Greenland Surface Temperatures Fall for 20 Years in Fresh Blow to Climate Alarm Narrative

by C. Morrison, Nov 27, 2024 in WUWT

Further evidence that surface temperatures across Greenland have been cooling for around 20 years has emerged with the recent publication of findings from a group of Thai scientists and mathematicians. Processing 31,464 satellite recording from 2000-2019 over the entire area, they found that the average temperature fell by 0.11°C. This is said to indicate a “non-significant change in LST [land surface temperature]”. The latest evidence of actual cooling over a significant area of the Arctic will not be news in scientific circles since it backs up previous findings of recent temperature falls. But the information is of course kept out of the mainstream since it casts doubt on the key Net Zero scare about soaring sea levels caused by the catastrophic melting of the Greenland ice sheet.

There are some crumbs of comfort for alarmists since the Thai authors found that the ice-free sub-regions of Greenland are warmer than the ice-covered sub regions. But perhaps not – the authors attributed it to “population density”. Urban heat yet again corrupting the temperature data, even in Greenland. The illustration below charts the temperature record for all areas of Greenland.

The World Economic Forum recently reported on a study that predicted a “total collapse” of the Greenland ice sheet within a few months. This suggestion is only slightly more ludicrous than the scares routinely published to induce mass psychosis in populations with the aim of promoting a collectivist command-and-control Net Zero solution. The recent farce around the COP in Baku showed the conspiracy operating in plain sight. Stop the developing word developing with hydrocarbons, then invent a number of fake scares such as island states disappearing beneath the waves. Everyone knows this and most of the other scares are false as scientists have shown on numerous occasions, but no matter. Invent some ridiculous composite figure – say $250 billion a year, or $1.3 billion by 2035 – then pretend your taxpayers can be rinsed even though the only country that could conceivably afford it is leaving the party in January.

Brown Bears Lived In The 73°N Siberian Arctic 3500 Years Ago…Today Their Northern Boundary Is 65°N

by K. Richard, Oct 14, 2024 in NoTricksZone

A new study provides still more evidence the Arctic was warmer than it is today as recently as a few thousand years ago.

In 2020 the well-preserved carcass of a Yakutian brown bear (Ursus arctos) was discovered buried in permafrost on the terrain of the treeless tundra Bolshoy Lyakhovsky Island in the Arctic Ocean, 73°N.

The Yakutian brown bear currently occupies only the forested regions of Eurasia, with a northern limit of northern Yakutia (Republic of Sakha), 65°N.

The female bear’s age has been dated to approximately 3500 years ago, during the Middle to Late Holocene. At that time the Arctic was warm enough at that latitude to support vegetation (grasses, shrubs) that only persist in the northern Yakutia region today.

The authors suggest brown bears may have been permanent residents of the Siberian Arctic’s islands from about 5000 years ago until a few thousand years ago, when, as today, the Arctic became too cold for the vegetation production requisite for their sustenance.

Now You Sea Ice, Now You Don’t

by W. Eschenbach, Apr 20, 2024 in WUWT

I got to thinking about sea ice and the climate models. Here’s what we know about polar sea ice extent, showing data that starts with the satellite era when we began to have accurate observations of the poles.

Figure 1. Arctic, Antarctic, and global sea ice extent. Colored lines are CEEMD smooths of the underlying datasets.

Now, there are some rather large curiosities regarding the sea ice extent records.

  • The North Pole is a liquid ocean covered with sea ice, with most of the ice polewards of 70°N. The South Pole is a giant chunk of frozen rock surrounded by sea ice, with almost no ice polewards of 70°S. So why do both poles have about the same extent of sea ice?
  • From the start of the satellite era up until ~2015, Arctic sea ice extent was decreasing and Antarctic sea ice extent was increasing … and as a result, total global sea ice extent was relatively constant, with 2014 having about the same global sea ice extent as 1978. Why?
  • Around 2015, Antarctic sea ice extent started dropping rapidly … but Arctic sea ice stopped dropping and leveled off up to the present. Why?
  • After dropping precipitously for a couple of years, Antarctic sea ice extent leveled off again … and as a result, global ice extent also leveled off. Why?

