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.
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.
Excess of greenhouse gases in the atmosphere is harmful to the environment because it causes global warming, increases the acidity of the ocean, and depletes the ozone layer. First of all, greenhouse gases are harmful to the environment because it is the main reason why global warming is occurring. Global warming has been a major problem for years. When the Sun’s heat reaches Earth, some of the heat bounces back into
Secondly, the water from melting glaciers and the ice sheets of Greenland and the Antarctica would also add water to the ocean which cause negative consequences to human and other habitat. The Earth's average sea level was predicted to be increase by 0.09 to 0.88 m between 1990 and 2100. Besides, one of the impact of greenhouse effects is ocean acidification. The oceans provide extraordinary ecosystem services to societies, food, regulation services (carbon absorption), cultural and recreation as well as nutrient
Ways it can affect people is when it when wildfires start and the animals or who ever is in that place couldn’t escape and the species with their habitat could be destroyed. Also Melting tundra, rising sea levels is a threat to people who live near the ocean since flooding and tsunami could happen. We all know that tsunami can kill over thousands of people.. Another negative effects climate change that scientists discovered is that the ice is breaking up way too early, and that the plants and animal ranges have shifted. Also, they discovered trees are flowering sooner. Last, there is the loss of sea ice and the more intense heat waves.= which can be a problem in the future.
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.
This causes fluctuations in the temperature, causing climate change. The increase in the greenhouse gasses causes less heat to be radiated back into space. This is called the enhanced greenhouse effect. The Enhanced Greenhouse Effect is when there is an increase in the concentration of carbon dioxide and other greenhouse gasses, this would decrease the amount of energy escaping from the earth back to space hence heating up the earth. The upward and downward equilibrium is disturbed leading to global warming and rise in temperatures.
For example, the greenhouse effect contributes to global warming causing the polar ice caps to melt, which increases the sea levels and causes floods. Greenhouse gasses also alter the weather, as when the temperature increases, evaporation of water does as well. This leads to an increase in rainfall and dry soil due to evaporation, both of which negatively impact agriculture, due to lack of ideal soil and an excess amount of rain, which negatively affects the yield of vegetation. As the concern about greenhouse gases, or rather carbon dioxide increases, so does the urgency to find a method to reduce the CO2 emissions. Fortunately a method, Geosequestration or Carbon Capture and Storage (CCS), has been discovered and is said to be a promising method for reducing the amount of CO2 being emitted.
In the atmosphere, naturally occurring greenhouse gases trap the radiation in a ‘blanket like effect’. These gases include carbon dioxide, water vapour, nitrous oxide and methane, among others. This helps to stabilize the average temperature of approximately 15 degrees Celsius on Earth. Excess greenhouse gases results in more heat being trapped in the atmosphere. (WWF, 2014) At current, there is an excess amount of greenhouse gases and the earth is warming at rapid rates.
