2. Global Average Temperature
3. 2009 second warmest year ever
4. Jan, Feb Mar 2010 warmest ever
This is despite a solar sun spot minimum
5. Climate Forecasts
- MIT report predicts median temperature forecast of 5.2C
6. 11C increase in Northern Canada & Europe 7.
http://globalchange.mit.edu/pubs/abstract.php?publication_id=990 8.
Last Ice age average global temperature was 5-6C cooler than today
9. Most of Canada & Europe was under 2-3 km ice 10. With BAU we
are talking about 5-6C change in temperature in the opposite
direction in less than 80 YearsMIT
11. Climate Change is not reversible
Climate Change is not like acid rain, water management or ozone
destruction where environment will quickly return to normal once
source of pollution is removed
GHG emissions will stay in the atmosphere for thousands of years
and continue to accumulate
Planet will continue to warm up even if we drastically reduce
emissions
Weaver et al., GRL (2007)
All we hope to achieve is to slow down the rapid rate of climate
change
12. Climate tipping points
USGS report finds that future climate shifts have been
underestimated and warns of debilitatingabrupt shift in climate
that would be devastating.
Tipping elements in the Earth's climate- National Academies of
Science
Society may be lulled into a false sense of security by smooth
projections of global change. Our synthesis of present knowledge
suggests that a variety of tipping elements could reach their
critical point within this century under anthropogenic climate
change.
13. The Global ICT Carbon Footprint isRoughly the Same as the
Aviation Industry Today
But ICT Emissions are Growing at 6% Annually!
www.smart2020.org
ICT represent8% of global electricity consumption
Projected to grow to as much as 20% of all electrical consumption
in the US(http://uclue.com/index.php?xq=724)
Future Broadband- Internet alone is expected to consume 5% of all
electricity

14. The Global ICT Carbon Footprint by Subsector
The Number of PCs (Desktops and Laptops) Globally is Expected to
Increase from 592 Million in 2002 to More Than Four Billion in
2020
www.smart2020.org
Data Centers& Clouds Are Low Hanging Fruit
PCs Are Biggest Problem
Telecom & Internet fastest growing
15. IT biggest power draw

16. Digital vs Traditional appliances
17. Growth Projections Data Centers
Half of ICT consumption is data centers
In ten years50% of todays Data Centers and major science facilities
in the US will have insufficient power and cooling;*
By 2012, half of all Data Centers will have to relocate or
outsource applications to another facility.*
CO2 emissions from US datacenters greater than all CO2 emissions
from Netherlands or Argentina http://bit.ly/cW6jEY
Coal fuels much of Internet 'cloud,' Greenpeace says
http://bit.ly/bkeSec
Data centers will consume 12% of electricity in the US by 2020 (TV
Telecom)

18. Green IT Enabling Effect is Significant
Can deliver carbon emission reductions five times size of sectors
own footprint by 2020
7.8 Giga-tons carbon dioxide equivalent
Greater than US or Chinas current annual emissions
Key sectors include Transportation, Buildings, Industrial
Processes,and Power
No other sector can achieve this enabler effect !!

19. The Falsehood of Energy Efficiency
Most current approaches to reduce carbon footprint are focused on
increased energy efficiency of equipment and processes
Also 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)
In last Energy crisis in 1973 Congress passed first energy
efficiency laws (CAF) which mandate minimum mileage for cars, home
insulation and appliances
Net effect was to reduce cost of driving car, heating or cooling
home, and electricity required for appliances
Consumer response was to drive further, buy bigger homes and
appliances
The issue is not the amount of energy that we use, but the type of
energy
20. More on Energy Efficiency
If we add all of the potential savings from energy efficiency, they
only abate about25%of GHG emissions.
To make matters worse, the low hanging fruit will grow smaller over
time, decreasing returns to our efforts.
To reduce our GHG emissions by 85 percent by 2050, we need radical
innovation to provide clean energy alternatives, rather than just
using carbon-based fuels a bit more efficiently.
ITIF Institute - Debunking the Myths of Global Climate Change
Offsetting efficiency savings will be more people in the US in the
next decase(391 million vs. 305 million), more households (147
million vs. 113 million), more vehicles (297 million vs. 231
million) and a bigger economy (almost double in size).Obama's

