Greenland Temperature Updates

From NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Every year the Danish Meteorological Institute (DMI), whose remit covers Greenland, used to publish a full set of annual temperature graphs for all of the long running sites in that country.

These graphs consistently the same story- that temperatures between the 1920s and 50s were at a similar level to present ones.

For some reason, DMI stopped publishing these annual reports four years ago.

However the data is still available from GISS, so I am once again able to update the graphs for two of the main locations – Nuuk on the west coast and Tasilaq on the east:

https://data.giss.nasa.gov/gistemp/station_data_v4_globe

It was a particularly mild year in 2010 at Nuuk, and Tasilaq also had a warm year in 2016. But since then temperatures have reverted to 1930s levels once more, putting the lie to the Greenland meltdown scam.

The cyclical pattern of temperatures is intimately connected to the Atlantic Multidecadal Oscillation:

Oh dear.

In the end the data counts for very little, a bit of handy window dressing that sounds authoritative and mostly scary. For my money, Willie Soon explains it best…

Story tip: Report Finds UK Would Be £220 Billion Better off Without Net Zero Policies

Energy consultant Kathryn Porter last night released her report into UK energy policy for consultancy Watt-Logic: The True Affordability of Net Zero.

Relax Strat, our dear leader Starer has this under control. He has just signed a ‘reset’ deal with the EU such that the UK gives the EU all of the fish living in UK waters, actually to be fair it’s 75% but as the UK shore fishermen with line and rods account for the 25% we are allowed to hold onto. It is as good as 100% of all trawler/ factory ship catch taken from UK waters now goes to EU countries free of UK control.
The high cost of energy is also part of the deal. The UK will align with the EU carbon tax policy which means the UK will uplift its carbon tax by 100%. That will ensure the cost of UK energy continues to be the most expensive available and continues the control the EU had and has, over UK domestic energy policy.
Part of the deal gives the EU control of our energy options without the UK having any say whatever in the options?
Now that takes a genius to pull off that much damage in just a few months.
Oh, I almost forgot as well as handing our energy policy and our fish over to the EU we also handed our borders over too. Now it is possible to have unrestricted entry into the UK if you are under 30 years old.

I had several ‘Golden Nature Guides’ when I was a kid. I distinctly recall that in the descriptions of many of the critters, they would sometimes note which ones ‘tamed down quickly’ or ‘did well in captivity’ or ‘made good pets’, etc. Apparently, the citizens of many Western nations could be categorized similarly.

Europe might hope that something like what happened after Alexander The Great died, or The Anarchy, or Civil War Era in Norway.
That would divert attention for at least a couple of decades.

Yes four years is a long time in politics.
I am genuinely concerned the political class now believe they are above public opinion and beyond our control. I fear Starmer could already have a plan worked out to declare a national emergency in the spring of 2029 thus entitling him to scrap the election deadline.
Put nothing past this traitorous bunch now constantly destroying the fabric of the nation.

Whatever happened to Brexit?

After the Brits voted for their independence from the EU, why are they crawling back to the EU now?

The UK needs another Margaret Thatcher. Is Nigel Farage up to the job?

Some people make a rather good argument for Farage being the Establishment choice compared to more drastic ( read ‘extreme’) options.
One needs to take a look at the msm stories about Farage. That pushback seems diminishing.

The ice accumulation this season was below the average line until February when the wind patterns changed which opened up the snow storms. From what DMI publishes it looks like Greenland is about 50 GT of ice above normal and the forecasts indicate the snow will continue to the start of the melt season before tapering off. The melt season runs from early June to mid August and really is about where the summer highs and lows form.

A gigaton of ice is a billion metric tons or one cubic kilometer of ice. One good snow storm can deposit 8 GT over Greenland. One GT can fill 400,000 olympic swimming pools (for those that use this unit).

Layman often have difficulty with envisioning formal measurements. That’s why terms like ‘Olympic swimming pools’, ‘Hiroshimas’ and ‘homes’ are often used by the mainstream media.

The analogy “Hiroshimas” connotes instant catastrophic destruction with long term lingering toxicity.

Suits the alarmists’ objectives.

