Ireland’s Climate is changing in line with regional and global
trends…..
…but local patterns are evident. It is essential that Ireland’s
climate observation system is maintained and enhanced to
allow us understand how our climate is changing and how
best to adapt

Prof. Graham Parkes
Dept. of Philosophy
The Politics of Global Warming
The Politics of Climate Change:
Philosophical Perspectives
•
•
•
•
•
1. The Climate
Sciences
2. Climate Scepticism
3. The Promethean
Spirit
4. Engaging China
5. Nature and
Technology
Climate Scepticism
Psycho-social factors: the problem is imperceptible, abstract (far future);
wishful thinking, pre-judgments - social
identity
Economic factors: tackling climate change will restrict growth of GNP
An inconvenient fact:
To stand an 80% chance of preventing a temperature rise of 2ºC
over pre-industrial levels, some 80% of currently owned fossil fuel
reserves will have to be left in the ground -- a loss of some $20
trillion.
•
Political factors: two major obstacles (USA)
•
1. The enormous financial power of the fossil fuel
industries
» to fund think-tanks, lobby Congress, re-elect politicians
•
Carbon-rich nations:
» USA, Russia, China, Australia, Venezuela, Iran, Saudi
Arabia, India, Canada . . .
•
2. The power of the religious Republicans in Congress
» who control the Committee on the Environment, the
Energy Committee, the Science Committee
The Spirit of Prometheus
•
Myth: ‘This never happened, but is always going on.’
•
•
The Titan Prometheus gave us fire stolen from Zeus
and (stolen from other Gods) the techniques of
survival:
•
•
•
•
woodworking, house-building, ship-building,
agriculture, animal husbandry, and mining.
Plato: ‘Prometheus gave humans the survival arts, but
not the political arts.’
Prometheus relieved us of ‘a sense of our death’ and gave us instead ‘blind
hopes’.
The punishment of Prometheus:
Chained to a rock on a mountain-top, his liver is pecked out daily by the eagle
of Zeus.

“Financial Market Assessment of Carbon
Liabilities”
Unburnable Carbon 2013: Wasted capital and stranded assets
•
•
565 – 886 billion tonnes CO2 carbon budget for 20 C scenario (IEA & Carbon Tracker)
2,860 billion tonnes CO2 – Top 200 emitters current fossil fuel reserves (Stern et al.)
•
40-60% of the market value of top 200 oil and gas companies ($4 trillion market
value & $1.5 trillion debt) at risk as carbon liabilities are not recognised by investors
Lord Nicholas Stern
Conclusion: Markets do not believe politicians will enforce carbon targets
•
•
If markets are right => carbon targets not enforced and temperature will increase by over 30 C
If markets are wrong => politicians enforce carbon targets and 40-60% of energy companies’
value will be wiped out
Summary
•
No accounting standard for carbon liabilities
•
CO2 liabilities not disclosed in accounts
•
Difficult for rating agencies to assess impact
•
Expectation of CO2 market fix increasing cost of capital –
April 16, 2013, following EU parliament rejection of CO2
“backloading” plan utilities shares ↓: Eon 5%, RWE 2%
•
Neither equity nor credit markets pricing in CO2 risk
Areas of Knowledge
•
•
•
•
•
•
•
•
•
Finance theory on risk and return, portfolio theory
Valuation using Discounted Cash Flow (DCF), Monte Carlo
Modelling financial returns to renewable investors
Capital Asset Pricing Model (CAPM), Weighted Average Cost
of Capital (WACC), Cost of debt (bond pricing), cost of equity –
calculating asset Betas etc.
Options: Black and Scholes, Margrabe spread options, real
options
Financial statement analysis
Energy market models and electricity price forecasting, SEM,
BETTA
Interconnection / Valuation of Interconnectors
Accounting for carbon liabilities

Wind export to Britain: issues to be
resolved
 ‘Greenwire’ project – Element Power (2.5 GW wind)
 `c. 1000 turbines
 ‘EnergyBridge’ project - Mainstream Renewable
Power (3 GW wind)
 c. 1200 turbines
 … both by 2020!

IBBCEAS
•
Measures the transmission of light intensity through a stable optical
cavity consisting of high reflectance mirrors (R>0.999)
•
•
Allows a significant spectral range to be covered simultaneously
Light sources commercially available, simple, inexpensive and bright
•
IBBCEAS + FT
•
High sensitivity, experimental simplicity
 High spectral resolution
