CLIMATIC CHANGES

.Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years)..Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions (i.e., more or fewer extreme weather events).

Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as "global warming“.

A gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the green house affect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in a planet's atmosphere warm its atmosphere, which is one of the causes of global warming.

Our ever increasing addiction to electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere. Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply.

Rise in temperature Rise in sea level The ice sheets melt because of so much heat, and results in the rise of the level of sea water Heavy rainfall across the globe Extreme drought Excess heat leads to a drought Hurricanes

The green house effect is another reason for the climate change.

Leads to Global Warming Leads to Pollution

Most of us already know that a thin layer called as the ozone layer protects our earth from UV rays.

TOP 10 POLLUTED CITIES IN INDIA Delhi Ludhiana Agra Amritsar Raipur Patna Firozabad Ahmedabad Kanpur Gwalior

New Delhi most polluted in the world ! United States produces 30% of the world’s waste and uses 25 % of the worlds natural resources. Children contribute to only 10% of the world’s pollution but are prone to 40% of global disease. More than 3 million kids under the age of 5 years die every year due to environmental factors like pollution. Recycling alone have prevented 85 million tons of waste to be dumped in China is the world’s largest producer of carbon dioxide. United States is number 2.

Almost 80% of urban waste in India is dumped in the river Ganges.

Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. PLEASE BE ALERT

RISING TEMPERATURES WILL CAUSE :  DROUGHTS  HEAT WAVES  FLOODS

A PROLONGED PERIOD OF ABNORMALLY LOW RAINFALL,LEADING TO A SHORTAGE OF WATER.

A HEAT WAVE IS A PROLONGED PERIOD OF EXCESSIVELY HOT WEATHER,ACCOMPANIED BY HIGH HUMIDITY.

FLOODS A Flood is an overflow of water that submerges land which is usually dry. Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers.

GREEN HOUSE EFFECT

WILL LIKELY INCREASE THE FREQUENCY AND STRENGTH OF EXTREME EVENTS SUCH AS FLOODS, DROUGHTS AND STORM WARMER CLIMATE IS EXPECTED TO BOTH INCREASE THE RISK OF HEAT- RELATED ILLNESSS, DEATH AND WORSE CONDITIONS FOR AIR QUALITY. CLIMATE CHANGE S THAT THREATEN HUMAN SAFETY AND HEALTH

WEATHER IS WHAT’S HAPPENING OUTSIDE YOUR WINDOW RIGHT NOW. CLIMATE IS THE AVERAGE OF MANY YEARS OF WEATHER OBSERVATION.
