The major effects of global warming is the climatic change that is being absorbed on the earth. There are floods in the areas where the flood history is not very common. There are droughts in places, which were having good rainfall earlier. The atmosphere gets suddenly very harsh in the terms of cyclones and thunderstorms. The nature of earth's atmosphere is becoming even more unpredictable and hence a cause of attention. This in turn brings about a variation in the biological systems essentially the crops, forests, oceans, fresh waterways, and grasslands. As these are the building and breeding grounds of life, the life on earth is getting affected.
Then effect of Global Warming has been noticed in the behavior of the wild life. There has been extinction of various species due to global warming. Major changes are seen in the animals as they react to the warmer environment, which are caused due to global warming. A behavior pattern of the animals studied shows that the animals are beginning to shift their population towards north or towards a higher altitudes. A simple study that was made in the university of California on a small butterfly is enough to depict the changes in the availability of species in the warmer areas. A survey at one hundred and fifty one areas showed that the butterfly were getting less populated in the southern areas which were warmer as compared to the northern areas. Hence the butterflies have migrated from warm southern zone to cooler northern zone.
The effect will be on the vegetation that is available on the earth surface. The tundra type of vegetation will turn to temperate, cold deciduous and evergreen type of forest. Woody plant population will tend to increase as a result of increased precipitation. There will be a drastic change in the type of vegetation available in the area, which will in turn effect the inhabitation of the area.
species like golden toad, harlequin frog of Costa Rica has already become extinct. There are number of species that have a threat of disappearing soon as an effect of global warming. As an effect of global warming various new diseases have emerged lately. These diseases are occurring frequently due to the increase in earths average temperature since the bacteria can survive better in elevated temperatures and even multiplies faster when the conditions are favorable. The global warming is extending the distribution of mosquitoes due to the increase in humidity levels and their frequent growth in warmer atmosphere. Various diseases due to ebola, hanta and machupo virus are expected due to warmer climates. The global warming is expected to cause irreversible changes in the ecosystem and the behavior of animals.
The effects of global warming are very large in number and still there are so many that are still to be found out. But recently the problem has become visible and evident due to happening of the events that were before just talked off.
