The backend data repository is based on MySQL. Therepository contains 16 tables that captures the varioussource information described above. The current size of therepository (excluding the real-time data) is 92 MB.

Provider maps often contain additional information aboutnetwork node resources. This information can range from lo-cation (potentially down to Lat/Lon coordinates), to IP ad-dresses, to resource or service types. Our ability to extractnetwork node information from the discovered resources isdependent on an assembly of scripts that include Flash-based extraction and parsing tools [3], optical characterrecognition parsing tools [7], PDF-based parsing tools [8],in addition to standard text manipulation tools. This li-brary of parsing scripts can extract information and enterit into database automatically. For instances where none ofthe tools or scripts are successful on the provider data, wemanually parse and enter the data.

Visualization-centric representations often reveal no in-formation about link paths other than connectivity (e.g.,line-of-sight abstractions are common). For these we en-ter the network adjacency graph by hand into Atlas. How-ever, some maps provide highly detailed geographic layoutsof fiber conduit connectivity (e.g.,Level3 [5]). We transcribethese, maintaining geographic accuracy, into the Atlas us-ing a process and scripts that(i)capture high resolutionsub-images,(ii)patch sub-images into a composite image,(iii)extract a network link image using color masking tech-niques,(iv)project the link-only image into ArcGIS usinggeographic reference points (e.g.,cities), and(v)use linkvectorization in ArcGIS to enable analysis (e.g.,distanceestimation) of the links.

In addition to Internet search, we appeal to the largenumber of existing Internet systems and publicly availabledata they provide. This includes PeeringDB [9], NetworkTime Protocol (NTP) servers, Domain Name System servers(DNS), listings of Internet Exchange Points (IXPs), Look-ing Glass servers, traceroute servers, Network Access Points,etc.Beyond their intrinsic interest, it is important to rec-ognize that NTP servers [6] often publish their Lat/Lon co-ordinates and are typically co-located with other network-ing/computing equipment. Similarly, DNS servers routinelypublish their location via the LOC record [18]. In total, over4,700 network resources of various types are annotated inthe Internet Atlas database.

Third, the de facto useof IP addresses gathered from TTL-limited probing cam-paigns as the basis for inferring structure has inherent diffi-culties. These include the well known interface disambigua-tion problem [26], widely varying policies on probe blockingamong providers, and difficulties in managing large scalemeasurement infrastructures [24]. We believe that a differ-ent approach to building and maintaining a repository ofInternet maps is required.

Given the large number of nodes and miles of fiberconduit that are at risk, the key takeaway is thatdevelopingmitigation strategies should begin soon.

To localize overlap we develop a Coastal Infrastructure Risk(CIR) metric that highlights the concentration of Internetinfrastructure per geographic location (e.g., city). The CIRmetric will be used to elucidate the impact of sea level riseon Internet assets temporally. Using CIR, we identify the top10 major geographic locations most at risk, and thus in needof action by municipalities and service providers to secureexisting deployments and plan for new deployments.

We also quantify therisks to individual service provider infrastructures and findthat CenturyLink, Inteliquent, and AT&T are at highest risk.

In this paper we consider the risks to Internet infrastructurein the US due to sea level rise. Our study is based on sealevel incursion projections from the National Oceanic andAtmospheric Administration (NOAA) [12] and Internet in-frastructure deployment data from Internet Atlas [24]. Wealign the data formats and assess risks in terms of the amountand type of infrastructure that will be under water in dif-ferent time intervals over the next 100 years. We find that4,067 miles of fiber conduit will be under water and 1,101nodes (e.g.,points of presence and colocation centers) willbe surrounded by water in the next 15 years.

Mark Parrington, a senior scientist at the European Centre for Medium-Range Weather Forecast, said the amount of CO2 emitted by Arctic wildfires between 1 June and 21 July 2019 is around 100 megatonnes and is approaching the entire 2017 fossil fuel CO2 emissions of Belgium.