Here’s the interesting part. Nobody knows the answers to any of those questions. And I suppose predictably, since they’re based on our (mis)understandings of the climate, none of the climate models either forecasts or hindcasts sea ice extent doing anything even remotely similar to the actual observations.

So I’ll leave this here as a testament to just how little we understand the magnificent global heat engine that we call the climate …

Arctic “Just-So Stories”: Bad Science by Climate Alarmists

by J. Steele, Feb 14, 2024 in WUWT

The Arctic Ocean was nick-named the “upside down Ocean” by Fridtjof Nansen. Nansen was a famous Norwegian zoologists, oceanographer, and Arctic explorer as well as winner of the 1922 Nobel Peace Prize. During his failed expedition to reach the North Pole, his boat, the Fram, got frozen in Arctic sea ice but eventually was exported by Arctic currents, along with Arctic sea ice, into the Atlantic through what is now named the Fram Strait.

Nansen named the Arctic Ocean the “upside down ocean” because contrary to other oceans, the surface waters are the coldest, while between 100 and 900-meters depths the ocean is warmer due to inflows and storage of warm salty Atlantic waters. Sea ice cover prevents the ventilation of that stored heat. However, increases in open water allows more heat ventilation which has raised Arctic air temperatures 2 to 7 times faster than the global average. Open waters have been increasing due to changes in wind direction and currents. Open water is not proof of melting.

NASA estimates that globally added CO2 has increased downward infrared and added “a little over 0.8 Watts per square meter” of energy which their Just So stories claim melted sea ice. But researchers (e.g. Kim 2019) have reported that over open water more winter heat, about 2 Watts per meter squared, is being ventilated heat away more than absorbed. That suggests radiative cooling!

Another Tipping Point Cancelled—Claims Of Runaway Greenland Ice Melt Overblown

by  Klimanachrichten, Oct 23,2023 in ClimateChangeDispatch

We have carefully read the definition of a “tipping point” as conveyed by the Potsdam Institute (PIK):

“It’s like a pencil that you push further and further over the edge of a table with your finger. First nothing happens – then it falls.” That’s what the PIK website says.

Nothing can bring the pencil back to the table except a failure of gravity, which is not conceivable. [emphasis, links added]

Then PIK lists various “elements” that are supposed to exhibit such behavior. To the Greenland Ice Sheet (GrIS), one finds:

There are indications that the tipping point, which leads to an almost complete loss of ice in the long term (about 10,000 years), could probably be reached at a global warming of just under 1.5°C (possible from 0.8°C global warming, at the latest at 3°C).“

Now there’s a paper on the subject that has appeared in “Nature“, which paints a different picture. It finds that even after a possibly “critical warming threshold” has been crossed, “the pencil does not fall down”:

We find several stable intermediate ice-sheet configurations … that return to the present-day state if the climate returns to present-day conditions.”

In addition, models often determine the warming in Greenland (the root of the evil) using the mean global warming rate and then apply an “Arctic amplification” factor to each warming to determine the temperature swing in Greenland.

The paper states:

Recently, it has been shown that the Arctic warms four times faster than the global average and thus substantially exceeds previous estimates and projections from climate models.

Arctic amplification of this magnitude would reduce the safe space for the GrIS substantially. However, surface temperatures around Greenland might not increase that severely in the future.”

Observations since 2000 now show that during this period, the warming of the Arctic is far from uniform:

17 years of near-zero trend in September sea ice demolishes claim that more CO2 means less sea ice

by Polar Bear Science, Sep  23, 2023

If the hottest year ever can’t precipitate ‘ice-free’ conditions in September, what’s it going to take? Arctic sea ice failed to nose-dive again this year, undoubtedly disappointing expects who have been anticipating a ‘death-spiral’ decline for ages. Arctic sea ice hit its seasonal low sometime around mid-September this year and although the precise value hasn’t been published, the average September ice coverage will likely be about 4.2 mkm2 once it gets announced in early October.

This means we have now had 17 years of a near-zero trend for September sea ice, extending the nearly-flat trend NSIDC sea ice experts acknowledged four years ago. This surely busts a huge hole in the prevailing concept that more atmospheric CO2 causes less summer sea ice. Note that CO2 levels measured in August 2023 were 419.7 parts per million (ppm), compared to 382.2 in August 2007, a rise of 37.5ppm with no corresponding decline in summer sea ice (and vs. 314.2 ppm in 1960). Measured in metric tons, CO2 emissions due to fossil fuels rose from 31.1 billion in 2007 to 37.1 billion in 2021 (last year of data), again with no corresponding decline in summer sea ice.

