Probably accentuate both the intensity and frequency of hurricanes and tropical cyclones in the area, and would extend to latitudes today unaffected or outside the scope of these natural phenomena.

The Earth’s climate is very difficult to predict, because there are many factors to consider: rain, sunshine, wind, temperature … So you can not define exactly what the effects will lead to global warming. But apparently, climate change could be very severe.

A first consequence, very possible, is the increase of drought: in some places the rainfall decrease. In others, the rain will increase, causing flooding.

A warmer atmosphere could cause the ice near the poles to melt. The amount of water that would raise the sea level. An increase of only 60 cm would inundate the fertile lands of Bangladesh, India, of whom depend on hundreds of thousands of people to obtain food. Tropical storms may occur more frequently.

The current child is one of the clearest examples of the problems that global warming brings, unbalanced state of global climate causing too much rain in some places to floods and other is totally a drought, you can also cite the abrupt change temperature and pressure in the atmosphere which results in long sequences of tornadoes and typhoons. This is more in tropical areas where tornadoes occur in the time of year and climate change these very often reappear.

We know we can expect the consequences of the greenhouse effect for the next century, if not return to lower values:

- Increase in average global temperature.
- Increased drought in some areas and flooding in others.
- Increased frequency of hurricane formation.
- Progressive melting of polar ice caps and consequent rise in sea levels.
- Increased precipitation at the global level but fewer days and more rain in torrents.
- Increased number of hot days, resulted in waves of heat.

A similar rise would mean the contamination of aquifers, the recession of coasts and wetlands, up to 15% of the fertile land of Egypt and 14% of Bangladesh would be flooded by rising maximum. Possibly affecting the stability of tropical forests and biodiversity, due to its high degree of vulnerability to environmental changes in the balance, being replaced by degenerated ecosystems.

Coral reefs contain the greatest genetic diversity after tropical forests, including one third of all fish species known. Most are on average water temperatures approach the maximum tolerable without submitting changes in its symbiotic balance.

If the sea temperature rises by 2 0 3 ° C, the stability of some corals would be threatened. Projected increases in sea level also affect their ability to survive, because the stability of coral reefs is associated with the maintenance of a certain distance from the water surface.

The expected warming far exceeds the capacity of migration of natural communities, resulting in destruction without replacement and impoverishment of ecosystems, species loss and ultimately loss of the earth’s capacity to support life. Perhaps industrialized agriculture to respond to the new situation quickly enough (although in the U.S. heat wave of 1988 represented a 30% decline in the harvest of grain), but agriculture in developing countries has no means an such adaptation.

There are many powerful phenomena whose evolution climate change is uncertain, for example, the consequences of an ice-free Arctic Ocean sea currents and their influence on the fishery, or the likely movement of tropical diseases to other parts of the Earth.

Examples such as malaria and dengue fever could spread over a greater proportion of land area, affecting millions of people who are now outside their areas of influence.

However, in a study entitled ‘Environment and Human Security’, have indicated that there is still time to reverse this situation if steps are taken and improved weather forecasting systems worldwide.

Catastrophic flooding

Experts added that this situation of alarm was evident late last month with the floods that devastated farmland in Haiti and the Dominican Republic and caused more than a thousand deaths.

Created by the UN General Assembly in 1973, the University brings together experts in research, training and dissemination of knowledge related to pressing global problems.

The experts added that an estimated one billion people, ie one sixth of world population living in areas that will be the scene of the worst floods of the century.

Currently, only floods affecting over 530 million people worldwide, causing an average of 25,000 deaths a year, destroying homes, disease and loss of crops and livestock.

Irrational use of land

According to experts at the university, this situation has been exacerbated by the unsustainable and irrational use of land and other human actions.

“In a world more humid and hot as science predicts, the upper Northern Hemisphere will likely see more storms, while summers in some inland areas will be drier and prone to drought,” said Janos Bogardi, director of study.

According to the study, the most affected region will be Asia, where during the last decades an average of more than 400 million people have been hit by floods.

The experts have reported that the annual cost of floods and other climate-related disasters (mainly in developing countries) is between 50,000 and 60,000 million dollars, a sum equivalent to all the development aid given to countries donors.

Widespread problems

But problems are not limited to developing nations, also affect the industrialized countries, said the report. In Europe, the flood caused a hundred deaths in 2002, affected 450,000 people and caused losses estimated 20,000 million.

In the U.S., where 50 people died and damage was done by over 50,000 million due to overflow of the Mississippi River in 1993, floods are charged an average of 25 persons each year since 1980.

According to experts of the United Nations University, these problems will double in the areas most likely due to an expansion of climate processes (droughts or floods), the increase in sea levels and the continued deforestation.

“What is needed most urgently to the increasing risk of flood disasters is greater global capacity to monitor and forecast extreme events” of the climate, has emphasized Bogardi.

“With better information, you can install better warning systems and infrastructure to identify new strategies,” he added. But more than anything, according to the expert, “what is needed is to change the international mindset of the reaction (…) and charity to anticipation and prevention.”

The countries are very generous when it comes to help after the disaster, but much less so when it comes to making preparations to face, he added.

1. Earth will cover with water. Floods and earth quake will happen again and again.
2. Antarctica will be melted in water and it resultant flood.
3. Animals will be dead and many diseases will occur without notifications.
4. Trees will be died and we shall not get oxygen properly to live.

5. We shall not get proper and healthy food for our life, we shall have to use artificial foods.
6. We shall not get any protection from nature.
7. Nature will refuse us and nature will not help us to live.
8. We shall have to face different nature deadliest things like: earth quake, flood, storms, and many other things.
