Collect Targeted Data from Web Using Data Extractor Tools

The use of data to enhance your business prospects is a widely acknowledged fact. It is therefore very important that you have access to relevant data and not just any data in order to further your growth prospects. Utilizing the features and benefits of Web Scraper tools can help you achieve this goal effortlessly.

Customizing Web Extraction Tools for Your Business

The Internet is a maze of information repositories and identifying the right information from the right source may pose to be a major challenge. Moreover, data incorrectly sourced may result in erroneous analysis leading to a faulty strategy and slow growth for your business.  The risk is, however, considerably mitigated by employing Web extractor tools in your business processes and leveraging the advantages they provide.

Web extraction tools are used for the singular task of extracting relevant unstructured data from specific web sites and providing business users with a set of structured useable data. They perform this vital task with the help of scripting languages like python, Ruby, or Java. The biggest advantage of utilizing Web extraction tools is its ability to be customized as per the business requirement. This is easily achieved by defining the specific seed list you wish to scrape in the crawler script. A Seed list is the series of URLs that you wish to scan in order to extract the relevant data.  Thus defined, the crawler will scan only the targeted URLs. Along with the Seed list you can also specify the following relevant information to customize the scraper tool and ensure that it delivers as per your requirement. These defining parameters include:

•     Define the number of pages you wish the scraper to crawl
•     Define the specific file types you want the scraper to crawl
•     Define the type of data you would like to extract

This ensures that you can launch a focused search for the specific type of data that you wish to extract and also defines the appropriate source you want the crawler to access.

Benefits of using Targeted Data

Every business pertains to a specific domain. Its growth prospects, its revenue and its present standing are all defined by the demands and dynamics of that domain. Therefore, undertaking a study of its individual domain is one of the chief pre-requisites that your business must concentrate its efforts on in order to accelerate its growth. Moreover, through your business, you need to conduct a detailed analysis of competitive data in order to remain contextual in your specialized domain. Web Extractor tools have been equipped to understand this need and scrape pertinent data to foster growth patterns that strike the right chords. Some of the benefits leveraged from the extraction of targeted data include:

•     Updated financial information from competitor sites on stock prices and product prices helps you to estimate and launch competitive rates for your stocks and products
•     Studying market trends for a competitor’s products help you to position your product and plan your promotional campaigns effectively
•     Studying analytics of competitor websites will ensure that you are able to plan your web promotions in a far more effective way
•     Extracting data from blogs and websites that cater to your personal interests and hobby areas help you to build up your own knowledge repository which you can leverage to achieve benefits for your business as and when required.

Methane Levels Early 2015

The image below shows highest mean methane readings on one day, i.e. March 10, compared between three years, i.e. 2013, 2014 and 2015, at selected altitudes. The comparison indicates that the increase of methane in the atmosphere is accelerating, especially at higher altitudes.

The table below shows the altitude equivalents in mb (millibar) and feet.

56925 feet	44689 feet	36850 feet	30569 feet	25543 feet	19819 feet	14383 feet	8367 feet	1916 feet
74 mb	147 mb	218 mb	293 mb	367 mb	469 mb	586 mb	742 mb	945 mb

This rise in global mean methane levels appears to go hand in hand with much higher peak readings, especially at higher altitudes.

From January 1 to March 20, 2015, methane levels reached levels as high as 2619 ppb (on January 12, 2015), while peak daily levels averaged 2373 parts per billion (ppb). At the start of the year, global mean methane levels typically reach their lowest point, while highest mean levels are typically reached in September. Highest daily global mean methane levels for the period from January 1, 2015, to March 20, 2015, ranged from 1807 ppb (January 6, 2015) to 1827 ppb (March 5, 2015).

Further study of the locations with high methane levels indicates that much of the additional methane appears to originate from releases at higher latitudes of the Northern Hemisphere, in particular from the Arctic Ocean, from where it is over time descending toward the equator (methane will typically move closer to the equator over time as it rises in altitude, as discussed in this earlier post).

The largest source of additional methane appears to be emissions from the seabed of the Arctic Ocean. Annual emissions from hydrates were estimated to amount to 99 Tg annually in a 2014  post (image below).

