Already, weather patterns have changed as ice caps and glaciers have shrunk, increasing the likelihood of rising sea levels; plant and animal ranges have shifted; and with all this, comes the adverse impact on agriculture. The loss of polar regions is partially responsible for these effects. The dark, open waters are exposed to absorb most of the solar energy and in doing so, a recipe for more and faster global warming is created. A vicious cycle of ice loss it set off and so is the further warming of the ocean surface, which will in turn result in more ice loss. This melting ice is being released into the oceans and causing sea levels to rise.
As a result, heat from the sun is trapped in the atmosphere and making the planet really hot. Since 1880, the global temperature has been increasing. Many people know that the Earth is warming due to the greenhouse gases, and this is true. Although global warming increases the temperature of Earth’s surface, global warming does more apart from warming the Earth’s surface. It changes the climate, raises the sea level, affects the nutrition of plants, and causes more extreme weather.
Also, the higher sea temperatures are causing the ice shelves that jet out from Antarctica to weaken and break off since they are being melted from below. In addition to the melting land ice, thermal expansion is another factor that is causing our sea levels to rise. About half of the century’s rise in sea level is due to the fact that the warmer oceans are expanding and taking up more space. The annual rate of rise over the past twenty years has been around 0.13 inches a year, which is twice the average speed of the previous years. It is said that the oceans can potentially rise by 11 to 38 inches by the year 2100.
When radiant energy from the sun emits heat onto earth, it passes through the atmosphere. In the atmosphere the greenhouse gases trap infrared photons, causing the earth to increase in temperature. As a result of technological advances, the problem has increased because more fossil fuels are being burnt than previously, increasing global warming. This problem started in the 19th century during the industrial revolution, when fossil fuels started being released into the atmosphere more frequently due to human activity. (Columbia.edu, 2014) If this continues arctic ice will melt, sea levels will rise which will resulting in flooding in parts of the world, and weather patterns will change.
Question: Discuss about global warming and its impact on developing and developed country. Answer: Global warming refers to the increase the average surface temperature of Earth due to effect of greenhouse gases, such as carbon dioxide which is caused due to burning of fossil fuels or from deforestation. The increase in carbon dioxide leads to melting of polar ice caps which increases the sea level and pose danger for the people. The amount of heat which is trapped in the atmosphere depends upon the concentration of greenhouse gases and the time they stay in the atmosphere. The major greenhouse gases are carbon dioxide, methane, ozone, nitrous oxide and water vapour.
These activities includes burning oil, coal and gas thus releasing CO2 into the atmosphere. There are farming practices and land-use changes that increases the amounts of methane and nitrous oxide that’s being released. Factories produces long-lasting greenhouse gases that does not occur naturally in the environment. Deforestation contributes to the greenhouse effect as the trees that are being removed has a critical role by using the CO2 and release oxygen in the process which can form a balance in the atmosphere. Another factor is population growth, because more people will use fossil fuels for heat, manufacturing and transportation and this will just increase the amount of greenhouse gases in the atmosphere (West,
The rising temperatures due to climate change in the atmosphere are causing the ocean’s temperature to increase, therefore, the ocean temperatures are becoming too warm and result in catastrophic hurricanes. Another factor is that warm air holds more water vapor than cold air. “The rising air temperatures since the 1970s have caused the atmospheric water vapor content to rise as well. This increased moisture provides additional fuel for hurricanes” (Hurricanes and Climate Change). The excess moisture that is held in the atmosphere is causing the hurricanes to grow larger and quicker in pace.
The Main Greenhouse Gasses • Water vapor (H2O) • Carbon dioxide (CO2) • Methane (CH4) • Nitrous oxide (N2O) • Ozone (O3) • Chlorofluorocarbons (CFCs) Explaining Greenhouse gasses, Greenhouse Effect and Global Warming Greenhouse gasses are the gasses that absorb Infrared (IR) radiation in the atmosphere. These Greenhouse gasses contribute to the Greenhouse Effect and the Greenhouse Effect is one of the main causes for Global Warming. What is global warming? Global warming is when the Earth’s temperature rises above the normal, due to too many greenhouse gasses in the Earth’s atmosphere, trapping an abnormal amount of heat. The amount of greenhouse gasses has increased gradually in recent times.
The greenhouse effect is a heating occurrence in the Earth’s atmosphere. In which the Earth experiences a temperature increase due to certain gases released in the atmosphere (water vapour, carbon dioxide, nitrous oxide, and methane).The Greenhouse effect seems to be the main cause of the current global warming trend. This is due to the trapping of heat in the Earth’s atmosphere that’s radiating towards space. Where do the Greenhouse gases come from? Quite a crucial component of Greenhouse gas is carbon dioxide (CO2).
Humans do things that create carbon dioxide which is one of the greenhouse gases that cause the greenhouse effect. The greenhouse effect is when gases like carbon dioxide become trapped in the atmosphere and trap incoming solar energy. That solar energy is then redirected in all directions thus, warming the entire planet and causing what we know as global warming. Global warming is a heating up all parts of the planet causing global climate changes. “A major international assessment of climate change…provides conclusive new scientific evidence that human activities are causing unprecedented changes in the Earth’s climate.” (IPCC Confirms, 2013).
