The document discusses how climate change poses an existential threat and that mitigation efforts alone will not be enough to address the problem. It argues that internet and information technology will need to help societies adapt to the unavoidable impacts of climate change through the development of renewable energy powered networks and applications that can survive increasing droughts, floods and other disruptions. Specifically, it envisions national research and education networks being built to follow available wind and solar power through technologies like cloud computing in order to maintain critical services as traditional energy infrastructure is compromised by climate change.

Theme of this talkWe have already lost the battle to fight global warmingThe planet is already committed to a 2C temperature rise and rate of CO2 emissions are increasingRather than focusing on reducing CO2 emissions through energy efficiency, smart grids, smart building, etc (Mitigation) we now need to focus on surviving climate change (Adaptation)How can Internet and IT help us build NRENs and support science that can survive global warming?

- 31. Urgency of Action“We’re uncertain about the magnitude of climate change, which is inevitable, because we’re talking about reaching levels of carbon dioxide in the atmosphere not seen in millions of years. You might think that this uncertainty weakens the case for action, but it actually strengthens it. This risk of catastrophe, rather than the details of cost-benefit calculations, makes the most powerful case for strong climate policy. Current projections of global warming in the absence of action are just too close to the kinds of numbers associated with doomsday scenarios. It would be irresponsible — it’s tempting to say criminally irresponsible — not to step back from what could all too easily turn out to be the edge of a cliff.”Nobel Laureate Paul Krugmanhttp://www.nytimes.com/2010/04/11/magazine/11Economy-t.html?pagewanted=1

- 38. The Falsehood of Energy EfficiencyMost 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 environmentGreenpeace 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.pdfBut greater efficiency can paradoxically increase energy consumption by reducing overall cost service and therefore stimulates demandKhazzoom-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

Final remarksThe problem we face is NOT energy consumption, but carbon emissionsThink carbon, not energyWe must start addressing climate change now – not in 2050 or 202080% reduction in CO2 emissions will fundamentally change everything we do including universities and networksHuge potential for innovation and new business opportunities for green communications enabled applications because 30% of energy must come from renewable sources

Editor's Notes
- #28: Building a zero carbon ICT infrastructurePurchasing green power locally is expensive with significant transmission line lossesDemand for green power within cities expected to grow dramaticallyICT facilities DON’T NEED TO BE LOCATED IN CITIES-Cooling also a major problem in citiesBut 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 siteICT is only industry ideally suited to relocate to renewable energy sites Also ideal for business continuity in event of climate catastrophe
