Summary:
Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study.

Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study by the University of Cincinnati.

The study by an international team of researchers was published in Nature Communications.

“The target is the sensitivity of sea ice to temperature,” said Won Chang, a study co-author and UC assistant professor of mathematics.

“What is the minimum global temperature change that eliminates all arctic sea ice in September? What’s the tipping point?”

The study predicted that the Arctic Ocean could be completely ice-free in September with as little as 2 degrees Celsius of temperature change. Limiting warming to 2 degrees is the stated goal of the 2009 Paris Agreement, the international effort to curb carbon emissions to address warming. The Trump Administration withdrew the United States as a participant in 2017……..

The less summer sea ice the Arctic has, the longer it takes for the Arctic Ocean to ice back over for the polar winter. That could spell bad news for Arctic wildlife such as seals and polar bears that rely on sea ice to raise pups and hunt them, respectively.

The researchers applied the new statistical method to climate model projections of the 21st century. Using the climate models, the authors found at least a 6% probability that summer sea ice in the Arctic Ocean will disappear with warming of 1.5 degrees above pre-industrial levels. At 2 degrees, the likelihood increases to 28%…….https://www.sciencedaily.com/releases/2019/08/190813160526.htm

Barents Observer report on Russian nuclear reactors in the Arctic

Nuclear fuel carrier “Serebryanka” remains inside closed-off waters near missile explosion site, Barents Observer, By Thomas Nilsen. August 09, 2019      “………Barents Observer report 

The Barents Observer has recently published an overview (pdf) listing the increasing number of reactors in the Russian Arctic. The paper is part of Barents Observer’s analytical popular science studies on developments in the Euro-Arctic Region.

According to the list there are 39 nuclear-powered vessels or installations in the Russian Arctic today with a total of 62 reactors. This includes 31 submarines, one surface warship, five icebreakers, two onshore and one floating nuclear power plants.

Looking 15 years ahead, the number of ships, including submarines, and installations powered by reactors is estimated to increase to 74 with a total of 94 reactors, maybe as many as 114. Additional to new icebreakers and submarines already under construction, Russia is brushing dust of older Soviet ideas of utilizing nuclear-power for different kind of Arctic shelf industrial developments, like oil- and gas exploration, mining and research.  “By 2035, the Russian Arctic will be the most nuclearized waters on the planet,” the paper reads.

Also, existing icebreakers and submarines get life-time prolongation. The average age of the Northern Fleet’s nuclear-powered submarines has never been older than today. Several of the submarines built in the 1980s will continue to sail the Barents Sea and under the Arctic ice-cap until the late 2020s.   https://thebarentsobserver.com/en/security/2019/08/severodvinsk-authorities-confirm-mysterious-brief-radiation-spike-after-missile

Unprecedented wildfires in the Arctic release huge CO2 to the atmosphere

Telegraph 27th July 2019 An unprecedented outbreak of wildfires in the Arctic has sent smoke across Eurasia and released more carbon dioxide in two months than the Czech
Republic or Belgium does in a year.

As 44C heatwaves struck Europe,
scientists observed more than 100 long-lasting, intense fires in the Arctic
in June, the hottest month on record, and are seeing even more in July,
according to Mark Parrington of the European Centre for Medium-Range
Weather Forecasts.

Mostly in Alaska and Russia, the infernos have
collectively released more than 120 million tonnes of CO2, more than the
annual output of most countries. It is the most carbon emitted since
satellite monitoring began in the early 2000s. This will further exacerbate
climate change and has sent smoke pouring toward more populated parts of
the world. Pollutants can persist more than a month in the atmosphere and
spread thousands of kilometres.

$70 trillion cost predicted, as Arctic permafrost thaws

Melting permafrost in Arctic will have $70tn climate impact – study  https://www.theguardian.com/environment/2019/apr/23/melting-permafrost-in-arctic-will-have-70tn-climate-impact-study  Jonathan Watts, Global environment editor  @jonathanwatts, 23 Apr 2019 

Study shows how destabilised natural systems will worsen man-made problem The release of methane and carbon dioxide from thawing permafrost will accelerate global warming and add up to $70tn (£54tn) to the world’s climate bill, according to the most advanced study yet of the economic consequences of a melting Arctic.

