Global Warming, Climate Change and Greenhouse Effect - A Storm in a Teacup

The hustle and bustle about climate change is getting louder and louder with the passing of every single month, probably day. The rate at which the planet earth is experiencing climate change is truly making things really horrible. Specifically, the level of carbon dioxide that is increasing in the atmosphere is really a threatening situation. 

 

The pace at which the ice bergs are melting is making the sea levels rising, and that is why, the weather patterns have been changing at such a fast rate thus making the sea levels is higher. Moreover, we can also experience water deficiency and probably face more hazardous disasters such as typhoons, cyclones and hurricanes at a faster rate. Moreover, the horrible environmental factors have also created so many issues and thus, deserts may also expand and will ultimately decrease the amount being grown on the soil. 

Moreover, some of the scientists are also claiming that the earth is suffering due to the global warming and that is why, precautionary measures should be adopted as far as making earth a safest place. Innumerable scientists across the globe are working hard to find out the scientific aspects of climate change and also working on finding an appropriate solution to this problem. 

If we have a look at the natural climatic cycles, we will be amazed to see that abrupt changes are taking place and which is not a normal thing at all. Something that is really scary is the burning fossil fuels that are emitting greenhouse gases at a hazardous level. That is why, we can say that everything i.e., Global Warming, Greenhouse Effect, and above all Climate Change are happening at a very fast pace.

Moreover, the rate at which the climate change is happening compels us to shift our policies in every aspect according to the change and that is the only way, we can save our planets from various hazards.

Effects Of Global Warming On Human Health

Global warming is a globally recognized issue that has risen due to the emission of greenhouse gasses from man-made resources.  The rise in the earth’s temperature is continuous and it is expected to be more in the future coming years. The increasing global warming is affecting every life form on the Earth.  Due to global warming rivers are drying, waste glaciers are melting, green land is turning into barren lands, and dead seas or hypoxic seas are becoming common.  Due to climatic change there is no doubt some positive aspects seen on the earth like less intense winter in some local areas, besides there has become positive agricultural production seen in some cold areas where there was no food and crop production due to intense winter, but it, on the other hand, is rendering great loss to the health of human being and its food cultivation  

Respiratory And Cardiovascular Diseases:

Due to the high temperature, the volume of hydrocarbon and other pollutant gasses upsurge in the air that in turns cause the people to become the victim of cardiovascular diseases. The smog and other pollutants in the air directly cause respiratory disorders and cardiovascular diseases. Aeroallergen and the pollen at high and dry temperature trigger the attack of asthma in more than 3000million people annually.

Natural Disasters:

The change in temperature also has impacts on the geographical and physical condition of the earth. It has caused irregular rainfall pattern, drought in some part of the earth.  The severe drought and lack of rain in some areas lead to the freshwater crisis and loss of vegetation in some areas. The unusual rain pattern causes the world to encounter great disaster in the form of the tsunami, flood storm, and hurricanes which cause the loss of human life and valuable cattle; it also results in the loss of vegetation. Flood and disaster give birth to fatal epidemic diseases and several water-borne diseases that make a lot of people lose their life.

Global Warming Causes Vector-Borne Disease 

Global warming is also giving birth to many fatal diseases and also importing vector-borne diseases due to transmission of season and alternation of the geographical range of the planet earth.

Skin Ailments:

Ultraviolet radiations emitted by the sun are very harmful to human skin. The ozone layer protects the earth and its inhabitants from these harmful rays. Due to the global warming ozone layer is being destroyed perpetually and the ultraviolet radiation gets their direct exposure to the earth and its life from. The rays cause many skin diseases in a human being.  Direct exposure of the rays on the human skin causes skin cancer beside other skin complications.

Loss Of Human Vegetation  

The severe temperature has also led to the generation and introduction of non-friendly soil bacteria and pesticides invasions on the agricultural sites, the introduction of such foreign species in vegetation regions have led to the destruction of vegetation and crops. 

Serious and necessary steps should be taken by the entire globe’s states and individual to protect the earth from the increasing global warming and its increasing harmful effects. Carbon dioxide and other greenhouse gasses emitting vehicles, machines and industries should be diminished or at least lessened. More trees should be planted to make the environment purified from the carbon dioxide and other greenhouse gasses

Major Environmental Issues Of Pakistan

The environment of the world is getting degraded day by day with the passage of time. The degradation of environment and the environmental concerns   have become yellow peril for the whole of the world. The concerns are getting more catastrophic due to their effects on the lives of the organisms and human living in it. The environmental concerns are adopting the acute shape due to their increasing drawbacks on the environment and its habitat. Rapid economic and industrial development along with the increase in human population is the core reasons behind the evolution of ecological problems.