It is this combination of features that also makes HyperCard a powerful hypermedia system. Users can build backgrounds to suit the needs of some system, say a rolodex, and use simple HyperTalk commands to provide buttons to move from place to place within the stack, or provide the same navigation system within the data elements of the UI, like text fields. Using these features, it is easy to build linked systems similar to hypertext links on the Web.[5] Unlike the Web, programming, placement, and browsing were all the same tool. Similar systems have been created for HTML but traditional Web services are considerably more heavyweight.

The web, in yet another example of its leveling effect, allows nearly everyone to see nearly every interface. Thus designers can learn rapidly from what others have done, and users can see if one web site's experience is substandard compared to others.

Air pollution contributed to nearly one in every 10 deaths in 2017, making it a bigger killer than malaria and road accidents and comparable to smoking, according to the State of Global Air (SOGA) 2019 study published on Wednesday. In south Asia, children can expect to have their lives cut short by 30 months, and in sub-Saharan Africa by 24 months, because of a combination of outdoor air pollution caused by traffic and industry, and dirty air indoors, largely from cooking fires. In east Asia, air pollution will shorten children’s lives by an estimated 23 months. However, the life expectancy burden is forecast to be less than five months for children in the developed world.

Reading on the web is a critical skill for engaging content online.

Good online readers know the tools and strategies that can be used to search for and locate people, resources, and information. They then know how to judge the credibility of these sources.1 The web literacy skills and competencies identified under reading on the web are as follows. Search

Only people with nothing to fear see the idea of a completely connected world as unequivocally good

Despite the existence of these two contradictory trends, even the most optimistic studies express concerns regarding the capacity of technological progress to counter the growth in volumes by 2020.For example, this report from the American Department of Energy and the University of California on the energy consumption of data centers in 2016 in the United States, states:"The key levers for optimizing theenergy efficiency [of data centers] identified in this report, better PUE, better rate of use of servers and more linear consumption all have theoretical and practical limits and the amount of progress already achieved suggests that these limits will be reached in the relatively near future."(Shehabi, A. et al., 2016)

India plans to launch a massive program to deploy commercial 5G networks in 2020 to boost the performance and capacity of existing mobile networks, taking into account that the 4G networks (which only took off in 2017 due to a price war over data started by the telecommunications operator Reliance Jio)are making big advances towards general coverage.

We have therefore sought to identify levers of action more closely related to the demand and consumption of digital services than on the energy efficiency of supply.

However, emerging organizations are starting to build bridges into the old technology in an effort to re-decentralize.

Is it possible to reverse the deterioration we are experiencing today? I spoke with individuals who are working actively within the values of the decentralized web and are building towards this panacea.

The future we're fighting for has no analog in mainstream tech, and so it's hard to articulate our strategy using their words. I know that we can feel it, though-- when a new person suddenly gets what we are attempting to do, it is like two instruments slowly coming into tune.

Last year, Google quietly started an oil, gas, and energy division. It hired Darryl Willis, a 25-year veteran of BP, to head up what the Wall Street Journal described as “part of a new group Google has created to court the oil and gas industry.” As the VP of Google Cloud Oil, Gas, and Energy, Willis spent the year pitching energy companies on partnerships and lucrative deals. “If it has to do with heating, lighting or mobility for human beings on this planet, we’re interested in it,” Mr. Willis told the Journal. “Our plan is to be the partner of choice for the energy industry.”

The hurdle we face today is not lack of skill, it's depression

Avant-Pop artists welcome the new Electronic Age with open arms because we know that this will vastly increase our chances of finding an audience of like-minded individuals who we can communicate and collaborate with

Soon the Data Superhighway will finally once and for all do away with the high-priced middlemen, and artists will reap the benefits of their own hard-earned labor. The distribution formula will radically change from Author - Agent - Publisher - Printer - Distributor - Retailer - Consumer to a more simplified and direct Author (Sender) - Interactive Participant (Receiver)