If countries fail to improve on their Paris agreement commitments, this feedback mechanism, combined with a loss of heat-deflecting white ice, will cause a near 5% amplification of global warming and its associated costs, says the paper, which was published on Tuesday in Nature Communications.

The authors say their study is the first to calculate the economic impact of permafrost melt and reduced albedo – a measure of how much light that hits a surface is reflected without being absorbed – based on the most advanced computer models of what is likely to happen in the Arctic as temperatures rise. It shows how destabilised natural systems will worsen the problem caused by man-made emissions, making it more difficult and expensive to solve.

They assessed known stocks of frozen organic matter in the ground up to 3 metres deep at multiple points across the Arctic. These were run through the world’s most advanced simulation software in the US and at the UK Met Office to predict how much gas will be released at different levels of warming. Even with supercomputers, the number crunching took weeks because the vast geography and complex climate interactions of the Arctic throw up multiple variables. The researchers then applied previous economic impact models to assess the likely costs.

Melting glaciers causing sea levels to rise at ever greater rates

 https://www.eurekalert.org/pub_releases/2019-04/uoz-mgc040419.php

UNIVERSITY OF ZURICH 8 Apr 19, Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise. Glaciers alone lost more than 9,000 billion tons of ice since 1961, raising water levels by 27 millimeters, an international research team under the lead of the University of Zurich have now found.

Glaciers have lost more than 9,000 billion tons (that is 9 625 000 000 000 tons) of ice between 1961 and 2016, which has resulted in global sea levels increasing by 27 millimeters in this period. The largest contributors were glaciers in Alaska, followed by the melting ice fields in Patagonia and glaciers in the Arctic regions. Glaciers in the European Alps, the Caucasus and New Zealand were also subject to significant ice loss; however, due to their relatively small glacierized areas they played only a minor role when it comes to the rising global sea levels.

Combination of field observations and satellite measurements

For the new study, the international research team combined glaciological field observations with geodetic satellite measurements. The latter digitally measure the surface of the Earth, providing data on ice thickness changes at different points in time. The researchers were thus able to reconstruct changes in the ice thickness of more than 19,000 glaciers worldwide. This was also possible thanks to the comprehensive database compiled by the World Glacier Monitoring Service from its worldwide network of observers, to which the researchers added their own satellite analyses. “By combining these two measurement methods and having the new comprehensive dataset, we can estimate how much ice has been lost each year in all mountain regions since the 1960s,” explains Michael Zemp, who led the study. “The glaciological measurements made in the field provide the annual fluctuations, while the satellite data allows us to determine overall ice loss over several years or decades.”

335 billion tons of ice lost each year

The global mass loss of glacier ice has increased significantly in the last 30 years and currently amounts to 335 billion tons of lost ice each year. This corresponds to an increase in sea levels of almost 1 millimeter per year. “Globally, we lose about three times the ice volume stored in the entirety of the European Alps – every single year!” says glaciologist Zemp. The melted ice of glaciers therefore accounts for 25 to 30 percent of the current increase in global sea levels. This ice loss of all glaciers roughly corresponds to the mass loss of Greenland’s Ice Sheet, and clearly exceeds that of the Antarctic.

It is now inevitable that Arctic temperatures will rise sharply

Earth Spasms from Profoundly Abrupt Climate Change

Sharp rise in Arctic temperatures now inevitable – UN https://www.theguardian.com/environment/2019/mar/13/arctic-temperature-rises-must-be-urgently-tackled-warns-uFiona Harvey, Environment correspondent 14 Mar 2019

Winter temperatures at the north pole are likely to rise by at least 3C above pre-industrial levels by mid-century, and there could be further rises to between 5C and 9C above the recent average for the region, according to the UN.

Such changes would result in rapidly melting ice and permafrost, leading to sea level rises and potentially to even more destructive levels of warming. Scientists fear Arctic heating could trigger a climate “tipping point” as melting permafrost releases the powerful greenhouse gas methane into the atmosphere, which in turn could create a runaway warming effect.

“What happens in the Arctic does not stay in the Arctic,” said Joyce Msuya, the acting executive director of UN Environment. “We have the science. Now more urgent climate action is needed to steer away from tipping points that could be even worse for our planet than we first thought.”

