, the United States, Russia and India but opposed by some developing states. The Accord seeks to limit world temperature rises to below 2 degrees Celsius (3.6 F), but without saying how.
