Wake up !!!!


" The world is being hotter and hotter "
Why ? Due to 'global warming'
What is this?


Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.

Global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the twentieth century. The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations,"[1] which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes have probably had a small warming effect from pre-industrial times to 1950, but a small cooling effect since 1950.[2][3] These basic conclusions have been endorsed by at least 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. The American Association of Petroleum Geologists is the only scientific society that officially rejects these conclusions.[4][5] A few individual scientists disagree with some of the main conclusions of the IPCC.[6]

Climate models referenced by the IPCC project that global surface temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100.[1] The range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a millennium even if greenhouse gas levels are stabilized.[1] This reflects the large heat capacity of the oceans.

An increase in global temperatures is expected to cause other changes, including sea level rise, increased intensity of extreme weather events, and changes in the amount and pattern of precipitation. Other effects include changes in agricultural yields, glacier retreat, species extinctions and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the exact degree of climate change expected in the future, and how changes will vary from region to region around the globe. There is ongoing political and public debate on a world scale regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences. Most national governments have signed and ratified the Kyoto Protocol, aimed at reducing greenhouse gas emissions.

Terminology

The term "global warming" is a specific example of the broader term climate change, which can also refer to global cooling. In common usage the term refers to recent warming and implies a human influence.[7] The United Nations Framework Convention on Climate Change (UNFCCC) uses the term "climate change" for human-caused change, and "climate variability" for other changes.[8] The term "anthropogenic climate change" is sometimes used when focusing on human-induced changes.

Quotes on the Flag of India.











  • "The weakest numerically occupy the first place, the Islamic colour (green) comes next, the Hindu colour (red) comes last, the idea being that the strongest should act as a shield to the weakest."
On significance
  • "to represent the equality of the least of us with the best, an equal part is assigned to all the three colours in the design.
On the Charkha
  • "But India as a nation can live and die only for the spinning wheel .... No industrial development schemes can solve the problem of the growing poverty of the peasantry of India.... India is not a small island, it is a big continent which cannot be converted like England into an industrial country. And we must resolutely set our face against any scheme of exploitation of the world. Our only hope must centre upon utilising the wasted hours of the nation, for adding to the wealth of the country, by converting cotton into cloth in our cottages.... It follows that the flag must be made of Khaddar, for it is through coarse cloth alone that we can make India independent of foreign markets for the cloth."
  • "The charka symbolizes energy," he wrote, "and reminds us that during the past eras of prosperity in India's history, hand spinning and other domestic crafts were prominent."
  • "It will be necessary for us Indians -- Hindus, Muslims, Christians, Jews, Parsis and all others to whom India is their home -- to recognise a common flag to live and die for."
  • "Bhagwa or the saffron colour denotes renunciation or disinterestedness. Our leaders must be indifferent to material gains and dedicate themselves to their work. The white in the centre is light, the path of truth to guide our conduct. The green shows our relation to soil, our relation to the plant life here on which all other life depends. The Ashoka Wheel in the center of the white is the wheel of the law of dharma. Truth or satya, dharma or virtue ought to be the controlling principles of those who work under this flag. Again, the wheel denotes motion. There is death in stagnation. There is life in movement. India should no more resist change, it must move and go forward. The wheel represents the dynamism of a peaceful change."
" This flag is of Indian Independence. Behold, it is born. It is already sanctioned by the blood of martyred Indian youths. I call upon you gentlemen, to rise and salute this flag of Indian Independence. In the name of this flag, I appeal to lovers of freedom all over the world to cooperate with this flag in freeing one-fifth of the human race. "