The image below, based on data from the IPCC and the World Metereological Organization (WMO), with an added observation from a NOAA MetOp satellite image, illustrates the recent rise of methane levels and the threat that methane levels will continue to rise rapidly.

What causes these methane eruptions?

Methane eruptions from the seafloor of the Arctic Ocean appear to be primarily caused by rising ocean heat that is carried by the Gulf Stream into the Arctic Ocean. The image below shows sea surface temperatures of 20.9°C (69.62°F, green circle left) recorded off the coast of North America on March 14, 2015, an anomaly of 12.3°C (36.54°F).

Furthermore, both methane eruptions from the Arctic Ocean seafloor and demise of the Arctic sea ice and snow cover are feedbacks that can interact and amplify each other in non-linear ways, resulting in rapid and intense temperature rises, as illustrated by the image below.

Diagram of Doom - for more background, see Feedbacks

How high could temperatures rise?

Worryingly, a non-linear trend is also contained in the temperature data that NASA has gathered over the years, as described in an earlier post. A polynomial trendline points at global temperature anomalies of over 4°C by 2060. Even worse, a polynomial trend for the Arctic shows temperature anomalies of over 4°C by 2020, 6°C by 2030 and 15°C by 2050, threatening to cause major feedbacks to kick in, including albedo changes and methane releases that will trigger runaway global warming that looks set to eventually catch up with accelerated warming in the Arctic and result in global temperature anomalies of 16°C by 2052.

The situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan blog.

Diamond Mines And Mining Techniques

Diamonds remain to this day a mystical gem with a somewhat checkered past. The story of the Hope diamond is based on a long legend of misfortunes supposedly befalling its various and colorful owners. Segregation and mistreatment of blacks in diamond mines in Africa has long been a terrible mark on humanity in that part of the world. Although early white miners were treated better the working conditions endured by all diamond miners were less than humane. Fortunately most of today's mines while still depending on human labor have most of the heavy work done with machinery.

Contrary to popular belief diamonds are mined in areas other than Africa. Some of the better known diamond mines are these.

* Argye one of the Rio Tinto company mines is located in Western Australia.

* Diavik another Rio Tinto mine is located in Canada.

* Ekati owned by BHP Billiton and located in the Northwest Territories of Canada.

* Baken owned by Trans Hexis is located in South Africa.

* Merlin owned by Striker Resources is located in Australia.

* Orapa owned by a partnership between DeBeers and the government of Botswana is in Botswana.

* Premier owned by the De Beers Company is located in South Africa.

Diamond ore is extracted from these mines using basically four mining techniques which are based on the type of geology in which the diamond bearing material is located.

Marine Mining is the most recent development introduced about 1990. This technique is similar to deep water oil drilling. A large shaft is bored into the seabed to a depth where diamond bearing soil is located and that material is sucked to the surface. Also underwater vehicles called "crawlers" move along the seabed to scoop up diamond bearing gravel and pump it to the surface.

Placer Diamond Mining is a technique that is seen many times in movies of the old West. The diamonds are buried in river banks or mountain sides and water canons are used to wash the material down to be processed.

Hard Rock Diamond Mining is again familiar to movie fans as they watched coal miners or gold and silver miners digging their way into deep underground tunnels. Of course the technique is modern now and makes use of many specialized machines to do the heavy work.

Open-Pit diamond mining is similar to the pit coal mines of West Virginia and some western states. Overburden which is the soil covering the diamond embedded material is moved by machinery and blasting. The diamond bearing material is then moved to processing plants. This technique is common when the diamond bearing material is found close to the surface of if the geology is so unstable that tunneling is not safe or practical.

From this short article it should be apparent that diamonds take long and interesting journeys before they find a cherished spot on your finger or ear lobes.

Safeguarding the Future Through Data Mining

Web scraping can be a powerful tool not only in business and research. In fact, it has the capacity to protect the future by its predicting power. You may find this declaration incredible; but data mining is indeed a tangible way of predicting future events and thus protecting life in the future.

With the thousands of years of existence on earth, humans are able to gather as much information and experience to have a glimpse of what is to come. With the cycles of changes in the environment and in the whole universe aside from the human behavior, so much can be learned and applied.

