By the way did you like your first "up close look" at Donnie?

Would love to hear what "the take" is on Donnie?  Not just because I can't stand the person....but I am curious to hear what Europe's true take on Donnie is.

Greenland and Arctic Circle / Re: What's new in Greenland?

The following information is from a geologic map of Greenland, with my leading comments:
It appears the youngest igneous rocks in Greenland are on the order of 50 million years old.  I wouldn't expect the removal of all Greenlandic ice to re-energize significant (or actually any) volcanic activity. From here: "Extinct: It takes a lot to be an “extinct” volcano. The rule of thumb I use is about 1 million years since the last eruption … "

Science / Re: Trump Administration Assaults on Science

Trump is basically blinding NASA about climate change. This will be remembered as treason against mankind.

Trump's 2018 Budget Request Axes 5 NASA Earth-Science Missions

The other four Earth-science projects to get the ax in the proposed 2018 budget are the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite; the Orbiting Carbon Observatory-3 (OCO-3) experiment; the Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder; and the Earth-viewing instruments aboard the Deep Space Climate Observatory (DSCOVR) spacecraft.

He's following in Harper's footsteps, and it was this path that lead to Harper's crushing defeat.

We're hyper aware of denier screeds and may not realize how many potential voters care deeply about environmental issues. The loud, sometimes sponsored voices screaming out against AGW can make it seem a though they are the voice of the majority, but, no matter how many soc puppets one person manipulates, he still controls only one vote.
This budget will force every congress critter to put their name for or against the environment, then face their own constituents.
Bad for the environment, bad for Trump & bad for almost all Republicans. Should make the 2018 election interesting.


extremely accurate statement, once upon a time when everyone was afraid from an attack by the USSR of some kind i always said that i'm not afraid because not one government in history survived agains it's citizens and the prevailing public needs and opinion. hence you're spot on, it will only add to the downfall of those who try to protect their share of the cake now and as someone else said in this forum, it will be remembered as a crime "treason" agains mankind. bold words but not in a mood to repeat the lot to go into details, bad for everyone, exactly as you put it, thanks.

The demolition of the former ice bridge between Kjer Gletscher and the "New" free island Trekanten is continuing, the triangle shape of Trekanten remains:
Preliminary PIOMAS data shows a pretty weak melt in May so far (weakest in ten years by my estimatation from Wipneus' graphs).

While I still think there's a good chance of a record this year, I also think there's a good chance that 2012 overtakes 2017 mid June and never loses its lead again and that's enough for me to switch to 2018+2019.

once again i want to point out the melt rate will fall the less ice there is to melt. to avoid a lengthy post i use the same extreme example again, once there is no ice left the melt rate will be zero logically and since volume has been on earlier summer levels in april it is simply not possible that the same melt rate can happen, else we would reach zero in juli instead of miinimum during fall.
unfortunately i'm not good in explaining things short, it would fill pages time would i try, so i hope someone gets my point and perhaps puts it into better wording, something that thankfully happened in the past.

observers have to adapt their thinking patterns and expectations to new starting situations.
it's like if a ski race's start point is lowered a few hundred meters, that someone would call the race slow because the speed of the drivers is close the zero on the same spot while it was over 100km/h before when the start was higher up.

Dear Europe,

Apologies for having the Ugly American in Chief desecrate your soils this week.  Most Americans hang their head in shame daily at this abomination.
Arctic sea ice / Re: What the Buoys are telling

... which give me a rough estimate of the camera direction as 240 deg clockwise from north ...
So, WSW of the marker's pointer is Stefansson Island.

From Wikipedia:
Stefansson Island is an uninhabited island in the Canadian Arctic Archipelago in the Kitikmeot Region of Nunavut, Canada. It has a total area of 4,463 km2 (1,723 sq mi), making it the 128th largest island in the world, and Canada's 27th largest island. The island is located in Viscount Melville Sound, with M'Clintock Channel to the east. It lies just off Victoria Island's Storkerson Peninsula, separated by the Goldsmith Channel. Stefansson Island's highest mount is 267 m (876 ft).

The first European sighting of the island was in 1917 by Storker T. Storkerson who was travelling with Canadian explorer Vilhjalmur Stefansson (1879-1962), for whom the island was named.
(See interesting life of the explorer.)

VelliAlbertKallio, while the peaks in the picture have an overall shape that suggests they are younger than suggested elsewhere, the features that are visible are clearly all erosional, and none of the pyramidal shapes in view were erupted as cone shaped mountains  (ie, none of the features are from a partially eroded cascade-type stratovolcano).  As evidence, look at the stacked layers of lava that are visible - they were clearly emplaced as (apparently) continuous sheets on a nearly level landscape, and they remain nearly horizontal today.
As for the height of the mountains after so many millions of years of glaciation, I might be going out on a limb here, but I think that as the rock gets eroded away, the crust will rebound upwards in response to the removal of the top layers.

I would definitely be interested in whether there are any moribund volcanic sources in Greenland that may be reactivated by decompression melting, but the landscape in  the picture doesn't seem to be good evidence of anything recent
