Global warming or the high averages of global temperatures are caused by natural as well as human induced reasons. Though many people do not believe that global warming exists, evidences are coming up from all parts of the world supporting the occurrence of global warming. Many people are conveniently ignoring the warning signs produced by the earth; the important evidence of global warming is the temperatures itself. The average temperature across the world is higher than the previous years. Many areas are experiencing the highest temperatures ever recorded. There is evidence that due to this rise in temperature even the ...view middle of the document...
There are pictorial evidences and some proofs of melting polar caps and receding glaciers. The desert area in some countries like Africa is spreading as it is evident from the aerial photo graphs of the desert. Tsunamis are become regular in occurrence. Tsunamis, hurricanes and floods are causing substantial damage to the life and possessions of the people around the world. All these changes are affecting the productivity of the earth. In many parts of the world people are starving, as agricultural practices are impossible due to non-availability of water or drought. Africa is one good example; the number of people starving in Africa has grown to large numbers due to the drought conditions prevailing there. If global warming still continues, scientists are of opinion that the same scene can be seen in various other parts of the world also.
Another indication of global warming is the rapid spreading of vector borne diseases. Vectors like mosquitoes and house flies are increasing; as a result the diseases caused by them are also in the rise. Evidences show that the mosquitoes are getting much longer period for breeding as the summer season is getting prolonged due to global warming. The unpredictable weather conditions like hurricanes and rains provide standing water and wet or damp areas needed for the breeding of mosquitoes. Already diseases spread by mosquitoes like dengue and malaria is spreading in different parts of the world. There are evidences that the bird flu viruses get more active when temperature rise and the incidences of bird flu are rising every year.
Evidences show that fueled by global warming many countries has undergone severe changes in its precipitation pattern. There are evidences showing the polar place like Alaska is getting hotter and the natives have started wheat cultivation. Some archipelagos have already lost some of their islands because of the rising of sea level caused by global warming. The number of hot days is gone up in summer. Not only that the night minimum temperature has gone up in many places in the world all these are real evidences of increasing average global temperature or generally speaking the global warming.
Thus global warming is not just a theory as some scientists put it; but it is a scientifically proven fact. If the carbon...