At least three major things can be determined by careful and diligent data mining. These are: future threats; future trends; and future tactics.

Future threats

According to reports, the US intelligence agencies have been using web extraction as a way of studying the present and past terrorism acts and personages to predict future terrorist events. This has been actively done since the year 2010.

Data is gathered about a known terrorist such as: his activities; his contacts; his routines; the places he frequents; and other related information. These data are analyzed and classified. Any suspicious activities as well as unusual contact are monitored closely. Through these stored data and monitoring processes, any untoward activities can be precluded and preempted. You may say that terrorists can be using data mining too; and that is obviously possible. In this way, web scraping can also be used as a weapon for destruction. There is then a need for the government agencies to be very careful in protecting their data so that the enemies cannot retrieve them.

In the overall picture, you can just imagine how many lives, trauma, and damage can be prevented if future terrorist activities are prevented.

Moreover, climate change is another phenomenon that has already been predicted and is beginning to occur nowadays. Scientists have been studying the effects of global warming and environmental degradation through online data too. So much information drives and warning have been published by scholarly papers and by the experts but many of these have remained unheeded. Now that erratic weather conditions are happening, people can only regret and feel guilty that they are part of the cause of the problem.

However, it is not really too late to do some actions. People can avoid places where abnormal conditions are expected to happen; they can do some measures to protect themselves; and they can be informed ahead of time before anything catastrophic could happen.

Future trends

In relation to the predictions of possible threats, data extraction can also predict future trends. This is most helpful in businesses because they can be helped to produce items and employ strategies that will suit the expected patrons and clients.  Since history tends to repeat itself, data gathered in the past and present if studied judiciously and compared intelligently can bring in positive results.

Oftentimes, the companies that study their books as well as of those who have gone before them can gain more knowledge and expertise that will surely put them ahead of their contemporaries.

Future tactics

Naturally, along with knowing the possible events and trends in the future, strategies and ways to combat threats and cope with trends can also be predicted through web scraping.

Safeguarding the future is no longer a dream or wish. As early as today, experts can create equipment, structures, strategies, and even weapons to prevent any untoward incidents and collateral damage.

Studying the strengths and weaknesses of the past and present plans, procedures, and tools can lead to better technologies and techniques. The future can be a better and safer place if people can learn from the mistakes of the past and go from good to better.

The statement: “The best is yet to come,” will finally be realized if proper management of data and information collected and analyzed through web scraping will be conducted.

Bright future

Looking at the horizon, one can always expect the sun to shine and bring in a bright day. This same positive expectation for the future is indeed possible. Thanks to data mining; life can be handled more securely and precisely.

It does not mean that humans have become gods. It only proves that a person’s talents and skills, when used properly can make his/her future brighter and more successful. On the other hand, carelessness and lack of sensibilities to other people and the environment can surely bring in future doom.

Everything is laid bare and you are given the chance to handle the present with enough wisdom and capabilities. Although the world is too big to be understood and there is still a huge field of knowledge to be conquered, life can surely go on positively.

About Web Scraping and Web Data Mining

Web scraping as suggested by the name simply refers to method of obtaining data or information from an array of websites. This has greatly revolutionized how companies obtain data and put this obtained data into significant use.This has greatly helped many firms and individuals in different spheres transact in the most effective ways. With the internet offering a very large base for obtaining information, various companies have resorted to use web scraping as method of getting information. Relevance of needed data is of great importance since it is the determining factor of what and how data has to be scraped. A good number of data mining companies have come up to help individuals and organizations get the information as per their requirements. These companies also provide software which when installed in a computer may be of great importance to the business.

Depending on the organizations background it may opt to choose between mining the data for themselves or actually employing the services of a data mining company. These organizations have data mining experts who actually are better suited to handle data professionally. As it sounds it is not every ones job since it is computer languages that are used therefore it is only those with relevant knowledge that are well suited to handle this jobs.

