- Poll: Nation Polarized (CBS News)
Provides "The 2000 election results famously illustrated by the red and blue divisions on the election night map - delineated two very different Americas: one comprised of mainly coastal states that voted Democratic, and another, mostly in the South and Midwest, which voted Republican. Coming, as it did, after years of increasingly strained partisan divisions in Congress, it appeared that America was deeply divided - and many wonder if those patterns will repeat themselves in 2004." 7-04
- -Editorial: Overcoming Our National Polarity (NoneSoBlind.org)
Schmookler argues that "it is essential for those who oppose the forces presently ruling America to remember that the heart of the problem is not that these ruling powers are too conservative, or that they are too aligned with 'traditional' rather than 'progressive' values."
"To wage the struggle in those terms is not only to misunderstand the nature of our adversary. It is also to continue to fall into the trap that they have so successfully set for their opposition, and to abet their continuing seduction of millions of good people on the conservative side of America’s cultural divide. It is to help foster that spirit of divisiveness on which they feed."
"The heart of the problem, rather, is that these powers are not what they pretend to be. The darkness of the spirit that animates them is manifest in their ruthlessness and arrogance and dishonesty."
"Only by selling their false image of righteousness to good, conservative Americans could these forces gain power. But that which depends on moral lies can be defeated with moral truth—for, if these good people can be helped to see that these emperors have no moral clothes, they will withdraw their support." 12-05

- Polar Ocean Soaking Up Less CO2 (BBC News)
"One of Earth's most important absorbers of carbon dioxide (CO2) is failing to soak up as much of the greenhouse gas as it was expected to, scientists say."
"This effect had been predicted by climate scientists, and is taken into account - to some extent - by climate models. But it appears to be happening 40 years ahead of schedule." 05-07
- Freshwater in the Polar Ice Caps (Hypertextbook.com)
"Ice caps are found in several places in the Arctic region (Greenland, Iceland, Baffin Island, and the island of Spitsbergen) and over most of the Antarctic region. Approximately 90% of the ice on earth, is found either in Greenland or in Antarctica. The largest ice caps on the planet are found there. Greenland is a plateau surrounded by mountains. Antarctica is composed of mountains, valleys, and lowlands. From my research, I have found different values for the volume of the polar ice caps. For Antarctica, the approximate volume is 30,000,000 km3. For Greenland, it is approximately 3,000,000 km3."
"The volume of the polar ice caps is very important, because it may provide answers to future problems regarding the earth's fresh water. In the future, fresh water in the other six continents might be depleted. Since ice caps contain over 80% of the earth's fresh water, they could be used in the future to provide fresh water for earth's growing population." 07-07
- Polar Ice Caps and Rising Ocean Levels (HowStuffWorks.com)
"The main ice covered landmass is Antarctica at the South Pole, with about 90 percent of the world's ice (and 70 percent of its fresh water). Antarctica is covered with ice an average of 2,133 meters (7,000 feet) thick. If all of the Antarctic ice melted, sea levels around the world would rise about 61 meters (200 feet). But the average temperature in Antarctica is -37°C, so the ice there is in no danger of melting. In fact in most parts of the continent it never gets above freezing."
"At the other end of the world, the North Pole, the ice is not nearly as thick as at the South Pole. The ice floats on the Arctic Ocean. If it melted sea levels would not be affected."
"There is a significant amount of ice covering Greenland, which would add another 7 meters (20 feet) to the oceans if it melted. Because Greenland is closer to the equator than Antarctica, the temperatures there are higher, so the ice is more likely to melt." 07-07
- Polar Bears Going Extinct (CBS News)
"More than two-thirds of the world's polar bears will be killed off by 2050 - including the entire population in Alaska - because of thinning sea ice from global warming in the Arctic, government scientists forecast Friday." 09-07
- Polarized Lenses (Agape1.comYahoo.com)
"Polarized lenses are unique lenses that work similarly to a Venetian blind. A blind only lets in light at certain angles, which is how a polarized lens works. With the removal of the sun’s glare, objects become more distinct and are seen in their true colors. Reduced glare off water, roads, and other objects make the polarized lens a favorite for water sports, fishing, cycling and driving." 11-07
- Sarah Palin Fought Polar Bear Protections (ABC News)
"McCain's vice-presidential pick, Alaskan Gov. Sarah Palin, sued the Bush Administration in federal court recently, charging it was too accepting of climate change studies which overstated the phenomenon's impact on polar bears. The result, she argued, would be a negative impact on her state's businesses, including oil and gas extraction."
