The Arctic Ice Is Thawing
Father Christmas may have to move his “workshop” from the North Pole because global warming is thawing the ice beneath his feet and his reindeers feet as well. His “workshop” is in dire straits. The “platform” for the “workshop” is melting, said Stefan Norris of the World Wildlife Fund environmental group’s Arctic Program.
An eight-nation report by 250 scientists published recently predicted the Arctic Ocean could be ice-free in summer by 2100 because of a build-up of heat-trapping gases2 in the atmosphere, mainly from burning fossil fuels in cars or factories. The North Pole is getting more and more inhabitable to Father Christmas. 46 Young people learn that Father Christmas’ “workshop” produces millions of gifts delivered by him on a flying, reindeer-drawn sleigh. Hollywood movies like “The Polar Express3” tried to make viewers believe that Father Christmas lives at the North Pole. 47
The “Fortress of Solitude” is near the North Pole that could be under threat in a warmer world5. Alan Boldt, spokesman of the Danish Ministry of Science, suggested ways to rescue Father Christmas. 48 Another alternative, he argued, would be building some electrical facilities to ensure the ice stays on the North Pole for him. “This should be a subject for the United Nations,” he said. “Denmark could build windmills to provide Father Christmas with power.” Denmark says Father Christmas’s real home is Greenland, which will help, Denmark thinks, to strengthen its position in claiming the sovereignty over the Pole. 49
“Doesn’t he already speak Danish?” Boldt said frostily when asked if Father Christmas would be forced to learn Danish if Denmark won international recognition of its claim to the Pole. Last month’s Arctic report said the region is warming twice as fast as the rest of the globe, partly because dark ground or water, once uncovered, soaks up more heat than ice or snow. Finland has been most favored by Father Christmas and it has about 500,000 tourists a year to visit its Christmas center in Rovaniemi in Lapland. 50
A. However, Nordic nations all reject it by claiming that their countries are his home.
B. Therefore the North Pole is the most attractive place in the world.
C. If Denmark’s claim were accepted internationally, it would have the legal right to search for oil and gas at the North Pole.
D. One of them would be building a giant floating ice rink for the workshop if the Pole thaws.
E. Maybe Father Christmas has already moved to Rovaniemi.
F. He may have to move from the North Pole within our children’s lifetimes.

“Liquefaction” Key to Much of Japanese Earthquake Damage
The massive subduction zone earthquake in Japan caused a significant level of soil “liquefaction” that has surprised researchers with its 51 severity, a new analysis shows.
“We’ve seen localized examples of soil liquefaction as extreme as this before, but the distance and 52 of damage in Japan were unusually severe,” said Scott Ashford, a professor of geotechnical engineering at Oregon State University. “Entire structures were tilted and sinking into the sediments,” Ashford said. “The shifts in soil destroyed water, drain and gas pipelines, crippling the utilities and infrastructure these communities need to 53 . We saw some places that sank as much as four feet.”
Some degree of soil liquefaction is common in almost any major earthquake. It’s a phenomenon in which soils soaked with water, particularly recent sediments or sand, can lose much of their 54 and flow during an earthquake. This can allow structures to shift or sink or 55 .
But most earthquakes are much 56 than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this.
“With such a long-lasting earthquake, we saw 57 structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes,” he said. “And it was clear that younger sediments, and especially areas built on 58 filled ground, are much more vulnerable.”
The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil 59 and better prepare for it in the future. Ashford said it was critical for the team to collect the information quickly, 60 damage was removed in the recovery efforts.
“There’s no doubt that we’ll learn things from what happened in Japan that will help us to reduce risks in other similar 61 ,” Ashford said. “Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns.”
Ashford pointed out that northern California have younger soils vulnerable to liquefaction-on the coast, near river deposits or in areas with filled ground. The “young” sediments, in geologic terms, may be those 62 within the past 10, 000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.
Anything 63 a river and old flood plains is a suspect, and the Oregon Department of Transportation has already concluded that 1, 100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have been reinforced to 64 collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction 65 helped prevent many buildings from collapse-even as they tilted and sank into the ground.