Although short cuts are considered dangerous, in this case hiring the services of this experts may bring with it better results with minimized costs than doing the job internally What brings about the idea of a company going for a particular data mining company? For obvious reasons it may because of some eye catching advertisement somewhere. Mostly businesses do extensive research when it comes to making this choice and depending on the gravity sensitivity and format of sort data. These companies provide the needed data in the most comprehensive and in the needed format hence wastage of time as a resource is unheard in these businesses.

web scraping and data mining Research done by these companies ought to be converted to meaningful results. This is done by carrying out meaning full analysis and deducing relevant conclusions from this data. This operation greatly improves the efficiency of these organizations. Analysis done on this is carried by asking relevant questions regarding some aspects regarding the operations of the business. Questions that are frequently asked may take a certain form like, how viable could this be in the short run? In the quest of these answers it is then that meaningful analysis is done.

Data mining companies have given the business word a major boost in the accusation of data from the internet which may now be considered as the largest information resource. It also through this data mining that results from surveys across various parts of the world is acquired. This eliminates the need for this company carrying out these researches for themselves .Of particular importance is the aspect of language barriers making an individual company seeks the services of a reputable data mining firm. Therefore from all the above considerations it can be deduced that, if only a business is to achieve its objectives only proper web scraping techniques from reputable firms should be employed.

Web data mining refers to ways and methods which are used in seeking information from a wide array of websites. Companies and individuals employ this in their daily operations since in the current word lack of information can be a major setback. This is simply because it is through data mining that enterprises will be able to market their businesses, get information regarding upcoming promotions and sometimes make relevant discoveries. This explains why companies are investing lots of resources all aimed in the search of relevant information. After this organizations have gathered this information implementation of obtained information is vital. Therefore data mining should be coupled with relevant implementation to count it as a success. Analysis of information is quite important .Since bulky information obtained may not be necessarily required in that form. This is done using software that is capable of giving a good analysis of the data.

Analysis is done in different ways depending on requirements like one may require a summary or categorized data. Previously when data mining was not greatly used software developments were minimal .Recently there are great improvements in this field since many organizations are embracing it particularly those in third world countries. This has greatly improved turnovers of a good number of companies. Previously many firms used to collect data manually. This of course proved to be a very slow method and a tiring one. Many firms had to increase their staff to cope with this bulk in workload. Considering this age where capitalism is thriving they risked being faced out since it is the case where only the strongest survive and the weaker ones pave way. Time was a factor in realizing an increase in number of organization using this technologically advanced approach. Usage of this collected information is actually used to foster better growth of the company.

Based on previous findings from various analysis techniques are employed by the firms employees irrespective of their ranks. For examples managers may employ web data mining to make good and realistic decisions that are consistent or better than those which other companies are using. Information may also aid in improvement of business infrastructure since in the modern word infrastructure development is on the rise. Better infrastructure acquired on time will actually give the business a big thrust ahead of their competitors. With the relevant data mining software’s companies are able to do meaningful research and developments. For instance companies are able to address issues regarding their customers preferences, their individual wants .

A company may easily know who their customers are, what they are their likes and also their economic abilities. This can be used when the company decides to give offers, discounts and many other customer enticing actions. For example a soft drink company will have to place its promotions during winter since it is then that their customers are unlikely to buy their services. With this great increase in number of resources on the websites no individual can afford to ignore data mining.

Data Mining vs Screen-Scraping

Data mining isn't screen-scraping. I know that some people in the room may disagree with that statement, but they're actually two almost completely different concepts.

In a nutshell, you might state it this way: screen-scraping allows you to get information, where data mining allows you to analyze information. That's a pretty big simplification, so I'll elaborate a bit.

The term "screen-scraping" comes from the old mainframe terminal days where people worked on computers with green and black screens containing only text. Screen-scraping was used to extract characters from the screens so that they could be analyzed. Fast-forwarding to the web world of today, screen-scraping now most commonly refers to extracting information from web sites. That is, computer programs can "crawl" or "spider" through web sites, pulling out data. People often do this to build things like comparison shopping engines, archive web pages, or simply download text to a spreadsheet so that it can be filtered and analyzed.

