    If nothing else, we can all agree CO2 causes heavy breathing that leads to no breathing. Can we?

    Ship-to-shore Cranes Shipped via The Northern Sea Route

    by Michelle Howard
    January 4, 2017

    HANSA HEAVY LIFT has transported the first-ever ship-to-shore (STS) cranes via the Northern Sea Route (NSR), relocating them from the port of St Petersburg to the port of Vostochny, spanning both the European and Far East regions of Russia.

    HHL Valparaiso is the first vessel to sail open hatch through the Northern Sea Route, which is covered by thick ice for most of the year and has a limited window of about two months open to cargo voyages.

    This allowed the two cranes, each weighing 820 metric tonnes and measuring 61 meters in height and 92 metres in width, to be shipped partially above and below deck.

    “The Northern Sea Route was the only viable option to complete this voyage in the required timeframe,” said Gleb Faldin, Commercial Manager, HANSA HEAVY LIFT.

    “In the Arctic there is no room for mistakes. During the passage, the vessel has limited connection and only a few points of shelter.

    “It is important to understand the legal framework to navigate the NSR, to plan carefully, to be prepared for the unexpected, and most importantly to have the right team on board the vessel and in the office.”

    Faldin added that a two-month delay in the cargo being ready meant that HHL Valparaiso had to be repositioned for the voyage, which was originally planned for HHL Tokyo.

    HHL Valparaiso travelled from Qingdao, China to St Petersburg via the NSR to load the cranes, and then went back through the NSR a second time to complete the mission, which was accomplished in record time.

    Crews had only a few weeks to complete the voyage, as the cargo was loaded in October and had to be delivered to its destination by late November before the route completely froze over.

    Other challenges included limited space aboard the HHL Valparaiso, which holds Ice Class E3 equivalent to Russian Arc.4 (Finnish- Swedish Ice Class 1A).

    Additionally, the cranes were not designed to be lifted, requiring careful planning from all parties involved in the move, as well as strong engineering expertise.

    “The Northern Sea Route is an important alternative that can save weeks from a voyage, but to be successful you need careful planning and engineering, the right equipment, capable vessels, and experienced crews,” said Heinrich Nagrelli, Project & Transport Engineer, HANSA HEAVY LIFT.

    “Due to the STS’s very high center of gravity (CoG) at 30 meters above deck and 70 meters air draft, as well as draft restriction of 7.7 meters, a careful and detailed plan was needed from the start.

    “This included a load spreading design and a structural analysis of the hatch covers and lower hold, a lifting stability assessment, a lifting simulation, fulfilment of Flag State requirements (open hatch, visibility, arctic weather conditions, COLREGs*), and the approval of the Russian Maritime Register of Shipping, as well as the arranging of ice breaker assistance.”

    ZAO ‘SMM’, a leading manufacturer of heavy port handling equipment in Russia, was charterer of the HHL Valparaiso and in charge of overall project management as well as the transportation of the two STS cranes.

    “The high professionalism of ZAO ‘SMM’ and good mutual cooperation with HANSA HEAVY LIFT ensured the successful and timely implementation of this project,” said Mikhail Skripchenko, Project Manager at ZAO ‘SMM’.

    “Our company has proven expertise in the area of logistics for the transport of heavy cranes and other oversized equipment via Russian inland waterways, as well as the Northern Sea Route.


    All HANSA HEAVY LIFT vessels can travel along sea routes with an ice thickness of up to 0.8 meters.

    They don't make enough coffee for that.

    I am not a mariner, but it seems reckless to operate with open hatches in Arctic water without employing some other means of displacing most of the water that might enter if they encounter unavoidable foul weather, maybe use some sort of air bladders captivated by heavy netting.

    Retreating Arctic Coasts Cause Drastic Changes

    By Joseph R. Fonseca
    January 4, 2017
    Marine Technology News


    The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20 meters of land per year at some locations. The earth masses removed in this process increasingly blur the shallow water areas and release nutrients and pollutants. Yet, the consequences of these processes on life in the coastal zone and on traditional fishing grounds are virtually unknown.

    Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) urge to focus our attention on the ecological consequences of coastal erosion in the January issue of the journal Nature Climate Change. According to the scientists, an interdisciplinary research program is required, and must involve policy-makers as well as inhabitants of the Arctic coasts right from the onset.

    The difference could hardly be greater. In the winter, when the Beaufort Sea is frozen around the Canadian permafrost island of Herschel Island (Qikiqtaruk), the sea water in the sample bottles of the AWI researcher Dr. Michael Fritz looks crystal clear. In summer, however, when the ice floes are melted and the sun and waves start to wear the cliff away, the water sample of the Potsdam geoscientist contains a cloudy broth.

    "Herschel Island loses up to 22 meters of coast each year. The thawed permafrost slides down into the sea in the form of mud slides and blurs the surrounding shallow water areas so much that the brownish-grey sediment plumes reach many kilometers into the sea," reports the polar researcher.

    His observations of Herschel Island can now be transferred to large parts of the Arctic. 34 percent of the coasts around the world are permafrost coasts. This means, especially in the Arctic, that its soil contains a large amount of frozen water, which keeps the sediments together like cement. If the permafrost thaws, the binding effect fails. The sediments as well as animal and plant remains, which are frozen in the permafrost, are suddenly released in the water and are washed away by the waves.

    In this process, greenhouse gases such as carbon dioxide and methane are released and lead to even greater global warming. The eroded material also contains a lot of nutrients and pollutants such as nitrogen, phosphorus or mercury. These substances enter the sea, where they are further transported, degraded or accumulated and permanently alter the living conditions in the shallow water area. "We can until now only guess the implications for the food chain. To date, almost no research has been carried out on the link between the biogeochemistry of the coastal zone and increasing erosion and what consequences this has on ecosystems, on traditional fishing grounds, and thus also on the people of the Arctic," says Michael Fritz.

    For this reason, Michael Fritz, the Dutch permafrost expert Jorien Vonk and AWI researcher Hugues Lantuit call on the polar research community to systematically investigate the consequences of coastal erosion for the arctic shallow water areas in the current issue of the journal Nature Climate Change. "The processes in the arctic coastal zone play an outstanding role for four reasons. Firstly, the thawed organic material is decomposed by microorganisms, producing greenhouse gases. Secondly, released nutrients stimulate the growth of algae, which can lead to the formation of low-oxygen zones. Thirdly, the addition of organic carbon increases the acidification of the sea, and fourth, the sediments are deposited on the seabed or are transported to the open ocean. This has direct consequences for the biology of the sea," the authors say.

    The urgency of the topic also increases with the warming of the Arctic: "We believe that the erosion of the Arctic coasts will increase drastically as a result of rising temperatures, the shrinking of the protective sea ice cover, and the rising sea level," says AWI permafrost expert and co-author Professor Hugues Lantuit. He adds that “during the ice-free season the waves can hit the coast higher and affect more land”. An erosion of that magnitude will without a doubt alter the food web in the coastal zone, and will affect those people who depend on fishing and who cultivate their traditional way of life along Arctic coasts.

    The main reason why research on this topic has not been carried out so far is linked to logistics. Much of the arctic coastal and shallow water zones are not accessible either by car or plane, or by large icebreakers. There is also no arctic-wide station network at the coast that could be used by researchers to collect reliable data. “Politics and science must find common solutions here, for example within the framework of the EU research program Horizon 2020. In order to make concrete statements on the consequences of erosion, we need an interdisciplinary research program that includes policy-makers and the Arctic population from the beginning,” says Michael Fritz.

    1750? So the climate would not have changed on itself, but would have just frozen for 250 years? Not a single change anywhere?

