What is climate change? The world climate change includes humidity wind and season .climate change affects more than just a change in a weather .it also refers to seasonal change over a long period of time. It play a fundamental role in shaping natural ecosystem, the human economics and cultures that depend on them .Many system are tied to climate, a change in climate can affect many related aspect of where and people, plant and animals live, such as food production availability and use of the water and the health risk.
The Changes in the atmospheric concentrations of the greenhouse gases and in the ice cover, which have been have been invoked to explain the drastic change in the weather and temperature patterns over the years. Over the entire world, in Pakistan too, these changes have resulted from the effects of human activities and the destruction of the earth's protective ozone layer. Although the human induced warming is among the most pervasive threats to the web of the life, the burning of fossil fuels; coal, gas and oil, is dangerous too, as it releases Carbon-dioxide (CO2) into the atmosphere.
What is global warming?
Global warming is when earth heats up and the temperature rises. It happens when greenhouse gases (water vapor, carbon dioxide, methane and nitrous oxide) trap heat and light from the sun in the earth's atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. There are many natural causes of global warming .One of these causes are that they do not account for the extra warming we are currently seeing on our plant. The current warming we are by humans is anthropogenic the question is how do human causes global warming? The global warming is accelerating the human created emissions of greenhouse gases. The carbon dioxide knows as the primary gas is released every time you use fossil fuel which is currently our main source of energy. With the help of secure future for human you can help stop those emissions.
Global diming:
Global diming is the opposite of global warming .when the earth temperature decreases or the earth temperature is cold it is known as global diming .Global diming is probably due to the increased presence of aerosol particles in the atmosphere such as smoke, air pollution, among and CS gas. It is also dangerous for the environment and humans. Latest research tells us that the presence of aerosol particles may have increased the carbon sink in the ecosystem of earth due to which the environment is not safe and healthy any more for the humans. Due to global diming the process of photosynthesize cannot be performed, which harms almost every living organism in the world.

Global Warming and Climate Change (ARICLE)
The recent changes in the temperature of the Earth has been evident from the events like floods caused by rapid melting of glaciers, record level cold spells experienced in areas like UK. This Earth's natural phenomenon has been labeled by many terms by the experts including climatic change or the famous terminology used as the 'Global warming'. It is popularly defined as the warming up of the Earth's climate due to natural and man-made activities such as greenhouse effect etc. There has been a heated debate about this issue on its authenticity and its causes etc.
In order to understand this phenomenon it is important to study how did past changes in the Earth's climate have contributed to this Global warming. According to the article, 'what does past climate change tell us about global warming?' (James Wight) the author highlights the fact that some are of the belief that the Earth's history is filled with drastic climatic changes, long before SUVs and coal-fired power plants so that's why this recent changes in climate cannot be the making of mankind. The principle behind Earth's climate is heat. It is the heat that governs its temperature. "When you add more heat to the climate, global temperatures rise and earth temperatures also rise. Conversely, when the climate loses heat, temperatures fall." It is due to this that the planet is forced into an energy imbalance that changes its global temperature. Nowadays the activities of humans are playing a part in escalating this energy imbalance. "Greenhouse gas increases climate change and global warming many times in Earth's history, and we are now adding greenhouse gases to the atmosphere at an increasingly rapid rate."
Many studies have been carried out on the periods where there have been temperature records and measurements of the various forcing which drove the climate change. A few studies examined that how much global warming is affecting us and how much it affect us in the future or the period around 12,000 years ago when the planet came out of a global ice age (Last Glacial Maximum) .These studies have claimed that doubling of carbon dioxide causes change in the global temperature. Therefore, past climate changes tells us that humans can invoke climatic changes in the Earth.
Despite these studies there still have been a heated debate whether this climate change or Global warming is actually a product of human activity or is just nature playing it's routinely role. Many experts and scientists have put forward their views regarding this.
Those who are of the view that global warming is basically a man made phenomenon, says that emission of greenhouse gases including carbon dioxide plays a vital role in the damaging of the ozone layer which has caused warming of the Earth's temperature. They say that this "carbon dioxide bloat results largely from burning of coal and other fossil fuels." This majority opinion has been disseminated in peer-reviewed reports over the past 20 years by the Intergovernmental Panel on Climate Change (IPCC), an entity established by the United Nations and the World Meteorological Organization.

