Global Warming

The term Global Warming commonly refers to the mainly human-caused observed increase in global surface temperatures and its projected continuation, though there were also much earlier periods of global warming.

Global warming is projected to have a number of effects on the oceans.
Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.

Ocean acidification threatens damage to coral reefs, fisheries, protected species, and other natural resources of value to society. Without substantial actions to reduce the rate of global warming, land-based ecosystems are at risk of major ecological shifts, transforming composition and structure.



GreenHouseGas (GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone.
Carbon dioxide has the maximum potential for Global Warming (GWP) of exactly 1 (since it is the baseline unit to which all other greenhouse gases are compared).



Diseases caused by Global Warming are mosquito-borne diseases are probably the greatest threat to humans as they include malaria, elephantiasis, Rift Valley fever, yellow fever, and dengue fever. Studies are showing higher prevalence of these diseases in areas that have experienced extreme flooding and drought.

Unchecked global warming could affect most terrestrial ecoregions. Increasing global temperature means that ecosystems will change; some species are being forced out of their habitats (possibly to extinction) because of changing conditions, while others are flourishing.
