Study: Antarctic Sea-Level Rising Faster Than Global Rate 149

An anonymous reader writes with this bit of good news for everyone who is waiting for their homes to one day be on the beach. Melting ice is fuelling sea-level rise around the coast of Antarctica, a new report in Nature Geoscience finds. Near-shore waters went up by about 2mm per year more than the general trend for the Southern Ocean as a whole in the period between 1992 and 2011. Scientists say the melting of glaciers and the thinning of ice shelves are dumping 350 billion tonnes of additional water into the sea annually. This influx is warming and freshening the ocean, pushing up its surface. "Freshwater is less dense than salt water and so in regions where an excess of freshwater has accumulated we expect a localized rise in sea level," explained Dr Craig Rye from the University of Southampton, UK, and lead author on the new journal paper.

Climate Damage 'Irreversible' According Leaked Climate Report 525

New submitter SomeoneFromBelgium (3420851) writes According to Bloomberg a leaked climate report from the IPPC speaks of "Irreversible Damage." The warnings in the report are, as such, not new but the tone of voice is more urgent and more direct than ever. It states among other things that global warming already is affecting "all continents and across the oceans," and that "risks from mitigation can be substantial, but they do not involve the same possibility of severe, widespread, and irreversible impacts as risks from climate change, increasing the benefits from near-term mitigation action."

Wow, how did this bit of nonsense get modded up.

Chinese people are generally better informed about what is going on in the world than people in most other countries.

Do you care to back this statement up? In what way are they better informed, and which countries fall into the "most other countries" category that are less informed than the Chinese public in general? I can only think of a few countries with more censorship then China.

Information that the government prohibits (child porn, holocaust denialism, videos of journalist beheadings, etc)

You're only one for three there. That's worse than dumb luck.


Cause of Global Warming 'Hiatus' Found Deep In the Atlantic 457

vinces99 writes with news about a study that may account for a slowdown in air temperature rises. Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth's surface. More than a dozen theories have now been proposed for the so-called global warming hiatus, ranging from air pollution to volcanoes to sunspots. New research from the University of Washington shows the heat absent from the surface is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle. The study is published in Science. Subsurface ocean warming explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at the Earth's surface. "Every week there's a new explanation of the hiatus," said corresponding author Ka-Kit Tung, a UW professor of applied mathematics and adjunct faculty member in atmospheric sciences. "Many of the earlier papers had necessarily focused on symptoms at the surface of the Earth, where we see many different and related phenomena. We looked at observations in the ocean to try to find the underlying cause." What they found is that a slow-moving current in the Atlantic, which carries heat between the two poles, sped up earlier this century to draw heat down almost a mile (1,500 meters). Most previous studies focused on shorter-term variability or particles that could block incoming sunlight, but they could not explain the massive amount of heat missing for more than a decade.

Scientists Baffled By Unknown Source of Ozone-Depleting Chemical 303

schwit1 writes: Scientists have found that, despite a complete ban since 2007, ozone-depleting chemicals are still being pumped into the atmosphere from some unknown source. "Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012. However, the new research shows worldwide emissions of CCl4 average 39 kilotons (about 43,000 U.S. tons) per year, approximately 30 percent of peak emissions prior to the international treaty going into effect. "We are not supposed to be seeing this at all," said Qing Liang, an atmospheric scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study published online in the Aug. 18 issue of Geophysical Research Letters, a journal of the American Geophysical Union. "It is now apparent there are either unidentified industrial leakages, large emissions from contaminated sites, or unknown CCl4 sources."

I'm sorry but you're incorrect. In 2007 Windows Mobile had the largest market share of any OS for mobile devices, with 42% of the market:

They had tied Blackberry the year before, and edged them out in 2007 which was when iPhone was released. Then the next year iPhone took over.

Going back pre-smartphone, when the only real players in the PDA arena were Palm and Microsoft, Microsoft surpassed Palm in 2004, and from then on it was all downhill for Palm as they tried to update an archaic OS to utilize advances in hardware.

Microsoft soundly won the PDA war, but then were totally decimated soon after the PDA market transitioned into the Smart Phone market. In turn, Palm, then Blackberry, then Microsoft all owned the market and then stagnated, failed to innovate, and were superseded by new OSes that didn't have legacy issues (or trying to maintain backwards compatibility, etc).

Computers are not intelligent. They only think they are.