Data mining, on the other hand, is defined by Wikipedia as the "practice of automatically searching large stores of data for patterns." In other words, you already have the data, and you're now analyzing it to learn useful things about it. Data mining often involves lots of complex algorithms based on statistical methods. It has nothing to do with how you got the data in the first place. In data mining you only care about analyzing what's already there.

The difficulty is that people who don't know the term "screen-scraping" will try Googling for anything that resembles it. We include a number of these terms on our web site to help such folks; for example, we created pages entitled Text Data Mining, Automated Data Collection, Web Site Data Extraction, and even Web Site Ripper (I suppose "scraping" is sort of like "ripping"). So it presents a bit of a problem-we don't necessarily want to perpetuate a misconception (i.e., screen-scraping = data mining), but we also have to use terminology that people will actually use.

September 2015 without Arctic Sea Ice?

The image below shows that Arctic sea ice extent, on March 8, 2015, was merely 14.263 square km.

What would happen if the Arctic sea ice kept falling to, say, under 11 million square km by end April and then followed a trajectory similar to 2012 for the next four months? As the animation below shows, such a scenario could wipe out all Arctic sea ice for more than a month from September 1st, 2015.

The following image is a contribution by Albert Kallio.

Sea ice thickness image, Naval Reserach Laboratory

Albert Kallio comments: "The latest sea ice thickness measurement (9th March 2015) for the US Navy submarines shows that the thick and rigid multiyear sea ice congestion has cleared from the Fram Strait between Greenland and the Svalbard Archipelago. That means sea ice is weak; new ice with saline residues and pack ice is made of numerous thin sea ice slabs that have been compressed to thick piles, rather than fewer thick slabs of multiyear sea ice. That means: more sea ice surface area is exposed to sea water and the heat within it. As a result, sea ice is likely melt even faster once it escapes from the Fram Strait. The wave penetration is also stronger within soft and highly fragmented seasonal ice packs. So, the sea ice is now primed for faster transport out of the Arctic Ocean."

So, what would happen if the sea ice was wiped out like that?

Sunlight that previously went into melting the sea ice, as well as sunlight that was previously reflected back into space by sea ice, would be absorbed by the Arctic Ocean instead. In other words, we can expect massive warming. In an earlier post, Prof. Peter Wadhams warned that warming due to Arctic snow and ice loss may well exceed 2 W per square m, i.e. it could more than double the net warming causing by all emissions by all people of the world.

Professor Peter Wadhams on albedo changes in the Arctic

The resulting temperature rise is likely to start wildfires all over the Northern Hemisphere, which would not only send huge amounts of greenhouse gases and soot into the air, but could also threaten entire cities and cause much of the grid to stop functioning. In 2007, a main power line burnt in Australia causing power outages for many homes and traffic lights in Melbourne. Many power plants require extensive water cooling, which can come under threat during intense heatwaves, as happened in France in 2009. Such events may be dwarfed by future heatwaves. Fuel is often transported by rail to power plants, and the railway tracks could bend during heatwaves. The health threat posed by heatwaves, wildfires and soot may result in critical employee loss at power plants.

As a result, electricity supply could stutter, and much industrial activity may stop, while there may be lots of traffic problems, etc. This is only one of the problems, though, as discussed in the 2007 post Ten Dangers of Global Warming. Food supply will come under threat due to crop loss and reduced supply of food to shops, made worse by traffic problems. As discussed back in 2011, much of the soot from firestorms in Siberia could settle on the ice in the Himalaya Tibetan plateau, melting the glaciers there and causing short-term flooding followed by rapid decrease of the flow of ten of Asia’s largest river systems that originate there, with more than a billion people’s livelihoods depending on the continued flow of this water.

Less industrial activity will not cause an immediate fall of tenmperatures, though. Instead, it would make that the aerosols that are currently sent up in the air by such activities and that are currently masking the full wrath of global warming, will fall out of the air in a matter of weeks. Until now, about half of the global temperature rise is suppressed by such aerosols. Stopping aerosols release overnight could make temperatures rise abruptly by 1.2°C (2.16°F) in a matter of weeks.

Methane eruptions from the seafloor of the Arctic Ocean typically start becoming huge around the end of October.

Conclusion from a paper presented at the 2008 EGU conference, on background
of a frame from a video interview by Nick Breeze with Natalia Shakhova.

