      • _ very likely contributed to sea level rise during the latter half of the 20th century
      • _ likely contributed to changes in wind patterns, affecting extra-tropical storm tracks and temperature patterns
      • _ likely increased temperatures of extreme hot nights, cold nights and cold days
      • _ more likely than not increased risk of heat waves, area affected by drought since the 1970s and frequency of heavy precipitation events.

      • Each degree increase in warming is going to affect the planet and cause dramatic changes
      • Sea level is continuing to rise : 1961-2003 SLR has been rising 50% faster than previous model projections
      • 130million people live below 1m elevation and depend upon the coast
      • There is observed erosion, coastal flooding in many parts of the world – low-lying islands and river deltas
      • Past human damage – such as ecosystem destruction and modification of the coastline exacerbates the impact
      • 500,000 islanders are immediately at risk from Sea Level Rise

      • Changes in rainfall
      • Abnormal tides
      • Extreme sea-surface temperatures
      • Population: 85,000
      • 112 islands (55% low-lying atolls)
      • Majority population on high islands with narrow coastal areas
      • 80% infrastructure within 2 m elevation
      • Observed 1997
      • Torrential rains in the middle of the dry season – USD 6.25 million in losses
      • Extended periods of dry-season causing acute water shortages
      • Increase in propagation of invasive plants
      • Observed 2004
      • Detected an anomaly in predicated and observed high tides
      • Rise in SST led to a corresponding rise in sea-level
      • Caused serious erosion on the islands.
      • Observed 1998
      • Over a period of 1 month, 34-37C was observed on the reef flats
      • 30-90% coral bleached
      • Economic effects on tourism & fisheries
      • Adoption of stronger targets by emitting nations
      • Focus on Adaptation
      • Escape plans !
      • Industrial nations to reduce emissions by 25-40 percent below 1990 levels by 2020.
      • Long-term approach to reduce by 80% emissions by 2050
      • Message
      • There is hope!
      • We need to change the way we do things
      • We need to have access to knowledge, technology and resources
      • Adaptation needs to start today!
      • Defending the Island Home
      • Partnering with MSV Educate Engage Empower Enable
      • Islands need your support