The emerging wave of Avant-Pop artists now arriving on the scene find themselves caught in this struggle to rapidly transform our sick, commodity-infested workaday culture into a more sensual, trippy, exotic and networked Avant-Pop experience. One way to achieve this would be by creating and expanding niche communities. Niche communities, many of which already exist through the zine scene, will become, by virtue of the convergent electronic environments, virtual communities. By actively engaging themselves in the continuous exchange and proliferation of collectively-generated electronic publications, individually- designed creative works, manifestos, live on-line readings, multi- media interactive hypertexts, conferences, etc., Avant-Pop artists and the alternative networks they are part of will eat away at the conventional relics of a bygone era where the individual artist- author creates their beautifully-crafted, original works of art to be consumed primarily by the elitist art-world and their business- cronies who pass judgement on what is appropriate and what is not.

something else is starting to take hold in the cultural imagination

My dream is to have people inspired to make webpages again about whatever they'd like, and share them in ways that don't promote competitive, addictive 'engagement stats'. And to have cyber-regional zine libraries that are collecting and supporting different scenes' work

to visit a dat site, much like reading a zine, requires that you ask for it from the creator of it (or be a part of a culture that is supporting and sharing them)

There is no implicit way to discover dat sites--instead you have to share your link with friends and hope they support, seed, and share the link too. A dat site spreads, then, through classic, social and 'underground' channels

Work with what you have, to support the people around you and together you'll create a community that has a defined shape and form only in hindsight. Instead of worrying about having enough onboarding ramps, I say we make a future space that is so exciting, so fun, that is such a cool party with lights so bright that everyone wants to build their own methods to get here and join in. And I thought: what's the coolest, most party thing in the world? Reading.

The future I want is decentralized, consensual, anarchist, feminist, and cool

Salesforce was the first major internet company that exclusively leased data center space to adopt a 100 percent renewable energy commitment in 2013. Salesforce has multiple data center leases in Data Center Alley, totaling 46 megawatts, including a massive new lease with QTS in its new Manassas data center.[

But despite recent creative claims of being “100 Percent Renewable Globally” from surplus supply of renewable credits in other markets,[66] Google has not yet taken steps to add renewable energy to meet the demand of its data centers in Virginia

In 2018, five major IT brands with long-term commitments to renewable energy[52] and who operate data centers or have significant colocation leases in Virginia sent a letter to the Virginia State Corporation Commision (SCC) asking that they not be used by Dominion to justify new fossil fuel growth, asking instead for a greater supply of renewable energy.[53] The SCC ultimately rejected Dominion’s Integrated Resource Plan for the first time in December 2018, providing an important opportunity for additional large corporate customers to tell regulators they need a greater supply of renewables, not more investment in fossil fuel generation assets or pipelines like the ACP.[54]

The rapid deployment of renewable energy and the stagnation of mandatory renewable energy targets in many states has created a large surplus of “naked” or unbundled renewable credits available at the national level for purchase by the voluntary market, driving their price to record lows, less than $1/megawatt hour.

AWS customers seeking to immediately reduce carbon emissions related to their cloud hosting could request to be hosted in Amazon’s California cloud, which is connected to a grid that is 50[33] to 70[34] percent powered by clean sources of electricity

Dominion’s projected demand for the pipeline ignores the fact that six of its 20 largest customers, five of which are data center operators, have made commitments to run on 100 percent renewable energy.[

However, neither of these options improves the energy mix of Virginia or influences future direction and is therefore not ideal for those companies concerned with meaningfully reducing their operational carbon emissions. Of the 15 companies measured in this report, only Apple has invested in enough renewable energy procurement to match its demand in the region

Company Scorecard

If Amazon and other internet companies continue their rapid expansion of data centers in Virginia, but allow Dominion to continue with its strategy to use rising data center demand to justify significant new investment in fossil fuel infrastructure, they will be responsible for driving a massive new investment in fossil fuels that the planet cannot afford.

