
Australia's 5 million Catholics are as morally
bound to combat the loss of biodiversity as they
are to protect the rights of the unborn child.

Rapid climate change as the result of human
activity is now recognised by the global
scientific community as a reality.

People around the world are experiencing the
impacts of increasing land temperatures, rising
sea levels, and a change in the frequency of
extreme climatic events.
Australian Catholic Bishops 2005


The chemical composition of the atmosphere
cloaking our Earth is being changed by pollution
caused by human activity. The resultant
chemical substances strengthen what is called
the greenhouse effect.
As a result, Earth's climatic patterns are being
altered at a pace not experienced in at least
10,000 years.
Atmospheric conditions are now outside the
envelope they have occupied for the last 400,000
years.
It is entirely feasible that in 100 years time
Earth’s climate will be more like it was 20 million
years ago.

Tim Flannery: The Australian: “Climate calamity
forecast by end of century”
 By the end of the century, temperatures will have risen
by 3 degrees
 The cause: our use of fossil fuels
 Australia burns more fossil fuel per capita and exports
more coal than any other nation
 50% of CO2 emissions come from cars.
 3 degree rise: the loss of world heritage areas and
coral reefs and our cities under increasing water
stress. The Murray could dry up, and seas could rise
by up to 6 metres
 2 degree rise: loss of places like Kakadu and our
mountain rain forests, with their fauna; the extinction
of the polar ecosystems

1992: Governments, including Australia, signed UN
Framework Convention on Climate Change
Under this convention, research of hundreds of
scientists from many countries assembled in
Intergovernmental Panel on Climate Change
Its 4th report is due in 2006. Its 3rd report (2001),
states: “there is new and stronger evidence that
most of the warming observed over the last 50 years
is attributable to human activities”
Human activities will continue to change

Rapid Climate Change Impacts on Sea Level
Human-forced rapid climate change is real and is happening. The
planet is and will continue to get warmer and global climate systems
will change rapidly over the coming years, decades and centuries.
There is scientific uncertainty about whether the planet will overall
get wetter or drier, which regions will get wetter or drier, and when
these changes will occur.
There is less scientific uncertainty about changes in sea level:
Thermal expansion of water
Ice melt

New research is emerging every week…

South America’s Glaciers

Now melting glaciers are of concern for millions of
people in South America.
 If the Andean glaciers continue to melt at the current
pace, it will have a severe impact on fresh water
supplies.
 The expected water shortages are also threatening food
supplies across Colombia, Peru, Chile, Venezuela,
Ecuador, Argentina and Bolivia.
 The findings are contained in a report called Up in
smoke, compiled by a coalition of 20 non-government
organisations.

Orange area = melt-zone
Why will sea levels increase?
Thermal expansion of ocean water due to:
An increase in average global temperature, and the transferring of thermal
energy from the atmosphere to the oceans thereby warming the ocean
waters. As water warms, its volume expands.
Changes in how energy is distributed between atmosphere and oceans and
between oceans.
Ice cap and glacier melt
Melting ice will only cause a sea level rise when the ice melts from land.
Thus,the arctic ice cap melting will not cause an increase in sea levels.
But, Greenland melting will:

What does this mean for people?
Low lying coastal countries vulnerable
Low-lying coastal countries are threatened by rising sea level. A one meter
rise in sea level would:
Inundate half of Bangladesh's rice land. Bangladeshis would be forced to
migrate by the millions.
Other rice growing lowlands which would be flooded include those of
Viet Nam, China, India and Thailand. Millions of climate refugees could be
created by sea level rise in the Philippines and Indonesia.
In Egypt, a 1m sea level rise will affect 6 million people with 12-15% of
agricultural land lost,
Around 72 million in China are estimated to be affected by a 1m rise.
We have an appropriate international policy instrument: United
Nations Framework Convention on Climate Change
“The ultimate objective of this convention and any related legal
instruments …is to achieve…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 with a
timeframe sufficient to…ensure that food production is not
threatened and to enable economic development to proceed in a
sustainable manner.”
“The developed country parties commit themselves specifically… [to]
adopt national policies and take corresponding measures on
the mitigation of climate change, by limiting its anthropogenic
emissions of greenhouse gases and protecting and enhancing its
greenhouse gas sinks and reservoirs. These policies and measures
will demonstrate that developed countries are taking the lead
in modifying longer term-term trends in anthropogenic emissions
with the objective of the Convention…”
“…

The Parties should protect the climate system for the benefit of
present and future generations of humankind, on the basis of
equity and in accordance with their common but differentiated
responsibilities and respective capabilities. Accordingly, the developed
country parties should take the lead role in combating climate change
and the adverse effects thereof.”

