Has been for Billions of years and the Holocene isn't going to last forever. Glaciation isn't that far off.
Enjoy!
Enjoy!
Billions of years?
Yep, it gets very noticeable once you get past 70!
I see our illustrious bottle recycler has nothing but time on his hands today!
Come on!! How many places on earth have permafrost???

It is distressing that the average human cares so very little for it;s global home. If their personal home were treated in the same manner they would have to burn it down every second year.
Simply google Arctic beaches and you will find pictures of them with polar life evident.
A new model of the Sun’s solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun’s 11-year heartbeat. The model draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone. Predictions from the model suggest that solar activity will fall by 60 per cent during the 2030s to conditions last seen during the ‘mini ice age’ that began in 1645. Results will be presented today by Prof Valentina Zharkova at the National Astronomy Meeting in Llandudno.
It is 172 years since a scientist first spotted that the Sun’s activity varies over a cycle lasting around 10 to 12 years. But every cycle is a little different and none of the models of causes to date have fully explained fluctuations. Many solar physicists have put the cause of the solar cycle down to a dynamo caused by convecting fluid deep within the Sun. Now, Zharkova and her colleagues have found that adding a second dynamo, close to the surface, completes the picture with surprising accuracy.
“We found magnetic wave components appearing in pairs, originating in two different layers in the Sun’s interior. They both have a frequency of approximately 11 years, although this frequency is slightly different, and they are offset in time. Over the cycle, the waves fluctuate between the northern and southern hemispheres of the Sun. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97%,” said Zharkova.
Zharkova and her colleagues derived their model using a technique called ‘principal component analysis’ of the magnetic field observations from the Wilcox Solar Observatory in California. They examined three solar cycles-worth of magnetic field activity, covering the period from 1976-2008. In addition, they compared their predictions to average sunspot numbers, another strong marker of solar activity. All the predictions and observations were closely matched.
Looking ahead to the next solar cycles, the model predicts that the pair of waves become increasingly offset during Cycle 25, which peaks in 2022. During Cycle 26, which covers the decade from 2030-2040, the two waves will become exactly out of synch and this will cause a significant reduction in solar activity.
“In cycle 26, the two waves exactly mirror each other – peaking at the same time but in opposite hemispheres of the Sun. Their interaction will be disruptive, or they will nearly cancel each other. We predict that this will lead to the properties of a ‘Maunder minimum’,” said Zharkova. “Effectively, when the waves are approximately in phase, they can show strong interaction, or resonance, and we have strong solar activity. When they are out of phase, we have solar minimums. When there is full phase separation, we have the conditions last seen during the Maunder minimum, 370 years ago.”

Brrrrrr.

SO by your logic snow and ice must be caused by global cooling. Which it is doing in spades right now.
So how did that ice free Arctic ocean by 2013 thing work out for you?
And that's the way it is like it not we will enjoy many more weeks of snowmobiling every season till the peak in 2030, above 45 degrees nothing will grow but ice. A down aint it? I,m twenty-six degrees into the permanent miserable fukkin winter, I,m condemned to shoveling snow till I collapse on the front steps. They won't believe any of that Petros.
There is a bright side it could be a dry cold with little percipitation but I ain't that lucky. I think I've known that winter would kill me for a long time. I can't stop the rain.
Firewood and an teepee you can bank it with snow.
I don't mean anything the damn the minimum means everything. It's a good time to be danceing arround bonfires and praying to your gods.

You have to talk slower to me this evening, I missed everything you just said.
And the sunlight?

Optional.
That's slow lar plowered alright!
When I said almost pre carbide, I meant coming THIS way in time.
