We may be living through some of the best weather in the last 100,000 years

Kenneth Richard at NoTricksZone reports on a new paper showing the incredible extreme climate shifts of Greenland. During the depths of the last ice age Greenland temperatures would swing abruptly by 10 to 15 degrees Celsius (or 30F) in the space of 30 years. And we’re panicking at the moment about warming at 0.13°C per decade.

These Dansgaard–Oeschger (D–O) events occurred 24 times from 120,000 years ago until 11,000 years ago. There were no humans living there at the time, as far as we know. The best estimate is that people first arrived in Greenland 4,500 years ago. As far as we know, it’s only Greenland that was gyrating wildly in temperature but the bare truth about climate scientists is the expert models can’t predict or explain any of this. So the seismic shifts came and went and went and came, and it had nothing to do with whether you turned the airconditioner on.

If any poor sodding homo sapiens did manage to wash up on Greenland during the peaks 30 or 40,000 […]

This new study pokes holes in the dogma five different ways

Bones in a cave inside the Arctic circle show that the world was hotter, the climate is always changing, and life adapts very well.

A special cave in far northern Norway has a a trove of thousands of old bones. They are deposited in layers that stretch back from 5,800 years ago to 13,000 years ago. And it’s been a radical change: at the start, the cave was submerged under the ocean, so the bones are mostly marine species. But a few thousand years later the weather was warm, and birds and mammals had moved in. By 6,000 years ago the researchers estimate it was the hottest part of the Holocene and 1.5°–2.4°C warmer than the modern era of 1961–1990.

After that, the cave was blocked by scree, and the bone fragments sat there seemingly undisturbed for nearly 6,000 years while the ice sheets moved and the Vikings came and went and the world cooled. Then in 1993 someone happened to build a road nearby and found the cave. Now a team […]

Only 6,000 years ago the world was warmer and the Sahara was lush green and wet

New Study Finds The Early-Mid Holocene Sahara Had Lakes With Depths Of ‘At Least 300 Meters’

During the hottest part of the Holocene, for thousands of years, there were deep lakes filled with water in the middle of the Sahara Desert. From 9,500 years ago to 6,000 years ago the monsoons rained on the Sahara, freshwater plankton frolicked in the lakes, and greenery grew far and wide. The wetter conditions made it possible for “widespread human occupation and the development of agriculture across North Africa”. Amazingly, that last quote comes from Kuper and Kropelin fully seventeen years ago. Strangely the UN experts don’t mention very often that in the warmer world not that long ago, the hyperarid Sahara desert was rich, green and filled with water? We wouldn’t want people to start wondering if climate change might mean Chad and Libya could be nicer places for Africans to live? Instead we’re told that global warming will turn into our whole world into the Saharan desert, only to find out that in a warmer world […]

Jo Nova talks to Mark Steyn about Volcanoes and free speech

Watch on SteynOnline or ADH TV

By Jo Nova

My appearance with the wonderful Mark Steyn Tuesday is playing at SteynOnline, or on the Australian ADH TV.

Mark was tickled with the idea from my article last week: The science is settled but we just found 19,000 new volcanoes. He also wanted to talk about The crime of talking to Tucker Carlson and the Red-pilling of Naomi Wolf. We discussed other major science surprises like the mass phytoplankton blooms that seed clouds. That was another rule breaking surprise just two months ago — that moment when researchers realized that all the toluene and benzene pollution over the Southern Ocean was actually not caused by humans at all, but by phytoplankton.

We discussed the odd coincidence of how all the places that are warming in Antarctica seem to lie over the top of a 91 volcanoes we only discovered a few years ago. As I said, we know the surface of the moon better than we know the depths of the ocean. Only three men have visited the Mariana Trench and it’s only 11 kilometers from the surface of Earth, but 12 men have walked on the moon.

Where do people live?

These marvelous spike maps mark out a 3D representation of the population density on each two-kilometer-square pixel of Earth’s surface. There are no outlines for countries, yet for the most part we can still see where the land meets the sea.

