Things are changing with global sea level data reporting. As I mentioned in my post April 6th:
As you can see in the graph above, the data has not been updated since mid 2010. Normally an update would appear sometime in Feb 2011 based on their previous update schedules.
I had sent email queries, and they went unanswered. So I made a phone call. I got an answer, described here:
The answer from the chief researcher, Dr. R. Steven Nerem, was:
“We are updating our web page to a new design, and that is the reason for the delay.”
I replied with: “OK I understand, but the SL data hasn’t been updated since mid 2010, and people are asking questions about it.”
“Well we only update a couple times per year anyway. Sea level changes pretty slowly you know.”
I said: “Yes, but in looking at your previous release schedules, you would have been due for an update in February 2011, and that hasn’t happened. “
To which he replied:
“This new website design won’t work with our current format, so if you can just be patient and wait a couple of weeks we’ll have it online.”
During the same post, in comments, Peter Miller found what might be the “new” website and commented:
Anthony, here are the updated figures – you may be using a redundant site.
A little scary as you can see ‘this new improved version’ shows a greater rate of sea level rise than previously, but most important and ominously it is clearly obvious a whole heap of data points on the chart have been/changed/manipulated/strangled.
That website had some updated “look and feel” and an updated graph, which matched the presentation of the SL graph on the http://sealevel.colorado.edu website, but the data for the graph still ended in mid 2010 even though it had a 2011_rel1 stamp on it.
I figured: “OK, they are making a new website on another server, and they are going to switch it over and redirect the DNS pointer to the new server at some point. I didn’t even bother to make a screencap of the new website since I figured it would be updated soon.
In the meantime, WUWT and CA regular, stats guy RomanM got impatient and decided to find out for himself what the most recent data looked like. He was able to locate that JASON data and plot this ensemble. Note the slight downtrend in the last year.
While that in itself doesn’t prove anything, since we have had slight short downtrends before in the satellite SL data, it was interesting in that it appears this one has been going on a bit longer.
Today I got an email from a colleague wondering “what’s going on with sea level” and saying that he too was not getting any response from Dr. Nerem regarding his email inquiries. That prompted me to check http://crozon.colorado.edu/ again, and to my suprise, I found it “forbidden”, blocked at the server:
And the main website still isn’t updated: http://sealevel.colorado.edu
But they do have this message:
2011-04-25: We are currently making improvements to this site, and a new site and sea level estimate will be released shortly. Thanks for your patience.
So, we’ll watch with anticipation to see what the new website and data might look like.