The findings, presented at the UN Environment assembly in Nairobi on Wednesday, give a stark picture of one of the planet’s most sensitive regions and one that is key to the fate of the world’s climate.

Last year’s stark warnings from the Intergovernmental Panel on Climate Change, setting out the dramatic impacts of 1.5C of global warming, did not include the impacts of potential tipping points such as melting permafrost.

If melting permafrost triggers a tipping point, the likely results would be global temperature rises well in excess of the 2C set as the limit of safety under the Paris agreement. Nearly half of Arctic permafrost could be lost even if global carbon emissions are held within the Paris agreement limits, according to the UN study.

Even if all carbon emissions were to be halted immediately, the Arctic region would still warm by more than 5C by the century’s end, compared with the baseline average from 1986 to 2005, according to the study from UN Environment.

That is because so much carbon has already been poured into the atmosphere. The oceans also have become vast stores of heat, the effect of which is being gradually revealed by changes at the poles and on global weather systems, and will continue to be felt for decades to come.

The assembly heard that there was still a need to fulfil the aims of the 2015 Paris agreement on climate change and to take further action that could stave off some of the worst effects of warming in the near term. “We need to make substantial near-term cuts in greenhouse gas emissions, black carbon and other so-called short-lived climate pollutants all over the world,” said Kimmo Tiilikainen, Finland’s environment minister.

Making drastic cuts to black carbon and short-lived pollutants such as methane could reduce warming by more than 0.5C, according to previous research.

Where climate threat and nuclear threat meet: Top Secret US Cold War Nuclear Base in Greenland

Melting Ice Sheets Could Reveal Top Secret US Cold War Nuclear Base https://www.iflscience.com/environment/melting-ice-sheets-could-reveal-top-secret-us-cold-war-nuclear-base/ 11 Mar 19, Among the many Bond villainesque plans dreamed up during the Cold War, few come stranger than “Project Iceworm,” the shady US program to build a network of top secret nuclear missile launch sites beneath the Danish territory of Greenland. The largest and most impressive of the US bases was Camp Century, a warren of tunnels and labs under northwest Greenland’s ice sheet that was powered by its own portable nuclear reactor.

After just eight years of operation, Camp Century was decommissioned in 1967 due to engineering woes and a political scandal centered on whether Denmark had actually given the US full permission to house nuclear materials in their territory.

As the Cold War ended, the base was largely forgotten, not least because it was hoped to remain “preserved for eternity” under a blanket of snow and ice. However, with climate change knocking at the door, it looks like a different kind of thaw could reveal all.

A study published in 2016 used simulations to show that the ice above and around Camp Century could thaw by 2090 under a “business-as-usual” climate change scenario. Not only would this unearth the once-secret abandoned military base, but it also holds the potential to let loose the huge amounts of chemical and nuclear waste left at the site. These pollutants could leech into the surrounding surface water and spark a plethora of problems for the island’s human population and ecosystem.

Another study, published last year in the journal Global Environmental Politics, took a further look at the situation at Camp Century, arguing it has the potential to fire up some long-frozen geopolitical tensions. It’s not very clear how much Denmark knew about the US’ plans in Greenland. While they agreed the US could have the Thule Air Base in northwest Greenland, the issue of nuclear weapons in Danish territory was a big no-no. To make matters even thornier, Greenland has since transitioned to a self-governing overseas administrative division of Denmark.

If the climatic scenario predicted does hit, as anticipated, who will be responsible for the clean-up of toxic chemicals and radioactive materials?

As the study argues, Camp Century is not the only problem. This scenario serves as just one example of how climate change could trigger a huge number of unforeseen consequences in international politics, especially when it comes to overseas military bases.

“The case could be the proverbial canary in the coal mine for future politics surrounding overseas military bases,” according to study author Jeff Colgan.

“Climate change can create knock-on environmental problems associated with a military base’s infrastructure or waste that disrupt the international politics that govern the base,” he wrote in the study. “Any cleanup costs or compensation related to the knock-on environmental problems create an unfunded liability for the host country, the country operating the base, or both.”

This is just another unexpected fallout of the climate issue we’re facing that needs to be dealt with sooner rather than later.