Further warming of the Arctic Ocean could cause methane to erupt from the seafloor of the Arctic Ocean in quantities that could quickly double and tripple the amount of methane in the atmosphere.

The combined impact of such feedbacks could wipe out crops, deplete water supplies and make a huge number of species go extinct very quickly, including human beings.

In conclusion, the situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan blog.

4 Types of Mining and Quarry Equipment

You've surveyed the land, spent hours of painstaking research planning the process, and now you are ready to take your mining to the next level. The next phase of the journey will involve the proper equipment. There are several different types of equipment that go into mining. This article will cover some different types of mining equipment to get you started; and if you've already started, it will provide you with valuable knowledge to upgrade your equipment in the future.

Vibrating Feeder

A vibrating feeder is a type of linear direction feeding equipment. Vibrating feeders are widely used in mining and quarry operations and offer several features. Its features include smooth vibrating, dependable operation, and lengthy service life; most importantly, vibrating feeders are suitable for feeding. It consists of a vibrating frame, vibrator, spring, motor vibrating device and motor. The motor causes the vibrating feeder's shafts to rotate, which produces massive power and forces the feeder to vibrate. As the feeder vibrates, materials pass through its funnel and are screened. Common feeder applications include chemicals, minerals, coal, aggregates, and industrial materials.

Permanent and Self Cleaning Magnets

Both permanent and self cleaning magnets can be used on conveyor belts. A permanent magnet is built from a material that is magnetized and creates its own constant magnetic field. Permanent magnetic separators are used on conveyor belts when only limited levels of ferrous metals are expected to pass through. Self cleaning magnets are based on the technology of permanent and electro magnets. The purpose of self cleaning magnetic separators is to automatically remove and separate metallic and non metallic materials.

Forklifts

A forklift is an essential piece of equipment to any mining operation. Industrial forklifts can efficiently move mining supplies and material. Rough terrain forklifts can handle rugged conditions and still manage to perform well. With the standard attachments, a forklift can scoop, grip, pull, lift, scrape, clean, and load almost anything on a mine. Forklifts are extremely versatile and will increase the efficiency of your mining process.

Earthmoving and Construction Equipment

Earthmoving and construction equipment are essential to any mining or quarry operation. This equipment is often used in construction, turf, and excavation work. Examples of earthmoving and construction equipment include: backhoes, bulldozers, and dumpers. A backhoe loader is used for a wide range of jobs including excavating or breaking asphalt. A backhoe loader is a tractor with an arm linking a bucket to the front and a second arm attaching a backhoe in the rear. One benefit of a backhoe loader is that it is fairly small and versatile. A bulldozer is used to push heavy loads like sand from a demolished structure. It is usually much larger than a backhoe loader. A dumper is also designed to carry heavy loads, but these loads are usually in smaller quantities than those of a bulldozer. Backhoes, bulldozers, and dumpers are three types of earthmoving equipment that are critical to the success and efficiency of a mining or construction project.

These are some quarry, mining & construction Equipment in Perth and other places, which are quite essential and useful in these processes. Click on this link to get more information on other necessary equipment.

Save the Arctic sea ice while we still can!

The Arctic Ocean is coming close to complete summer meltdown, writes John Nissen - indeed it could happen as soon as September, triggering a severe deterioration in climate across the northern hemisphere. With fast-rising temperatures predicted in the coming decade, we must act now to save the Arctic, before it's too late.

---

By John Nissen

John Nissen: "Nothing has been said by the
IPCC. Nothing has been said in the
mainstream media. Nothing has been said
by the scientific community at large. This
is a terrible omission. It is quite scandalous."

Fossil fuel companies, and their supporters in government, seem blissfully unaware of the dangers ahead, threatening everybody on this planet.

The sea ice is declining far more rapidly than anyone expected. It is declining towards disappearance in summer months, yet the colossal negative impact of a low albedo Arctic has hardly been discussed. This is tragic because the whole situation could have been avoided with good leadership at negligible economic cost.

