1970s Spock documentary — Climate scientists believe the next ice age may have already started

Watch Spock in the 1970s describing how climate scientists were predicting a mile high wall of ice that could cover Canada down to Boston “in your lifetime”, and it may already have started. Commenter Bulldust found Gary Orsum’s droll commentary on that documentary. Great stuff.

Best part begins from 5:45 mins on:

In 1977 the worst winter in a century struck the United States… one desperate night in Buffalo, eight people froze to death…

the brutal Buffalo winter might become common all over the United States. Climate experts believe the next ice age is on its way.

Temperatures have been dropping for thirty years…

With 40 years headstart on climate scares, Orsum has all the answers.

Leonard Nimoy: Arctic cold and perpetual snow could turn most of the inhabitable portions of our planet into an Arctic wasteland.

Sure says Orsum, but there are ways to allieviate that threat even with your primitive caveman technology, just get the kids to take Fridays off school.

The opening five minutes explaining how he’s not a denier though he keeps being called one. Readers here have lived that landscape already. Just say “lukewarmer” and [...]

Surprise: Largest Glacier in Northern Hemisphere has started growing again

Jakobshavn Glacier, Greenland Image: NASA

The Jakobshavn is the glacier that dumps more ice in the ocean than any other in the Northern Hemisphere. It made the iceberg that “sank the titanic”. It has been receding for years, and the losses were accelerating, but then it astonished the scientists.

”At first we didn’t believe it,” said glaciologist Ala Khazendar of NASA’s Jet Propulsion Laboratory. “We had pretty much assumed that Jakobshavn would just keep going on as it had over the last 20 years.”

–ScienceAlert

“That was kind of a surprise. We kind of got used to a runaway system,” said Geological Survey of Denmark and Greenland ice and climate scientist Jason Box. “The good news is that it’s a reminder that it’s not necessarily going that fast. But it is going.”

Box, who wasn’t part of the study, said Jakobshavn is “arguably the most important Greenland glacier because it discharges the most ice in the northern hemisphere. For all of Greenland, it is king.”

But it’s OK, seriously, we’re all still going to bake in climate hell because all [...]

History rewritten, Global Cooling from 1940 – 1970, an 83% consensus, 285 papers being “erased”

The Global Cooling Scare of the 1970s was real, there was a consensus, and it was all over the media. It flies in the face of the man-made warming campaign. After World War II there was a massive industrial escalation in the West. And just as coal fired power was going in everywhere, the world damnwell cooled by -0.3°C. It’s obvious that the modern Climate Witches don’t want people bringing this up.

Where’s that cooling gone? The modern NASA GISS dataset adjusted it away:

What happened to 40 years of cooling from WWII onewards?

That’s the magic of homogenisation.

In 2008, Peterson, Connolley, and Fleck published “The Myth of the 1970s Global Cooling Scientific Consensus” . The Myth paper “found” that from 1965 through 1979, there were only 7 cooling, 20 neutral, and 44 warming papers. It was published in Bulletin of the American Meteorological Society (AMS), showing how pathetically weak the caliber of review is there. Kenneth Richard searched, found and documents 220 papers, not 7 in the same period. He estimates there are probably many more.

The Connolley there is none other than the William Connolly who abused Wikipedia’s editing rules — barred 2,000 other [...]

Northern Greenland warmer 1000 years ago, warmer in the 1920s too

Thanks to the Hockeyschtick for pointing us at a new study of Greenland ice cores[1]. For the first time, 12 ice cores drilled in the northern section of Greenland have been “stacked” and published. Curiously, these 12 ice cores were drilled from 1993 to 1995, so this is not new data– but it’s the first time that all 12 oxygen isotope records, which are a proxy for temperature, have been published together. The area represents about 10% of Greenland, and seems to behave differently to the southern part. The warm event in 1420 is described as a local effect. The researchers acknowledge that solar activity is important and solar activity correlates with temperatures. It must be growing more and more obvious to climate researchers that their models have to include the long term solar cycles.

The take-home messages for me are: 1/ Natural variability is big and unpredictable. 2/ When we get this kind of detail from all the continents and regions of the ocean we’ll definitely be in a position to start getting the big Global Climate Models to work. 3/ Until we figure out how the Sun causes climate change, the current models are useless.

The big picture: 65 million years of temperature swings

Greenland Interglacial Temperatures – last 10,000 years. Are we headed for an ice age? (See below for more detail.)

David Lappi is a geologist from Alaska who has sent in a set of beautiful graphs–including an especially prosaic one of the last 10,000 years in Greenland–that he put together himself (and which I’ve copied here at the top).

If you wonder where today’s temperature fits in with the grand scheme of time on Earth since the dinosaurs were wiped out, here’s the history. We start with the whole 65 million years, then zoom in, and zoom in again to the last 12,000 from both ends of the world. What’s obvious is that in terms of homo sapiens history, things are warm now (because we’re not in an ice age). But, in terms of homo sapiens civilization, things are cooler than usual, and appear to be cooling.

Then again, since T-rex & Co. vanished, it’s been one long slide down the thermometer, and our current “record heatwave” is far cooler than normal. The dinosaurs would have scoffed at us: “What? You think this is warm?”

With so much volatility in the graphs, anyone could play “pick a trend” and depending [...]
