We need a new nuclear plant per day to keep stabilization at 2C

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
Climate Forecasts
MIT
• 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
• 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

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

Future Droughts• Palmer Drought Severity Index, or PDSI.
• The most severe drought in recent history, in the Sahel region of western Africa in the 1970s, had a PDSI of -3 or -4.
• By 2030 Western USA could see -4 to -6. Drought in Texas clearly caused 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 Mediterranean areas could see drought in the -15 or -20 range.

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/

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?

AMD, HP & Clarkson U GreenCloud •Demonstrate the feasibility of deploying a network of Performance Optimized Datacenters (PODs), geographically distributed to exploit the availability of renewable energy for its operation.
• Optimizing the utilization of the available renewable power for computing by intelligently redistributing computational load;
•Minimizing losses associated with power transmission by placing the PODs near the power source;
•Providing energy and design efficiency through the use 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.