"Three of Palin's own state scientists reviewed the USGS studies and found them sound, according to internal documents released to an Alaska professor earlier this year under the state's open records law. But she has argued, in a New York Times editorial and elsewhere, that 'there is insufficient evidence that polar bears are in danger of becoming extinct in the foreseeable future.' " 09-08
- -04-14-09 Polar Melting (MSNBC News)
"At the North Pole, new satellite photos show Arctic ice is melting so fast, many scientists now predict it will be gone within 30 years. Some researchers think it could disappear in just six." 04-09
- Gore: Polar Ice May Melt Within 5-7 Years (CBS News)
"Al Gore has told the U.N. climate conference that new data suggests the Arctic polar ice cap may disappear in the summertime as soon as five to seven years from now." 12-09
- -05-24-10 Editorial: The Polarizing Role of Churches (CNN News)
"The figures underlie a striking change in the characteristics of American churches of all denominations: in the '60s, those showing up in church on Sunday might have represented a cross-section of American viewpoints; today, they are more likely to reflect traditionalist views, further driving modernists away from religion altogether - and intensifying what some have called the 'devotional divide' in American politics."
"The difference in viewpoints between traditionalists and modernists is profound - and has dramatic effects on today’s culture wars." 05-10

- -11-28-12 Political Parties Polarized on How to Avoid the "Fiscal Cliff" (CBS News)
"For a Republican lawmaker, angering the Club for Growth and other anti-tax groups could result in an influx of outside money that could sink your reelection bid. It's no wonder that when CBS News' political director John Dickerson asked a senior House leadership aide if a majority of House Republicans what the chances were that a majority of House Republicans would vote for a tax increase, the response was 'pretty close to zero.' "
"Yet House Republicans cannot simply vote against any tax hikes and be on their way. That's because if lawmakers do not take action on the 'fiscal cliff,' Americans will face a tax hike at the end of the year - when the Bush-era tax cuts, the payroll tax cut, and other ostensibly-temporary tax breaks expire. These Republicans are in a box: If they vote in favor of a deal that raises revenues, they could face a primary challenge. But if they vote against any deal, they'll be partially responsible for an across-the-board tax hike - and polling suggests Americans will place the blame largely on the GOP's shoulders. Meanwhile, Democrats have no intention of agreeing to a deal to avert the 'cliff' that does not include an increase in revenue." 11-12
- -12-01-12 Studies: Polar Ice Melting Faster (Time.com)
"The problem is that scientists have struggled to nail down just how quickly the polar ice sheets are melting. There have been more than 30 different estimates of sea level contributing due to polar ice sheet melting made since 1989. But in a new paper published in the November 29 Science, a team of researchers have gone through all of those estimates and come to a broadly agreed conclusion that melting from the ice sheets have contributed an average of 0.023 in (0.59 mm) to sea-level rise since 1992, with an uncertainty of 0.008 in. (0.2 mm) per year. That might not sound like much—ice-sheet melting has only added about half an inch (12.7 mm) to sea levels in that time span—but the new analysis means that polar ice sheets are melting three times faster today than they did in the 1990s, with much of the ice loss happening in Greenland." 12-12
- -07-24-13 Poll: Views of Zimmerman Acquittal Polarized (CBS News)
"Ten days after a Florida jury acquitted George Zimmerman in the death of Trayvon Martin, a new poll out Tuesday shows that Americans are divided about the verdict."
"Forty-one percent of those surveyed approved of the verdict and 41 percent disapproved of the jury's decision, while the rest had no opinion, according to a Washington Post-ABC News poll."
"However, 86 percent of African-Americans disapproved - with 84 percent, strongly disapproving - while 51 percent of whites approved of the verdict." 07-13