As a unit of energy: “the Earth receives approximately 87.2 billion Hiroshima bomb equivalents of energy from the Sun each year.”

If a gigaton (10^12 kg) of ice melts, the water would have a volume of a billion cubic meters. Since the area of the world’s oceans is about 360 million km2 (or 3.6*10^14 m2), a gigaton of extra water would raise sea levels by a whopping 2.8 microns (0.0028 mm), or about four wavelengths of red light. It would take 360 gigatons to raise sea levels by 1 mm.

The beaches of Florida (or Martha’s Vineyard, where Obama lives) are safe for decades to come.

Since 2000 Greenland has lost over 5,500 GT, about 250 GT/year.

Estimated, of course.

Yabut, don’t forget about Heidi Heat (remember her?. See, every second of every hour of every day, one hiroshima of heat plunges into the oceans, where we can’t see it, to reappear at some later time. It could even cause the oceans to boil. And the frogs hate that.

According to Anthropic it would take13.9 billion Hiroshima-sized nuclear explosions to melt the entire Greenland ice sheet.

Q: How many Hiroshimas would it take to melt the Greenland ice cap?

A: “This is an interesting physics problem that requires calculating energy requirements. Let me work through this step by step.
To determine how many Hiroshima-sized nuclear explosions would theoretically be needed to melt the Greenland ice sheet, I need to:

  1. Find the volume/mass of the Greenland ice sheet
  2. Calculate the energy required to melt this ice
  3. Compare this to the energy released by the Hiroshima bomb

The Greenland ice sheet contains approximately 2.85 million cubic kilometers of ice. Ice has a density of about 917 kg/m³.
Mass of Greenland ice sheet: 2.85 × 10^15 m³ × 917 kg/m³ = 2.61 × 10^18 kg
To melt ice, we need to:

  • Warm it to 0°C (if below freezing)
  • Supply the heat of fusion to convert ice to water

The heat of fusion for water is 334 kJ/kg.
Energy required to melt the ice sheet: 2.61 × 10^18 kg × 334 kJ/kg = 8.72 × 10^20 kJ
The Hiroshima bomb (Little Boy) released energy equivalent to about 15 kilotons of TNT. 1 kiloton TNT = 4.184 × 10^12 joules = 4.184 × 10^9 kJ
Energy from Hiroshima bomb: 15 kilotons × 4.184 × 10^9 kJ/kiloton = 6.276 × 10^10 kJ
Number of Hiroshima bombs needed: 8.72 × 10^20 kJ ÷ 6.276 × 10^10 kJ = 1.39 × 10^10
Therefore, it would theoretically take about 13.9 billion Hiroshima-sized nuclear explosions to release enough energy to melt the entire Greenland ice sheet, assuming perfect energy transfer (which wouldn’t happen in reality).
This is an enormous number that illustrates the massive scale of the Greenland ice sheet. It’s worth noting that this is a theoretical calculation – in reality, the energy from nuclear explosions wouldn’t be efficiently transferred to melting ice, and there would be many complex environmental effects that this simple calculation doesn’t account for.

Assumes an “all at once” event. If done in February, then radioactive snow and refreeze would ruin the math. This is the type of question that spirals into graphs and models with named scenarios…
But thanks fot the idea

Also: “This is an enormous number that illustrates the massive scale of the Greenland ice sheet.” or the reverse – illustrates the relatively small energy of a Hiroshima explosion (assuming you don’t live in Greenland during the experiment). I’d scale by “Tsar Bombas” or get away from bomb analogies all together. How many years of fueling every Starbucks espresso maker at once? That would probably be another big number, the art would be finding something that needs less than a million.

…..oh and don’t expect any weather improvements in your lifetime even if we get to 1.5 deg as that’s the way the climate and net-zero works-
Coastlines in danger even if climate target met, scientists warn

But even keeping to 1.5C would still lead to continued melting of Greenland and Antarctica, as temperature changes can take centuries to have their full impact on such large masses of ice, the researchers say.
“Our key message is that limiting warming to 1.5C would be a major achievement – it should absolutely be our target – but in no sense will it slow or stop sea-level rise and melting ice sheets,”
