Effects.

Humans.

- Economic impact
- It could help to increase food production (because increasing levels of carbon dioxide may speed up the rate of photosynthesis)
- Leads to more health concerns (disease vectors could change their geographical patterns and breeding seasons because of change in temperatures. eg. tropical diseases could be more common in temperature regions)
- Health effect directly from the heat
- Effects on Aquatic system (ecosystems)
- People move inland, increasing the populations' density and leading to an increase in hunger and disease

Environment. - Polar ice caps and mountains glaciers to melt rapidly - Increase in the salinity of freshwater - Coastal lands washed under the ocean - More tidal waves, flood and strong beach erosion in the coastal areas

Ecology. - Changes in the enviroment could possibly force various species of flora and fauna out of their natural habitats. - Possible mass extinctions due to lost of habitats.

Climate.

- Changes in weather patterns
- Possible increase in flooding due to increase in rainfall
- Possible increase in droughts due to lack of rainfall
- Increase in tropical cyclones due to increased water vapor in the air
