“Climate change meaning, implications, suggested solutions”
Pakistan Muhammad Amir(24/Male)
Meaning: Scientists agree that the world is heating up. Global warming describes the Green House effect. Certain gases allow short wave radiation from the sun to pass through them and while also absorbing some long wave radiation that gets reflected back into space. Green House gases trap heat the way glass walls of a Green House do. They include Methane and Nitrous Oxide but the paramount culprit is Carbon Dioxide. It significantly enhances the absorption and conversion of sunlight energy into heat.
Implications: For thousands of years emissions of the green house gases to the atmosphere have been well balanced by the amount of green house gases that get naturally absorbed. These conditions have allowed human civilization to develop within a consistent climate. Photosynthesis enriches the planet with oxygen as plants suck up Carbon Dioxide from the air. Special clay minerals have also absorbed oxygen contaminated compounds into the sea floor. Volcanic eruptions emit particles that hold the earth surface but only briefly. Evidence shows that human activity contributes to global warming by adding to and changing the levels of the gases responsible for the green house effect. Changes that have historically taken thousands of years are now happening over the course of decades which can exacerbate the risk of disasters. Floods and storms can erode the community which need to prepare and respond to successive hazards.
The temperatures have been increased and dropped worldwide. About 5 degrees Fahrenheit have been dropped over Asia, North America and northern Europe while increased by 4 degrees Fahrenheit in Australia, South America, and southern Africa. Sometimes winter storms and winds intensify the potentially dire consequences of the impact of abrupt climate change. Water vapors trap heat and as a result increase the surface air temperature.
Glaciers worldwide have been found shrinking significantly like in Alaska, the Himalayas, the Antarctic and high tropical mountains show that the global snow cover is decreasing and that massive glaciers worldwide are disappearing fast. Water flows to the seas from glaciers and ice caps. In oceans the water warms and expands. The sea populated cities like Tokyo, Shanghai, Bangkok and New York are all at risk. Scientists predict that floods and rains are likely to increase in number in severity. Climate related diseases like Malaria can surge. Other signs of climate change are seen in drying forests and dying wild life.
First of all we have to admit that we have a problem of climate change and global warming. We are continuously changing the atmosphere of our planet through our improved lifestyle, use of fossil fuels and ignorance to the amount of Carbon Dioxide being released into the atmosphere. Consumption of energy from fossil fuels results in emission of Carbon Dioxide therefore in order to take our first step in reducing the bad effect of climate change in our life is trying to reduce emission of harmful gases into the atmosphere and try our level best not to disturb the balance of greenhouse gases.
*Reducing the threat of global climate change starts with harnessing technologies and resources to lower greenhouse gas emissions and using clean energy options where available, such as solar and wave power.
*We can reduce the threat of climate change by using fuel efficient vehicles which can use less amount of fuel.
*Everybody is aware about the advantages of walking and bicycling not only they can reduce the chances of heart attack and prevent us from heart diseases but can help us to reduce the emission of Carbon Dioxide in the atmosphere.
*A well maintained vehicle is more fuel efficient and reliable which can reduce the amount of Carbon Dioxide being emitted in the atmosphere. It can also increase the life of the car.
*Smart driving can reduce the emission of gases as aggressive driving and excessive use of brakes wastes gases.
*Trees help us reducing the amount of Carbon Dioxide by absorbing CO2 and give off oxygen. A single tree will absorb approximately one ton of carbon dioxide during its lifetime, which is more than enough. Therefore, we should accelerate reforestation which can reduce soil erosion, moderate the temperature and preserve endangered wild species. Avoid use of chemical fertilizers or pesticides on plants. Recycling of all materials can reduce the solid and toxic wastes.
Awareness about emission of CO2 and abovementioned few steps could make a big difference in reducing emission of Carbon Dioxide and climate change. It is very essential to share information about recycling and energy conservation with our relatives, friends, neighbours and others and to encourage public officials to take all the initiatives that are good for the environment. Without disrupting our life style, it is a “WIN-WIN” situation with massive reduction in air pollution having no economic disruption.