Dominion Energy, Virginia’s largest electricity provider and the primary electric utility for Data Center Alley, has strongly resisted any meaningful transition to renewable sources of electricity, currently representing only 4 percent of its generation mix, with plans to increase to only slightly over 10 percent by 2030.[1]

pite the coal-friendly policies of the central government. A study showed that Australia is currently installing 250 watts of PV or wind for each inhabitant per year. The EU and US are about one fifth of this. If this rate of growth continues, Australia will reach 50% renewables by 2024 and 100% of electricity demand by 2032. Costs of new large scale PV and wind are now around US35/MWh, lower than the running costs of older coal stations.

Williams and Tang (2013)8performed a rigorous and detailed energy consumption analysis of three cloud-based office productivity applications. They analyzed the power consumption ofthe data center, network, and user devices that access the cloud service. The study also performed an energy consumption analysis on “traditional” noncloud versions of the software to understand the overall impact of cloud services.

Average power consumption can be estimated from single points, although this results in increasing uncertainty. Manufacturers publish the maximum measured electricity (MME)value, which is the maximum observed power consumption by a server model. The MME can often be calculated with online tools, which may allow the specification of individual components for a particular server configuration. Based on these estimations of maximum power consumption, the average power consumption is commonly assumed to be 60 percent of MME for high-end servers and 40 percent for volume and mid-range servers.

In most cases, the “embodied emissions” (all stages excluding the use stage) of software are not significant compared with the overall emissions of the ICT system, particularly when the embodied emissions caused by development of the software are amortized over a large number of copies. In these cases, it is not necessary to carry out a detailed life cycle assessment of the software as part of a wider system. An exception is where bespoke software has very high emissions associated with its development, and these emissions are all allocated to a small number of software copies.

Currently, input-output(IO)tables are published every five years, a long time in IT product evolution. Consequently, EEIO is good at representing basic commodities / materials industries like plastics or metals manufacturing, but not high-tech industries like microprocessors and fiber optic lasers manufacturing.

Calculating cradle-to-gate GHG emissions of IH by the component characterization method

EEIO tables are updated infrequently thus may not be up to date with ICT’s newest technologies and materials. EEIO tables have limited resolution at the aggregate sector level.

rapidly with the onset of innovations, but lag in being included in EEIO databases available to the practitioner. More detail on EEIO data is provided in the calculation sections below

It is interesting to note that the figures from GSMA and GeSI show that energy intensity per gigabyte is improving at about 24% per year for mobile networks, and at about 22% per year for fixed line networks.(The study by Aslan et al calculates a figure of 50% reduction in energy intensity every two years for fixed line networks, equivalent to 29% reduction per year).Also the data shows that the energy intensity per gigabyte for mobile networks is about 50 times that for fixed line networks.

Assuming that the reduction in energy efficiency can be fitted to an exponentially decreasing curve (i.e. because it is more and more difficult to achieve the same reductions), then the data points can be extrapolated to give energy intensity factors for 2015 of 0.15 for fixed linenetworks, and 6.5 for mobile networks, with both factors measured in kWh/GB (kilowatt-hours per gigabyte).

A simple energy intensity factor for the use of the internet would make calculating the emissions resulting from ICT simpler and more widely accessible. Whilst this has been attempted in the past, resulting estimates show huge disparities. Coroama and Hilty6review 10 studies that have attempted to estimate the average energy intensity of the internet where estimates varied from 0.0064 kWh/GB to 136 kWh/GB, a difference factor of more than 20,000.

Typically, for cloud and data center services the largest impacts are from the use stage emissions of the data center and the end user devices.

Simplified parameters for allocation of data center emissions include

Optional processes that are not attributable to the GHG impact of cloud and data center services are:

The end-of-life stage typically represents only -0.5 to -2 percent of a service’s total GHG emissions. This is because of the high level of recycling of network equipment.

For global average electricity emission factors across 63 countries where the points of presence were located, data from the Carbon Trust Footprint Expert Database was used.

Operational activities and non-ICT support equipment covers people (labor)-activities and non-ICT support equipment and activities that are directly engaged and dedicated to the service being assessed.

