Winston Churchill (1874 – 1965):
The era of procrastination, of half-measures, of soothing and baffling expedients, of delays, is coming to a close.
In its place we are entering a period of consequences.
Implications of Global Climate Change
- Soft power and north-south tensions will increase
- Migration and immigration will rise, producing a strong backlash
- Public health problems will grow
- Resource conflicts and vulnerabilities will intensify
- Nuclear activity will increase, with attendant risks
- Challenges to global governance will multiply
- Domestic political repercussions and state failure will occur
- The balance of power will shift in unpredictable ways
- China’s role will be critical
- The United States must come to terms with climate change
Environmental and National Security Implications of Three Climate Scenarios
Assumptions
Expected (2010-40)
- Average 1.3°C warming
- 0.23 meters of sea level rise
- Approximately 30 year time frame
Severe (2010-40)
- Average 2.6°C warming
- 0.52 meters of sea level rise
- Approximately 30 year time frame
Catastrophic (2040-2100)
- Average 5.6°C warming
- 2.0 meters of sea level rise
- Approximately 100 year time frame
Environmental Stresses
Expected (2010-40)
- Water scarcity affects up to 1.7 billion people
- Changed distribution of some infectious disease vectors and allergenic pollen species
- Up to 3 million additional people at risk of flooding
- Up to 30 million more people at risk of hunger due to crop failure
Severe (2010-40)
- Water scarcity affects up to 2 billion people
- Increased burden from malnutrition, diarrheal, cardio-respiratory and infectious diseases
- Up to 15 million additional people at risk of flooding
- Changes in marine and ecosystems due to weakening of the meridional overturning circulation
Catastrophic (2040-2100)
- Water scarcity affects 3.2 billion people
- Increased morbidity and mortality from heat waves, floods, and droughts
- Approximately 30% loss of coastal wetlands
- Up to 120 million more people at risk of hunger due to crop failure
- Possible collapse of the meridional overturning circulation
Security Implications
Expected (2010-40)
- Conflict over resources due to and driving human migration
- Immigrants — or even simply visitors — from a country in which there has been a significant disease outbreak may not be welcomed and could be subject to quarantine and lead to loss of national income from restricted tourism
- Dissatisfaction with state governments could radicalize internal politics and create new safe havens [for violent extremists] in weak and failing states
- A strengthened geopolitical hand for natural gas exporting countries and, potentially, biofuel exporting countries …
[A] weakened hand, both strategically and economically, for importers of all fuel types - Social services will become increased burden on central government where available
- The regional positions of Turkey and others will likely be strengthened as a result of the water crisis
Severe (2010-40)
- Wealthiest members of society pull away from the rest of the population, undermining morale and viability of democratic governance
- Global fish stocks may crash, enmeshing some nations in a struggle over dwindling supplies
- Governments, lacking necessary resources, may privatize water supply …
[Past] experience with this in poor societies suggests likelihood of violent protest and political upheaval - Globalization may end and rapid economic decline may begin, owing to the collapse of financial and production systems that depend on integrated worldwide systems
- Corporations may become increasingly powerful relative to governments as the rich look to private services, engendering a new form of globalization in which transnational business becomes more powerful than states
- Alliance systems and multilateral institutions may collapse — among them, the UN, as the Security Council fractures beyond compromise or repair
Catastrophic (2040-2100)
- Migration toward US borders by millions of hungry and thirsty southern neighbors is likely to dominate US security and humanitarian concerns
- A shrinking Russian population might have substantial difficulty preventing China from asserting control over much of Siberia and the Russian Far East …
[A high] probability of conflict between two destabilized nuclear powers … - Rage at government’s inability to deal with the abrupt and unpredictable crises
- Religious fervor, perhaps even a dramatic rise in millennial end-of-days cults
- Hostility and violence toward migrants and minority groups
- Altruism and generosity would likely be blunted
- US military’s worldwide reach could be reduced substantially by logistics and the demand of missions near our shores
- Electricity generation and distribution highly vulnerable to attack by [violent extremists] and rogue states