21. Zero Carbon strategy essential
Zero carbon strategy using renewable energy critically important if
governments mandate carbon neutrality, or if there is a climate
catastrophe
With a zero carbon strategy growth in demand for services will not
effectGHG emissions
Anything times zero is always zero
Wind and solar power are most likely candidates because of
opportunity cost/benefit analysis especially time to deploy
Nuclear has high opportunity cost becauseof time to deploy
http://climateprogress.org/2008/12/14/stanford-study-part-1-wind-solar-baseload-easily-beat-nuclear-and-they-all-best-clean-coal/
But renewable energy sites are usually located far from cities and
electrical distribution systems are not designed to carry
load
http://www.americanprogress.org/issues/2008/12/pdf/renewable_transmission.pdf
Local wind/solar will be an important component
22. Grand Challenge Building solutions using renewable energy
only
Most government GHG plans plan to 30-40% of electrical power will
come from renewable sources
How do you provide mission critical services when energy source is
unreliable?
Ebbing wind or setting sun
Back up diesel and batteries are not an option because they are not
zero carbon and power outages can last for days or weeks
Need new energy delivery architectures and business models to
ensure reliable service delivery
R&E networks and clouds can play a critical role
Not so much in energy efficiency, but building smart solutions that
adapt to availability of renewable power
23. MIT to build zero carbon data center in Holyoke MA
The data center will be managed and funded by the four main
partners in the facility: the Massachusetts Institute of
Technology, Cisco Systems, the University of Massachusetts and
EMC.
It will be a high-performance computing environment that will help
expand the research and development capabilities of the companies
and schools in Holyoke

24. Evolving Internet & Impact on GHG
Van Jacobson predicted several years ago evolution away from
end-to-end Internet to information Internet
http://video.google.com/videoplay?docid=-6972678839686672840#
Current Internet is based on old telco architecture of connecting
users
New Internet is based on connecting users to information
Arbor study has vindicated Van Jacobson prediction
C. Labovitz, et al "ATLAS Internet Observatory 2009 Annual Report"
http://www.nanog.org/meetings/nanog47/presentations/Monday/Labovitz_ObserveReport_N47_Mon.pdf
Over 50% of Internet traffic is from handful of information
suppliers such as Google, Akamai, Content Distribution networks
etc
Will have major impact on wireless networks as we move from end to
end cell phone network to cell phone Internet

27. New Internet
Increasingly most connections will be local to nearest IX where
user will connect to cloud, CDN or social network
Connections to another user or computer at the edge of the cloud
will be less common
Network topologies and architectures will be driven by application
and content rather than connecting users end-to-end
Cyber-infrastructure and UCLP were forerunners of these
development
Future wireless networks are likely to also evolve in this
manner
Dont need an end to end network for accessing applications and
content
User white space and wifi to provide data to cell phones
Next network neutrality battleground will be last inch open devices
and last tower -
Much easier to deploy zero carbon Internet
CDN, clouds and social network infrastructure can be built along
GSN model
Users will increasingly use solar powered iPhone, iPad to access
information and applications

28. Grand Challenge Building robust ICT services using renewable
energy only
30% of electrical power will come from renewable sources
How do you provide mission critical ICT services when energy source
is unreliable?
Ebbing wind or setting sun
Back up diesel and batteries are not an option because they are not
zero carbon and power outages can last for days or weeks
Need new network architectures and business models to ensure
reliable service delivery by quickly moving compute jobs and data
sets around the world to sites that have available power
Will require high bandwidth networks and routing architectures to
quickly move jobs and data sets from site to site
