Q: (CNN) -- A Saudi Arabian blogger detained in December, ostensibly because he supported reform advocates accused by the Saudi government of backing terrorism, has been released, a fellow blogger posted Saturday. Web sites like this one pushed for Fouad al-Farhan's release. Ahmed al-Omran said on his blog, saudijeans.org, and later told CNN that he was awakened by a text message from the wife of Fouad al-Farhan, saying he had been released and was at home with his family. "That's great news, and this is just how I wanted to start my morning," al-Omran wrote. He said he later spoke with al-Farhan for several minutes on the telephone. "He sounded fine; he seems to be in good spirits," al-Omran said. "He said he would have more to talk about later but not at this point. He said now he'd like to take some time to spend with his family, with his children that he hasn't seen for so long."  Watch al-Omran describe his conversation with al-Farhan » . A Web site set up to call for al-Farhan's release said, "Fouad is free. He is back home in Jeddah after 137 days in custody." The Saudi Interior Ministry said it had no immediate comment on the reports. In January, a ministry spokesman said al-Farhan was arrested December 10 "because he violated the regulations of the kingdom." But in an e-mail posted on al-Farhan's Web site after his arrest, he told friends that he faced arrest for supporting 10 reform advocates the Saudi government accused of backing terrorism. In the e-mail, al-Farhan said a senior Interior Ministry official promised that he would remain in custody for three days at most if he agreed to sign a letter of apology. "I'm not sure if I'm ready to do that," he wrote. "An apology for what? Apologizing because I said the government is [a] liar when they accused those guys of supporting terrorism?" Al-Farhan, who blogs at alfarhan.org, is one of the few Saudi Web commentators to use his own name, according to the U.S.-based Committee to Protect Journalists. In January, the Bush administration expressed its concerns to the Saudi government regarding al-Farhan's detention at "a relatively senior level," U.S. State Department spokesman Sean McCormack said. "The U.S. stands for freedom of expression," McCormack said at the time. "Wherever people are seeking to express themselves, via the Internet or via other areas, whether in Saudi Arabia or elsewhere in the world, we stand with that freedom of expression, and that was our message to the Saudi government." The American Islamic Congress, a U.S.-based nonprofit organization, launched an online letter-writing campaign aimed at freeing al-Farhan, whom it called "the godfather of Saudi blogging." "All he did was express his opinions in a very obvious way, and he didn't threaten anyone," al-Omran said. "He was advocating against violence and terrorism." Al-Omran said al-Farhan had stopped blogging for a few months in late 2006, after the Interior Ministry ordered him to take down a blog he was operating, but he began again at a new site. He said al-Farhan told him he was treated well in jail. He also called al-Farhan's release a turning point for the blogging community in Saudi Arabia. "It showed the community of bloggers in Saudi Arabia can come together and support this cause -- support his freedom of speech -- even those who didn't agree with some of the things he wrote," he said.

Q: (EW.com) -- The bad news: Emmy-award winning comedian John Oliver is leaving "The Daily Show," where he's been serving as a correspondent since 2006. The good news: He'll be moving to HBO for a brand-new topical comedy series, slated to launch in 2014. The show will air weekly on Sunday nights. Oliver caught the cable giant's eye this summer, when he spent two months filling in for "Daily Show" host Jon Stewart. "We weren't otherwise searching for another weekly talk show, but when we saw John Oliver handling host duties on The Daily Show, we knew that his singular perspective and distinct voice belonged on HBO," said HBO Programming president Michael Lombardo said in a statement. "We are extremely excited that John has agreed to make HBO his home." "I'm incredibly excited to be joining HBO, especially as I presume this means I get free HBO now," Oliver added. "I want to thank Comedy Central, and everyone at The Daily Show for the best seven and a half years of my life. But most of all, I'd like to thank Jon Stewart. He taught me everything I know. In fact, if I fail in the future, it's entirely his fault." See the original story at EW.com. CLICK HERE to Try 2 RISK FREE issues of Entertainment Weekly . © 2011 Entertainment Weekly and Time Inc.