Arctic 2023 Refuses To Melt…German Scientists Blame ‘Unusual Weather’

by P. Gosselin, Sep 17, 2023 in ClimateChangeDispatch

Sixteen Years Of No Decline

Arctic summer minimum sea ice extent refuses to drop further, surprising and frustrating the alarmist media.

German research vessel Polarstern of the Alfred Wegener Institute (AWI) is currently underway again in the Arctic where a decrease in sea ice had been expected there, or, probably more accurately said, hoped for. [emphasis, links added]

But this year the minimum Arctic sea ice extent has turned out differently, as Germany’s widely viewed (climate-alarmist) Tagesschau news had to report:

In view of the extreme summer, the question arose in advance: Will the Arctic also see a new negative record in melting ice this year? This time, the Arctic has been spared.

AWI director and expedition leader Antje Boetius tells Tagesschau that an unusual weather phenomenon prevented a record melt of Arctic sea ice this summer.

According to Boetius, a sequence of low-pressure systems has led to an entirely different ice movement. The so-called transpolar drift, which describes the drifting of ice along certain routes, took a different course this year, she said.

Ice from the Siberian region has been held together and compressed instead of drifting out and melting. For the AWI director, this shows that weather phenomena determine the development of sea ice, and that forecasting is more difficult than ever.

The Arctic, with its sea ice and life, has been lucky once again, says the biologist. But things could go the other way. “If we are unlucky, if weather phenomena play unfavorably, we can also be affected by large ice-free parts much sooner than expected,” Boetius adds.”

We notice that when the opposite happens, e.g. heat, storms, or more ice melt, then it’s all because of climate warming. But when it goes the other way, then it’s weather!

High sea surface temperature in North Atlantic

by Arctic News, Apr 22, 2023

SST World (60S-60N)

On April 20, 2023, sea surface temperatures (between 60°South and 60°North) had been at 21°C or higher for as many as 32 days. Such temperatures are unprecedented in the NOAA record that goes back to 1981.

 

On April 4, the sea surface temperature in 2023 (black line) was as much as 0.3°C higher than in 2022 (orange line) and we’re only just entering the upcoming El Niño.

 

SST North Atlantic

The situation is especially critical in the North Atlantic. Vast amounts of ocean heat in the North Atlantic are moving toward the Arctic, threatening to cause rapid melting of Arctic sea ice and thawing of permafrost. Last year, North Atlantic sea surface temperatures reached a record high of 24.9°C in early September and, as illustrated by the image below, the North Atlantic sea surface temperature on April 20 was as much as 0.5°C higher in 2023 (black) than in 2022 (orange).

As we’re moving into the upcoming El Niño, the Arctic Ocean can be expected to receive more and more heat over the next few years, i.e. more heat from direct sunlight, more heat from rivers, more heat from heatwaves and more ocean heat from the Atlantic Ocean and the Pacific Ocean.

Scientists Say A 6°C Warmer-Than-Today Arctic Is ‘Optimal’ For Thermophile Species

by K. Richard, Apr 6, 2023 in NoTricksZone

Back in the Early Holocene, when CO2 levels were said to be ~255 ppm, Arctic Svalbard was warm enough to accommodate abundant numbers of thermophiles, or warmth-demanding species. Only “remnants” of these species and their habitat exist in today’s much-colder Arctic.

With the exception of a few centuries in recent millennia, today’s Svalbard (Arctic) is the most glaciated it has been in the last 10,000 years (see the blue trend line in the below chart from Brožová et al., 2023).

…

 

This region is today about 6°C colder than it was during the early Holocene (~10,000 to 8,000 years ago), a climatic period scientists characterize as an optimum, or “most favorable,” for a “rich species pool” of thermophiles.

