An Interesting Interview on David Letterman

here comes the flood of deniers and haters...

I like how realistic Dave was in the video. He pointed out some real issues and even if he was 'half right' he was right enough to pretty much kill an optimistic view of the subject heh heh

30 years ago Carter installed solar panels on the White House.

Reagan immediately removed them.

Who controls Washington again?

You don't have to deny or be a hater to see he's just sitting there to sell a commercial product, being that book. :2 cents:

People sell bibles too, so go figure... :2 cents:

Your point?

My point is, diminishing the value of a book, based upon the throw-away statement that it has commercial value, is patently absurd, as ALL books are for sale.

Does Newt Gingrich sell books? How about Sarah Palin?

By the same logic, then none of their books should be taken seriously either.

Hence the bible reference.

It seemed quite succinct to me - I didn't realize it required further explanation.

its quite obvious the guy didnt come there to sell a book but to advertise the movement 10 10 10. gah i hope they put some money into research for neutralizing carbon real soon. -_-

You are obviously his target demographic. :2 cents:

Yes, I am part of the dreaded "People Who Comprehend and Acknowledge Obvious Scientific Facts" demographic, that he is likely targeting.

Guilty as charged! :thumbsup

ive always wondered about huge air filters...almost like fans...to suck the air through them,
then those filters get ground up and turned into fertilizer etc

i mean huge..like mandatory the 22-28 th floors on all tall rises in manhattant or what not be filters...the say three floors high

im guessing if enough large fans were setup the cities at least might be less smoggy
and identifying routes of air travel might allow you to tap into areas that need to be cleaned

I still fail to see how my suicide will improve anything...

even letterman thinks Barry will be a one term president

Well, that proves it then! Good catch!

the climate has obviously changed ...

If only it were just that easy!

By the way, here is a link correction for you...

Why do we continue to hear the scare stories about Antarctic ice when its breaking records for ice growth? Not only is the interior growing but so is the sea ice. Sea ice levels are higher now than when satellite records began.

Antarctic Ice Extent and Concentration for October 1979 and October 2008

From the National Snow and Ice Data Center, University of Colorado

Note that the ice extent for October 1979 (when satellite measurements began) is 18 million sq km, for October 2008 the ice extent was 18.1 million sq km. Ice concentration shows even greater increases, from 13.6 million sq km, to 13.9 million.

Not a huge increase but certainly notable since everyone has been screaming about Antarctic ice melt off, obviously that is not happening. Interior ice is increasing at an even greater rate. According to NOAA GISS data winter temperatures in the antarctic has actually fallen by 1°F since 1957, with the coldest year being 2004. All the while global CO2 levels have gone up and the main stream media has been reporting near catastrophic warming conditions. The MSM and certain segments of the scientific community truly must have no shame.

NOW, BACK TO REALITY...

Arctic sea ice thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record. The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover.

Scientists from NASA and the University of Washington in Seattle conducted the most comprehensive survey to date using observations from NASA's Ice, Cloud and land Elevation Satellite, known as ICESat, to make the first basin-wide estimate of the thickness and volume of the Arctic Ocean's ice cover. Ron Kwok of NASA's Jet Propulsion Laboratory in Pasadena, Calif., led the research team, which published its findings July 7 in the Journal of Geophysical Research-Oceans.

The Arctic ice cap grows each winter as the sun sets for several months and intense cold ensues. In the summer, wind and ocean currents cause some of the ice naturally to flow out of the Arctic, while much of it melts in place. But not all of the Arctic ice melts each summer; the thicker, older ice is more likely to survive. Seasonal sea ice usually reaches about 2 meters (6 feet) in thickness, while multi-year ice averages 3 meters (9 feet).

Using ICESat measurements, scientists found that overall Arctic sea ice thinned about 0.17 meters (7 inches) a year, for a total of 0.68 meters (2.2 feet) over four winters. The total area covered by the thicker, older "multi-year" ice that has survived one or more summers shrank by 42 percent.

Previously, scientists relied only on measurements of area to determine how much of the Arctic Ocean is covered in ice, but ICESat makes it possible to monitor ice thickness and volume changes over the entire Arctic Ocean for the first time. The results give scientists a better understanding of the regional distribution of ice and provide better insight into what is happening in the Arctic.

"Ice volume allows us to calculate annual ice production and gives us an inventory of the freshwater and total ice mass stored in Arctic sea ice," said Kwok. "Even in years when the overall extent of sea ice remains stable or grows slightly, the thickness and volume of the ice cover is continuing to decline, making the ice more vulnerable to continued shrinkage. Our data will help scientists better understand how fast the volume of Arctic ice is decreasing and how soon we might see a nearly ice-free Arctic in the summer."

In recent years, the amount of ice replaced in the winter has not been sufficient to offset summer ice losses. The result is more open water in summer, which then absorbs more heat, warming the ocean and further melting the ice. Between 2004 and 2008, multi-year ice cover shrank 1.54 million square kilometers (595,000 square miles) -- nearly the size of Alaska's land area.

During the study period, the relative contributions of the two ice types to the total volume of the Arctic's ice cover were reversed. In 2003, 62 percent of the Arctic's total ice volume was stored in multi-year ice, with 38 percent stored in first-year seasonal ice. By 2008, 68 percent of the total ice volume was first-year ice, with 32 percent multi-year ice.

"One of the main things that has been missing from information about what is happening with sea ice is comprehensive data about ice thickness," said Jay Zwally, study co-author and ICESat project scientist at NASA's Goddard Space Flight Center in Greenbelt, Md. "U.S. Navy submarines provide a long-term, high-resolution record of ice thickness over only parts of the Arctic. The submarine data agree with the ICESat measurements, giving us great confidence in satellites as a way of monitoring thickness across the whole Arctic Basin."

The research team attributes the changes in the overall thickness and volume of Arctic Ocean sea ice to the recent warming and anomalies in patterns of sea ice circulation.

"The near-zero replenishment of the multi-year ice cover, combined with unusual exports of ice out of the Arctic after the summers of 2005 and 2007, have both played significant roles in the loss of Arctic sea ice volume over the ICESat record," said Kwok.