And as reported this week on The Ecologist, new scientific research indicates that the apparent 'pause' in global warming has, in fact, been no such thing. Instead the surplus heat - two Hiroshima bombs-worth a second - has simply been 'buried'
deep in the Pacific Ocean.

That's because of two important climate cycles, the Pacific Decadal Oscillation and the Atlantic Multidecadal Oscillation, whose operation has masked the warming. But soon they will tip the other way and the 'Big Heat' is set to begin - a five to ten year burst of rapid warming that will be most severe in the Arctic.

Commercial advantages for some ...

If you read the mainstream media, only the positive impact of a melting Arctic is mentioned: an Arctic ripe for exploitation.

Through not grasping the huge negative impact of a low albedo Arctic, the fossil fuel companies still appear entirely happy for the sea ice to disappear as quickly as possible - the sooner the better. Therefore they naturally resist any action to save the sea ice. In particular they don't want geoengineering deployed to cool the Arctic, because it might succeed in saving it!

Certain fossil fuel companies have already invested heavily in exploiting the vast store of oil and gas in the Arctic. These companies, and the governments who support them, are preparing for a bonanza when the sea ice disappears in summer: it will be so much easier and safer to extract the fossil fuel when the sea ice and freezing conditions have gone during summer months.

Furthermore, the disappearance of the sea ice will open up the Northwest Passage and the Northern Sea Route (formerly known as the Northeast Passage) to trade through summer months. So China and nations bordering the Atlantic (including the UK) are expecting to benefit enormously. Russia is investing heavily in ports and infrastructure to support the anticipated heavy traffic.

Various environment groups and the UK Environment Audit Committee have argued against drilling in the Arctic because they are concerned about oil spills and gas blow-outs which could ruin the local environment. They also seek to protect the wild life and Arctic ecosystem. But their arguing will be futile once the sea ice has gone in summer. It will be too late to protect the environment.

Environmentists have less concern about the opening up of the trade routes, because this will reduce CO2 emissions from transport of goods which at present have much longer journeys.

The Arctic bombshell is waiting to go off

While there is all this talk of exploiting the Arctic, little or nothing is said about the adverse effects of having an Arctic free of sea ice during summer months.

Nothing has been said by the IPCC. Nothing has been said in the mainstream media. Nothing has been said by the scientific community at large. This is a terrible omission. It is quite scandalous.

While most experts agree that there will come a time when the Arctic Ocean will be free of ice during summer months, there is no such agreement on the time-scale. Models suggest that it will take decades.

But observations of an exponential trend of sea ice decline suggest that this time could be within a decade. Scientific reports of especially rapid temperature rise in Alaska have also emerged. For example Barrow, Alaska, has experienced a 7°C temperature rise over 34 years, attributed to the decline in sea ice.

So what are the effects? During summer months, a vast area of reflective ice will have been replaced by open water, absorbing 90% of sunshine and warming the Arctic air above. It is clear that the Arctic will be warming much faster than at present - likely at over 2°C per decade.

As heat dissipates around the planet, there will be a huge contribution to global warming in the long term. Estimates put this at equivalent of 3.3 W/m2 (Flanner, 2011) or about twice the current warming from CO2.

But what are the immediate consequences of this super-rapid warming in the Arctic? At present we have an acceleration of three particular processes, affected by Arctic warming to date:

• Firstly, we have a dramatic rise in Northern Hemisphere weather extremes, as the jet stream behaviour is disrupted.
• Secondly we have an exponential increase in meltwater from the Greenland Ice Sheet, flowing through moulins on the surface of the ice into the sea and raising the sea level.
• And thirdly we have a dramatic increase in methane emissions from the Arctic Ocean seabed.

As the temperature in the Arctic continues to increase, these processes will continue almost indefinitely. We can expect worsening Northern Hemisphere climate causing widespread crop failures; faster sea level rise causing progressive flooding of low-lying regions; and growing methane emissions leading to even more catastrophic global warming.

These are three immediate results of the switching on of heat as the Arctic Ocean enters the low sea-ice state. The combination will be devastating for all mankind - with mass starvation and mass migration liable to trigger a world war.

This is the terrifying bombshell. The bonanza will be short-lived, as the effects of a seasonally ice free Arctic Ocean begin to bite.

