I cannot openly subscribe to theory which at its underpinning are political activists who purposely fund and recruit scientific minds that agree with them.

Then you say that Arctic cloud feedback is negative. If global warming decreases cloudiness in the dark season allowing more radiation to escape from the surface, and increases in the bright season reflecting more solar radiation, it makes sense. But was this your argument?

Contrary to this, we often hear how less summer ice is triggering a death spiral due to the lower albedo of open sea compare to ice. I've found such arguments counter intuitive. I'm not sure if people making that argument have ever been in Arctic waters during the summer. It's foggy. Not always, but very often. Because the ocean is colder than the air above creating a slight inversion, I presume. And clouds and fog, if opaque, have a higher albedo than sea ice. So it's not entirely clear to me that open water should have this warming effect.

I think the effect needs to be measure from space, not from surface stations.

I wouldn't say the net effect is elusive exactly (certainly it was a decade ago, but not so much now).

What you describe here is a simple version of the description given in Wang & Key’s paper.

Where did you get these arguments from, if I may ask?

I worry if you are getting your information on climate science from questionable sources.

Arctic fog occurs first and foremost during summer. It is generally formed when mild, humid air moves over a colder surface, most often snow and ice, or a relatively cold ocean. The surface cools the lowermost air layers, which means that less water can remain in gaseous form. Some of it separates in the form of small drops, which float along with the air. Gradually they can become so numerous that visibility is radically reduced, and fog is a fact.

The depth of the typical Arctic fog is limited to often only a few tens of metres. Most affected are the ocean and coastal areas where mild air from the south comes into contact with ice or a cold sea surface. The stations on Bjørnøya and Hopen report fog in about 20% of all weather observations in July, whereas the frequency in January is only about 1%. These frequencies are probably somewhat greater than those over the surrounding sea, because the slight rise and consequent cooling of the air over the islands can be sufficient to release fog. This phenomenon is still more pronounced when the air is forced to move over mountains and glaciers. Huge cloud banks are then easily formed. In the mountains this is experienced as fog, and is often combined with drizzle or slight snowfall. On the lee side the air sinks again and the clouds dissolve. In the inner parts of fjords and valleys the fog frequqntly is usually low.

I believe CO2 is not measured on the dormant Mauna Kea volcano, but rather on the slope of the very active Mauna Loa volcano.

A bold statement. What makes this science so special that it's exempted from the test of time?

So for the feedback from global warming to be negative by this argument we must then be certain that global warming indeed reduces cloudiness in winter and increase it in summer. How are you sure that this is the case?

Fog forming over open sea in the Arctic in summer?

My worry is that nobody seems to mention it when discussing changing summer sea ice and albedo. … I would like to see it discussed somewhere.

Because I we they a lot of very smart people who specialize in this field checked.

Please take just a moment to reread the full paragraph you quoted from again to make sure you correctly understand the context.

Which journals did you review when researching this topic?

Good thing that you checked, then. Can you provide the data?

The Google journal.

What do your data tell you about cloud fraction, height, micro and macroscale cloud properties, or radiative flux between surface, cloud, and top of atmosphere?
