The Problem
Anthropromorphic Global Warming. (AGW)
Global warming caused by Humans!
Lots of debate on both sides.
Interpreted Data under attack.
The probable results will be the melting of the ice
sheets in Greenland & Antarctica with associated sea
level rise.
Current Weather patterns could change.
Humanity must reduce levels of Greenhouse Gases
released into the atmosphere soon to prevent or
lessen effects.
“My Lords, the most reliable measurements
we have of CO2 in the atmosphere are
those of the Mauna Loa observatory in
Hawaii. As of February 2011, those showed
levels of CO2 to be still rising. It is up to
391.76 parts per million, compared with
389.85 parts per million last year. Not only
are those rising, they are increasing at an
accelerating rate from decade to decade.
Because, as collective humanity, we are
doing so little to change the situation, it is
now unlikely that we will be able to confine
global warming to an average to two
degrees Celsius-as noble Lords will
remember, the limit that most scientists
regard as reducing risk to reasonably
manageable dimensions.”

Climate Change Quotes
• “On the island where I live, it is possible to throw a
stone from one side to the other. Our fears about
sea-level rise are very real. Our Cabinet has been
exploring the possibility of buying land in a nearby
country in case we become refugees of climate
change”. Teleke Lauti, Minister for the Environment,
Tuvalu.
• “Climate change is the most severe problem we are
facing today, more serious even than the threat of
terrorism” David King, UK Government Chief
Scientific Advisor, Jan 2004.
• “How could I look my grandchildren in the eye and
say I knew about this and did nothing? David
Attenborough, 2006.

The 1st Elephant (Mammoth)
• A massive reduction in grasslands and the spread of forests may have been the primary
cause of the decline of mammals such as the woolly mammoth, woolly rhino and cave
lion, according to Durham University scientists.
• The findings of the new study challenge the theory that human beings were the primary
cause of the extinction of mammals through hunting, competition for land and increased
pressure on habitats.
• The research is part of the most comprehensive study to date of Northern Hemisphere
climate and vegetation during and after the height of the last Ice Age, 21,000 years ago. It
shows that, over a huge part of the Earth’s surface, there was a massive decline in the
productivity and extent of grasslands due to climatic warming and the spread of forests.

What is the challenge?
• The UK Carbon Reduction Targets.
• The Energy Gap.
• Maintaining BAU
BCS Green IT/DCSG Branch
Presentations 2011/12 John Booth
11
Current UK Reduction Target &
Policy Tools
• Net UK Carbon Account 80% of 1990 baseline by 2050
• 1990 baseline 3900 MtCO2e
• Latest Carbon Budget – 2023-2027 set at 1750 MtCO2e (50% Reduction) (8/6/11)
Target = 780MtCO2e
The Tools
• Carbon Reduction Commitment (Energy Efficiency Scheme)
• Large Combustion Plant Directive (LCPD)
• NI 185/186 (LA’s CRC)
• FIT’s (Feed In Tariffs) for renewables
• Growth of Wind (NIMBYism)
• New Nukes (Long Lead Times)
• Infrastructure Smart Grid (for renewables)

The Energy Gap
• Energy Gap
– 8 UK Nuclear PS’s Decommissioned by 2023 (20% of Capacity!)
– Large Combustion Plant Directive Restricts Coal Fired to 7000hours
– UK Energy Planning, Too Little, Too Late
– Black-Outs/Rationing from 2015?
Energy Costs Rise !

Who pays for your IT energy?
Facilities?
You?

Be Prepared!
For MD/CEO/CIO/Finance/ Facilities scrutiny
For radical change
Calculate Energy Costs for IT
Evaluate your CMDB (Asset Register)
Review IT Governance (Green IT Governance)
Review DR & Data Management Policy
Develop Internal Cloud
Think Lean, Think Lean IT
Budget Contraints
Nothing will be off the table when it comes to IT.
