Watch out for falling Walruses

David Attenborough thinks fossil fuels cause scores of walruses to careen off cliffs. The ABC is crying as it advertises the latest Netflix tear-jerker and WWF fundraiser.

In behind-the-scenes footage posted to YouTube by Netflix, producer and director Sophie Lanfear explained the events with tears in her eyes.

“It’s the sad reality of climate change,” she said.

“They’d be on the ice if they could be, but there’s no option but to come to land.

Actually though, it’s the sad reality of predatory polar bears

Canadian zoologist Dr Susan Crockford is all over it calling it Walrus Tragedy Porn. Apparently, the Attenborough footage is from 19 October 2017 in Ryrkaypiy, Siberia which was overrun with polar bears that terrorised the walruses. Five thousand walruses were herded to a cliff. Hundreds were driven over the edge to their deaths, and afterwards the polar bears feasted off McWalrus on the rocks. Apparently, it’s happened before and has nothing to do with sea ice: “We have records of walrus haulouts that are nearly a century old, including some from this part of the Arctic. The idea that walruses are being driven on shore by sea-ice […]

Climate change causes three meters of snow in two days, avalanches in Europe

It’s not well known, but in the same way that climate change causes every hot weekend it also causes snow dumps, avalanches, and freak weather. The scientific link is just as strong and calculated the same way. Take a tendentious cross-correlation on free-range seasonal assumptions, and then pour Vodka in the Cray.

If only the Germans had built more windmills they could have stopped this. Chaos in ski resorts, people trapped, road closed, flights canceled

Three metres of snow fell in the space of 48 hours in some parts of the country and more than a metre is forecast to fall today and tomorrow. — The Times (paywalled)

Heavy snow paralysed much of Europe for yet another day, cutting off mountain villages, sparking avalanches like one that crashed into a Swiss hotel, and killing at least four people.

At least 21 weather-related deaths have been reported in Europe in the last 10 days.

—ABC

With three million dollars to spend today (like every day) the ABC found cute photos of white stuff on cuddly sheep and scooters to fit the deadly theme. Nice.

There is avalanche danger, blocked roads and floods in […]

A close look at the arctic sea ice models that have launched the careers of a thousand polar bears

This is Expertise the UN can bank on

In the GWPF 2018 Lecture, Richard Lindzen pointed out the genius of Arctic climate models

First, for something to be evidence, it must have been unambiguously predicted. (This is a necessary, but far from sufficient condition.) Figure 1 shows the IPCC model forecasts for the summer minimum in Arctic sea ice in the year 2100 relative to the period 1980–2000. As you can see, there is a model for any outcome.

It is a little like the formula for being an expert marksman: shoot first and declare whatever you hit to be the target.

This will definitely happen according to the worlds top scientists at NASA, CSIRO, Geophysical Fluid Dynamics Lab (NOAA), National Centre for Atmospheric Research, The Hadley Meteorological Centre, the Max Planck Institute for Meteorology – Germany, the Institute of Numerical Mathematics of the Russian Academy of Sciences, the University of Tokyo, JAMSTEC (Japan), the Climate Research Division of Environment Canada, The Bjerknes Centre for Climate Research in Norway, the Institut Pierre Simon Laplace (IPSL), plus experts from Centro […]

Study shows we can save the Arctic with ship pollution?

Ships leave a trail of sulfur dioxide in the sky behind them which seeds clouds and causes cooling. At the same time, black soot drops out on the arctic ice, absorbs sunlight and causes warming. So which effect is bigger? Scott Stephenson et al tried to figure out that out and the cooling effect won.

The researchers also factored in global anthropogenic (human-caused) greenhouse gas concentration trajectories, adopted by the International Panel on Climate Change (IPCC), at a level closely aligning with today’s trends, along with global economic output that will drive the transport of goods.

“We attempted to fully integrate the interactions between the various components of the climate system in ways that have not been done before,” Stephenson says.

The main result was that the cooling effect won out over the warming effect in the simulations, to the tune of about one degree Celsius.

Zowie. One real degree of Arctic cooling sounds like rather a lot — even undoing greenhouse gas warming as well as soot based warming.

