Global Warming

Global Warming reference to the change in surface temperature of the Earth, which results in climatic change. This has been happening ever since man started interfering with environment.

Human wants have been increasing with the increase in population exploitation of the environment continues to be a major threat. Large-scale development of industries and transport have contributed to pollution. The largest human influence has been the emission of green house gases such as CO2, methane, nitrous oxide, etc, through major industrialization, CO2 being the main couse of depleting Ozone layer. The global surface temperature is likely to raise from 2.6 to 4.8°C, which will differ from region to region.
The adverse effects of global warming are:
1) Raise in sea levels due to rapid melting of ice(glaciers).
2) Change in rainfall pattern
3) Expansion of deserts
4) Extreme weather conditions like heat waves, droughts, heavy rainfall with floods and heavy snowfall.
5) Extinction of species due to shifting temperature regimes
6) Threat to flood security from decreasing crop yield.
The United Nations Framework Convention on climate change is aiming at reducing deep cut emissions. Public reactions to global warming and concern about it's effects are also increasing. So, let us do our bit by creating awareness and work hard towards a better tomorrow.

Ex- Bombing at a graduation ceremony at a Medical College, in Mogadishu has been ranked as the most devastating loss of human life in recent history. Natural disasters such as earthquakes, famines, floods, landslides, etc, have also led to serious destruction to life and property.* The problems that generally arise after a disaster lead to diseases associated with poor water supply and sanitation. At times health centres too are damaged and erratic delivery of medicines and care lead to further problems. The W.H.O. in the past and present facade has made immense progress in the nature of dealing with emergencies in public health during disasters. They aim at: 1) Assessing the nature and magnitude of the disaster 2) To treat the injured 3) To recover bodies 4) To set-up surveillance for infectious diseases 5) Pr...

He studied approximately 60 nations before drafting the Indian Constitution. That is why he is called the 'Father of Indian Constitution'.     The Indian Constitution has 448 articles, 103 amendments and 12 sche...
