Impact of Social and Political
Changes in weather and ocean can lead to the emergence of diseases associated with heat (heat stroke) and death. Hot temperatures can also cause crop failures that will appear hunger and malnutrition. Changes in extreme weather and increased sea levels due to melting Arctic ice could lead to diseases associated with natural disasters (floods, hurricanes and fires) and deaths due to trauma. The emergence of natural disasters is usually accompanied by the displacement of people into refugee camps places where the disease often occur, such as: diarrhea, malnutrition, micronutrient deficiencies, psychological trauma, skin diseases, and others.
Shift in the ecosystem can impact on the spread of diseases through water (Waterborne diseases) and the spread of diseases through vectors (vector-borne diseases). Such as increased incidence of Dengue Fever since the emergence of the (ecosystem) of this new breed mosquitoes. With this adamya climate change there is a species of disease vectors (Aedes Agipty eq), viruses, bacteria, plasmodium become more resistant to certain drugs that target these organisms adala it. Also predictable that there are some species that are naturally selected perbuhan or extinct due to this extreme ecosystem. this will also affect climate change (Climat change) the bus to the increase in cases affecting certain diseases such as ARI (drought / forest fires, DHF association with erratic rainy season)
Gradient Environmental pollution caused by waste in the river also contributes to waterborne diseases and vector-borne disease. Coupled with air pollution emissions of gases that are not controlled factory will further contribute to disease, respiratory diseases like asthma, allergies, coccidiodomycosis, heart disease and chronic lung, and others.

Ecological Disturbance
Ecological Disturbance
Animals and plants are living creatures that are difficult to avoid the effects of warming because most of the land has been controlled by humans. In global warming, animals tend to migrate toward the poles or to the mountains. Plants will change the direction of growth, seeking new areas as old habitats grow too warm. However, human development will prevent this movement. The species that migrate to the north or south is blocked by the cities or agricultural lands may be dead. Some types of species that are not capable of quickly moving toward the poles may disappear.

One might assume that a warmer Earth would produce more food than ever before, but this is not the same in some places. Southern Canada, for example, may benefit from more rainfall and longer growing season. On the other hand, semi-tropical agricultural land dry in some parts of Africa may not be able to grow. Desert agricultural areas that use irrigation water from the mountains far may suffer if the snowpack (snow collection) winter, which serves as a natural reservoir, melts before the peak months of planting. Crops and forests may experience insect and disease attacks more powerful.

Improving the Sea Surface
Improving the Sea Surface
Changes of average height measured from sea-level areas with a stable environment in geologi.Ketika atmosphere warms, the ocean surface layer will be warmer, so the volume will grow and raise the sea level. Warming will also melt much glacier ice, especially around Greenland, further swelling the sea. Sea levels worldwide rose 10 - 25 cm (4 - 10 inches) during the 20th century, and IPCC scientists predict a further rise of 9 to 88 cm (4 to 35 inches) in the 21st century.
Sea-level changes will complicate life in the coastal region. Increase of 100 cm (40 inches) will submerge 6 percent of The Netherlands, 17.5 percent of Bangladesh, and many islands. Erosion of cliffs, beaches, and dunes will increase. When the high seas to reach the mouth of the river, flooding caused by high water will rise on the mainland. Rich countries will spend huge amounts of money to protect the shorelines, while poor countries may simply evacuate from coastal areas.
Even a modest rise in sea level will greatly change coastal ecosystems. Increase of 50 cm (20 inches) will submerge about half of coastal wetlands in the United States. New marshes will form in, but not in urban areas and regions that have been built. This sea-level rise will cover much of the Florida Everglades.

Climate Start Unstable
Scientists use computer models of temperature, precipitation patterns, and atmosphere circulation to study global warming. Based on these models, scientists have made several predictions about the impact of global warming on weather, sea levels, coastal, agricultural, wildlife and human health.
[edit] Climate Start Unstable
Scientists predict that during global warming, the northern part of the Northern hemisphere (Northern Hemisphere) will heat up more than other regions on Earth. As a result, icebergs will melt and the land will shrink. Will be less ice will float on northern oceans. Areas that previously experienced light snow, may not be there again. In the mountains in subtropical areas, snow-covered parts will be less and will melt faster. Growing seasons will be longer in some areas. Temperatures in the winter and at night would tend to increase.
Warmer regions will become more humid as more water evaporates from the oceans. Scientists are not sure whether the moisture is actually going to increase or decrease heating further. This is because water vapor is a greenhouse gas, so that its presence will increase the insulation effect on the atmosphere. However, the more water vapor will also develop a lot more clouds, which would reflect sunlight back into space, where it will reduce the heating process (see the water cycle). High humidity will increase rainfall, on average, about 1 percent for each Fahrenheit degree of warming. (Rainfall in the world has increased by 1 percent in the last hundred years) [29]. The storm will become more frequent. In addition, the water will evaporate faster than the ground. Some regions will become drier than before. Winds will blow harder and perhaps with a different pattern. Hurricane (hurricane) that obtain power from the evaporation of water, will become larger. Contrary to the warming is happening, some very cold periods will probably happen. Weather patterns become more unpredictable and extreme.