Was the 2nd heaviest day of rain in Australia caused by a volcano in Chile?

Photo of the 2015 explosion of Calbuco Volcano in Chile, by Keraunos ob, posted on the Earth of Fire blog by Bernard Duyck.

 

By Jo Nova

A year ago I wrote about the odd link between the Hunga Tonga volcanic dust and floods in Australia, but perhaps volcanic dust also played a role in the savage rain bombs of 1893 that caused the infamous floods of Brisbane?

After Hunga Tonga erupted last year, about a week later unusually heavy rain started falling over Australia — even washing out the Indian Pacific Railway line connecting East and West Australia. A month later and the dust had gone around the world and returned to give us glorious sunsets followed by more rain bombs.

So it may be just a coincidence, but the second heaviest Australian rain bomb was on Feb 3, 1893. And three weeks earlier on January 7th the Calbuco Volcano in Chile had its largest eruption in the last 130 years?

In 1893 an astonishing, flabbergasting day occurred, where 907mm of rain dropped from the sky on Crohamhurst in Queensland (that’s nearly 36 inches!). It came in an astonishing week, where the heavens dumped 2 meters […]

Did volcanic dust from Hunga Tonga cause flooding in Australia?

Hunga Tonga-Hunga Ha’apai

By Jo Nova

Unusual rain in Australia started within days of the Hunga Tonga dust cloud travelling across the continent

On January 15th, Hunga Tonga launched a magma-powered thunderstorm that sent atmospheric shockwaves around the world. Ash, salt and particulates were carried through rising columns, right through the stratosphere, into the mesosphere and all the way up to 58 kilometers above Earth. For hours 400,000-odd lighting bolts zapped the airborne chemical soup.

The dust from Hunga-Tonga travelled West and reached Australia on Jan 18 – 20th. On Jan 21-22 flooding rain washed out the main railway line and roads in central Australia. Over the next few weeks, rains soaked the ground across parts of Queensland and New South Wales. By February 15th, the remnant volcanic dust that had circled the Earth and was back again creating rich red sunsets over Australia. A week or so after that, the rain bombs fell on South East Queensland, and travelled south through New South Wales to Sydney.

The big unknown is that the Hunga-Tonga volcano launched water vapor, salt and dust incredibly high — almost too high. The aerosols are far above the troposphere where rainfall originates and […]

The Tongan eruption sent shockwaves around the world

Scott Manley has done an excellent summary video of the Tongan volcano, much of the science and history of it as well as the effects thousands of miles away. The area around the volcano had completely reformed in the last ten years. He has collected some great footage together.

It’s interesting watching air pressure waves travel across Japan and the USA. Ken Stewart found the compression- decompression wave hit the east coast of Australia at about 5:16 Qld time and took 3 hours and 24 minutes roughly to get to Shark Bay, an average speed of about 1,160 kph. The decompression was about half an hour after the first peak and can be seen (still) in weather station pressure data.

Eruptions of Hunga Tonga-Hunga Ha’apai are roughly 900 years apart and this one was on schedule.

Thanks to Greg …

Did a short sharp Geomagnetic storm contribute to the Callide Coal plant explosion?

Ben Davidson speaks from Spaceweathernews.com and claims that there was a short sharp geomagnetic storm over the East Coast of Australia around the time the Queensland Callide Power plant exploded.

The CME that flew past Earth didn’t do much around the world, causing a small 1% deviation in magnetometers. But there was a burst of activity in the Southern Hemisphere that appears to have hit the east coast of Australia. Magnetometers there saw a 300 – 500% change* between noon and 3pm on the same day as the Callide Coal Power Plant blew up. The explosion happened at 1.44pm and the 275 kV transmission lines tripped at 2:06pm.

*(UPDATE: There is some contention in comments about the Australian DST figures — we’re they really that high or unusual? I’ll update the post when I can confirm it either way).

We don’t know if this tipped something over the edge at Callide, but the timing is highly coincidental. If Earth’s magnetic field is weakening it would seem urgent, to say the least, to understand the risks these spaceweather events pose to our critical infrastructure.

