Icegate: Now NSIDC Caught Tampering With Climate Records


You’ve read about the climate fraud committed ‘on an unbelievable scale’ by the shysters at NASA.

You’ve read about how NOAA overestimated US warming by 50 percent.

Now it’s NSIDC’s turn to be caught red-handed fiddling the data and cooking the books.

NSIDC – National Snow and Ice Data Center – is the US government agency which provides the official statistics on such matters as sea ice coverage in the Arctic.

Naturally its research is of paramount importance to the climate alarmists’ narrative that man-made global warming is causing the polar ice caps to melt. At least it was until those ice caps refused to play ball…

Where the alarmists have for years been doomily predicting ice free summers in the Arctic –  according to Al Gore in 2007, 2008 and 2009 it would be gone by 2013 – the truth is that multi-year ice has been staging a recovery since 2009.

So what do you do if reality doesn’t suit your narrative? Simple. If you’re NSIDC (and NASA and NOAA…) you just change reality.

NSIDC’s latest attempt to breathe new life into the corpse of the alarmist narrative comprised a press release a few weeks ago claiming that 5+ year old sea ice is at its smallest level on record. To prove it, they’ve produced a new chart that looks like this.

But according to Steven Goddard of the Real Science website this claim needs to be taken with a huge pinch of salt.

Note how, to confuse matters, NSIDC have upended their chart so that 5+ year ice instead of being at the bottom is now at the top. Far worse, though, they’ve gone and deleted all the old style maps from their archive.

At least they thought they had.

But a sharp eyed reader of Goddard’s managed to find one old style map that NSIDC had forgotten to delete. This enabled Goddard to compare the new style map with an old style map for the same week. What he discovered is that NSIDC has been making some dramatic and unexplained adjustments to the record: about half the 5+ year sea ice which should be there, for example, has been mysteriously erased.

Here is a chart Goddard has composed showing the differences.

And here are the two maps, new and old. Note how much larger the 5+ year sea ice coverage is on the old one than on the new one. Note also that there is no scientific reason for this.

NSIDC must know that what they are doing is unethical. Why else would they have gone to the trouble not just of deleting their old records – but of trying to block the auto-archiving of that data?

We’re often told by the alarmist establishment that the ‘science is settled’, that there’s a 97 per cent consensus on man-made global warming and that the debate is over. Well, fine. But normally when a case is rock solid the facts are allowed to speak for themselves. Usually, the only time you need to tamper with the evidence is when you’re really desperate and when, you might say, you’re skating on really thin ice…

    1. Re graph #1: It is already strange how 4+ yr old ice can be shrinking and 2-3 yr old ice can be increasing simultaneously (approx. period 2008-2012).
    2. Of interest is also the graph that used to be published daily by the Danish Met. Inst. showing “old ice” (2+ yr) at .
    It was available until mid Jan. of this year, 2016. Updates are no longer available, in fact this graph is no longer available at all; presumably it became too controversial for NASA and NSIDC.
    This graph shows the old ice extent at the beginning of January 2016 to be substantially larger than (at the same time) in all the years 2005-2015.
    Anyone interested in a copy of this graph can contact me via the email provided at my website .
