In the National Park Service website, it talks about Glacier Bay and Alaska.

https://www.nps.gov/glba/learn/nature/climate-change.htm

Warming is more pronounced at higher latitudes. Over the past 50 years Alaska's annual average temperature has increased at more than twice the rate of the rest of the United States' average, and here in Southeast Alaska winters are 5 degrees warmer. Glacier Bay is expected to become warmer and drier over the next century. Widespread effects in Alaska include earlier spring snowmelt, reduced sea ice, shrinking glaciers, melting permafrost, bark beetle infestations, shoreline erosion, and more forest fires.

I just returned from a cruise of Glacier Bay. It was absolutely incredible, but at the same time it was sad. You can literally watch as the ice slides off the glacier, and into the bay.

You should be able to do that at the front of any active glacier that terminates into the sea.

Given it has got a bit warmer it is likely that the galcier is in retreat. A bit.

If the glacier retreats out of the water it will require a lot of a temperature rise to get it to retreat further as the effect of the water it terminates in is to allow a very fast and effective transfer of heat energy from sunshine into the ice.

What is sad about this?

Yes, that reduction of ice albedo from soot causes excessive warming.

One is able to watch the ice slide off into the bay? That reminds me of a heavy BMW sedan my father once had. When you whipped over the autobahn at 190 Km you could watch the gas gauge sink.

And so, some tell us, we were pushing the ice into the bay and building a new habitat for bark beetles. That has a sentimental feel of Ancient Greek tragedies. Why, it is their very essence in a way.

In those days a Porsche street car made maybe 210 Kmh with a tailwind and Ferrari made barely 260 Kmh. In the meantime I admit to 300 Kmh a few times but mostly the Autobahn is too full for much over 250 and over long stretches it high speeds are forbidden or discouraged by intermittent restrictions. :(

"A bit" ????

Glacier Retreat in Alaska

About 5% of Alaska is covered by ice, in over 100,000 individual glaciers, many of which are unnamed. 98% of these glaciers are shrinking, with those at lower elevations experiencing the most rapid melting. Alaskan glaciers show some of the fastest loss in the world per unit area. From the mid 1950s to the mid 1990s, 12.5 cubic miles of ice was lost each year. This rate nearly doubled from the mid-1990s to 2001, to 23 cubic miles per year. This is nearly double the total loss from the much larger Greenland ice sheet during that time.

Really? 186 MPH?

That gets increasing hard to go that fast. It requires almost twice as much power as my car had.

What was it?

Wow..

98%...

Someone cataloged and followed over 98,000 glaciers...

Really...

Wow...

Sounds like someone is stretching the facts a bot...

Aye, and somewhat difficult to believe. 23 cubic miles is 100 km[SUP]3[/SUP]. Supposedly half or less the Greenland figure but still somewhat impossible.

10 years of that and there would be no ice in Alaska at all.

Thanks for pointing out yet another feedback that makes the warming that we are experiencing from CO2 even worse in terms of consequences.


I'm sure you didn't mean to, but both you and Watts dont really grasp the concepts too well.

It's data. Unlike you, I welcome it no matter where it leads.

You realize there is such a thing as satellites?

Observing glacier change from space
Click to expand...

Yes, but how well are satellites at detecting the density of the snowpack? You know, over time, several things of chemistry occur. Gravity shrinks the snowpack, and the deeper it is, it becomes solid ice because of the weigh. This rate is not going to be consistent, and affects several meter of the snow and ice. Without actual on site sampling, using satellites is rather inaccurate for the levels claimed by the pundits.

I'm sure if you find a paper on this topic, they will list the uncertainties.

Activist pundits almost always misrepresent the scientific facts.

Well, if it was German spec, someone removed the ignition cutoff. At least most cars made and sold in Germany are limited by the manufacturer to 250 kph. (155 mph). Things may have changed since I left in 1992 though.

I lived there for six years.

I used to regularly pass them and they didn't was a Firebird passing them!

And he knows, because he watched a you tube video.

Of course, if you actually look at the NASA website, they dont even try to claim glacial retreat is due to soot on ice. They are quite clear that its an effect of global warming caused by anthropogenic greenhouse gases.

But why bother with truth when you can spew lies over and over?

Would phys dot org be better for you?

https://phys.org/news/2016-03-unaccounted-arctic-microbes-glacier.html

If you wish to believe Watts is uninformed, the so be it. To dismiss such things just due to the source is a logical fallacy, and you are a denier of science with such a knee-jerk reaction. Afterall, if it isn't a topic listed in your Bible, the IPCC's FAR to AR5, then we deny it. Right?

There are several papers available on the topic, about how microbes, algae, dust, carbon, etc. changes the glacier albedo.

Here is a recent one:

Here is one a couple years old:

Porsche actually does not have a cut off in Germany. The cut off is self imposed and Porsche decided against it for marketing and sales reasons. The Corvette is or at least was without such a mechanism, when I drove it and did about the same speed as the Porsche. You could leave an M6 BMW in your tracks on the autobahn in acceleration and surprisingly its road ability was very much like the Porsche. It was quicker in autobahn curves than the BMW.

What do you do when some "white haired old bastard" like me pulls out in front of you because I forgot how to adjust my mirrors? ;)