    The "put them in jail" meme has been running for a while, the mainstream warming cult is leery of it though because they know what comes round goes round and in another five years they'll need a soft landing as their con game gets undone.

    Greenpeace Claims Immunity from Lawsuits Because Its Claims Are ‘Hyperbole’

    There’s been an interesting twist of events involving Greenpeace, one of the major groups pushing the failing #ExxonKnew campaign: They’ve been sued by Resolute, a Canadian forest-products company, for defamation and false claims about the company’s operations.

    But when Greenpeace had to answer for its actions in court, the group wasn’t so sure it could defend its claims. In fact, they admitted those claims had no merit. As Resolute’s President and CEO Richard Garneau explained in a recent op-ed,

    A funny thing happened when Greenpeace and allies were forced to account for their claims in court. They started changing their tune. Their condemnations of our forestry practices “do not hew to strict literalism or scientific precision,” as they concede in their latest legal filings. Their accusations against Resolute were instead “hyperbole,” “heated rhetoric,” and “non-verifiable statements of subjective opinion” that should not be taken “literally” or expose them to any legal liability. These are sober admissions after years of irresponsible attacks. (emphasis added)
    No “forest loss” was caused by Resolute, the groups concede — now that they are being held accountable.

    As the Financial Post also reported,

    But now Greenpeace says it never intended people to take its words about Resolute’s logging practices as literal truth.

    “The publications’ use of the word “Forest Destroyer,” for example, is obvious rhetoric,” Greenpeace writes in its motion to dismiss the Resolute lawsuit. “Resolute did not literally destroy an entire forest. It is of course arguable that Resolute destroyed portions of the Canadian Boreal Forest without abiding by policies and practices established by the Canadian government and the Forest Stewardship Council, but that is the point: The “Forest Destroyer” statement cannot be proven true or false, it is merely an opinion.”
    In other words, Greenpeace is admitting that it relies on “non-verifiable statements of subjective opinion,” and because its claims are not meant to be factual, the group believes it cannot be held legally responsible for what it says.

    Notably, Greenpeace has been actively pushing for legal action against ExxonMobil, alleging the company “knew” about climate change in the 1970s and 1980s before the world’s top scientists had come to any solid conclusions. When the Rockefeller-funded InsideClimate News and Columbia School of Journalism produced their #ExxonKnew hit pieces, Greenpeace immediately called for the Department of Justice to investigate ExxonMobil, saying,

    “The Department of Justice should open a federal investigation immediately and hold the company legally accountable for misleading the public, lawmakers, and investors about the impacts of climate change. A DOJ investigation should be broad and look into the role of other fossil fuel companies, trade associations, and think tanks in sowing doubt about the risks of climate change.” (emphasis added)
    Greenpeace claims it cannot be sued because its misleading claims were not meant to be factual, but it then claims the U.S. Department of Justice needs to investigate an energy company for what it calls “misleading the public.”

    It will come as no surprise that Greenpeace is also funded by the Rockefeller Brothers Fund and Rockefeller Family Fund, the same groups that have been bankrolling #ExxonKnew every step of the way.

    Representatives from Greenpeace were in attendance at a secret strategy meeting in January 2016, held at the Rockefeller Family Fund offices in New York, where the activists met to brainstorm how “to establish in public’s mind that Exxon is a corrupt institution,” “delegitimize them as a political actor,” and “force officials to disassociate themselves from Exxon.”

    A former member of Greenpeace’s Board of Directors, Kenny Bruno, last year tweeted,

    “I don’t want to abolish Exxon. I simply want to reduce it to the size where I can drag it into the bathroom and drown it in the bathtub.”
    If it wasn’t already abundantly obvious, these latest developments just go to show how much credulity Greenpeace has.

    A sane analysis of ways forward in regard to climate policy.

    Since I’ve argued that the cost/benefit approach doesn’t really make sense for such a wicked problem with massive uncertainties, does this mean I think we should ignore the problem?