For example, these measurements might involve running a series of traffic traces16over a period of time to build up statistics on network parameters. The measurements also need to include the energy consumption for the network’s ancillary equipment such as cooling, power conditioning, and back-up power. If this latter data is not attainable, then techniques described in Section 2.8.2“Calculating GHG emissions for the customer domain use stage,” (TPCF and PUE factors), can be used to provide an estimated value for this equipment.

Equipment manufacturers may have estimates of TPCFs for their equipment based on defined operating conditions. In all cases, if a TPCF approach is selected, then the basis for selecting the factor should be fullynoted and documented in the GHG inventory report

Allocation of emissions among independent products that share the same process: for example, multiple products sharing the same transport process (vehicle); multiple telecommunication services sharing the same network; multiple cloud services (email, data storage, database applications) sharing the same data center

A “screening assessment” is an initial assessment of a product to understand its significant and relevant sources of emissions. This assessment is described in the Product Standard in section 8.3.3.

This chapter provides software developers and architects guidance to benchmark and report the GHG emissions from software use in a consistent manner and make informed choices to reduce greenhouse gas emissions. The chapter is in two parts. Part A provides guidance on the full life cycle assessment of software, while Part B relates specifically to the energy use of software, and covers the three categories of software: operating systems (OS), applications, and virtualization.

2015 GeSI published the SMARTer 20308report, extending the analysis out to 2030. This study predicted that the global emissions of the ICT sector will be 1.25 Gt CO2e in 2030 (or 1.97% of global emissions), and emissions avoided through the use of ICT will be 12 Gt CO2e,which is nearly 10 times higher than ICT’s own emissions.

the total abatement potential from ICT solutions by 2020 is seven times its own emissions.

Rebound Effects

The Product Standard (sections 11.2 and 11.3.2) states that“avoided emissions shall not be deducted from the product’s total inventory results, but may be reported separately.”

The Product Standarddefines products to be both goods and services, thus for the ICT sector it covers both physical ICT equipment and delivered ICT services. This Sector Guidance, however, focuses more on the assessment of ICT services. In this Sector Guidance the definition of products includes both networks and software as ICT services.

As the chief executive of the world’s biggest cement company observed, “we know how to make very low carbon cement – by why would we? There is no incentive.”

In the growing trade war between China and the US, it seems the world is unwilling even to think about the entirely legitimate use of consumption-based or border carbon pricing either to encourage cleaner production in China, or to deter the Trump administration from using discriminatory trade measures to re-industrialize drawing partly on older and more carbon-intensive technologies.

The European utilities that tried to ignore the energy transition are now economic zombies; some split their companies in two to try and isolate the assets that have already turned into liabilities in a decarbonizing system.

Averaged over the full 35 years, a constant percentage reduction would require c = - 10%/yr to reach the same end-point – almost impossible at the starting point, but entirely feasible and easily observed in the latter stages of sunset industries.

their analysis leads both teams to the – only slightly caveated - conclusion that the emission reductions required to the deliver the Paris Aims (“well below 2 deg.C”) are implausible, by almost any standard of macroeconomic evidence – and still more so for the most ambitious “1.5 deg.C” end of the spectrum.

Digitalization and Energy 2017

Today, we all use many parts of Engelbart’s prescient vision from fifty years ago – while some of the more profound parts remain still unrealized.

We need to learn to see the cumulative impact of a multitude of efforts, while simultaneously keeping all those efforts visible on their own. There exist so many initiatives I think that are great examples of how distributed digitalisation leads to transformation, but they are largely invisible outside their own context, and also not widely networked and connected enough to reach their own full potential. They are valuable on their own, but would be even more valuable to themselves and others when federated, but the federation part is mostly missing. We need to find a better way to see the big picture, while also seeing all pixels it consists of. A macroscope, a distributed digital transformation macroscope.

If it is not it will become more and more useless in practice over time, however much it remains theoretically correct, not because it has bugs or security holes as such but because the environment it was designed to work in no longer exists and thus the assumptions it was built on are now incorrect.
