A new online portal and smartphone app lets Washington and Oregon residents enter the addresses of their homes, schools, workplaces or kids’ day care centers to check if they’re in harm’s way should a tsunami hit.
Materials available via the tool or phone application can be used to map out evacuation routes for you, your family, employees or students so everyone is ready when danger arises. There’s a way to create a free account so users can map and save multiple locations and evacuation routes in one place. (more…)
Long thought to produce only one generation of tree-killing offspring annually, some populations of mountain pine beetles now produce two generations per year, dramatically increasing the potential for the bugs to kill lodgepole and ponderosa pine trees, University of Colorado Boulder researchers have found.
Because of the extra annual generation of beetles, there could be up to 60 times as many beetles attacking trees in any given year, their study found. And in response to warmer temperatures at high elevations, pine beetles also are better able to survive and attack trees that haven’t previously developed defenses. (more…)
Some of the earliest humans to inhabit America came from Europe according to a new book.
Across Atlantic Ice puts forward a compelling case for people from northern Spain travelling to America by boat, following the edge of a sea ice shelf that connected Europe and America during the last Ice Age, 14,000 to 25,000 years ago.
Across Atlantic Ice is the result of more than a decade’s research by leading archaeologists Professor Bruce Bradley of the University of Exeter and Dr Dennis Stanford of the Smithsonian Institution. Through archaeological evidence, they turn the long-held theory of the origins of New World populations on its head.
For more than 400 years, it has been claimed that people first entered America from Asia, via a land bridge that spanned the Bering Sea. We now know that some people did arrive via this route nearly 15,000 years ago, probably by both land and sea. (more…)
*Outstanding educators using technology are recognized for their contribution and impact in teaching.*
REDMOND, Wash. — Aug. 1, 2011 — Microsoft Corp. today announced 11 educators from Alabama, Alaska, California, Florida, Michigan, Pennsylvania, South Carolina and Washington who have been selected as winners of the 2011 U.S. Innovative Education Forum (IEF). The IEF is an event recognizing innovative teachers and school leaders who creatively and effectively use technology in their curriculum to help improve the way kids learn while increasing student success. Out of the thousands that applied, 100 educators from 25 states were selected for a spot to compete on Microsoft’s corporate campus in Redmond. IEF participants also voted on their peers in the Educator’s Choice category and selected a winning project. The winning educators will represent the U.S. and advance to compete against educators from around the world at the Partners in Learning Global Forum, Nov. 6–11, 2011 in Washington, D.C. (more…)
The Cook Inlet Region of Alaska contains an estimated mean of 19 trillion cubic feet of natural gas, about 600 million barrels of oil, and 46 million barrels of natural gas liquids, according to a new assessment by the U.S. Geological Survey (USGS). This estimate is of undiscovered, technically recoverable oil and gas resources, and includes both unconventional and conventional resources.
These gas estimates are significantly more than the last USGS assessment of southern Alaska in 1995, in which a mean of 2.14 trillion cubic feet of gas was estimated. This increase in the undiscovered resource is attributed to new geologic information and data. (more…)
ANN ARBOR, Mich.— Melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought, according to a new study led by a University of Michigan researcher.
The 550,000-square-mile Canadian Arctic Archipelago contains some 30,000 islands. Between 2004 and 2009, the region lost the equivalent of three-quarters of the water in Lake Erie, the study found. Warmer-than-usual temperatures in those years caused a rapid increase in the melting of glacier ice and snow, said Alex Gardner, a research fellow in the Department of Atmospheric, Oceanic and Space Sciences who led the project. The study is published online in Nature on April 20. (more…)
COLUMBUS, Ohio – Despite the fears of some, a new study suggests that use of the internet in general does not make people more likely to believe political rumors.
However, one form of internet communication – e-mail – does seem to have troubling consequences for the spread and belief of rumors.
“I think a lot of people will be surprised to learn that using the internet doesn’t necessarily promote belief in rumors. Many people seem to think that’s self-evident,” said R. Kelly Garrett, author of the study and assistant professor of communication at Ohio State University. (more…)
Up to two-thirds of Earth’s permafrost likely will disappear by 2200 as a result of warming temperatures, unleashing vast quantities of carbon into the atmosphere, says a new study by the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences.
The carbon resides in permanently frozen ground that is beginning to thaw in high latitudes from warming temperatures, which will impact not only the climate but also international strategies to reduce fossil fuel emissions, said CU-Boulder’s Kevin Schaefer, lead study author. “If we want to hit a target carbon dioxide concentration, then we have to reduce fossil fuel emissions that much lower than previously thought to account for this additional carbon from the permafrost,” he said. “Otherwise we will end up with a warmer Earth than we want.” (more…)
