• Introduction
• Phenomenon of global warming:
1.Earth goes through a cycle of warming and cooling (Process of warming).
2. Pre-industrial era saw a balance of this cycle.
3. Industrial revolution followed by massive industrialization, over reliance on hydro-carbons, influx of greenhouse gasses as a result average global temperature started to increase. (Heat trapped by ghgs).
• (Threats) A. Implications for the natural systems
Rise in global average temperature resulting in:
1.Melting of ice caps (polar/glaciers)
2.Increse in sea level
3. Influx of cool water in seas, disruption of thermohaline(oceanic currents)
4. Abnormal weather events (Disruption in monsoon, rain patterns, LA NINA, EL NINO)
5. Drought ,depletion of water resources, ground water resources.
6. Changes in the chemistry of soil, moisture, ph value (perma frost etc).
7. Process of desertification.
8.ozone depletion
9.bio diversity.
• Social Implications(Threats)
Global warming acting as a root cause / catalyst for global turmoil.
1. Food insecurity(reasons mentioned above, examples quoted Darfur , south sudan,other).
2. Malnutrition
3. Spread of diseases (water Bourne diseases)
4. Spread of poverty , third world with weak economies , huge populations finding it difficult to deal with these crisis.
5. Mass migrations, (reasons mentioned above)(refugee, Tdps etc)(examples )
6.Pressure on urban areas, rise of slums
7.Human rights - marginalized segments getting exploited, spike in criminal activities,lack of jobs, non state actors , violence,terrorism.
8.Demographic change leading to violence(populist movements in europe)
9.Wars ,rising tensions(water war ,indo pak, Egypt ethopia sudan,turk,Iraq ,iran, Jordan Israel ets).
10.Economic impact(dilemma for poor nations who are facing the full brunt of global warming even though their share of emissions are negligible compared to developed world).

• Slow response :World has been slow to realize about the magnanimity of the issue owing to the fact that:
1. Changes due to global warming are intangible, human psychology – threats that are tangible such as terrorism get amplified , traditionally get more importance.(example of a case study conducted by PEW research was given).
2. Recent natural disasters a change in thinking was observed

• Great Awakening (Ways to counter it)
1. Global level initiatives.
a.UN led initiatives
Rio summit(including others)

Different accords copen hagen ,Kyoto ,bonn , paris (long list,I have forgotten the order ), carbon ratings , emission quota etc ,
MDG,SDG

2. State level initiatives.
Legislations,public-private partnerships
Renewable energy
Tax rebates
Conservation efforts
Shift in economic structure , right now consumerism which aids in warming(book reference)
Recycling
Public transport
Awareness campaigns
3. Individual level
Changing life style
Habbits
Preferences
4. Role of industry
5. Role of media
6. Research and development
Latest technologies/trends:
Eg(combined cycle plants, plasma reactors etc)
• Conclusion
various examples were quoted.(ipcc reports, country profile etc. Unfortunately I am finding it hard to recall them.)
