So regional warming rather than Global Warming. Wink

No!


So you think no warming at all? Roll Eyes

Nothing. I posed a question. Wink

So far you haven't said anything one way or the other.

Im almost 30% positive your aware that you get localised climatic variation. I love you effort to try and obfuscate large chunks of ice melting. The ice is melting, Its getting hotter, the only scientifically credible explanation is AGW.

Oh absolutely. Natural Variation. But for it to be Global the effects must be GLOBAL.

Now you have jumped the shark. Gone from warming to AGW with no step in between. That is a belief system. The High Church of AGW.

You must understand that current global temperatures are a supposition. There are large areas of the globe with NO data. What they have to do is smear it to cover a greater area.

Then of course there is the claim that going back years to 1880, where the data is more sporadic, they can extrapolate how warm it was to two decimal places, including the oceans.

Sorry. But that is so unbelievable it is not funny.

You haven't even tried to look at normal warming. What did you expect coming out of the LIA? The IPCC claim that at least 50% of the warming since the latter half of the 20th century is manmade. They actually haven't produced anything to show it, it is merely an assertion.

Still no date of photograph on your pictures. That must be frustrating for you.

"In 1844, at the height of the Little Ice Age—a minor glacial advance recorded worldwide—the glacier was 8 km long, reaching all the way to where Icefield Centre is now. Now the glacier is nearly 2 km shorter."

Damn, the LIA was worldwide and it has lost about 2km in 170 years of recovery of temperatures.

Riddle me this. Why is the planet warming 10 times faster than at any point in the last 60 odd million years? whats your explanation for this anomaly?

Have you got a reference for that? A peer-reviewed paper?

...

Perhaps you prefer the Marcott reconstruction.

Marcott interview -

"Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the 20th-century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used. Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions."

http://www.realclimate.org/index.php/archives/2013/03/response-by-marcott-et-al/
"The Greenland records show that climate changes have been very large, rapid, and widespread. Coolings were achieved in a series of steep ramps or steps and warmings in single steps."

"In Antarctica the Byrd core from West Antarctica, and probably the Vostok and some other cores from East Antarctica, show events that are correlative to the larger millennial events of Greenland, including the Younger Dryas (6, 31). Byrd and Vostok also contain indications of events that may be correlative to nearly all of the Greenland events (31). "

Perhaps the most dramatic glacier withdrawal has been in the Alps, where it has occured in full view of residents, tourists and scientists. This is a 1859 etching of the Rhone glacier in the Kanton of Valais, Switzerland, when the ice filled the valley right to the tiny crossroads of Gletsch. In 2001 the glacier was nearly out of sight, 2.5 km distant and 450 M higher. (Ciceri etching courtesy Stefan Wagner, from Uber die Furka [1999, Limburg a/d/ Lahn, Germany].)


Perhaps urban climate could be a factor in why you see a recessive snowline at the same time of year, only 150 years apart. If the photograph is a tourist area today, perhaps having 10,000, 20,000, or 30,000 more people in the area would do something about the amount of snow in the region. The heating in houses would create a bubble of warmth in the region which keeps the snow away, or gradually keeps the snow melted a bit more than if no one lived in the region.

The town of Sion has grown from 3,000 in 1850, to 35,000 in 2016. Perhaps urban heat DOES have something to do with it.

Point #1 Glaciers are not "snow", thy don't have a "snow line". They are made of ice that doesn't melt from season to season. In fact that is how glaciers form. Snowfall that doesn't melt becomes ice. This ice becomes the glacier.

Point #2 What you are describing is the Urban Heat Island effect. This is where an urban area or metropolitan area is significantly warmer than its surrounding rural areas due to human activities.

The heat island effect is very local and the Rhone glacier won't be affected by this.

My point is that in Antartica, there are places where it has never ever gotten over 0 degrees. The ice in that region is called permafrost. It would takes years of tropic temperatures for this ice to melt.

Not so much for areas like Europe. Even in places of high altitude, snow and ice can melt in an unusually warm season of summer. And if you really want to say that it is a warmer recent climate that is causing the retreating glaciers, then you really are contradicting your point about glaciers not melting.

It looks like these are photographs of two different seasons in a single place. One of summer and one of winter. The purpose of these photos is nothing more than for propaganda in the "global waffle" chicken little's war.

The number of times I see Christmas footage of New York and the 4th of July footage of New York. It's either "global warming" or "not global warming". People are just too soft towards seasonal change.
