Although there are many negative effects of climate change, there are some advantages too.
The Arctic, Antarctic, Siberia and other frozen regions of the Earth may experience more plant growth and milder climates.
The next ice age may be prevented from occurring. Many scientists believe that the planet is due to enter the next ice age and enhanced global warming will prevent this.
The Northwest Passage through Canada's formerly icy north will be opened up to sea transportation. This will make trade easier and cheaper.
There is likely to be fewer deaths or injuries due to cold weather, meaning populations may grow.
Longer growing seasons could mean increased agricultural production in some local areas. This is a benefit to places such as the UK as more crops could be grown, with the possibility of double cropping.
|Impact on||Effect||Negative consequence||Positive consequence|
|Health||Malaria and cholera increase, due to temperature increase||More money needed to fight disease, strain on medical services, rise in death rate||No positive outcome|
|Vegetation||Shifting flora and fauna to different areas. Extinction of some species||Spread of pests and disease, alteration in crop yields, may increase food shortages||Canadian Prairies could become major wheat growing belt. Areas able to grow different crops, for example, citrus fruits in the UK|
|Weather||More extreme climates in inland locations. More frequent and devastating hurricanes||Unknown at present||Unknown at present|
|Ocean||Sea temperatures increase, sea levels rise, shift in ocean currents||Changes in size of fish stocks and their location will impact the fish industry||Increase in fish stocks in certain areas|
|Landscape||Reduced snow cover in some areas. Glaciers melt in Antarctica||Rise in sea levels||Extended summer season in some landscapes due to higher temperatures, increasing revenue|
|Hydrology||Reduction of wetland areas, as precipitation is reduced. In some places river flooding may increase||Great pressure on water supplies. Problems for HEP schemes and irrigation||Increased awareness of water conservation measures, less water wastage|
|Population||Reduction of areas suitable for human habitation, for example, lowland Bangladesh||Increased population densities increase possibility of disease and malnutrition||Forced movement of population from densely populated coastal areas, to less populated interior locations|
|Climate||Location of jet stream may alter. Depressions may shift south, causing them to be more intense||Better forecasting needed to warn people of approaching storms. Insurance premiums will increase||More accurate weather forecasting developed|
