Earth surface is rapidly heating up. After 2000 the total seventeen warmest years have been recorded. Melting of the glacier, rising of sea levels, decrease in the forest, danger and scrambling of wildlife. The evidence that humans are causing climate change with drastic consequences for life on the planet is overwhelming. We can track all the above consequences to one common factor Global Warming. Global warming is termed as climate change by scientist. Although temperature rises in certain areas but the ocean current move the heat around in different parts of the globe. As a result of which some region experience cooler climate and some experience warmer climate.
Climate change encompasses not only rising average temperature but also extreme weather events, shifting wildlife population and habitats, rising seas and a range of other impacts. All of these changes are emerging as human continue to add heat-trapping greenhouse gases to the atmosphere.
According to researchers of WHO suggest global warming is the reason for around 150,000 death every year globally. Global Warming is responsible for the rise in temperature. Data from NOAA and NASA indicates that the year 2016 was the hottest year since the inception of climate record keeping from 1895. There has been an overall increase of 0.8 of over the stretch of 100 years.
Earth surface has the ability to absorb almost 75% of the entire solar energy. This is responsible for the increase in temperature. However part of energy is given back to the atmosphere in front of radiation. There are certain gases that have the ability to trap heat and restrict the heat from escaping from the atmosphere. There gases are know as greenhouse gases. Ozone, methane, carbon dioxide, chlorofluorocarbon etc are the example of greenhouses gases. These gases absorb heat and add to the process of heating of atmosphere thereby raising the temperature.
Greenhouse Effects and It’s Use
The question comes here is what is greenhouse effects? Was greenhouse effects always a bad? The answer for the second question is NO. It is useful in certain cases. There are certain places where the temperature is quite low. In some places green house room, glass surrounded room helps to grow vegetable, fruits and flowers. The energy from the sun enters the room. The room is made up of glass and it helps to retain the heat inside the room. Therefore, the solar energy helps in warming the soil and aiding in the plant growth and vegetation. However, the temperature of the outside will always be lower than the temperature inside the greenhouse. Moreover, the soil and plant release infrared radiation. Thus the glass reflects part of the energy and absorbs part of it. Green house effects helps in the sustenance of life and temperature. The atmosphere of the earth has a blanket of air which surrounds us just like the greenhouse room. The atmosphere has the ability to restrict the heat. Thus, it helps in keeping earth warm thereby maintaining temperature and sustenance of life.
The major gas that contributes to absorption of heat is carbon dioxide. Other greenhouse gases was methane, nitrous oxide, CFC’s and ozone. Initially the production of gases was within permissible quantity. Therefor, it was useful in maintaining the natural balance and life sustenance. However, the growing anthropogenic or human activities are constantly increasing the gases beyond the permissible limit.
Global warming is responsible for melting of glaciers, the rise in sea level, flooding of the coastal region and an overall increase in the temperature. The rise in temperature is also the reason behind increase incidence of diseases such as yellow fever, malaria, dengue among others. This is Greenhouse effects.
Greenhouse Effects on a large scale cause Global warming
we all know that earth is the only planet that can support and sustain life. Rest of the planet have extremely col or hot temperature. The presence of the thin atmospheric layer makes it possible to support life. The thin layer of the atmosphere contains greenhouse gases like CO2, water vapor, methane gas, nitro-us oxide, etc that has the ability to absorb sun rays and warm up the planet. This prevents the earth from becoming too cold. The absence of greenhouse effects will make the earth average temperature to be nearly 60 Fahrenheit, an extremely cold planet. Life would be impossible without the greenhouse effect. However, the concentration of greenhouse gas is on the rise since the 18th century.
At present, the carbon dioxide level is have increased almost to 40%. the levels of greenhouse gases are at its all-time high than the previous 650,000 years and are continuously rising. This is because the modern life and changes in the lifestyle of humans have led to constant release of heat-trapping gases or greenhouse gases. This is constantly warming up the atmosphere.
Therefore, this has started increasing the greenhouse gas to an unnatural level and significantly increasing the greenhouse effect. Thus, it is disturbing the environment and is altering the earth’s temperature.
Global warming Causes
The massive use of fossil fuels is obviously the first source of global warming, as burning coal, oil and gas produces carbon dioxide – the most important greenhouse gas in the atmosphere-as well as nitro-us oxide.
The exploitation of forest has a major role in climate change trees helps regulates the climate by absorbing CO2 from the atmosphere. When they are cut down, this positive effects is lost and the carbon stored in the trees is releases into the atmosphere.
Another cause of global warming is intensive farming, not only with the ever-increasing livestock, but also with plant protection products and fertilizers. In fact cattle and sheep produce large amounts of methane when digesting their food, while fertilizers produce nitrous oxide emissions.
Waste management methods like landfills and incineration emit greenhouse and toxic gases – including methane – that are released into the atmosphere, soil and waterways, contributing to the increase of the greenhouse effects.
Modern life is highly dependent on the mining and metallurgical industry. Metals and minerals are the raw materials used in the construction, transportation and manufacturing of goods. From extraction to delivery, this market accounts for 5% of all greenhouses gas emissions.
Global Warming Effects
Increase of temperature and the climate upheavals disturb the ecosystem, modify the condition and cycles of plant reproduction. The scarcity of resources and climate change are changing life habits and migratory cycles of animals. There are many species-including endemic species-or conversely, the intrusion of invasive species that threaten crops and other animals which disappeared.
Global warming impacts on biodiversity. It is the balance of biodiversity that is modified and threatened. According to the IPCC, a 1.5° C (34.7° F) average rise might put 20-30% of species at risk of extinction. If the planet warms by more than 2° C, most ecosystems will struggle.
Because of global warming, permafrost and ice are melting massively at the poles, increasing the sea level at a rate never known before. In a century, the increase reaches 18 cm. The worst case scenario is a rise of up to 1m by 2100. The acidification of ocean is also a great concern. Large amount of CO2 captured by the oceans makes them more acidic, arousing serious questions about the adaptability of seashells or coral reefs.
Human being are not spared by these upheavals. Climate change is affecting the global economy. It’s shaking up social, health and geopolitical balances in many parts of the world. With the scarcity of resources like food and energy give rise to new conflicts. Rising sea levels and floods are causing people to migration. Small islands state are in the front line. The estimated number of climate refugees by 2050 is 250 million people.
Meteorologists and climatologists around the world have been watching the effects of global warming on the weather phenomena and the impact is huge, more drought and heatwaves, more precipitation, more natural disaster like floods, hurricanes, storms and wildfires, frost-free season, etc.
Solution from Global Warming
There are some ways by which we can reduce the Global Warming.
To prevent climate change is to move away from fossil fuels. What are the alternatives? Renewable energies like solar wind, biomass and geothermal.
Reducing our consumption of energy and water by using more efficient devices (ex: LED light bulbs, innovating shower system) is less costly and equally.
By using electric and hydrogen mobility transport can definitely help to reduce CO2 emissions and thus fight Global Warming.
Build new low energy building and to renovate the existing constructions – In reducing the CO2 emissions from building caused by heating, air condition, hot water or lighting.
Encouraging the better use of natural resources, stopping massive deforestation as well as making agriculture greener and more efficient should also be a priority.
