On a serious note:
I would like everyone to take a look at this clip and read the article. It reminds us why we should be aiming for sustainable design. Maybe we could challenge ourselves to come up with truly sustainable solutions when redesigning our school library.

Human-caused global warming is here: report

WASHINGTON -- Human-caused global warming is here - visible in the air, water and melting ice - and is destined to get much worse in the future, an authoritative global scientific report will warn next week.
"The smoking gun is definitely lying on the table as we speak," said top U.S. climate scientist Jerry Mahlman, who reviewed all 1,600 pages of the first segment of a giant four-part report. "The evidence ... is compelling.".....

Global warming is "happening now, it's very obvious," said Mahlman, a former director of NOAA's Geophysical Fluid Dynamics Lab who lives in Boulder, Colo. "When you look at the temperature of the Earth, it's pretty much a no-brainer."...

An early version of the ever-changing draft report said "observations of coherent warming in the global atmosphere, in the ocean, and in snow and ice now provide stronger joint evidence of warming."
And the early draft adds: "An increasing body of evidence suggests a discernible human influence on other aspects of climate including sea ice, heat waves and other extremes, circulation, storm tracks and precipitation."
The world's global average temperature has risen about 0.66 degrees Celsius from 1901 to 2005. The two warmest years on record for the world were 2005 and 1998. Last year
was the hottest year on record for the United States.
The report will draw on already published peer-review science. Some recent scientific studies show that temperatures are the hottest in thousands of years, especially during the last 30 years; ice sheets in Greenland in the past couple years have shown a dramatic melting; and sea levels are rising and doing so at a faster rate in the past decade. ...

As confident as scientists are about the global warming effects that they've already documented, they are as gloomy about the future and even hotter weather and higher sea level rises. ...

In 2001, the panel said the world's average temperature would increase somewhere between about 1.4 and 5.8 degrees Celsius and the sea level would rise between 10 and 89 centimeters by the year 2100. ...

"We have barely started down this path," said chapter co-author Richard Alley of Penn State University.
