Climate Change and Conflict:
How Mediation Can Help Save the Planet

“’We’ and ‘they’ no longer exist. This planet is just us.
The destruction of one area is the destruction of yourself.
That is the new reality.”

Some Predictions of Climate Change
• Disappearance of sea ice
• Greater frequency of temperature extremes, including heat waves and cold
spells
• Increase in tropical cyclone intensity
• Decrease in water supplies in semi-arid areas including the Mediterranean,
western US, Africa and Brazil
• Eventual elimination of the Greenland ice sheet, and resulting rise in sea
level of about 7 meters (about 23 feet), or more
• Minimum of 20 to 30% of species at risk of extinction if average global
warming exceeds 1.5 to 2.5 degrees C
• Heavy rainfall in some areas and drought or far less in others, including the
Monsoon season
• Soil degradation, desertification and shift in grain growing regions
• Increasing acidification of the world’s oceans, leading to a massive die-off
of marine life
• Significant life threats to at least 20% of the world population, or about 2
billion people

 40% of agricultural production comes from irrigated agriculture
 80% of freshwater abstraction is used for irrigation
 Increasing problems with drying out and pollution of rivers and lakes

Dry Lands
• 10-20% of dry lands are subject to degradation
• Dry land populations are among the most ecologically, socially
and politically marginalised populations
Soil Degradation
 Erosion
 Reduction i soil carbon (humus)
 Compaction (especially in subsoil)
 Pollution
 Salinisation
 Desertification
Many of these
processes
are exacerbated by
climate change
Scientific Results and Observations (1)
• Global-average surface temperature increased by about 0.6 ºC
over 20th century
• 1990s warmest decade and 1998 warmest year in last 1000
years in Northern Hemisphere
• Over last 50 years night-time minimum temperatures increased
by about 0.2 ºC per decade
• 10% reduction in snow cover ice since late 1960s
• Reduction of about two weeks in annual duration of lake and
river ice over 20th century
• Widespread retreat of mountain glaciers during 20th century
Scientific Results and Observations (2)
• Northern Hemisphere spring and summer sea-ice extent
decreased by 10-15% since 1950s
• 40% decline in late summer Arctic sea-ice thickness in
recent decades
• Global-average sea level has increased by 10-20 cm during
20th century
• 0.5-1% per decade increase in Northern Hemisphere midlatitude precipitation during 20th century
• 2-4% increase in frequency of heavy precipitation events
in Northern Hemisphere mid- and high-latitudes over latter
half of 20th century
Increases Under All Scenarios
• Global-average surface temperature projected to increase by
1.4 ºC to 5.8 ºC by 2100
• Rate of warming likely unprecedented in at least the last
10,000 years
• Land areas will warm more than the global average
• Global average precipitation will increase over the 21st
century
• Very likely to be more intense precipitation events
• Snow cover and sea-ice projected to decrease further
• Glaciers and icecaps projected to continue widespread
retreat
• Global mean sea-level projected to increase by 9 cm to 88
cm by 2100

How Mediators Can Help Save the Planet (1)

The problems we now face, of which climate change is only one, can
no longer be solved locally, or even by a consortium of the largest
nation-states.
There are no international organizations, including the United Nations,
that are presently capable of solving them.
None of these problems can be solved through force or litigation.
Bitter conflicts and diverse opinions are widespread between nations,
political groups and environmental organizations over whether these
problems actually exist, who is responsible for them, and how to solve
them.
These conflicts are blocking us from reaching agreements, finding
solutions, working preventatively or addressing them in time.
The dispute resolution mechanisms currently in place are incapable of
resolving them quickly or deeply.
If we do not solve them fully and in time, hundreds of millions, perhaps
billions of people will die, thousands of species will become extinct, and
the Earth may become uninhabitable.

These problems will only increase as population and technology grow
and we become more interconnected and interdependent.
The only way we can solve these problems and increase our chances
of surviving is to build our capacity to communicate across differences,
agree on solutions and implement them through voluntary international
collaboration.
To improve our capacity for voluntary collaboration, we need to reduce
the systemic sources of chronic conflict and resistance to change
worldwide.
We therefore need to reduce poverty and inequality, find alternatives to
unregulated market competition, and increase political democracy.
To do any of these successfully, we need to vastly increase skills in
cross-cultural communication, prejudice reduction and bias awareness,
creative informal problem solving, group facilitation, public dialogue,
collaborative negotiation, mediation, conflict resolution systems design,
and similar methods.
To do these, we need an organization that is able to develop, organize,
and channel the energies and skills of mediators world-wide.
“We will have to repent in this generation not merely for the
vitriolic words or actions of the bad people, but for the
appalling silence of the good people. We must come to see
that human progress never rolls in on wheels of inevitability.
It comes through the tireless efforts and persistent work of
men … and without this hard work time itself becomes an
ally of the forces of social stagnation. We must use time
creatively, and forever realize that the time is always ripe to
do right.”
Dr. Martin Luther King, Jr.

Three flags? Nothing. What are we waiting for?”