The sea surface temperatures (SSTs) in the western Barents Sea were as warm as 13°C and “sea ice-free during most of the mid-Holocene” (Łącka et al., 2019). In contrast, today’s SST in this region are as cold as they were during the last glacial (2-4°C), when CO2 hovered near 200 ppm. Rapid double-digit SST fluctuations, varying from 3 to 13°C, have been ongoing throughout the Holocene.

Why Is Antarctica’s Climate Considered ‘Global’ But Arctic Siberia’s Is Not?

by K. Richard, Jan 26, 2023 in NoTricksZone

Independent analyses from multiple independent sources indicate Arctic Siberia was 3 to 5°C warmer than today during the peak of the last glacial, or when CO2 levels were below 200 ppm.

Measurements from Antarctica’s ice sheet are almost invariably used to characterize both the global-scale atmospheric CO2 levels and climate for the last 10s to 100s of thousands of years.

But it is rather odd that Antarctica’s climate is considered globally representative (i.e., “global warming”) since there has been no warming here for the last seven decades.

Further, ice samples from Antarctica have CO2 values that range between 900 and 2900 ppm (Matsuo and Miyake, 1966) for the modern period (i.e., the 1960s). These values are far outside the range of the accepted modern global atmospheric values (~300 to 400 ppm).

On the Annual and Semi-Annual Components of Variations in Extent of Arctic and Antarctic Sea-Ice

by Lopes F, Courtillot, V. et al., 2023  in MDPIGeosciences

Abstract

In this paper, the 1978–2022 series of northern (NHSI) and southern (SHSI) hemisphere sea ice extent are submitted to singular spectral analysis (SSA). The trends are quasi-linear, decreasing for NHSI (by 58,300 km2/yr) and increasing for SHSI (by 15,400 km2/yr). The amplitude of annual variation in the Antarctic is double that in the Arctic. The semi-annual components are in quadrature. The first three oscillatory components of both NHSI and SHSI, at 1, 1/2, and 1/3 yr, account for more than 95% of the signal variance. The trends are respectively 21 (Antarctic) and 4 times (Arctic) less than the amplitudes of the annual components. We next analyze variations in pole position (PM for polar motion, coordinates m1, m2) and length of day (lod). Whereas the SSA of the lod is dominated by the same first three components as sea ice, the SSA of the PM contains only the 1-yr forced annual oscillation and the Chandler 1.2-yr component. The 1-yr component of NHSI is in phase with that of the lod and in phase opposition with m1, while the reverse holds for the 1-yr component of SHSI. The semi-annual component appears in the lod and not in m1. The annual and semi-annual components of NHSI and SHSI are much larger than the trends, leading us to hypothesize that a geophysical or astronomical forcing might be preferable to the generally accepted forcing factors. The lack of modulation of the largest (SHSI) forced component does suggest an alternate mechanism. In Laplace’s theory of gravitation, the torques exerted by the Moon, Sun, and planets play the leading role as the source of forcing (modulation), leading to changes in the inclination of the Earth’s rotation axis and transferring stresses to the Earth’s envelopes. Laplace assumes that all masses on and in the Earth are set in motion by astronomical forces; more than variations in eccentricity, it is variations in the inclination of the rotation axis that lead to the large annual components of melting and re-freezing of sea-ice.

Arctic Report: primary productivity still high & sea ice flatline continues despite warmer temperatures

by Polar Bear Science, Dec 14, 2022

Posted on December 14, 2022 | Comments Offon Arctic Report: primary productivity still high & sea ice flatline continues despite warmer temperatures

NOAAs annual Arctic Report Card is, for the most part, a valiant effort to turn good and ambiguous news into harbingers of climate change disaster. Primary productivity is up across most of the region (good news for wildlife) and despite Arctic temperatures being “twice as high” as the rest of the world in recent years, the summer sea ice ‘death spiral’ has failed to materialize.

Oddly, there is no bad news about polar bears (last mention was 2014). However, the media were told that the few hundred sea birds that died this year in the enormous Bering/Chukchi Sea region over the four months of summer in 2022 is a portend of climate change catastrophe–even though the authors of the NOAA report admit they have no conclusive evidence to explain the phenomenon. However, here are also some honest figures that are quite illuminating.

Sea ice

The graph at the bottom of this graphic, spread out rather than bunched up to make changes seem more dramatic, makes it much easier to see the lack of a declining trend in sea ice extent since 2007, and that winter (March) coverage has changed hardly at all.

