Factual Accuracy Training

Published on by sunshinehours1Leave a comment

“Controversial shock jock Alan Jones has been ordered to undergo “factual accuracy” training, and to use fact-checkers, in another damaging blow to his credibility.”

“Regulators ruled that Jones breached broadcast rules by claiming Australians contributed just ”1 per cent of .001 per cent of carbon dioxide in the air.”

Aside from the scary fascist activites of the AGW crowd, keep this in mind:

 

Since the earth has not warmed for 16 years arguing about CO2 is misdirection. It doesn’t cause warming of any significance.

What did cause warming from 1980 to 1998 was in fact clean air legislation around the world.

The amount of SO2 produced by humans dropped by 1 Pinatubo volcanoes worth.

Once China’s coal burning got going, SO2 started to rise again and warming stopped.

The big lie is that exporting coal causes warming when in fact the exported coal cools the earth when it is burned.

 

Arctic Sea Ice Extent 5th Biggest Increase

Published on by sunshinehours1Leave a comment

Three days ago I did a post about it being the 8th largest refreeze at the same days as 2012.

The most recent data is from day 294 (34 days past minimum), so the post is about the most new ice from minimum to the 34th day after minimum.

2012 has moved up from 8th to 5th in terms of area, and of course it is even further ahead in percentage change at 92.7%.

Arctic Sea Ice has increased by 500,000 sq km in just 3 days.

Arctic Ice Extent – 8th Largest Refreeze Ever!

Published on by sunshinehours11 Comment

My previous post discussed the largest percentage increase in Arctic Sea Ice Extent Ever!

Some people called this bogus … since the low amount of ice made it “easy” for a large percentage increase.

However 31 days after minimum, 2012 is the 8th largest refreeze in sq km.

(Extent values in millions of sq km.)

Today is day 291 in the Arctic. The minimum in 2012 was on day 260 – 31 days ago.

If you calculate the percentage of ice gained (the refreeze) 31 days after minimum, then 2012 is the fastest refreeze ever!

Arctic Sea Ice Extent has increased by 43.8% since the minimum was reached.

Extents are in millions of sq km.

(And note I am using NSIDC data here and their algorithm is making the refreeze appear slow compared to NORSEX)

2012 Average Arctic Sea Ice Extent so far

Published on by sunshinehours1Leave a comment

Yesterday I did a post claiming average Arctic Sea Ice Extent was higher than 2007 up to day 290,

I had to issue a correction.

It turned out Arctic Sea Ice Extent was just slightly higher than 2011, but not higher than 2007.

On day 291, 2012’s lead over 2011 has shrunk from 4,633 sq km to 3393.

However, 2007’s  lead over 2012 of 1468 sq km has shrunk to 1104.

And to be clear, just because 2012 has slightly more sea ice than 2012 does not mean the end of the world happened in 2011.

The AGW cult is still quite sure we are now doomed because of the 2nd lowest amount of Arctic Sea Ice Extent (and a cyclone) occurred this year.

Updated/Corrected: Arctic Sea Ice Extent Average for 2012 is now higher than 2007 (NSIDC)

UPDATE: My apology. The original post was wrong.

What I did (in a hurry) was post the Extent for day 290, not the mean of the extent up to day 290.

Sorry.

The correct data is:

The mean for 2012 up to day 290 = 10.5267 million sq km
The mean for 2007 up to day 290 = 10.52817million sq km

2012 is still lower than 2007, but only by 1,468.4 sq km. A statistical tie.

If I had waited one more day and had done it right, the conclusion of my original post would have been right.

But it wasn’t.

However, the mean for 2011 up to day 290 is 10.522 million sq km.

Which means 2012 has now averaged 4,633.3 sq km more ice than 2011 thanks to normal extent earlier in the year.

Original Post Starts Here:

Using NSIDC data (to day 290):

The mean of Arctic Sea Ice Extent for 2012 = 5.78274 million sq km
The mean of Arctic Sea Ice Extent for 2007 = 5.74562 million sq km

The average Arctic Sea Ice Extent for 2012 is now 37,120 sq miles higher than 2007.

AGW Arctic Sea Ice Propaganda Ignores Area

Published on by sunshinehours15 Comments

AGW Arctic Sea Ice Propaganda in 4 Easy Steps with an added bonus.

The Yellow is the amount of ice where 2012 was higher than 2007.

The Pink is the amount of ice where 2007 was higher than 2012.

One of those areas is an indicator of the end of the world according to AGW. The other area is to be ignored.
