"Climate Change"

DESTRUCTION OF THE SCENIC MARVEL OF THE EARTH






"There are in nature neither rewards not punishments- there are consequences. Nature is but a name for an effect whose cause is God.


   
Weather is blue skies and puffy white clouds, torrential rains with gale force wind twisters;

flashes of lightning; or snow gently falling to the ground. The weather is the state of the atmosphere at any given time, it is experienced everywhere on earth, it varies considerably from place to place, day to day, and season   to season. The long term look at the weather in a place or region, the averaging of rainfall, the maximum and minimum temperatures is called climate. Climate in addition to the "averages" in the weather also   includes and frequencies of “extremes" in the weather. But the said climate is turned wild that is now Climate Change. Climate Change has long-since ceased to be a scientific curiosity, and is no longer just one of many environmental and regulatory concerns. It is a growing crisis with economic, health and safety, food production, security, and other      dimensions.   Climate change can be affected by natural factors, such as changes in volcanic activity, solar output, and the Earth’s orbit around the Sun. In terms of the Earth’s energy balance, these factors primarily influence the amount of incoming energy. Volcanic eruptions are episodic and have relatively short-term effects on climate. Changes in solar radiance have contributed to climate trends over the past century but since the Industrial Revolution, the effect of additions of greenhouse gases to the atmosphere has been about ten times that of changes in the Sun’s output. Climate change can also be caused by human activities, such as the burning of fossil fuels and the conversion of land for forestry and agriculture. Since the beginning of the Industrial Revolution, these human influences on the climate system have increased substantially. In addition to other environmental impacts, these activities change the land surface and emit various substances to the atmosphere. These in turn can influence both the amount of incoming energy and the amount of outgoing energy and can have both warming and cooling effects on the climate.  The dominant product of fossil fuel combustion is carbon dioxide, a greenhouse gas. The overall effect of human activities since the Industrial Revolution has been a warming effect, driven primarily by emissions of carbon dioxide and enhanced by emissions of other greenhouse gases.
