Open letter to Andrew Bolt on real 5 metre sea rise risk : Melbourne Indymedia

This is a cautionary open letter of advice for green and red baiter Andrew Bolt there at the Herald Sun in Melbourne equivalent of the Sydney Daily Telegraph here in Sydney:

Dear Bolter

I saw you scoffing on Insiders ,

http://www.abc.net.au/insiders/

and the scoffing at your scoffing. You scorned this report carrying the picture above: page 1 The Age 2nd June 07

"Landmarks at 'high risk' from rising sea levels - National "

http://www.theage.com.au/articles/2007/06/01/1180205515091.html

Here is the bad news. Dr James Hansen of NASA (you know, the guys revered for sending man to the moon) has analysed West Antarctica and Greenland with its above sea level ice volume. His advice is that there is accelerated melting via crevasse cracks. It's 1 mm sea rise per year now but NON LINEAR. 1cm in 10years. Then quite possibly double the RATE every 10 years ie 2cms 20 years, 4cm after 30 years. Do the math, by 2100 its 5.11m sea rise. You will see it's right.

A report is here on USA Grist news site 15 May 2007

"An interview with renowned climate scientist James Hansen"

http://www.grist.org/news/maindish/2007/05/15/hansen/

To quote:

"I've actually written a paper and submitted it called "Scientific Reticence and Sea Level Rise" [PDF],

http://arxiv.org/ftp/physics/papers/0703/0703220.pdf

because it just seemed to me that there was a gap between what scientists really thought and what was in the public knowledge in regards to ice sheet stability and sea level rise."

at the pdf dated 23rd March 2007

"Under BAU forcing in the 21st century, sea level rise undoubtedly will be dominated by a third term (3) ice sheet disintegration. This third term was small until the past few years, but it is has at least doubled in the past decade and is now close to 1 mm/year, based on gravity satellite measurements discussed above. As a quantitative example, let us say that the ice sheet contribution is 1 cm for the decade 2005-2015 and that it doubles each decade until the West Antarctic ice sheet is largely depleted.

That time constant yields sea level rise of the order of 5 m this century. Of course I can not prove that my choice of a 10 year doubling time for non-linear response is accurate, but I am confident that it provides a far better estimate than a linear response for the ice sheet component of sea level rise." Dr James Hansen NASA.

The report on Grist is right next to their face to face interview with your Big Boss Rupert Murdoch on a similar topic of News Corp embracing greenhouse gas neutrality here:

"An interview with Rupert Murdoch about News Corp.'s new climate strategy" of 16th May 2007

http://www.grist.org/news/maindish/2007/05/16/murdoch/

I understand the IPCC report your quote from early this year was based on year or more old data especially omitting crevasse mechanism of accelerating melting data.

Bolter, you are sounding like Saul on the road to Damascus. Well at least Saul became Paul.

Time to stop digging Bolter.