“The parties should take precautionary measures to anticipate,
prevent or minimize the causes of climate change and mitigate its
adverse effects. Where there are threats of serious or irreversible
damage. Lack of full scientific certainty should not be used as a
reason for postponing such measures…”

A challenge for all Australians
Ultimately we have no choice. The longer we wait to respond, the
more the world’s vulnerable will suffer, and the more costly will be
the solutions.
Australia’s governments need to develop and promote policies and
programmes that will dramatically reduce our emissions of
greenhouse gases.
The Australian government and people should adopt a
“good neighbour” approach and begin now to help our
friends in the Oceania region who are suffering and will
continue to suffer from sea level rises and other
consequences of rapid global climate change.


Kerry Emanuel has recently reported a striking inter-annual
correlation between the destructive power of storms and sea-surface
temperatures, after calculating the total potential destructive power
over the life of storms each year since about 1950. The annual total
energy dissipated by tropical cyclones over the past 30 years in the
North Atlantic has approximately doubled, and this has primarily
reflected an increase in the intensity, not frequency, of cyclones.
This accords with basic atmospheric physics: heat is energy, and as
the sea surface warms, so the developing cyclones acquire more
energy.

 Some recent changes in ID patterns may
reflect influence of climate change:

Tick-borne encephalitis (Sweden)
Cholera in Bangladesh
Malaria in east African highlands
Time-trends in food-borne (infectious) disease
Climate Change and the
Global Burden of Disease
WHO World Health Report 2002 estimated
that, in 2000, global climate change was
already responsible, in developing countries,
for:

2.4% of diarrhoeal disease
 Up to 6-7% of malaria and dengue in specified
groups of high-risk countries
 Substantial declines in regional food yields
(and, therefore, levels of malnutrition)
The Health of the Planet

The Gaia hypothesis,
scientifically referred to as earth
system science, is a class of
scientific models of the geobiosphere in which life as a whole
fosters and maintains suitable
conditions for itself by helping to
create an environment on Earth
suitable for its continuity.

· 137 species are estimated to go extinct each day
· 50,000 species are estimated to go extinct each year
· 78 species were on the original U.S. endangered species list
· 1,201 species were on the U.S. endangered species list as of
October 1999
· 43 percent of endangered and threatened animals in the U.S.
depend on wetlands
· 40 percent of all modern medicines are either modelled on or
synthesized from natural compounds derived from various species
· 95 percent of known plant species have yet to be screened for
their medicinal values
· 30 million species of plants and animals -- more than half of all life
forms on our planet -- live in rainforests
Conclusion
Climate change is not just one more environmental
problem and incidental health hazard.
CC will disrupt various natural systems that affect
human health: regional food production, constraints on
infectious agents, patterns of heat stress, exposure to
extreme weather events (cyclones, floods, fires, etc.).
Primary reason for concern is that, increasingly, CC
will endanger healthy life and, for many, survival.
Awareness of risks to health should galvanise our
commitment to seeking sustainability.


It raises serious moral and spiritual questions,
not just for Catholics but for all Australian
citizens and leaders, and calls for change in our
way of life.6
 Several times we have addressed environmental
issues and recently called for ecological
conversion.8 We now urge Catholics as an
essential part of their faith commitment to
respond with sound judgements and resolute
action to the reality of climate change.



We are intimately interconnected with the whole lifesystem of the planet and the complex interaction
between living creatures and the atmosphere, the land
and the water systems.
We need to keep in mind the Precautionary Principle:
Where there are threats of serious or irreversible
damage, lack of full scientific certainty should not be
used as a reason for postponing remedial measures.
Its application in science, law and politics is a
minimal requirement if wisdom and prudence are our
values.17

We now face an unavoidable rapid change in
global climate and all the consequences that
will bring. If we act now the changes can be
slowed and ultimately halted and harm can
still be minimised.

Restraint, penance and self-imposed
limitations are part of authentic human living
and are in the tradition of choosing sacrifice
for the greater good.

Consumers send powerful signals to the market by
their greenhouse-friendly choice of goods and
services. We dream of a fuller view of humanity,
greater than a mere owning of more material goods.

As one of the world’s biggest emitters, per capita, of
greenhouse gases, Australians have a particular
duty to recognise the fact that they are directly
implicated in the causes of atmospheric pollution
which is harming the many innocent peoples of the
Pacific region. Ironically, the ecological footprint of
the victims is considerably lighter than our own.
That’s all,
folks

depleted; endless slices available – i.e., the way that too
many of us still view the world.

We hear the call of the Earth.
We believe that caring for life on Earth is a spiritual commitment.
People and other species have the right to life unthreatened by
human greed and destructiveness.
Pollution, particularly from the energy-intensive wealthy
industrialised countries, is warming the atmosphere. A warmer
atmosphere is leading to major climate changes. The poor and
vulnerable in the world and future generations will suffer the most.
We commit ourselves to help reduce the threat of climate change
through actions in our own lives, pressure on governments and
industries and standing in solidarity with those most affected by
climate change.
We pray for spiritual support in responding to the call of the Earth.
