This document discusses how climate change poses an existential threat and how information and communication technologies (ICT) and networks can help societies adapt and survive. Rapid warming is already causing severe impacts like droughts and flooding that will disrupt energy systems and infrastructure. To adapt, networks must be designed to operate on renewable energy sources like wind and solar, even relocating facilities to remote locations with clean power. This represents an opportunity for innovation in areas like follow-the-sun computing across data centers. National research and education networks (NRENs) can act as cloud brokers to facilitate such distributed computing on green infrastructure.
John Holdren on Climate Change Challenge 2018 02-15Vincent Everts
In Nantucket I attended an amazing and scary presentation by John Holdren on Climate Change. John Paul Holdren was the senior advisor to President Barack Obama on science and technology issues through his roles as Assistant to the President for Science and Technology, Director of the White House Office of Science and Technology Policy, and Co-Chair of the President’s Council of Advisors on Science and Technology (PCAST).
Holdren was previously the Teresa and John Heinz Professor of Environmental Policy at the Kennedy School of Government at Harvard University, director of the Science, Technology, and Public Policy Program at the School's Belfer Center for Science and International Affairs, and Director of the Woods Hole Research Center.
Nobel Laureate Mario Molina spoke about the impact of energy on climate change at the Joint Public Advisory Committee's public forum on Greening North America's Energy Economy in Calgary on 24 April 2013. More at: http://cec.org/jpacenergy

Today, CO2 emissions from fossil fuels are around 50 per cent higher than they were 20 years ago, and have been rising each year. This kind of change to the chemical mixture in the air doesn’t come without consequences. Acting like a blanket, the build-up of greenhouse gases is the main reason why the average global temperature has risen by nearly 1°C in the last century. This booklet explains why a rise of only a few degrees in the average global temperature risks our prosperity, security, and health. It explains why it is so important to reverse the rise in emissions within the decade. And why it is still within our means to do so. For more information visit www.climateinstitute.org.au/dangerous-degrees.html
he Energy Internet
An alternative renewable power distribution system to the electrical grid using dynamic charging of autonomous eVehicles and Internet Routing Protocols
Governments around the world are starting to mandate that government funded organizations such as universities and NRENs develop Climate Change Preparedness plans. This is in recognition that we are already committed to a 2C average temperature increase and given the lack of any international agreement on curbing GHG emissions we may be headed to a 6C global average temperature increase. More severe weather patterns are expected which will cause severe disruption to our energy and physical infrastructure. Resilient networks, new network architectures and tools such as distance education and remote collaborative research will be required by our universities and schools to survive and endure periods of such extreme weather. A well designed and thought out Climate Change Preparedness plan can also help higher-ed and NRENs increase their operational resiliency, as well as significantly reduce their current electrical energy costs. In addition a good Climate Change Preparedness plan can also be an excellent way for higher-ed and NRENs to reduce their existing GHG footprint.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

38. The Falsehood of Energy Efficiency Most current approaches to reduce carbon footprint are focused on increased energy efficiency of equipment and processes No question it save money, but does little for the environment Greenpeace Report “Electricity demand of IT remains on the rise, efficiency can only slow emission growth. In order to achieve the reductions necessary to keep the sector’s emissions in check and maintainsafe levels of global greenhouse gases, clean energy needs to become the primary source of power for IT infrastructure. Greenpeace “How dirty is your data”http://www.greenpeace.org/international/Global/international/publications/climate/2011/Cool%20IT/dirty-data-report-greenpeace.pdf But greater efficiency can paradoxically increase energy consumption by reducing overall cost service and therefore stimulates demand Khazzoom-Brookes postulate (aka Jevons paradox - not to be confused with rebound effect) The issue is not the amount of energy that we use, but the type of energy
39. The need to move to clouds powered by wind and sun Campus computing 20-40% electrical energy consumption on most campuses Studies in UK and The Netherlands Closet clusters represent up to 15% of electrical consumption – UBC study Campus data center represents 8-20% of electrical consumption IISD study of Dalhousie, UoAlberta and Ottawa U IISD study demonstrated that moving Canadian research to cloud would pay for itself in energy savings and CO2 reduction Clouds could save universities millions of dollars in energy and support costs http://green-broadband.blogspot.com/2010/12/how-r-networks-can-help-universities.html Millions of dollars being wasted on old clusters and HPC facilities that could be spent on critical research
40. Get off the Grid! Purchasing green power locally is expensive with significant transmission line losses Demand for green power within cities expected to grow dramatically ICT facilities DON’T NEED TO BE LOCATED IN CITIES -Cooling also a major problem in cities But most renewable energy sites are very remote and impractical to connect to electrical grid. Can be easily reached by an optical network Provide independence from electrical utility and high costs in wheeling power Savings in transmission line losses (up to 15%) alone, plus carbon offsets can pay for moving ICT facilities to renewable energy site ICT is only industry ideally suited to relocate to renewable energy sites Also ideal for business continuity in event of climate catastrophe

52. Wireless Challenges on Campus Gap between management and IT staff Maintenance of wireless networks is substantial Wireless access is essential for end-users Wireless infrastructure is regarded as secondary Network planning constantly changing building infrastructure raises coverage challenges and is unpredictable WLAN — scalability, interference, availability Limited or too much coverage (eduroam conflicts) Session continuity and access to campus services whilst moving Wireless Campus Desires Coupling of wireless campus with (private)3G/4G infrastructures “Open SIM” /operator agnostic Guest access to eduroam Traceability and privacy-proof indoor positioning of individuals Easier network planning — coverage outside buildings Outsourcing of network maintenance Less bureaucracy, match finances with plans and stop reinventing the wheel

Impact of 5G networks 37 The PC is out of the loop The phone is a sensor platform Hardware add-on innovation Location based sensing Touch screen UI Processing is done in real time in the cloud Allowing processing that can’t be done on the device Big data analysis Building new networks on the back of existing ones Reinventing a major industry Source: Tim OReilly

56. Final remarks The problem we face is NOT energy consumption, but carbon emissions Think carbon, not energy We must start addressing climate change now – not in 2050 or 2020 80% reduction in CO2 emissions will fundamentally change everything we do including universities and networks Huge potential for innovation and new business opportunities for green communications enabled applications because 30% of energy must come from renewable sources