Perhaps an engineer who knows the design of (hydrogen cooled) supercritical coal reactors might be able […]

Surprise: The Last Ice Age was colder than anyone thought. Blame CO2!

We panic about the next half degree of warming (above the 1.5 we’ve already had) but the depth of the ice age was savagely cold. For years the experts told us what Earth’s temperature was then, but apparently they were wrong.

And yet corals and rainforest survived. Plus turtles, whales, kittens — lots of things. And all without research grants.

Nice line on the Nobel gas calibration with ground temperatures. Nice proxy.

Two studies have come out in the last 10 months both showing that at its coldest point about 25,000 years ago, the Earth was on average six degrees cooler Celcius than it is today. And this new study includes estimates of temperatures of tropical land near the oceans which ought to be more stable and less prone to big extremes.

This comes from a newer style of proxy based on noble gases dissolved in ground water. It appears to be quite an accurate proxy, judging by the graph to the right. And it solves a lot of problems with other proxies. We can take samples from all around the world instead of just the polar ice caps (like we can with ice cores). […]

Extinction level event? 42,000 years ago Earths magnetic field shrank to nothing

Don’t look now, it’s a climate disaster of massive proportions and it has nothing to do with CO2.

Scientists have just discovered what they say was a wild era 42,000 years ago — where the Earth’s magnetic field practically disappeared. They’ve called it the Adams Event (after Douglas Adams of Hitchhikers Guide fame).

This was hidden previously, just before the Laschamp Excursion which we’ve known about since 1969. That event happened about 41,000 years ago – during which the Earth’s magnetic field briefly flipped. It was a pretty big deal in itself. For 800 years the field strength fell to 28% of it’s current strength and was reversed North-to-south. Due to the weak magnetic field, the theory is that cosmic rays zinged further into the atmosphere and created a layer of enriched beryllium 10 and carbon 14 which remains to this day in a thin slice around the world buried under all the layers of dirt that came after it.

Around the world seismic measurements were quieter during lockdown

Something that marks how strange times are, was that in March and April, a group of seismologists found seismic activity fell by 50% at 185 stations around the world (at least in certain high frequency bands from 4 – 14 Hz). For example the three graphs below show seismic activity in Brussels, Barbados and New Zealand. A slight downturn happens at Christmas but the lockdown period fell far below that.

For the first time seismologists could identify small quake signals they had missed before.

Co-author Dr Stephen Hicks, from Imperial’s Department of Earth Science and Engineering, said: “This quiet period is likely the longest and largest dampening of human-caused seismic noise since we started monitoring the Earth in detail using vast monitoring networks of seismometers.

Who knows what they might figure out now they have a handle on human background “noise”.

Stop the press: Solar panels could stop Earthquakes

Experts predict a warmer world will be “geologically turbulent”. Join the dots, get a solar panel, and stop the world cracking up ok?

Below one national news outlet speculates about the effects storms, melting ice and floods have on crustal plates, and fault lines. It’s possible, unknown, or at least not-entirely-ruled-out that man-made CO2 could maybe theoretically lead to earthquakes, volcanic eruptions and tsunamis. The story contains stacked “ifs”, “buts”, “coulds” and caveats, plus some links that are not-statistically-significant and several “unknowns”.

This is essentially one-sided scientific rumour mongering. Quick let’s transform our economy.

This is what our future looks like if climate change goes unchecked

… experts predict a warmer and more geologically turbulent future for the planet.

The US Geological Survey has discovered there is one link between weather and earthquake.

Just one link?

Major storms, such as cyclones and hurricanes, can produce substantial changes in atmospheric pressure. This sometimes triggers a ‘slow earthquake’ – a slow but steady movement that does not create any noticeable jolt.

“They note that while such large low-pressure changes could potentially be a contributor to […]

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.

Glaciers on the move: Two minutes of extreme climate change on Swiss Alps, Italian beaches

The next ice coming to Europe might look something like the last ice age shown in this simulation. A time when Venice will be top of a long paddock that stretches to Albania.