The cooling effect stops if we clean the smoke stack and remove […]

Climate change means Greenland is the same temperature now as 1880

Hands up who knew that Greenland has been pretty much the same temperature for the last hundred and forty years?

We know that there has been massive melting ice, shrinking ice sheets, a dark zone that is a huge problem, that the melting is accelerating, faster than at any time in the last 400 years. We all know “this is scary”, and due to climate change and could raise sea levels by 20 feet. And that’s just the news stories in the last two weeks.

At NoTricksZone, Kenneth Richards has found an up to date graph of Greenland temperatures buried in the supplement of a new paper by Mikkelsen et al., 2018:

….

So Greenland hasn’t been showing signs of warming since man made CO2 started rapidly rising after World War II. Indeed Greenland has been not responding to CO2 for 140 years or maybe a million.

Serious researchers have known this for years. It’s not like a flat trend suddenly popped up to surprise us.

Hat tip to Bob FJ for sending graphs and links of earlier studies last year. Even far back in 2004, it was obvious Greenland was not warming like it was supposed to. That […]

Big-gov-brain wants “half a trillion” to add ice to the Arctic

Sometimes an idea comes along that adds another chapter to the Book of Stupid. You might think windmills on land are an indulgent, pointless fantasy, but take that idea and make it worse:

(CNN) A team of scientists has a surprisingly simple solution to saving the Arctic: We need to make more ice.

A team at Arizona State University has proposed building 10 million wind-powered pumps to draw up water and spill it out onto the surface of the ice, where it will freeze faster. Doing so would be complicated and expensive — it’s estimated to cost a cool $500 billion, and right now the proposal is only theoretical.

It’s not like we have anything better to do with half a trillion dollars. Should we cure cancer or refrigerate one of the coldest places on Earth? Should we teach our kids about the fall of civilizations, or teach them to bow before prophets who keep predicting the end of the Arctic and getting it wrong?

Or we could add ice to the whole arctic for just $5 trillion

Tristan Hopper explains the beefed up plan would absorb the “entire steel production of the United States”, […]

Arctic Sea Ice — it all melted before and it didn’t matter

Matt Ridley in The Australian explains how every man and his dog is forecasting the doom of the Arctic sea ice, and not only have they been wrong year after year, but they all assume that if the ice all melts it’ll be a global disaster. But Earth’s already been-there done-that, and for years, and it was no-biggie. Polar bears obviously got through it, as did seals. Humans without protective solar panels somehow spread far and wide, and generally flourished.

I suspect the main climate refugees from the Arctic would have names like Donner and Blitzen. This is the one thing Matt doesn’t explain — in 8,000BC when the ice melted, what the heck happened with Santa?

Ice scares aren’t all they’re cracked up to be

This was a period known as the “early Holocene insolation maximum” (EHIM). Because the Earth’s axis was tilted away from the vertical more than today (known as obliquity), and because we were then closer to the Sun in July than in January (known as precession), the amount of the Sun’s energy hitting the far north in summer was much greater than today. This “great summer” effect was the chief reason the Earth […]

Hot magma is melting Greenland ice – can windfarms save it?

Here on the ball of magma called Earth, there’s a hot plume of rocks under Iceland that stretches right across under Greenland. Those hot rocks are melting the ice from below in a band 1,200 km long and 400 km wide.[1]

I don’t think solar panels are going to stop Greenland melting.

The main part of the plume has been progressing eastward over the last 120 million years, right under Greenland and now lies under Iceland.

Will the media take a million years to catch on?

Presumably, being world class journalists, from now on all ABC/BBC/CBC stories will not mention melting Greenland ice-sheets without also noting that geothermal heat may be causing it instead of your long hot showers.

But a similar study published in Nature Geoscience 3 years ago was the forerunner to this one with similar conclusions and the mainstream media don’t seem to have noticed yet.[2] No mention of magma, tectonics and hot rocks here: ABC — Antarctica’s melting ice alone could lift sea levels one metre by 2100, March 31st, 2016. Or here: ABC — Global warming melts last stable edge of Greenland’s Zachariae ice stream, March 17th, 2014. Or on the BBC – […]

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.
