GLOBAL WARMING THE ECOLOGICAL TIME-BOMB'S
TICKING IS INCREASING

What is climate?
  • Climate is average weather over a period of time
  • Weather is atmospheric conditions over a location
  • Its usually described in temperature, humidity,
    rainfall, wind speed direction, pressure, solar
    radiation
  • Weather changes Why?

3
What causes Weather ?
  • Differential heating of the earths surface
  • Solar radiation Main Driving Force
  • Global Temperature Balance between Incoming and
    Outgoing Radiation
  • As earth adjusts to differential heating, air
    moves causing weather over a location

4
Why does climate vary naturally?
  • Solar Activity
  • Variation in Earths Orbit
  • Volcanic Eruptions
  • Natural Internal Factors
  • Greenhouse Gases
  • Water Vapour
  • CO2, CH4, N2O, CFCs

Global warming affects ALL
  • No human or ecosystem is immune
  • We ALL contribute in many ways as will be shown
    later
  • ALL are starting to pay the costs which will RISE
    over time
  • Some are MORE culpable should ACT now
  • Within ASEAN, Malaysia is the 3rd Highest per
    capita emission- after Brunei Singapore!

Human Systems
  • Sensitive Systems
  • Water resources
  • Agriculture, forestry, fisheries
  • Human settlements
  • Industry, energy, financial services
  • Vulnerabilities
  • Food and water security
  • Incomes and livelihoods
  • Human health
  • Infrastructure

10
Types of Changes Seen
  • Animals and Plants
  • Range shifts (latitudinal or altitudinal)
  • Abundance changes
  • Change in growing season length
  • Earlier flowering emergence of insects
    migration and egg-laying in birds
  • Morphology shifts (e.g. body egg sizes)
  • Hydrology and Glaciers
  • Glacier shrinkage
  • Permafrost thawing
  • Later freeze earlier break up of river and lake
    ice

11
  • Some Evidence
  • Global mean temperature increased 0.60 between
    1861 and 2000
  • Sea level increased 10 20 cm between 1900 and
    2000
  • Observed changes in physical, ecological and
    socio-economic systems
  • Non-polar glacier retreat
  • Reduction in Artic sea ice extent and thickness
    in summer
  • Increased incidence of coral bleaching
  • Increased economic losses due to extreme weather
    events

12
Reasons for concern Risks to Unique and
Threatened Systems Risks from Extreme Climate
Events Distribution of Impacts Aggregate
Impacts Risks from Future Large-Scale
Discontinuities
  • For small amounts of climate change, benefits are
    projected for some sectors and regions, although
    the majority of people are likely to be adversely
    affected
  • For larger amounts of change, projected benefits
    diminish, projected damages increase, and risks
    associated with large scale discontinuities
    become more important

  • The future
  • Climate change is here to stay
  • For short term, reducing the uncertainties is the
    primary concern.
  • It has significant impacts on eco-system,
    socio-economic, sustainable development and
    national growth
  • Concerted efforts are needed to address climate
    change issues
  • Global efforts such as Convention on Climate
    Change, Kyoto Protocol are some preliminary
    initiatives
  • More needs to be done

17
GLOBAL ATTEMPTS to curb 1979 First World Climate
Conference
1985 IPCC First Assessment Report
1990 Second World Climate Conference
- UNGA Resolution for Earth Summit and
negotiation for Conventions on climate change and
biological diversity
1991 Negotiations began
1992 Earth Summit in Rio endorsed UN FCCC and CBD
1994 Malaysia Became Party
1995 First Conference of Parties in Berlin
1997 Adoption of Kyoto Protocol
18
Objectives of Framework Convention on Climate
Change
To achieve stabilisation of greenhouse gas
concentrations in the atmosphere at a level that
would prevent dangerous anthropogenic
interference with climate system to allow
ecosystems to adapt naturally, to ensure food
production is not threatened and to enable
sustainable development
19
CLIMATE CHANGE is a global threat but submerged
in POLITICS
  • UNFCCC is an intergovernmental agreement- hence
    politics is unavoidable
  • But more so since there is a whole range of
    vested interests at stake
  • Those who believe they will suffer adversely CC
    impacts are pitted against those who are
    considered historically the largest GHG emitters
  • There is a marked North-South divide - OECD vs.
    non-OECD, Annex I vs. non-Annex I
  • Even G77 is divided between OPEC rest, AOSIS vs.
    China, India Brazil

20
THE POLITICAL STAKES
  • Who will dominate who will lose out - very
    often based on perceptions rather than reality
  • The strong have managed to get their way - very
    often undermining equity e.g. USA dictating the
    Convention, the Protocol and now even rejecting
    it- EU Japan have played 2nd 3rd fiddle
  • Seems to be a secret strategy to delay
    implementing actual emission reductions UNTIL
    those from China, India Brazil zoom up - then
    to demand these 3 also must reduce - their
    refusal will be used as an excuse for current
    OECD members not to act - the world can fry!

QUESTIONS to ponder on
  • Why is the USA ignoring CC?
  • What have the OECD nations done to reduce GHG
    emissions?
  • Can the world avoid a 2 degree rise in temp
    within the century?
  • How much longer can we play the BLAME GAME?
  • Can todays youth rise above self-interest?
  • What can be done to move from a carbon to a
    hydrogen economy?

24
NOTHING COMES EASY
  • If we want to help curb global warming, we just
    cannot keep pointing fingers
  • We must ACT - at our personal level, at our jobs,
    within our nation, globally
  • Sustainable development sustainability will
    NOT occur if global warming worsens esp.
    exceeding 2 degree C rise
  • Point out the inequities stop being
    HYPOCRITICAL especially among the multinationals
    the rich!

25
THE G8 FAILED TO DELIVER
  • Bush was strong enough to prevent meaningful
    positions being developed
  • All that seems to come out is a meeting with some
    large developing nations in Nov. to get them to
    curb emissions!
  • Kyoto Protocol is being marginalised, weak as it
    already is!
  • Temperatures are steadily rising weather
    extremes worsening!!!
