DMI’s explanation for why the altered the data. They claim the new model doesn’t change the relative positioning between years and primarily affects melt season volume.

“We have improved the DMI operational ocean and sea-ice model HYCOM-CICE with higher horizontal resolution and updated HYCOM and CICE code. In particular, the sea ice code has been greatly improved with meltponds, sea-ice salinity, improved thermodynamics and much more.

The freshwater discharge from Greenland has also been greatly improved using freshwater product from GEUS, which especially improves the coastal ocean currents and thus the ice transport nearshore Greenland. The model has been running continuously since September 1990.

The model has been running continuously since September 1990. Therefore, we have by December 07, 2021 updated the graphics of sea-ice thickness and volume using the new and improved data on Polarportal and ocean.dmi.dk.

The improved model setup has led to higher variability as well as less adrupt melting during the melt season, which gives a shift of approximately half a month for the time of minimum ice volume. The trend between the years is almost unchanged. Thereby, a year with a large sea-ice volume in the old setup also has a large volume in the new setup, and similar for years with low sea-ice volume.”

The “new and improved” version put 2021 below the 2004-2013 mean, below 2017 and below 2018. The two years which saw a large reduction in December volume were 2020 and 2021. There aren’t any melt ponds in December. The 2004-2013 mean, and 2017, 2018, 2019 didn’t change significantly – but 2020 and 2021 dropped sharply.

There was very little change to the 2021 summer volume, but lots of change to the winter volume.  The is the opposite of other years and the opposite of their description of the changes.

The changes they made occurred during winter, not summer. It appears they rotated the 2021 data several degrees clockwise, which brought spring volume up and winter volume down.

The sailors are trapped in the ice because of an early freeze up, and DMI has altered the data to show the exact opposite.

The 2017 data is rotated counter-clockwise in the new version, but the 2021 data is rotated the other direction. Their changes aren’t credible and are a complete mess.

Golf courses are destroying the planet. They are going to turn into bone-dry muddy swaps due to climate change.

Berkeley experts say there are too many coyotes in town due to fires caused by climate change.

Sixty years ago, Berkeley experts said there were too few coyotes in town because of hunting, trapping and poisons.

On this date in 1943, there were catastrophic fires in Berkeley – apparently not caused by climate change.

In 2012, I caught NSIDC cheating, just as Arctic sea ice extent was about to cross above the 1979-2000 average. They changed their measurement system using a completely bogus mathematical trick. NSIDC argued with me about it for a while, and eventually admitted that their nature trick was garbage.

NSIDC’s 2012 Nature Trick | Real Science

They have done a much bigger cheat this time, in order to generate this propaganda:

ice at least 5 years or older, is at its smallest level in the satellite record, representing only 3 percent of the total ice cover

From week 1 1984 to week 37, 2015 NSIDC generated ice age maps in this format:

ftp://ccar.colorado.edu/pub/tschudi/iceage/gifs/

Week 38 (late September) is the week when the ice has its birthday, and all of the ice advances one year. I generated the map below of what week 38 should have looked like, based on advancing the ice age one year. There should have been a large increase in 5+ ice, because all of the 4 year old ice became five year old ice on week 38.

However, that didn’t happen. What they did was change to a new set of maps on week 39, and actually deleted the directory containing the 1984-2015 maps.  They never generated a week 38 map. Very naughty.

A large area of four year old ice not only didn’t age, but it disappeared entirely.

The animation below shows what the map should have looked like compared to what it does look like. They massively reduced the amount of five year old ice that should have been present in the map.

The graph below shows the sum total of they did. When they switched maps, they decreased the amount of 3, 4 and 5+ year old ice, and increased the amount of two year old ice.

Not only did they they alter the data, but they also deleted the evidence. And to make matters worse, they blocked auto archiving of the 1984-2015 data.

The data is not lost however. I have all their old maps archived here. Did they really think I wasn’t going to catch them?

Is it strong enough to survive a one part per ten thousand increase in CO2 over the past century?