A New Approach to Understanding Climate Change (article)
It is said that it is a phenomena (climate change) that exceeds far beyond science with some implication for economics, politics, sociology, and environmental issue. It is a fact that changes how people understand the world around them. It has to be understood by both points of view physically and mentally. An idea that is increasingly changing the society and the way of people think of the future. Lack of global consensus had issues surrounding mitigation, and adaption to climate change. The writer believe that WIREs Climate Change is a project that can play an active role in the construction of new knowledge about climate change by stimulating research reviews that demand new ways of thinking in both author and readers
GLOBAL WARMING CONTROVERSY (article)
The article (global warming and controversy) is about global warming controversy which means variety of disputes regarding the nature, and consequences of global warming. It's about the effect of human on global climate and what policies should be implemented to avoid possible effect of climate change. The trend is mostly human caused, and that may result a serious damage. The writer says that global warming is one of the reason of climate change and humans contributes a lot to global warming by using green house gases .Most of the scientists did assessment that most of the observed warming over the last 50 years is likely to have been due to the human-caused increase in greenhouse gas concentrations. Global warming is when the earth heats up. It happens when greenhouse gases (carbon dioxide, nitrous oxide, and methane) trap heat and light from the sun in the earth's atmosphere due to which temperature of the earth increases. This hurts many people, animals, and plants. Many cannot take the change, so they die. When the global warming increases it causes many diseases due to the presence of green house gases in the environment or atmosphere.
The Day "Global Warming"
According to an article, November 20, 2009: The Day "Global Warming" Ended by Alan Caruba (2010) stating that the global warming was just a hoax and was funded by many companies and government officials for their own benefit. It was this day that many e-mails of the top officials of these companies were leaked as pointing out to the fact that it was false.
Nevertheless both of the sides do claim the fact that the Earth's climate has changed since 1700s during the industrial Revolution. Another piece of the data is that everyone agrees with that the global average temperature has risen since 1850, when reliable instrument temperature measurements began, with most of the warming occurring since 1970.

PERSONAL OPINION:
Some people say global warming and climate change is a natural process some says it is man-made process (anthropogenic). Some people say global warming and climate change is a natural process because many natural processes like volcanic eruption contributes to global warming and climate change. My personal opinion is that it may be a natural process because volcanic eruption is a cause of climate change and global warming but human activates are more responsible because one of the biggest causes of global warming is anthropogenic activates performed by humans . Global warming occurs when earth temperature rises .volcanic eruption is a cause of global warming but I think man made pollution(anthropogenic) more contributes to global warming as compare to natural process because as we all know the population of the world increasing day by day more people means more pollution .When gasses such as carbon dioxide, methane, nitrous oxide and refrigerants create a greenhouse effect by trapping heat in the lower atmosphere due to which earth temperature rises and it causes global warming as well, people are contributed very much to the global warming by using these gases these gases are known as greenhouse gases. The damage to our environment has already started because due to global warming sea level also rises and will continues to rise as the world warms there will come a point when human life does not exist on the earth and due to the rise in temperature of earth sea level increase , due to the sea level the probability of more stronger hurricanes also high. Earth is surrounded by a layer and that layer is known as greenhouse effect .Green house effect is the process through which earth temperature remains normal but due to increase in global warming the green house layer also become thick .the natural reasons vary as climate change will always change due to increasing significantly the concentrations due to some gases in the atmosphere such as green house gases and mainly because of carbon dioxide gas which turn the earth surface warm we know that effects on wheatear is a part of climate change . Due to increase in temperature it will lead to increasing preset ration the causes of global climate change is to be a product of global warming which is a atmospheric phenomena the reasons for global climate change is mainly includes the intensity of solar energy or the earth temperature the change in level of carbon dioxide , rises in temperature is due to earth atmosphere green house gases is a part of the atmosphere which incensed the effect of green house gases which will slowly make the atmosphere heat ups. To reach the earth the green house effect created by the refrigerants prevents the same rays from escaping back into the atmosphere as sun rays the causing by the global warming the situation is commonly referred as the green house effect more and more green house gases are combined together more heat is trapped rise in the overall temperature of the earth. All fundamental causes of global warming is due to the depletion of the ozone layer ,the growth of hydrocarbon industries, disappearance of rain forest and the increase of live stock . The unexpected and unpleasant climate changes from natural causes will always be at risk. The situation today is that the rapid change in the climate is caused by people due to increasing demission of carbon dioxide and green house gases the prediction by the scientist which has a range of increased temperature due to carbon dioxide but obviously there is an upward trend. A fact which is not known is that global warming and climate change is manmade or if it is a natural process occurring with or without human intervention. I am supporting my point that human contributes a lot to global warming and climate change and anthropogenic is one of the biggest causes of global warming because the old ages didn't had the modern technology so the global warming rate was low due to un awareness of technologies and people use to live long life because there was no global warming at that time, as the technology increases pollution is also increases due to the massive usage of machineries and vehicles and due to the massive use of green house gases the global warming increase and many dangerous disease also appeared due to the massive use of green house gases . Green house gases is not good for us these gases are very dangerous. Green house gases can stay in the environment for an amount of years due to which many diseases also appears such as cancer, asthma, heart diseases. Most of the effects of manmade activities climate change and global warming won't be good. Due to Increased probability and high intensity of droughts and heat waves which is caused by global warming. Economic consequences on anthropogenic global warming won't be good. And these effects show one thing for the countries of the world: the economic consequences. The Hurricanes cause billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these. For many years the believers have argued about the causes of global warming. There has been a complicated problem because of the believers warn that the man made causes is left to advance to far .In fact for several years the earth temperature is rising. Now the question arises that what can we do to stop global warming. The simple solution to reduce global warming is to plan a tree which will absorb one ton of carbon dioxide over its life time, reduce wastage which cause green house gas emissions in one way or the other, try to share car which will reduce the usage of green house gases. Turing of the light when there is no use of it , chemicals which cause air pollution which is bad for the environment are carbon dioxide CO2 , sulfur dioxide, lead, nitrogen oxide.
