Why adaptation is more important than mitigation

  1. 1. Using ICT to “adapt” rather than “mitigate” Global Warming Bill St. Arnaud Bill.st.arnaud@gmail.com Unless otherwise noted all material in this slide deck may be reproduced, modified or distributed without prior permission of the author

  3. 3. How fast can decarbonization occur?• The honest answer no one knows• Historical rates of 1-2% have occurred in developing countries – mostly by outsourcing manufacturing to China• For short periods some countries have achieved rates > 2% e.g. France nuclear program• US need to achieve 17% reduction while maintaining modest economic growth which requires rates of decarbonization of >5% per year – Need to shut down over 20 coal plants per year to meet this target 3
  4. 4. Climate Forecasts• MIT report predicts median temperature forecast of 5.2°C – 11°C increase in Northern Canada & Europe – http://globalchange.mit.edu/pubs/abstract.p hp?publication_id=990 MIT• Last Ice age average global temperature was 5-6°C cooler than today – Most of Canada & Europe was under 2-3 km ice• Nearly 90 per cent of new scientific findings reveal global climate disruption to be worse, and progressing more rapidly, than expected. • http://www.skepticalscience.com/pics/Freud enburg_2010_ASC.pdf
  5. 5. Probability of extreme heat waves the probability of an extreme heat wave has increased enormously… by about 40 times (4000%) in the last 50 years http://www.slideshare.net/Revkin/a-defense- 5 of-jim-hansens-climate-conclusions/download
  6. 6. Future Droughts• Palmer Drought Severity Index,or PDSI.• The most severe drought inrecent history, in the Sahel regionof western Africa in the 1970s, hada PDSI of -3 or -4.• By 2030 Western USA could see-4 to -6. Drought in Texas clearlycaused by global warming:http://goo.gl/QjHRS• By 2100 some parts of the U.S.and Latin America could see -8 to -10 PDSI, while Mediterraneanareas could see drought in the -15 http://www.msnbc.msn.com/id/39741525/ns/us_newor -20 range. s-environment/

  8. 8. New Challenge: Climate Adaptation• Obama’s National Science Advisor John Holdren “Mitigation alone won’t work, because the climate is already changing, we’re already experiencing impacts….A mitigation only strategy would be insanity,”• Equal emphasis given to adaptation – avoiding the unmanageable, and adaptation – managing the unavoidable.”• Obama’s Climate Adaptation Executive Order – http://www.stumbleupon.com/su/1tU8go/www.good.is/post/obama-s-secret-climate-adaptation-plan/
  9. 9. We need to get off the electrical grid• Biggest source of CO2 emissions because of coal plants – even in places that use hydro and wind e.g. Quebec and Denmark• Coal plants will be most likely targets of protestors and governments – If Germany and Switzerland are willing to shut down nuclear plants then someday they will realize coal plants are much worse for health, safety and environmental reasons• A good adaptation strategy can also be a good mitigation strategy• Adaptation strategy means using only distributed renewal resources disconnected from the grids – Will most likely survive severe weather events – Will not be subject to outages when governments are forced to shut down coal plants• But how do you reliable and robust telecommunications and Internet when only sources of power are intermittent and unreliable wind and sun? 9

  11. 11. AMD, HP & Clarkson U GreenCloud•Demonstrate the feasibility of deploying a networkof Performance Optimized Datacenters (PODs),geographically distributed to exploit the availability ofrenewable energy for its operation.• Optimizing the utilization of the available renewablepower for computing by intelligently redistributingcomputational load;•Minimizing losses associated with powertransmission by placing the PODs near the powersource;•Providing energy and design efficiency through theuse of additional passive cooling for the PODs•Use the wind power that is currently stranded, i.e.not-delivered to the grid due to the T&D constraints.