    NO, we should not ignore the problem, but we should reframe it in ways that put some realistic bounds on what we are dealing with– not just climate change, but also population increase and concentration of wealth in vulnerable coastal regions. Not to mention the growing needs of this increasing population for energy, water and food.

    I would challenge the policy making community and the science-policy interface communities to consider the following questions and proposed analyses:

    1.How many different combinations of assumptions in the SCC models can produce a SCC value that is not significantly different from zero, or within some ‘tolerable’ limit?

    2.Imagine the worst plausible future climate outcome on the time scale of the 21st century (consistent with the AR5), and estimate the damages in the 21st century. Assess whether any conceivable path of CO2 emissions reductions in the 21st century would make a significant dent in those damages.

    3.Estimate the costs of extreme weather in the 21st century, based on weather statistics from the 20th century while accounting for 21st century changes in population, demographic, property, GDP, etc. Then compare the impact of socioeconomic changes on 21st century costs relative to the hypothetical delta of extreme weather events as derived from climate models. I wouldn’t be surprised if population increase and concentration of wealth in coastal regions is a much bigger factor here than climate change.

    4.Estimate the costs of sea level rise in the 21st century based on three different assumptions: 1) applying the average sea level rise rate over the 20th century; 2) applying the average rate of sea level rise for the past 50 years for each coastal location, which also includes land use, geologic factors, groundwater withdrawal, etc.; 3) apply the average rate of sea level rise from the IPCC AR5. I suspect that #2 will be associated with the most damage, since the most vulnerable locations have local sea level rise rates that far exceed anything that can be explained by warming. Apart from geologic and land use effects on sea level rise, the increase of population and concentration of wealth in coastal regions may also be a bigger factor than sea level rise associated with warming.

    5. Estimate regional per capita water needs (globally), using population and socioeconomic projections for the 21st century. Compare that with 20th century water availability (total and per capita). Estimate the per capita water availability in the 21st century using climate models. Is the decline in 21st century per capita water availability caused by population increase or climate change? (Hint: whether or not you find them convincing, climate models predict overall MORE rainfall in a warmer climate; melting glaciers will help at least in the short term.) Assess the costs of meeting per capita water needs using 20th century rainfall versus 21st century projected rainfall.

    6.Based on estimates from #3, #4, #5, decide on how much resilience we can afford, in terms of infrastructure, and work on other clever ways to reduce your vulnerability through land use policies, advance warning of severe weather, etc.

    This list is by no means exhaustive; once you think about reframing the climate problem and the solutions, lots of new ideas pop up. Such analyses would provide the basis for a pragmatic climate policy that puts people first in the 21st century, which is a reasonable thing to do given the deep uncertainties surrounding the wicked climate change problem. Any rationale that supports rapid reductions of CO2 emissions needs to provide pathways for improved technologies for energy, transportation, agriculture, etc. Not to mention supporting human development in regions that currently do not have access to grid electricity.

    The bottom line is: water, food, energy. Heck, even the folks attending Davos get it [link]. People need it and large numbers of people want more of it. And there are more and more people all the time. A single minded focus on reducing CO2 emissions neglects a lot of real problems facing many nations across the globe.

    Climate variability and change impacts water, food and energy. But there isn’t much we can do to influence the climate on the timescale of the 21st century — however much we have impacted the climate over the past 70 years or so, those impacts (large or small) will work their way through climate system over the next centuries as the oceans act as a big flywheel on the climate system.

    Back to the question posed by Revkin: Will Trump’s climate team accept any social cost of carbon? Well, I hope not. Here’s to hoping for a more pragmatic approach to all this in the Trump administration.
    see full article for discussion on attempts to analysis emission reductions via a cost/benefit approach.

    https://judithcurry.com/2017/01/17/r...ost-of-carbon/

    To me, it's just plain obvious, we have much bigger environmental related issues in the 21st century than man-made climate change.
