Our atmosphere is the biggest waste unit in modern time. It handles both the gaseous or the other kind of wastes that come from day to day activities of humans. It is also found that it has a ability of self cleaning. Many air pollutants disappear from atmosphere after some days after their addition to atmosphere. Some least soluble compounds are oxidized and are changed into water, carbondioxide and compounds that are soluble in water for their quick removal.
The cleaning capacity is low for some compounds as a result they will be present in air for a longer time.However air pollution and change in climate condition are directly related.Increase in levels of the green house gases alter the balance of energy among the atmosphere and surface

It is brought about by different activites whether they are natural or natural activities. Natural activites may include biotic methods,different amount of sunlight radiation received on earth,tectonic plates or eruptions from volcano whereas human activites includes the pollution arising from activities of industries and other sources producing greenhouse gases. Human activities are the critical reason for the increase climatic change.
Gases like carbon dioxide have capacity to mop up all the spectrum of infrared light leading to increase in the warming of the atmosphere. The gases once absorbed are present in the atmosphere for hundred or thousand of years.
CAUSES OF CLIMATIC CHANGE
Most scientist give the major cause of climate change that is greenhouse effect.Factors which can shape climatic conditions are referred to as climate forcings or forcing mechanisms. These mechanism includes processes like variation in solar radiation,variation in earth’s orbit and the changes taking place in greenhouse gas concentration
Forcing mechanism are internal or external.Internal forcing mechanism are the natural process in the climate whereas external forcing mechanism are natural or anthropogenuic.
Some causes that leads to the change in climatic conditions

The change in climate may also change many of these communities. Climate change also have a affect on tourism and recreational activities. A warming climate and changes in precipitation patterns will likely decrease the number of days when recreational snow activities such as skiing and snowmobiling can take place. In the Southwest and Mountain West, an increasing number of wildfires could affect hiking and recreation in parks. Beaches could suffer erosion due to sea level rise and storm surge. Changes in the migration patterns of fish and animals would affect fishing and hunting. Communities that support themselves through these recreational activities would feel economic impacts as tourism patterns begin to
The air that we breathe is contaminated by the harmful air in the earth’s
this occurs when pollutants in the air have a chemical reaction. This is very effective against the atmosphere. But if we all use different sources like battery powered cars ten we could use our limited supply of fossil fuels for other more important things, or just leave it alone. Not only is there battery powered cars, but we also have wind powered cars. These could be very important, and you can’t tell me this isn’t really cool!
When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for
Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results. The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for this problem.
1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.
One of the biggest cause has been the exhaust gasses. The climate change has some effects on the ocean. One of the most well-known affects would be the melting of ice. Due to the climate change the temperature rises, because of this, masses of glaciers and ice sheets are melting. The melting of the glaciers and the ice sheets brings several affects.
There can also be many causes in disruption of habitats and this can lead to many animal species to extinction. Global warming is a rise in the surface temperature of the earth. The issues that cause Global warming are divided into two categories natural and human influences. There are some natural reasons why Global warming is occurring. The climate has continuously
Global Warming Proposal Introduction The phenomenon of constant increase in the earth’s temperature is known as global warming. The excessive use of fossil fuels is destroying our environment as well as wildlife. It is a great threat to human life too, as this activity is causing intense pollution and also results in damaging the ozone layer.
Do humans cause global warming or is it natural? Many researchers, scientists, and environmentalists are expressing concerns about changes in the overall climate of the `earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. What is global warming? Global warming is an increase in the average temperature at Earth's surface (“global warming”).
Climate change is the most rising issue of the modern world that is threatening our planet from the last few decades. In the simplest definition, the term climate change refers to the rising of the planet’s temperature, particularly an increase in the average atmospheric temperature. It should be noted that in the last few decades, many scientists and ecologists has discovered the Earth temperature is increasing at an alarming rate and has affected the planet in numerous of way. The constant change in the climate due to various causes is threatening the preservation of the Earth and its human life. It should be noted that the climate change is linked with several of the human activities that are further directed towards the global warming.
Lastly, I would give ways on what you can do to have cleaner air. II. Body a. To begin with, pollution can be
Throughout history Earth`s climate has changed a lot, and there is a lot of evidence that shows how humans have contributed to this changed and effected the Earth. Just in the last 650,000 years there have been seven cycles of glacial advances, the increase in the thickness and area of a glacier. As well as glacial retreats, a condition occurring when backward melting at the front of a glacier takes place at a rate exceeding forward motion. Most climate changes are attributed to very small variations in the earth`s orbit, that change the amount of solar energy our planet receives. The 21st century has seen the most temperature records broken in recorded history.
Global warming is the change in the average temperature of the earth is surface as a result of humans’ activity that pollutes the nature. The level of carbon dioxide has been increased in the upper part of the atmosphere which it leads to increase the average temperature on the surface which it causes many problems in many side of life including nature, health and economy. Increasing the concentration of carbon dioxide is due to release of poison gases to the atmosphere by cars, manufactures, oil field, burning of natural gases and smoking. Air pollution and climate change are a result of increasing the level of carbon dioxide around the world.
Focusing on reducing air pollutants in the Earth’s atmosphere, it creates an environmentally healthy place to live in and encourage people to work together for a common cause, thus making the world a better place. In order to solve such a problem, a strong understanding is needed. Air pollution is one of the various forms of pollution. It is the presence of foreign toxic substances or pollutants into the air.
As the glaciers, snow and ice melt, sea levels will rise which can cause erosion and destroy habitats. Also, the Arctic habitat hosts many species itself, such as polar bears, arctic foxes, and walruses. Without these land masses, hunting, mating and resting are harder to do which results in the species dying out. There are also many droughts that are occurring which affects many species including humans. Many ponds that contain wildlife are drying up and many freshwater bodies are being depleted.
