Global warming will have serious impacts on the environment and on society. Higher temperatures will cause a melting of ice in Greenland and Antarctica. This will accelerate the rise of sea level. The speed at which global warming is expected to occur in the 21st century is faster than most plant and animal species will be able to cope with. Some will adapt but others will suffer and may become extinct.
Global warming will affect agriculture. New crops will be able to be grown in areas that are currently too cold to support them. However, more pests and diseases may offset any benefits higher temperatures may have. Water resources will also be affected. Some reservoirs may dry up if temperature increases, especially if rainfall also decreases. Rising sea levels may pollute fresh groundwater supplies with salt water.
Global warming will also affect human health. There may be more heat-related illnesses in hotter summers, and increased breathing problems as higher temperatures increase air pollution in cities, reducing air quality. The malaria mosquito may also be able to spread to other regions of the world where it is currently too cold to survive and breed.
More extreme weather, for example storms, floods and droughts will have severe impacts on the environment and on society. The poorest people in society will unfortunately be those least able to cope with the impacts of global warming.
If you increase your personal petrol or gas consumption for this year by say 1'000 litres because you use the car more often, will this lead to natural disasters? And if yes, where? Nobody will be able to take you to the court, because it is not possible to prove a direct relation between your increased yearly consumption of fuels and a drought in Africa. This does not change the fact, however, that the CO2 emission produced by your car does indeed contribute to the global warming. No doubt, you and I are responsible for... [continues]