For a few billion dollars a year, we can save the Arctic

Something must be done to prevent the ocean entering this low-ice state. Therefore the Arctic must be cooled enough to save the sea ice.

The first moment at the end of summer that the sea ice finally disappears from the ocean is called the 'blue ocean event'. It is significant because it could mark the entry of the ocean into a permanent low-ice state for subsequent years - the point of no return. The point of no return could be a soon as next September.

By any ordinary standards, we have left it too late to cool the Arctic. But any reduction in the risk of passing the point of no return is worthwhile, when all our futures are at stake.

Fortunately researchers are increasingly confident that a stratospheric aerosol haze, produced from sulphur dioxide, SO2, could provide significant cooling of the Arctic for modest expenditure of the order of a few billion dollars per year.

This type of cooling could be replaced by cloud brightening using ultra-fine seawater droplets when the technology is ready for large-scale deployment within a year or two.

There should be no significant negative economic impact from this action, except that the resources in the Arctic become frozen assets. But they should be frozen assets in any case if global warming is to be kept below 2°C, according to a recent paper.

There should be positive political impact, because governments will be working together in a common cause to protect their own citizens and all the citizens of the world. The fossil fuel industry has to be persuaded that preserving the Arctic sea ice is essential for the future of themselves and their stakeholders.

Objections from the anti-geoengineering lobby have to be overcome, because we have no other realistic option to reduce the colossal risk of passing a point of no return this September.

March 4, 2015 - Arctic Sea Ice Extent Hits Record Low

Sea surface temperature anomalies as high as 12°C (21.6°F) recorded off the east coast of North America have been described earlier, in he post 'Watch where the wind blows'. The Jet Stream reaching high speeds has also been described earlier, in the post 'Climate Changed'.

As feared, this is pushing warm water, water vapor and air from the North Atlantic into the Arctic Ocean. The three images below show forecasts for March 8, 2015, of - from top to bottom - the jet stream, surface winds and temperature anomalies.

Above image shows that the Arctic is forecast to reach a temperature anomaly of more than +4 degrees Celsius (more than +7 degrees Fahrenheit) on March 8, 2015, with temperature anomalies at the top end of the scale forecast for most of the Arctic Ocean.

On March 4, 2015, Arctic sea ice extent hit a record low for the time of the year, as illustrated by the image below.

As the March 5, 2015, Naval Research Laboratory image on the right illustrates, there is little scope for Arctic sea ice extent to grow over the next few weeks, since the only areas where it could possibly expand would be the Pacific and the North Atlantic, the very areas that are under pressure from ocean heat and high surface temperatures.

In other words, the situation looks set to deteriorate further.

Huge amounts of heat are still going into melting the sea ice. Furthermore, the sea ice is still able to reflect a lot of sunlight back into space. With continued demise of the snow and ice cover, more and more heat will be absorbed in the Arctic.

The big danger is that warm water will trigger further releases of methane from the seafloor of the Arctic Ocean. Peak daily methane levels recorded in early 2015 averaged a very high 2372 parts per billion, as illustrated by the image below.

Methane extent has been especially high over the Arctic Ocean. The images below are from the earlier post 'Temperature Rise'. The post added that, as the Gulf Stream keeps carrying ever warmer water into the Arctic Ocean, methane gets released in large quantities, as illustrated by the images below showing high methane levels over the East Siberian Arctic Shelf (red oval left) and over Baffin Bay (red oval right) with concentrations as high as 2619 ppb.

The images below show methane levels on Jan 25 (top), and Jan 26, 2015 (bottom).

Update:
Meanwhile, Arctic sea ice extent as reported by NSIDC.org reached a new record low for the time of the year with 14.358 million square km on March 4, 2015, and another record low with 14.308 million square km on March 7, 2015.

Temperature anomaly for the Arctic on March 8, 2015 (daily average) was even higher tha forecast, at +4.26 degrees Celsius, with peaks at +4.37 degrees Celsius.

High waves were registered in the North Atlantic on March 7, 2015, moving into the Arctic Ocean and causing waves more than 4 m high close to the edge of the sea ice on March 8, 2015.

The situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan blog.