September Arctic Sea Ice Trends

by P. Homewood, Oct 8, 2022 in NotaLotofPeopleKnowThat

We looked at the Arctic sea ice minimum for this year a couple of weeks ago. But the average for September as a whole is much more relevant.

In fact it shows very similar results this year, with average September extent slightly below last year, but otherwise the highest since 2014, and also much greater than in 2007:

https://ocean.dmi.dk/arctic/icecover_30y.uk.php

Note the grossly misleading trend line, loved by all Arctic alarmists! Their trend cannot conceal the fact that the ice extent stopped declining in 2007.

The ice could remain stable for the next century, but DMI’s overall trend line would still show a long term decline decline.

What Happened To The Ice-Free Arctic?

by P. Homewood, Sep 26, 202 in NotaLotofPeopleKnowThat

I wonder how these predictions worked out? (Answers tomorrow!!)

Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice.

Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years.

Professor Wieslaw Maslowski told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss.

Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times.

Remarkably, this stunning low point was not even incorporated into the model runs of Professor Maslowski and his team, which used data sets from 1979 to 2004 to constrain their future projections. “Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007,” the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC.

“So given that fact, you can argue that may be our projection of 2013 is already too conservative.”

Trend Change? Greenland Ice Mass Loss Has Been Decelerating Since 2012

by P. Gosselin, Sep 24, 2022 in NoTricksZone

We have digitized the Polar Portal’s graph of the accumulated surface mass balance and have come up with a value of 467 Gt. That’s 100 Gt or 27% above the 1981…2010 mean! Together with the melting of icebergs (assuming the value of the previous year, which was already 10% more than that of 2020 ) this results in approximately the representation below, which was included in the publication until the report 2020.

In 2021, one has probably omitted for reasons, perhaps the jump was difficult to explain by the calving of icebergs?

The total mass balance is very likely -100 Gt. An “accelerated” thawing of the Greenland ice sheet is not to be recognized. If one accumulates the mass loss, one sees the “braking” very nicely. Acceleration occurred until 2012.

The Climate Scaremongers: The Great Arctic Sea Ice Scam

by P. Homewood, Sep 23, 2022 in ClimateChangeDispatch

 

 

For years the ‘experts’ have been telling us that the Arctic would soon be ice-free in summer.

Al Gore notoriously warned us in 2009 that ‘there is a 75 percent chance that the entire north polar ice cap, during the summer months, could be completely ice-free within five to seven years.’

He was, of course, just a politician. But a whole host of supposed Arctic scientists were all busy issuing similar warnings at the time. [bold, links added]

In 2007, for instance, Professor Wieslaw Maslowski told us that northern polar waters could be ice-free in summers within just five to six years.

In December of that year, Jay Zwally of Nasa agreed, giving the ice till 2012. A year later, in 2008 Professor David Barber went one step further, saying the ice would all be gone that very summer.

For sheer persistence in getting it wrong, however, the prize must go to Peter Wadhams, professor and head of the Polar Ocean Physics Group in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge:

…

• In 2012, he predicted that the Arctic would be ice-free by 2015/16.

• In 2014, he thought it might last till 2020.

• In 2016, he confidently predicted the Arctic would be ice-free that summer (though curiously he now defined ‘ice-free’ as less than 1 million square kilometers).

All these pronouncements were designed for political propaganda purposes, not for scientific reasons, and were widely propagated by the gullible media.

Attenborough’s Arctic Sea-Ice Fearmongering Bordering On Misinformation

by C. Morrison, Sep 13, 2022 in ClimateChangeDispatch

The Arctic has been a happy hunting ground for the climate scaremonger Sir David Attenborough. Two years ago he made the fanciful claim that polar bears could die out in the 2030s.

It is now generally accepted that polar bears have been thriving and increasing in numbers, and in his latest BBC documentary Frozen Planet II, Attenborough makes no mention of his previous claim. [bold, links added]

But he does make the astonishing suggestion that all the summer sea ice in the Arctic could be gone within 12 years.

Unfortunately, such predictions are now out of date. Summer sea ice hit a low in 2012 and has been steadily recovering ever since.

