According to Hansen and others:
Earth is out of energy balance
Global warming is somewhere between 0.70.8C
More warming in the pipeline
Highly intensive carbon intensive sources can
push climate science beyond tipping point
Since IPCC AR 4: evidence of urgency
Summer sea ice cover in the artic is
decreasing (2007 and 2001) to an area 40%
less than a few decades earlier
Artic sea ice thickness reduce (faster than
IPCC climate model predicted)
The Greenland and Antarctic ice –shedding
ice at a rate now several hundred cubic Kilo a
year. Mountain glaciers are receding rapidly
all around the world fresh water availability
of major rivers
Projected regional impacts in developing country regions (IPCC AR4, 2007)
Africa and climate change

With current 0.74 C of warming, Africa:
Severe rain
Progressive drying of soils
Threats to food production
Increase in sea surface temperature->Sahel
drought (1980s) & drought in Horn of Africa
(2000s)
Africa and climate change
With increase warming ( 1.5C) by 2050:
Average production losses in African maize,
22%
Yield losses in other crops: sorghum (17%),
millet (17%), groundnut (17%) and cassava
(8%)
Emission reduction is needed to
restore earth energy balance
Science calls for: 350 PPM ( 450 ppm CO2eq
represents upper limit on concentration of
heat-trapping emissions.) Temp. 1, 1.5-2C
A 6%/year decrease of fossil fuel emission
(2013); 15% (2020)
About 100 GT reforestation
Clean energy
Within the context of UNFCCC the need for
reducing global emissions has been
recognized… The convention argues for the
stabilization of the climate system
Shared Vision
Article 2
The Ultimate Objective…is to achieve, in accordance with
the relevant provisions of the Convention, stabilization of
greenhouse gas concentrations in the atmosphere at a
level that would prevent dangerous anthropogenic
interference with the climate system. Such a level
should be achieved within a time frame sufficient to allow
ecosystems to adapt naturally to climate change, to
ensure that food production is not threatened and to
enable economic development to proceed in a
sustainable manner.
Shared Vision…
The Bali Action Plan
1. (a) A shared vision for long-term cooperative action, including a longterm global goal for emission reductions, to achieve the ultimate
objective of the Convention…
1 (b) (i) Measurable, reportable and verifiable nationally appropriate
mitigation commitments or actions, including quantified emission
limitation and reduction objectives, by all developed country Parties,
while ensuring the comparability of efforts among them…
1 (b) (ii) Nationally appropriate mitigation actions by developing country
Parties in the context of sustainable development, supported and
enabled by technology, financing and capacity-building, in a
measurable, reportable and verifiable manner;

In near future Africa will be developing more
rapidly emitting more so implication of Shared
vision is important for Africa—mitigation (low
carbon-methane, finance (now for adaptation,
TT and Capacity building).
Capacity building important for Africa
The equity approach has implications for the
various topics under LCA.
Of the cumulative global emissions Annex I
countries accounted for 72% of the total
compared to their share of population of
about 25%. Developing countries accounted
28% of the total. The overutilization by Annex
I was 568 Gt, the same as the underutilisation by developing countries.
Long term global reduction goals
Long term global emission reduction goal:
a) temperature, 1,1.5, 2 degree C

Global Peaking Year
Global peaking year should also be
discussed in the context of equity and to
be preceded by a paradigm for the equitable
sharing of the atmospheric space or
resource. Like the global goals for
temperature and emissions reduction, global
peaking year have implications for the
responsibilities of developing countries or for
their options in their emissions and thus their
economic pathways.

Observations
As can be expected, the required mitigation
in non-Annex1 a countries is greater:
if the global path peaks earlier.
If Annex 1 reductions are less ambitious.
Conclusions
Maintaining a reasonable chance of keeping
warming below 2°C requires rapid global
reductions.
If peaking is not well before 2020, warming will
not be “likely” to remain below 2°C.
Weak mitigation in Annex 1 countries will imply
dramatic reductions in non-Annex 1 countries,
for any of these global pathways.
Ambitious mitigation in Annex 1 countries (i.e., 40% by 2020) will also imply less dramatic
reductions (by ~5 GtCO2eq in 2020)
…
Conclusion shared vision
Shift from developed countries effort to
developing countires. This will keep
developing countries poor.
So shared vision boils down to a political
discussion it is not simply a scientific
numbers only decision. So cannot have the
numbers until you have a clear understanding
of: Finance, technolgy and capacity building
deliverables in the context of CBDR and
Equity
Bottom line on Shared Vision
Options: give figure say 50% by 2050 and no
context
Give figure and context: AI peaking, $
finance, tech for NAI.
So ultimately there are at least 5 numbers
that must be taken account of not simply 2-3,
as advocate by developed parties:
Global cut, say 50% by 2050
X cut for AI, 80-100%
Implied residual cut for NAI
How much finance and technology for NAI
Possible seven figure:
Equitable Access to sustainable
development & Africa
In the final analysis shared visions is
ultimately about how do you burden sharing
of the remaining carbon space?
Hence the context for the numbers is the
entire BAP and the convention.
EASD
Since Tanjin, the Africa group has been
projecting this strategy. Calling for clear ideas
about adaptation, finance, TT (beyond what
is now in the tech mechanisms; targets);
capacity building in addition to overall
mitigation approach . All of these things
impacts how development takes place now
and into the future.
Since Cancun focus on equitable access to
sustainable development
EASD
EASD is how to divide up the remaining
atmospheric space (how do you divide up the
Long term emissions reducion goal and the
peaking year issues between AI and NAI
(Implies: Carbon budget)
EASD is an integrated approach form long
term emission.

EASD
Issue: numbers first or Context first?
Partners and some developing countries
want to set LTGoal and peak year before all
the others are decided (offering the GCF,
TM/TEC ).
The Africa group and many other developing
countries, including the BASICs would like to
see clear understanding and agreement of all
aspects, including targts, operationalization in
the framework of EASD.
Important link between GNP and emission so
decoupling have strong implication for
development
TT must go beyond trading arrangmetn to
skills building and absorbitve capacity and
development.
Let’s be clear …
The climate negotiations are not an environmental negotiations. These are
essentially negotiations over the development future of developing countries;
over how global economic relationships and national economic futures will be
shaped as a result of addressing and adapting to the inevitable impacts of
climate change
Our countries’ industrialization and development future are at stake.
Africa has a significant role to play in highlighting the economic, trade and
development implications of the possible results from the climate change
negotiations
