Greenhouses are structures designed to retain heat.
The heat-trapping ability of a greenhouse is influenced by a number of factors including the transparency of the greenhouse cover, colour of the surfaces inside the greenhouse, and type of surfaces inside.
By Greenhouse Gases
The earth's "greenhouse effect" is what makes this planet suitable for life as we know it.
Air-quality respiratory illnesses
Change in forest composition
Shift geographic range of forests
Forest health and productivity
Changes in water supply
Increased competition for water
Sea Level Rise
Erosion of beaches
Inundation of coastal lands
Costs to protect coastal communities
Species and Natural Areas
Shift in ecological zones
Loss of habitat and species
Loss of coastal infrastructure: roads, utilities, residential and tourist accommodation, social services, etc.
Higher Water Levels + Higher Wave Amplitude = Increased Wave Energy
Recent coastal vulnerability assessments for Barbados, Guyana and Grenada clearly demonstrate that elevated sea level amplifies the rate of coastal erosion.
In Trinidad some beaches are retreating by as much as 2.0 m yr-1, where sea level has been rising at rate of 8-10 mm yr-1, during the past 15 years.
1. 1:50 year event, i.e. a category 3 hurricane.
2. Passage coincides with high tide and centre passes directly over island.
Initial projection showed that under the above scenario, uprush from a 2- metre wave would travel at least 80-100 m inland.
Even small increases in relative sea level will have a disproportionate effect on flood levels.
By 2080, numbers facing severe floods in the Caribbean, Indian and Pacific Ocean regions would be 200 times higher than if there were no SLR.
Cuba: 98 coastal settlements with a total population exceeding 50 000 persons, which would be completely inundated by a 1.0 m rise in sea-level.
Human Health & Well-being
►Caribbean countries, as elsewhere, exposed to various climate-sensitive diseases - vector and non-vector-borne, e.g. dengue, malaria, yellow fever.
►Short- and long-term threats to human health:
◘ Hurricanes (death and injury; increased sanitation and hygiene risks); ◘ Storm surges (physical injury);
◘ Flooding (drowning; creation of conditions conducive to breeding of insects and other vectors);
◘ Drought (water scarcity; reduced agricultural and food production – risk of malnutrition) .
