Climate change causes mega-tsunami’s that shake the Earth for nine days
Every scientific curiosity becomes a climate prayer
A year ago, within an hour, 120 seismometers all over the world started to record a freakish shake every 90 seconds like a metronome. People watching the waves were baffled. And even more so that it didn’t stop within a few minutes but continued on all day and night, eventually ringing out for nine days.
It turned out to be a landslide in an oddly shaped fjord in Eastern Greenland. A 1.2 kilometre mountain of rock and ice had collapsed, sending a 110m wall of water 10 kilometers across the gorge to smash 200 metres up the other side of the fjord. The water then came back down and the return wave apparently kept slopping back and forward for nine days. Spare a thought for the fish.

Thus “10,000 swimming pools” worth of repeating tsunamis keep rattling seismic detectors for days and then kept 68 scientists busy for a year figuring out what it was.
Predictably, they say, it was caused by climate change, because rock slides and ice collapses have never happened before, or at least, not while humans had a global seismographic network.
And not a single climate model predicted this.
Apparently the Dickson fjord has a 90 degree bend at end near the mouth, and a glacial dam at the other end which stopped the energy dissipating, making it the perfect resonant chamber. Then in a freak of nature, the landslide hit at the perfect 90 degree angle in the ideal chamber to drive seismologists bonkers.
Naturally, Science, the formerly esteemed top journal had to squeeze the absurd climate propaganda near the end of the press release, so giants like The Guardian could turn it into a Shock and Awe Headline.
Experts admit their tsunami models were completely wrong, but, ooh, spooky, spooky: climate change causes “global vibrations beneath our feet”. And she’s a professor — it’s embarrassing. This is superstitious bead-wringing with mystical phrases.
Prof Anne Mangeney, a landslide modeller at the Institut de Physique du Globe de Paris in France, who was part of the team, said: “This unique long-duration tsunami challenged the classical models that we previously used to simulate just a few hours of tsunami propagation – we had to go to an unprecedentedly high numerical resolution. This opens up new avenues for tsunami modelling.”
Such events will become more common as global temperatures continue to rise. “Even more profoundly, for the first time, we can quite clearly see this event, triggered by climate change, caused a global vibration beneath all of our feet, everywhere around the world,” said Mangeney. “Those vibrations travelled from Greenland to Antarctica in less than an hour. So we’ve seen an impact from climate change impacting the entire world within just an hour.”
Holy smoke: “climate change impacts the Earth in a hour”, but we see the impact of the sun in just 8 minutes. So? Thanks to climate change, Greenland is about the same temperature now as it was in 1880.
We can’t “clearly see” any thing at all. There’s no trend, no data, no evidence. What if a warmer world means the ice doesn’t build up and go boom, but just melts away gradually. Drip, drip, drip, eh?
So the misinformation continues. In modern science lamb chops cause tsunamis, Ford F-250’s shake the world, and only solar panels can save us.
It’s all part of the hypnosis. Adults in the room need to remind the children that glaciers and rockslides have been happening for millions of years. (Eg Lieseki and Raymo) Then when kids grow up and become professors they might not say silly things.
