GeoEye-1...Scheduled for launch Sept. 04, 2008. The World's Most Advanced Earth Imaging Satellite.

Mon, 01 Sep 2008 12:15:50 -0000

GeoEye-1, designed and built by General Dynamics Advanced Information Systems, is the world's highest resolution commercial imaging satellite. Designed to take color images of the Earth from 423 miles (681 kilometers) in space and moving at a speed of about four-and-a-half miles (seven kilometers) per second, the satellite will make 15 earth orbits per day and collect imagery with its ITT-built imaging system that can distinguish objects on the Earth's surface as small as 0.41-meters (16 inches) in size in the panchromatic (black and white) mode. The 4,300-pound satellite will also be able to collect multispectral or color imagery at 1.65-meter ground resolution. While the satellite will be able to collect imagery at 0.41-meters, GeoEye's operating license from NOAA requires re-sampling the imagery to half-meter resolution for all customers not explicitly granted a waiver by the U.S. Government.

StopGlobalWarming.org: At top of Greenland, new worrisome cracks in ice

At top of Greenland, new worrisome cracks in ice

by: Seth Borenstein 25 August 2008

In northern Greenland, a part of the Arctic that had seemed immune from global warming, new satellite images show a growing giant crack and an 11-square-mile chunk of ice hemorrhaging off a major glacier, scientists said Thursday.

And that's led the university professor who spotted the wounds in the massive Petermann glacier to predict disintegration of a major portion of the Northern Hemisphere's largest floating glacier within the year.

If it does worsen and other northern Greenland glaciers melt faster, then it could speed up sea level rise, already increasing because of melt in sourthern Greenland.

EX
Many extremes and their associated impacts are now changing.
For example, in recent decades most of North America has been
experiencing more unusually hot days and nights, fewer unusually cold
days and nights, and fewer frost days. Heavy downpours have become
more frequent and intense. Droughts are becoming more severe in some regions, though there are no clear trends for
North America as a whole. The power and frequency of Atlantic hurricanes have increased substantially in recent decades,
though North American mainland land-falling hurricanes do not appear to have increased over the past century. Outside
the tropics, storm tracks are shifting northward and the strongest storms are becoming even stronger.

BBC NEWS | Science/Nature | World heading towards cooler 2008

Mon, 25 Aug 2008 20:34:30 -0000

Data from the UK Met Office shows that temperatures in the first half of the year have been more than 0.1 Celsius cooler than any year since 2000.

The principal reason is La Nina, part of the natural cycle that also includes El Nino, which cools the globe.

Even so, 2008 is set to be about the 10th warmest year since 1850, and Met Office scientists say temperatures will rise again as La Nina conditions ease.

Back to the Classroom: The Forum for Education and Democracy

Fri, 22 Aug 2008 15:38:51 -0000

The chance to “make a difference” in young people’s lives is what makes teaching a calling. But working in a community of learners that prizes real intellectual development and creativity, and having a level of control over what you can do on a daily basis, is what sustains that calling.

Highlights and Sticky Notes:

Making decisions about students, teachers and schools largely on the basis of standardized test scores ultimately is detrimental to the kind of education all young people need.

These are the choices we make in the classroom that have lasting impacts on student attitude toward learning. posted by drichards

All classes will do extensive writing and revision, developing the skill of using evidence to support conclusions. The students will engage in debates, make presentations, and have varied avenues to demonstrate what they have learned and accomplished.

Beacon’s freedom from the state Regents examinations in social studies – the result of a hard-earned waiver – allows for a thematic approach and a deep exploration unconstrained by coverage considerations.

People remember 10%, 20%...Oh Really?

Fri, 22 Aug 2008 09:45:09 -0000

People do NOT remember 10% of what they read, 20% of what they see, 30% of what they hear, etc. That information, and similar pronouncements are fraudulent. Moreover, general statements on the effectiveness of learning methods are not credible---learning results depend on too many variables to enable such precision. Unfortunately, this bogus information has been floating around our field for decades, crafted by many different authors and presented in many different configurations, including bastardizations of Dale's Cone. The rest of this article offers more detail.
