Abstract



Global warming is causing an increase in the warmth of the Earth's surface. In behalf of the incorporation of pieces of polar ice,sea level rise suffered 4-8 inches over the past century, and possibly, there will continue increasing. The dimension and incidence of rain has also dilated due to expand evaporation of surface water. It is caused by the increment in the temperature. Nowadays this is the major issue people around the world is facing out.
The Present of Our PlanetScientists around the world have evaluated our planet and they say that the common temperature of the Earth's surface can reach up to 4.5 º F increase during the next 50 years, and up to 10 º F during this century. This accretion in water evaporation will derive from an increment in force and recurrence of hurricanes and storms. It will additionally be the origin of soil condensation isdecreased due to the high rate of vaporescence, and sea level ascends a standard of approximately 2 feet off the seashore of the Americas and the Caribbean.

General Consequences
The atmospheric heating has brought a lot harmful consequences for humans. Now we can see variations in weather to justify it. The humanity is contribuiting whitht he use of sprays, dusts an aerosols now they areapplied every where, this insecticides more than kill insects, are helping to destroy the biosphere of our planet. ( Mueller, G. p. 403). the global temperature has increased by about 0.8 ° C, the heat affects rainfall because the method of evaporation is accelerated to have higher temperatures, and this multiplies the humidity in the air and precipitation that affect the entire planet. Thecauses are repeated floods and landslides, causing vast human and material losses. The national yearly precipitation has increased between 5 and 10% since the early twentieth century, mainly as result of heavy rains in some areas.
Paradoxically it increases evaporation and rainfall caused fatal floods, severe droughts in summer originates, also causing losses of any kind due to the immenseheat, the same heat brings fires devastate forests and cities.
In 2002, the western states of the United States had its worst wildfire season in the last 50 years, nearly 3 million acres burned in Colorado, Arizona and Oregon, which had their worst seasons.
A heated atmosphere is producing the melting of the poles, an expansion in sea level. This phenomenon has been recorded inrecent years. It has not brought serious outgrowths for humanity, but to continue well in a few years could flood cities, which have almost completed at sea level.
Rising global temperatures will stimulate the melting of icebergs and ice caps and provoke early snowmelt in rivers and lakes.
Temperatures around Antarctica have raisin five times the global average over the past 50years. Today, the average temperature is 2.5 ° C. It is higher than that recorded in 1940. The phenomenon has also been recorded in the Arctic Ocean.
According to the NASA, the polar ice cap is melting at an alarming rate of 9% per decade. The Arctic ice thickness has declined 40% since the 1960s.
It is expected that the current scale of sea level rise increase the result of thermaldevelopment the oceans and melting of glaciers and partial ice sheets of Antarctica and Greenland. The results include loss of coastal wetlands and barrier islands, as well as an increased risk of inundating in coastal communities. Low areas as the coastal region of the Gulf of Mexico and estuaries like Chesapeake Bay is especially vulnerable.
