Pollution Does Not Change The Rate Of Droplet Formation In Clouds
Posted by redOrbit: April Flowers on February 19th, 2013
RedOrbit: A little bit of oily and viscous organic material doesn`t seem to matter much when it comes to forming the droplets that make up clouds. This is good news for reducing the uncertainty of climate model predictions.
For accurate climate modeling, understanding cloud formation is essential. This understanding has to start with droplet formation, which occurs when water vapor is attracted to particles floating in the atmosphere. These particles include dust, sea salt from the ocean, microorganisms,...

Posted by Washington Post: Juliet Eilperin on February 19th, 2013
Guardian: Indonesia is banking on an unusual strategy to prevent further flooding in its inundated capital Jakarta, and officials claim that they are already seeing positive results.
They are using 'cloud seeding' -- a weather modification technology often resorted to during drought. The method involves injecting clouds with substances that encourage the formation of ice crystals heavy enough to fall, thereby speeding up the production of rain.
Rain is the last thing that Indonesia needs now, as it has...
Oil Sands Mining Uses Up Almost as Much Energy As It Produces
Posted by InsideClimate: None Given on February 19th, 2013
InsideClimate: The average "energy returned on investment," or EROI, for conventional oil is roughly 25:1. In other words, 25 units of oil-based energy are obtained for every one unit of other energy that is invested to extract it. But tar sands oil is in a category all its own. Tar sands retrieved by surface mining has an EROI of only about 5:1, according to research scheduled to be released Tuesday. Tar sands retrieved from deeper beneath the earth, through steam injection, fares even worse, with a maximum...

Posted by AlertNet: None Given on February 19th, 2013
AlertNet: For most of his adult life, Bidur Basnet has planted paddy rice each monsoon season on his five hectares of mountain land. But in the last five years, as monsoon rains have grown increasingly unreliable, he has had to abandon the country's staple crop.
Now he grows easier-to-water vegetables on half his land, leaving the other half fallow.
"How can we prepare our paddy fields when we do not know which month in any year the monsoon rains will drench our fields?' grumbles Basnet, 43, who gave...
Texas Fracker Accused of Bully Tactics Against Foes
Posted by Washington Post: Juliet Eilperin on February 19th, 2013
Bloomberg: When a Texas landowner took his fear that a gas driller had poisoned his well to federal regulators, the company, Range Resources Corp (RRC)., turned around and sued him for conspiring “to harm Range.”
In Pennsylvania, a state lawmaker who criticized the company was dubbed “completely unhinged” by a Range representative and had his fundraising e-mails to its executives leaked to the local newspaper.
Critics say the Fort Worth-based company, which pioneered the use of hydraulic fracturing in...
‘Ice loss, weather extremes show climate risk’
Posted by Washington Post: Juliet Eilperin on February 19th, 2013
Agence France-Presse: The record shrinkage of Arctic sea ice last year and a spell of catastrophic droughts, floods and storms highlight the risk of climate change, the UN Environment Programme said yesterday.
In an annual review of the world's environment, that coincided with ministerial-level talks in Nairobi, the UN group also warned of an alarming surge in elephant and rhino poaching.
In 2012, summer sea ice in the Arctic covered a record low of 3.4million square kilometres, which was 18% below the previous...
Global standard targets water waste
Posted by Washington Post: Juliet Eilperin on February 19th, 2013
BBC: An international standard on water reduction has been launched in an effort to order to encourage businesses to use water more sustainably.
The UK's Carbon Trust, which developed the scheme, said many business leaders did not see the issue as a priority.
The Water Standard will require firms to measure water use and demonstrate efforts taken to reduce consumption.
It is estimated that more than 60% of Europe's largest cities consume water faster than it can be replenished.
UN data shows...
Study: Climate change impact on stream flow varies by location
Posted by Corvallis Gazette Times: Canda Fuqua on February 19th, 2013
Corvallis Gazette Times: The South Santiam River in southeastern Linn County dwindles to a knee-deep channel of water by late August, while the Willamette River maintains a steady and abundant flow through the summer.
In 50 to 100 years, however, warmer climate temperatures likely will have little effect on the summer flows of rivers like the South Santiam, but will impact larger, slower-draining systems such as the Willamette, according to a recent study co-authored by researchers from Oregon State University and the...

Posted by Telegraph: Brian Viner on February 19th, 2013
Telegraph: On the evening of April 18 1977, President Jimmy Carter invited television cameras into the Oval Office and portentously announced to the American people that "tonight I want to have an unpleasant talk with you about a problem unprecedented in our history. With the exception of preventing war, this is the greatest challenge our country will face during our lifetimes.'
The unprecedented problem was energy. Or rather, the lack of it. "We simply must balance our demand for energy with our rapidly...
Canada: Government Hones Oil Sands Message with Focus Groups
Posted by CBC: None Given on February 19th, 2013
CBC: Focus-group testing on what the Harper government calls its Responsible Resource Development campaign found the advertising to be light on facts but uplifting and patriotic, according to a government-commissioned study.
The fruits of that taxpayer-funded labour will again be on display this spring as a second wave of ads -- designed to persuade Canadians of "the importance and impact of Canada's energy sector" -- hits the air.
Natural Resources Canada has budgeted $9 million in the current...
