Some Sceptical Questions

Psychology, , , , , ,

With the able assistance of some of the regular readers of Steve Goddard’s so called “Real Science” blog I have drawn up a checklist of questions to answer should you (or any “sceptics” you may be aware of) be suffering from the delusion that the sea ice in the Arctic is “recovering” or “rebounding”:

Us:

1. Is the NSIDC daily Arctic sea ice extent number for March 8th 2014 the lowest on record for that day of the year? Yes or No?

2. Is the Cryosphere Today Arctic sea ice area number for March 8th 2014 the lowest on record for that day of the year? Yes or No?

3. Is the IJIS Arctic sea ice extent number for March 9th 2014 the lowest on record for that day of the year? Yes or No?

4. What credible evidence can you provide to show that “The Arctic is getting colder”?

5. In what way has the NSIDC’s data been “contaminated by Mann”?

6. Where might one find “empirical data that hasn’t been contaminated” if not from the likes of NOAA/NASA/JAXA et. al.

7. How do you define “The Arctic”? [2014-3-12 16:53]

8. How much sea ice do you suppose will be left in the Gulf of St. Lawrence by September? [2014-3-12 20:26]

9. Which version of “the [thickness/volume] truth” do you choose to believe? [2014-3-14 09:30]

10. When was it that the DMI “changed the way they read/interrupt coastal features [which] they incorporated into their extent/area numbers”? [2014-3-15 15:08]

11. Why have we been accused of “a lie” and “put on ignore”? [2014-3-16 15:12]

12. Please be so good as to provide us with a link that describes “the modeling used by NSIDC to ‘create’ these numbers” [2014-3-20 13:00]

No reply to any seven eight nine ten eleven of those questions as yet.

Them:

In answer to question 7 Steve Goddard “says”

NSIDC visualisation of Arctic sea ice daily extent for March 10th 2014
NSIDC visualisation of Arctic sea ice daily extent for March 10th 2014

Then a “Real Scientist” asks a sensible question:

Do NSIDC and DMI define the Arctic differently? If so, by how much?

Us:

We say:

1. Yes Dave.

2. Here’s a clue:

OSI Arctic sea ice concentration for March 11th 2014
OSI-SAF Arctic sea ice concentration for March 11th 2014

We’ll keep you posted!