Some effects of environmental concerns:

Pakistan is right now confronting many challenging environmental issues that need to be sort out at the first priority air pollution is the most important concern of this era. The rapid increase in the numbering of automobiles on urban roads and the gas emitted from the industries and plants of Pakistan is the main cause of air pollution. The air pollution is much responsible for causing many chronic bronchi ailments in human beings. Secondly, the hazardous pollutant in air mixes up with the rain causing clouds and fall on the earth in the form of acidic air. The acidic air causes hazardous effects on the human beings animals and plants on the earth

Water pollution:

The water pollution is another factor creating serious ecological concern. The water reservoirs in Pakistan are mostly contaminated with the sewerage waste water discarded from the industries and agricultural sites. This contaminated water is consumed by the half of the population the toxic water is responsible for causing serious ailment to the consumers of the water. Besides the poor sewerage system also contribute to contamination of water in urban areas of Pakistan.

Deforestation:

Cutting of forests to construct the roads and residential areas have destroyed the natural environmental health in the country. A policy was presented by the government in 1992, which declared to ban the forest cutting but nothing profound was brought by the policy. Strict and strong legislation should be planned by the government to ensure sustainable harvesting of forest in the country. Secondly, a strategy for carbon financing should be developed at policy level with the motto we value the trees because tree and plantation absorb carbon dioxide from the air. The developing countries will provide the financial aid to support the cause what will be the utter requirement for this cause is that we government will need to ensure the capital comes in and is used straightforwardly for the cause.

Plantation of trees in urban areas:

Urban cities are most populated. Trees in cities absorb carbon dioxide causing the air to get purified. So plantation of new trees is essentially required for the atmosphere. Trees are planted in urban areas, but new trees are to be planted more. Besides, man-made forests like Change Mange ought to be constructed as well.

Pollution from factories:

The waste and toxic material discarded from the factories is the most concerning issue for the Pakistani authorities the waste material is wiped into the rivers causing the marine life to become extinct.  Besides, it pollutes the water in ponds and lakes which directly affects the water consuming bodies near the reservoir of the water. The waste material discarded by the factories is drained into the land area the chemical components in the matter reacts with the soil of the land making the soil erosion and the land deserted.

Climatic change in Pakistan:

The climate condition in Pakistan is continuously changing. Due to global warming, the glaciers in the Himalayan mountain range and Karakorum mountain range is continuously melting causing the floods and unusual rain in Pakistan this subsequently is destroying the crops and cattle in the country. Besides due to global warming the average temperature in the tropical area is also rising annually which will consequently result in less production of crops.

Destruction Of Ozone ( Ozone Depletion)

Ozone is layer of oxygen found in the upper layer of atmosphere (stratosphere) to protect Earth from the harm full effects of ultraviolet radiation.  Ozone consist of 3 oxygen molecules rather than 2 and it is highly .But its presence in the troposphere (the lower layer of atmosphere) causes effects to human and plants living on the earth in the form of diseases due to its highly oxidizing ability.

How ozone is produced:

Ozone is formed in atmosphere by the reaction of ultraviolet radiation with the oxygen molecule that comprises 21% of the atmosphere. The ultraviolet radiation entering the atmosphere breaks apart the oxygen molecules (O2) to produce two oxygen atoms. These single highly reactive oxygen atoms then combine separately with the oxygen molecules to make the ozone (O3) molecules. This reaction take places in the stratosphere where there are continuously ultraviolet radiation coming in. Ozone reacts with the sunlight and hazardous human produces hydro carbons and nitrogen gases continuously, resulting in the production of and destruction of ozone layers. In troposphere region, ozone is produces by the reaction of pollutant gases and natural gases with ozone in the presence of sunlight. The burning of fossils fuels contribute a lot in the production of ozone troposphere. The ozone produces in comparatively quite much less as compared to the ozone prepared in stratosphere and also can’t reach to the stratosphere to meet the need of ozone required there the plants and  the troposphere ozone is also destroyed when it reacts chemically with soil and plant on the surface  of earth

