Discussion
• Puerto Rico v.s other Carribean Islands
Outline
Climate change is referring to any long-term change in the climate of the Earth, or the climate of a region or city.
This includes both heating and cooling, change in average precipitation and heavy rain events, sea level rise and other changes.
What is a climate change?
PRCCC,2013
What is a sea level rise?
Sea level, is the height of the sea surface averaged over all stages of the tide over a long period of time (Encyclopædia
Britannica,2015)
Causes of global mean sea level rise
1. Warming the ocean (thermal expansion)
2. Loss of ice by glaciers and ice sheets
3. Reduction of liquid water storage on land
(IPCC,2013)
Regional sea level rise by the end of the 21st century
Global Mean Sea Level Projections
An island is land completely surrounded by water
What is an island?

How the increase in sea level has impacted the coasts of Puerto Rico?
(PRCCC,2013)
Forest- Increase the risk of salt intrusion- Tolerance levels-Increase Mortality
Tourism- Coastal erosion, Loss of beach area, Higher cost to protect and maintain waterfronts and sea defense
Livelihoods- increased can lead to coastal erosion and related damage to structure that can affect livelihoods, increase could results in the loss of coastal habitat that serve as natural barriers
Sea level rise Impacts
(PRCCC,2013)
Sea level rise impacts
Shorebirds and sea birds- starvation during migration stopovers for re-fueling, displacement in to less optimal habitat, potential increased in predation in less optimal habitat, nest abandonment and mortality egg and chicks
Loss of smalls islands (Guayanilla case)
(PRCCC,2013)
Coral Reef
Other Impacts
(PRCCC,2013)
Coastal Zone Impacts
South area of Puerto Rico
Loiza
Control and Mitigation Measures
(Nicholls,2011)
Future impacts of sea level rise
The magnitude of sea level rise
Coastal physicography
The level and manner of coastal development
The success (or failure) of adaptation
(Nicholls,2011)
Discussion
A short, medium and long term Puerto Rico we are prepared to work with this situation? What remains to be done?
As you can compare with other Caribbean islands?
Other recommendations?