According to the latest data from the US-based National Snow and Ice Data Center (NSIDC) for the end of August, “Sea ice extent is likely to remain higher than in recent years.”

The evidence is shown in the graph below.

….

As can be clearly seen, the 2022 blue line is well above the 2012 low point. According to the NSIDC, the average sea ice extent for August ranked 13th lowest in the recent satellite record.

The growth of Arctic sea ice has been confirmed by a number of sources. The EU weather service Copernicus reported that the coverage of Arctic sea ice is now very close to the 1991-2020 average.

Polar Opposite: Polar Bears Require Thin Ice Or Open Water To Survive

by K. Richard, Sept 5, 2022 in NoTricksZone

Abundant polar bear remains dating to 8000 to 9000 years ago have been found on Zhokhov Island, which is today surrounded by year-round sea ice (even in summer). This Arctic latitude (76°N) is too cold and thus too ice-covered for polar bears to inhabit today.

During the Early Holocene CO2 concentrations ranged between 255 to 265 ppm, and yet the Arctic was 5-7°C warmer than it is today and many regions that are now sea ice-covered were sea ice-free.

For example, Zhokhov Island is tundra and treeless today. It’s surrounded by permanent sea ice, making it inaccessible to wildlife.

Arctic-Wide Glaciers And Ice Caps Were Absent Or Smaller Than Today From 10,000 To 3000 Years Ago By Kenneth Richard on 29. August 2022

by K. Richard, Aug 29, 2022 in NoTricksZone

A new study details how a much warmer climate than today led to the disappearance of glaciers and ice caps during the sub-300 ppm CO2 Early to Middle Holocene. The Arctic’s modern ice extent is among the largest of the last 10,000 years.

Glaciologists Larocca and Axford (2022) have synthesized a comprehensive record of Arctic-wide glaciers and ice caps (GICs) situated near lakes for Greenland, Alaska, Arctic Canada, Iceland, Scandinavia, Svalbard, and the Russian Arctic.

They compared the current volume and extent of GICs to past Holocene periods when they were either 1) smaller than present or 2) absent, with the latter characterizations signifying greater Arctic warmth.

..;
…

Contrary to the popular view that the modern glacier and ice cap extents are unprecedentedly small or on the verge of disappearing for the first time ever, the authors found more than half the Arctic’s GICs that exist today either did not exist or were smaller than today from 10,000 to 3400 years ago, when atmospheric CO2 ranged between 260 and 270 ppm.

Furthermore, most (“80% or more”) were smaller than today or absent from 7900 to 4500 years ago, which was the peak of this interglacial’s Arctic warmth – multiple degrees Celsius warmer than today.

The following images from the paper document the “Percent of GICs smaller or absent” for each region over the course of the last 10,000 years or more. Notice that between 80% to 100% of GICs were smaller than today or absent from about 8000 and 4000 years ago, and that even the Roman and Medieval Warm Periods had lower GICs extent than today.

The largest glacier and ice cap extent of the Holocene has been realized in the last millennium, suggesting any recession of GICs in the last few centuries is but a partial return to a former period of much greater warmth.

Germany’s Alfred Wegener Institute Sees No Extreme Situation With Arctic Sea Ice

by P. Gosselin, July 22, 2022 in NoTricksZone

The Alfred Wegner Institute does not see an extreme situation with sea ice in the Arctic (June 2022). The institute’s page states:

The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is participating again this year with the AWI Consortium Model, a dynamic coupled sea ice ocean model, and calculated a September sea ice extent of 4.75 million square kilometers in its June forecast. This value is about 4% above the median value of all submitted models but in the middle of the predictions given for dynamic models.

Dr. Frank Kauker, a physicist in the Sea Ice Physics Section at AWI, assesses the first prediction as follows: “The first forecast of a year from the beginning of June is usually still characterized by a rather large uncertainty (this year 0.43 million square kilometers). Nevertheless, at the moment there is nothing to indicate an extreme situation in September.

The ice cover in September will be with a great probability in the range of the last years, i.e. between 4 and 5 million square kilometers. The next forecast in early July will reduce the uncertainty somewhat, as it will become clear in June how many melt ponds will have formed, which will then decisively determine the melt rates of the ice during the rest of the year due to their lower solar irradiance return.”