 

Effects of ozone depletion:

Since the advent of universe, the ozone has been protecting the earth from the harm full radiation of UV rays. It has become the great concern by the scientist and environmentalist since 1970. Ozone layer is depleted by the harmful gases .chlorine and bromine gases destroy the ozone layer in the upper stratosphere. But 80 percent of the ozone layer is destroyed by the chlorofluorocarbons emitted from the human made gas emitting sources.  The   chlorofluorocarbon sand   volatile organic gases that are released from refrigerators and other vehicles factories destroys the ozone layer.  These gases remain stable in the lower atmosphere of air but when they reach the stratosphere. They react with the harmful ultra violet rays and emit the chlorine atom that reacts with the ozone oxygen causing the depletion of ozone layer.

Effects of ozone depletion:

Breakage of ozone layer has adverse effects on the environment.  Depletion of ozone layer provides the path to ultraviolet rays to reach the earth, the ultraviolet rays is interlinked to cause various health and environmental issues.  Direct exposure of Ultraviolet rays cause several type of skin and eye diseases. The radiation accelerates the skin aging problem. It weakens the human immune system. UV rays damages the other amphibian species UV is home how responsible in decline of the number of amphibian species on the earth. UV destroys the plankton's that are essential to maintain the food chain and carbon cycle of marine ecosystem.

Decrease of ozone in stratosphere cause the increase of ozone in the troposphere. Ozone gas present in stratosphere is referred as green gas that causes the temperature of earth to rise and cause the climate to change.

Global Warming Is A Global Threat

The earth’s temperature is rising day by day; massive glaciers are melting; plain land is converting to seas and ocean and surface of the sea is rising abruptly to an alarming extent. What’s the deal??? Scientist claims it to be the result of Global warming. Now the question is; what is global warming??? 

 

Global warming is an abrupt increase in temperature of Earth due to an emission of the Greenhouses gases in the atmosphere. Carbon dioxide gas emitted in greenhouse effect is the most responsible element in causing the global warming. Methane gas causes 20% of the greenhouse effect. The greenhouse effect occurs naturally to some extents to keep the earth’s habitable condition necessarily warm enough for the life existence. But since the beginning of the revolutionary industrial world, the ratio of carbon dioxide and the methane gas in the Earth’s atmosphere has risen high, resulting in the increase of the world’s average temperature.

 

 Factors contributing in global warming:

With the rise of urban life, burning of the fuels of the vehicle and factories and deforestation has contributed a lot in global warming by emitting the dangerous gases. This created the disastrous   Impact on the ecosystem in the form of storms; floods, tsunami, and drought etc. The carbon dioxide gas in the atmosphere causes more evaporation of the water. Water vapor already being the greenhouse gas accelerates the warming and makes more water vapors to evaporate, leading to an immense rise in the temperature. This rise in the temperature causes vast glaciers of the world to melt and subsequently cause the floods, irregular rainfall and cyclones. It has been seen that due to global warming, glaciers considered as permanent glaciers have also started to melt.

 

Major concerns of global warming:

Global warming is also causing the sea level to rise high up and it’s a major concern for ecologists. Major common concerns are as discussed below.

Rise in sea level:

Due to irregular rain pattern and melting of ice glaciers, many cities in the coastal areas are on the brink of getting submerged under the sea. And many islands are supposed to become completely vanished from the earth’s surface in near future.

 

Health disease and malnutrition:

A rise in temperature leads to airborne disease. Besides, the ultraviolet radiation due to global warming is causing many skin diseases at the other place. Secondly, severe sort of drought has become frequent and the starvation is also a concerning phenomenon in many countries of the world due to global warming.

 

Poor farming:

The unusual changes in the temperature also have adverse effects on the world’s agriculture and crops.

How to control global warming:

The increasing threats caused by global warming have forced the entire world to chalk out plans and actions to avert the coming threats. States have designed laws to prevent the deforestation. But, more is needed to do. More trees should be planted; recycle or renewable products should be used. Thermal power should be used for generating electricity. Transportation should be shared to reduce the emission of greenhouse gases. We should promote Eco-friendly-technologies as a replacement of greenhouse gas emitting technologies; painting the roof-top and road in white can also contribute in reducing the global effects. By our individual and mutual cooperation on the massive scale, we can reduce the global warming that is an alarming issue for the whole ecosystem.