Q: (CNN) -- Explorer Dennis Schmitt found an island nearly two years ago near Greenland. Fishermen pass by Greenland's Ilulissat fjord in this September 2004 picture. Such a discovery would usually elicit curiosity, even wonder perhaps, but it evoked mixed feelings for the explorer. The island was once thought to be a peninsula attached to Greenland by an ice shelf or a glacier. But such a large amount of ice melted, it revealed the distinct island. "I very quickly realized two things," he told CNN's Anderson Cooper during a visit to the island earlier this year. "One [was] that this was going to be significant because it was going to be an example of climate change." "The other thing was that it meant it was really happening. It wasn't a joke. It wasn't just statistics. It was really happening." He calls his discovery Warming Island. Many climatologists and scientists say arctic ice melt and other changes in the Earth's climate are the result of an increase in the world's temperature, a trend widely called global warming. Many global warming experts say the phenomenon, if unchecked, is capable of altering the world's climate and geography. In the worst-case scenario, experts say oceans could rise to overwhelming and catastrophic levels, flooding cities and altering seashores. Other scientists and observers, a minority compared to those who believe the warming trend is something ominous, say it is simply the latest shift in the cyclical patterns of a planet's life. Most of the scientific community believes that some warming is occurring across the globe and through some layers of the atmosphere. But why it is occurring and what that means for the future is scientifically and politically contentious. The Earth's temperature averages about 60 degrees Fahrenheit (about 16 degrees Celsius). The average surface temperature has warmed one degree Fahrenheit (0.6 degrees Celsius) during the last century, according to the National Research Council. The temperatures were relatively unchanged from 1880 to 1910, according to the U.S. Environmental Protection Agency. They rose till about 1945, cooled until about 1975 and have risen steadily to present day. There are several possible reasons for the warming, scientists say. A change in the Earth's orbit or the intensity of the sun's radiation could change, triggering warming or cooling. The reason most cited -- by scientists and scientific organizations -- for the current warming trend is an increase in the concentrations of greenhouse gases, which are in the atmosphere naturally and help keep the planet's temperature at a comfortable level. The amount of carbon dioxide in the atmosphere, for instance, has increased by 35 percent since the dawn of the industrial age, according to the United Nations' Intergovernmental Panel on Climate Change, commonly referred to as the IPCC. The presence of methane is now 151 percent above pre-industrial levels, but the rate of increase has slowed in recent decades, according to the EPA. Meanwhile, nitrous oxide increased by about 18 percent during the past 200 years. Many scientists and experts who have studied global warming believe the increase is primarily the result of human activities, like the burning of fossil fuels, emissions from vehicles and the clearing of forests. "For the last 30 years, there's no way there's anything natural that can explain it," Stephen Schneider, a professor of environmental studies at Stanford University in California, said. "A vast bulk of the knowledgeable and honest community ... will say the science is settled and humans are at least a majority of the reason behind the warming," he added. Many scientific organizations share Schneider's view, ranging from the national academies of the countries that comprise the G8 to the National Research Council, the American Meteorological Society and the American Geophysical Union. But there are those who do not share his view, and among the skeptics is Richard Lindzen, a professor of atmospheric sciences at the Massachusetts Institute of Technology. "We've suddenly taken to reading tea leaves," he said. "When we saw cooling from 1940 to 1970, we were proclaiming global cooling. Since then, there's been a few tenths of global warming, so we're proclaiming global warming." He believes the current warming trend is the result of natural variability, where a planet goes through phases of warming and cooling and the human contribution to it is minimal. "The Earth is always getting colder and warmer," he said. "It's always changing. In fact, this is true of any fluid-covered planet." Asked about glacial melt, which many observers point to as evidence of global warming, Lindzen said the way glaciers change and move are phenomena largely unexplained. "We don't know why, but it's perfectly clear that glaciers change even though the temperature is cooling at the place that they've occurred," he said. "What we're doing is cherry picking any event that occurs and then saying that's occurring due to global warming." Yet, for Schneider, it is a cause for concern and alarm. "We're already in serious melt, nobody can explain it. The models don't predict it," he said. "We don't know what's going on up there. All we know is that we could be triggering something really nasty." The greatest point of contention is the possible implications for future political and economic policies for the world's nations. The IPCC in February 2007 projected that if carbon dioxide levels doubled relative to pre-industrial levels, temperatures could rise between 3.6 to 8.1 degrees Fahrenheit (2 to 4.5 degrees Celsius) by 2100. The lower end of the range could cause more intense hurricanes, droughts, wildfires and flooding, Schneider said. The higher end could lead to the catastrophes commonly associated with the visions of Hollywood filmmakers. Uncertainties, however, plague such forecasts, which are based on computer simulations and models. The models contemplate factors associated with how the atmosphere, oceans and continents interact, all natural elements that have unpredictability intrinsic to them. "Exactly how much it's going to warm up, we don't know," Schneider said. "That it's going to warm up? I'd bet anything on that." E-mail to a friend .
