Sea birds struggling from loss of Arctic ice

[CrusaderFrank]

There are three main types of water masses in the Barents Sea: Warm, salty Atlantic water (temperature >3 °C, [37.4 °F] salinity >35) from the North Atlantic drift, cold Arctic water (temperature <0 °C, [32.0 °F] salinity <35) from the north, and warm, but not very salty coastal water (temperature >3 °C, [37.4 °F] salinity <34.7).

Note for Crusader Frank. Sea water will not freeze at 0 °C, [32.0 °F]​

Walrus, polar bears, harp, hooded and ring seals aren't the only species negatively impacted by the shrinking Arctic ice.

Seabird colonies are struggling as winter sea ice levels hover near record lows

Once again your link and YOUR approach to the perceived problem are misleading and dishonest, since YOU have been shown a number of published papers showing strong evidence of little (far less than now) to NO Summer ice and it lasted for long periods of time!

Yet all the animals you listed are still here, the world didn't crash and humans who at that time only had Flinstone cars in use for travel and LOW CO2 levels didn't cause that low sea ice to happen. Here are a few papers I have stored at another forum board:

“HISTORICAL REVIEW

Between 1000 and 1300 average summer temperatures were about 1°C higher than today, with the mean annual temperature higher by perhaps 4°C in a largely ice-free Arctic. Eric the Red, a renowned world citizen of that time, has been much maligned as the first progressive publicity man for giving Greenland a false image in order to attract settlers; but in truth, the southwest of that vast country was warmer and greener by far than at any time until the Fieldfares Turdus pilaris arrived there in the mid-1930s. The sea-temperature of the Atlantic was higher than it has been since, and there appears to have been none or very little ice to hinder the Vikings’ communications between Iceland, Greenland,Newfoundland and Labrador (Mowat 1965). Indeed Brooks (1926) considers thatthe polar ice-cap may have disappeared entirely during the summer months, tobuild anew each winter.”

New insights on Arctic Quaternary climate variability from palaeo-records and numerical modelling

December 2010

Martin Jackobsson, et al

Abstract

Terrestrial and marine geological archives in the Arctic contain information on environmental change through Quaternary interglacial–glacial cycles. The Arctic Palaeoclimate and its Extremes (APEX) scientific network aims to better understand the magnitude and frequency of past Arctic climate variability, with focus on the “extreme” versus the “normal” conditions of the climate system. One important motivation for studying the amplitude of past natural environmental changes in the Arctic is to better understand the role of this region in a global perspective and provide base-line conditions against which to explore potential future changes in Arctic climate under scenarios of global warming. In this review we identify several areas that are distinct to the present programme and highlight some recent advances presented in this special issue concerning Arctic palaeo-records and natural variability, including spatial and temporal variability of the Greenland Ice Sheet, Arctic Ocean sediment stratigraphy, past ice shelves and marginal marine ice sheets, and the Cenozoic history of Arctic Ocean sea ice in general and Holocene oscillations in sea ice concentrations in particular. The combined sea ice data suggest that the seasonal Arctic sea ice cover was strongly reduced during most of the early Holocene and there appear to have been periods of ice free summers in the central Arctic Ocean. This has important consequences for our understanding of the recent trend of declining sea ice, and calls for further research on causal links between Arctic climate and sea ice.

and this comment by Dr. Meier,

Watts Up With That?

NSIDC’s Dr. Walt Meier – part 2

“Can the Arctic really become sea ice-free during summer?

It has been suggested that the Arctic really can’t lose all its sea ice during summer because there isn’t enough energy to melt all of the ice in the short summer. There are a couple of reasons why this thinking is faulty.

First, we know the Arctic can potentially lose all its sea ice during summer because it has done so in the past. Examination of several proxy records (e.g., sediment cores) of sea ice indicate ice-free or near ice-free summer conditions for at least some time during the period of 15,000 to 5,000 years ago (Polyak et al., 2010) when Arctic temperatures were not much warmer than today.”

Melting point of ice is still 32F

And CrusaderFrank is still invincibly ignorant. That is the freezing point of water.

So where does water ice melt, -455F?

Can you give us a whole, non-imaginary number?

