While the worst drought since the Dust Bowl of the 1930s grips Oklahoma and Texas, scientists are warning that what we consider severe drought conditions in North America today may be normal for the continent by the mid-21^st century, due to a warming planet.

A team of scientists from the Lawrence Berkeley National Laboratory (Berkeley Lab), Lawrence Livermore National Laboratory (LLNL), and the National Oceanic and Atmospheric Administration (NOAA) came to this conclusion after analyzing 19 different state-of-the-art climate models. Looking at the balance between precipitation and evapotranspiration—the movement of water from soil to air—they found that no matter how rainfall patterns change over the next 100 years, a warming planet leads to drought. Their results were published in the December 2011 issue of the American Meteorological Society’s Journal of Hydrometerology. (more…)

RIM Continues to Lead Smartphone Market, with Apple a Close Second

Google Android Doubles its Smartphone Market Share in Past Six Months to 25 Percent

TORONTO, CA, November 30, 2011 – comScore, Inc., a leader in measuring the digital world, today released data from the comScore MobiLens service, reporting key trends in the Canada mobile phone industry for September 2011. The report ranked the leading mobile original equipment manufacturers (OEMs) and smartphone operating system (OS) platforms in Canada according to their share of current mobile subscribers ages 13 and older, and reviewed the most popular activities and content accessed via the subscriber’s primary mobile phone. The September report found Samsung to be the top handset manufacturer overall with 25.2 percent market share, while RIM led among smartphone platforms with 35.8 percent share of that market segment.

Bacterial Communication Could Affect Earth’s Climate

Woods Hole Oceanographic Institution (WHOI) scientists have discovered that bacterial communication could have a significant impact on the planet’s climate.

In the ocean, bacteria coalesce on tiny particles of carbon-rich detritus sinking through the depths. WHOI marine biogeochemists Laura Hmelo, Benjamin Van Mooy, and Tracy Mincer found that these bacteria send out chemical signals to discern if other bacteria are in the neighborhood. If enough of their cohorts are nearby, then bacteria en masse commence secreting enzymes that break up the carbon-containing molecules within the particles into more digestible bits. It has been suggested that coordinated expression of enzymes is very advantageous for bacteria on sinking particles, and Hmelo and her colleagues have uncovered the first proof of this in the ocean.

Personal Relationships Key to Successful Diplomacy: Mulroney

*Former prime minister’s speech honours Alan Gotlieb, former ambassador to U.S.*

Former prime minister Brian Mulroney, the man entrepreneur Peter Munk described as “one of our greatest statesmen,” attributed much of his success – and Canada’s under his leadership – to the personal relationships he and his ambassador cultivated with leaders south of the border.

Mulroney spoke at a University of Toronto conference, Diplomacy in the Digital Age, Oct. 13, an event held in honour of Alan Gotlieb, the former ambassador to the United States who served three prime ministers. (more…)

Oil Exploration Would Endanger The Most Biodiverse Region in The Western Hemisphere, Say Scientists

AUSTIN, Texas — An international team of scientists that includes two University of Texas at Austin researchers has found that Ecuador’s Yasuní National Park, which sits on top of massive reserves of oil, is in the single most biodiverse region in the Western Hemisphere.

The announcement is part of a final push for the Yasuní-ITT Initiative at the United Nations General Assembly. The initiative proposes that Ecuador receive compensation for half of the revenues the nation would lose by protecting the estimated 846 million barrels of oil that lie beneath the forest. (more…)

PASADENA, Calif. – A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.

The study, published online Sunday, Oct. 2, in the journal Nature, finds the amount of ozone destroyed in the Arctic in 2011 was comparable to that seen in some years in the Antarctic, where an ozone “hole” has formed each spring since the mid-1980s. The stratospheric ozone layer, extending from about 10 to 20 miles (15 to 35 kilometers) above the surface, protects life on Earth from the sun’s harmful ultraviolet rays. (more…)

Thawing Permafrost Could Release Vast Amounts of Carbon and Accelerate Climate Change by the end of this Century

*New computer modeling study, led by a Berkeley Lab scientist, could help revise understanding of permafrost’s role in global warming*

Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates.

The study also found that soil in high-latitude regions could shift from being a sink to a source of carbon dioxide by the end of the 21^st century as the soil warms in response to climate change. (more…)

ANN ARBOR, Mich.— A radical new approach to thwarting Internet censorship would essentially turn the whole web into a proxy server, making it virtually impossible for a censoring government to block individual sites.

The system is called Telex, and it is the brainchild of computer science researchers at the University of Michigan and the University of Waterloo in Canada. They will present it Aug. 12 at the USENIX Security Symposium in San Francisco. (more…)