In school children are taught to hyperventilate about the last 30m retreat of glaciers that never stayed put ever.

Instead, they could be studying this… (click to start)

At the 24,000 year BC point glaciers have wiped out Zurich, Bern, Geneva.

Now that was “climate change” 8200 years ago — California lashed by 150 years of storms

Don’t tell me that cold is nice and the climate was ever ideal

A few scientists thought that the climate was stable and well behaved during the Holocene until we invented coal power and the Ford Model T and everything fell apart “unprecedentedly”.

But 8200 years ago things apparently got pretty wild. See the GISP graph below where there was a three degree fall in temperatures suddenly (circled in red below). A new study found that at the same time China and California also cooled. Strangely, this cooling effect probably did not produce calm, happy days for the Californians at the time. Instead it looks like they got 150 years of intense winter storms and a lot of wet weather.

UPDATE: This graph shows the ice-core data up until 1855. The last 150 years (1705 to 1855) are highlighted in red to show the warming as the Earth began coming out of the LIA. Obviously that red line would continue up further if it was drawn to the present.

Looks like real climate change….

The reason for the sudden snap is possibly that a couple of massive glacial lakes in North East America collapsed and suddenly drained out […]

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 […]

Fossils show models can’t predict how climate affects animals

Fossils show those dang mammals lived in all the spots they weren’t supposed to live in. Climate models don’t predict the climate, and animal distribution models don’t predict (or in this case hindcast) animal distribution either. How little we know, and how adaptable is biology?

This calls into question all the headline prophecies about the extinction of cute furry critters due to climate change.

The modelers were sure that animals would be unable to cope with temperature changes and would not have lived in the same places as they do now during a climate so different. By crikey, it was an ice age! Yet those small mammals, whose defining biology is that regulate their own temperature, flummoxed the models by living nearer the glacier sheets where the models predicted they would not live.

All the alarming forecasts of local extinctions of mammals come from assumptions built into modern models that fail in multiple ways. The temperature changes from the last 20,000 years show that these mammals have already survived massive shifts, both colder and warmer, and that anything we face in the next century is but a flea on a hippo.

In the graph, the dots are the fossils, the […]

Climate science hopelessly politicized. Geological Society of Australia gives up on making any statement

So much for the consensus. In 2012 The Geological Society of Australia (GSA) was one of the few associations to make a slightly skeptical position on climate. For poking their heads above the parapet they’ve had years of headache and debate, and finally have issued a statement saying they have given up entirely on putting out any statement. The debate is so furious and divisive that no position could be agreed on. (I wonder exactly how many of their members are fans of climate models? Was this the work of just a few zealous believers?) I think I’ve hardly ever met a geologist who wasn’t somewhat skeptical.

The back story is that, like most science associations, in 2009 the GSA chanted the litany. (Their 2009 statement is here). They wrote that governments should take strong action to reduce CO2 and that meant paying geologists more to do research and sit on plum advisory committees. How predictable…

2. That Earth Scientists with appropriate expertise […]

The Marcott Hockey-stick: smoothing the past and getting a spike from almost no data?

The message to the world is unequivocal:

“We are heading for somewhere that is far off from anything we have seen in the past 10,000 years – it’s through the roof. In my mind, we are heading for a different planet to the one that we have been used to,” said Jeremy Shakun of Harvard University, a co-author of the study.

Source: The-world-is-hottest-it-has-been-since-the-end-of-the-ice-age–and-the-temperatures-still-rising.

There are two factors in the new Marcott paper that are major red flags. For one, there is hardly any data in the modern end of the graph. Ponder how researchers can find 5,000 year old Foraminifera deposits, but not ones from 1940? Two: they’ve smoothed the heck out of longer periods. Marcott et al clearly say there is “…essentially no variability preserved at periods shorter than 300 years…” So if there were, say, occurrences of a warming rise exactly like the last century, this graph won’t show them.

Some of the data has a resolution as poor as “500 years” and the median is 120 years. If current temperatures were averaged over 120 years (that would be 1890 to now), the last alarming spike would blend right in with the other data. Where would the average […]