 

[cnm]

Gawds save us from the invincibly ignorant. I mean he didn't even understand, after begging for it, the explanation of how sea ice can melt when air temperatures are below freezing.

 

[cnm]

Oh, just had a thought. In case the explanation was too complex, which I suspect may have been the case judging by the response, the answer is that the sea is warmer than the ice.

Hope that helps.

 

[Crick]

There is also the point that it is winter in the Arctic and sea ice is growing at the moment. When summer comes it will melt. Over the course of the year, it will melt more than it will freeze. I would not pay much attention to Crusader Frank, JC456 or Skookerasbil. Their arguments are not worth the time.

"The Cooper Island colony wouldn't be there at all if it weren't for Divoky. Cooper Island is flat, unlike the tall cliffs and rocky slopes where Mandt's black guillemots usually nest. But while surveying the Island for the Smithsonian Institution in 1972, Divoky found a few guillemots nesting beneath crates and pieces of wood left by the U.S. Navy in the 1950s. He turned over some more pieces of debris to make new nesting cavities, and guillemots immediately moved into them."

Are you cricks sock puppet? You both have the same failed appeal to authority and no ability to cognitively think about the subject or ability to rationally explain your point, relying on others, to tell you what to say.

 

[Crick]

To what authority did CNM appeal? What was your post from "MISES, the journal of Austrian Economics, Freedom and Peace" if not an appeal to authority (though an extremely poor one).

Obviously the ocean below sea ice is above freezing. If the ocean warms, less sea ice will result. Warmer ocean water upwelling along the continental margins has been blamed for the destabilization and disintegration of several large Antarctic ice shelves. Perhaps your expertise falls off as one crosses the air/water boundary.

 

[boedicca]

Downsize what?

PS: by expressing a concern for the "white race" you declare yourself a racist. But then, you probably already heard that.

Could you possibly be more ignorant?

 

[Crick]

Why would that be?

 

[CrusaderFrank]

There is also the point that it is winter in the Arctic and sea ice is growing at the moment. When summer comes it will melt. Over the course of the year, it will melt more than it will freeze. I would not pay much attention to Crusader Frank, JC456 or Skookerasbil. Their arguments are not worth the time.

Ice melts in summer

"This new learning amazes me!"

You finally gave up on the ice melting in Arctic winter narrative? Praise Allah!

 

[Crick]

Frank,

Show me where I stated that ice melted in the Arctic winter. When you can't, you can admit your error.

 

[SSDD]

Here is an interesting side note on Arctic ice....and more evidence that the people who are reporting on it just can't be trusted...

This chart is well known...it is from the 1990 IPCC report...it shows the extent of arctic ice back to 1970...the chart was produced by NOAA

I suppose it was time for a new graph going back to the 1970's so here is the new one

They completely disregarded the known ice extent from the 70's and just made up new data to give the appearance of a constant loss of ice rather than the cyclical gain and loss that observation has shown us...These people simply are not to be trusted..they will make up fake data at the drop of a hat if they believe it will support the narrative and keep the funding rolling in.

 

[skookerasbil]

It's called debate.

No, it's called invincible ignorance.

Indeed.....but like everything in life, it only matters who rides off into the sunset a winner....



You'll maybe get it someday with age s0n.....those who stand in front of symbols and banners taking selfies are the losers of the world.

When America, China and India shut all their coal plants, come talk to me about invincible ignorance!!!

[jc456]

Frank, the Earth has seasons. And if you think NASA has been producing false images of the Arctic ice and PIOMAS false data on its volume, just say so.

And this thread is about sea birds. Do try to stay on topic.

you mean climate change?

 

[SSDD]

Walrus, polar bears, harp, hooded and ring seals aren't the only species negatively impacted by the shrinking Arctic ice.

Seabird colonies are struggling as winter sea ice levels hover near record lows

How do you suppose those sea birds got through most of the past 10,000 years? Do you ever actually think? Have you ever actually checked one of these nutty "nature in crisis" stories against what nature has done in the past? Or are you nothing more than a repository and mouthpiece for someone else's opinion? They say "here skidmark, go say this" and off you go...

By using the far greater span of time they were given by natural processes, to adapt.
