Large archive of Canadian ice cores melts
A large archive of Canadian ice cores has been lost, melting when the freezer they were stored in failed.
The 2 April failure left “pools of water all over the floor and steam in the room,” UA glaciologist Martin Sharp told ScienceInsider. “It was like a changing room in a swimming pool.” The melted cores represented 12.8% of the collection, which held 1408 samples taken from across the Canadian Arctic. The cores hold air bubbles, dust grains, pollen, and other evidence that can provide crucial information about past climates and environments, and inform predictions about the future.
The storage facility is normally chilled to –37°C. But the equipment failure allowed temperatures to rise to 40°C, melting tens of thousands of years of history. Among the losses: some of the oldest ice cores from Mount Logan, a 5595-meter-high mountain in northern Canada. “We only lost 15 meters [of core], but because it was from the bottom of the core, that’s 16,000 years out of the 17,700 years that was originally represented,” Sharp says.
Scientists also lost 66 meters of core from Baffin Island’s Penny Ice Cap, which accounts for 22,000 years—a quarter of the record. That leaves “a gap for the oldest part, which is really the last glaciation before the warming that brought us into the present interglacial,” Sharp says.
Considering the cost and difficulty of drilling these cores, and then safely bringing them to the facility without melting, it seems to me astonishing that the facility did not have back-up freezer capability.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

I wonder how loss of some of the oldest ice samples that could show trends in ancient climates will effect the modern climate “studies”?
If the temperature went from -37 C to +40 C that wasn’t a refrigeration failure. A loss of cooling in a poorly insulated freezer should take several days (or weeks) for the temperature to reach 0 C. What no alarms like every supermarket has in its meat cooler?
Someone shut off the chiller and turned the heat up all the way. I wonder what they were trying to hide?
Any “researchers” running around that used to work at a university in East Anglia?
Of course global warming will be blamed for these cores melting.
The cores need not have melted all of the way to make them useless. The description does sound kind of fishy though.

I agree, that sounds very fishy. And given the past actions of the Warminista’s I would not be surprised to find that this was deliberate…..
