This change is alarming rapid in nature. Global sea level rose considerably and might even double in the next coming years. Disturbingly, other observable changes are rising global temperature, warming oceans, shrinking ice sheets, declining arctic sea ice, glacial retreat, extreme events, ocean acidification, and decreased snow cover. These pressing issues have to be addressed holistically right away. In order to better understand how countries could work hand in hand to look into the issues of climate change, its long-term adverse effects worldwide, and the possible solutions, it is inevitable to analyze it using theories concerning international relations which are defined as an interdisciplinary academic field similar to global studies or an entirely independent academic
These gases are believed to be the main cause of climate change. The three most well known greenhouse gases are CO2, CH4 and N2O. The concentrations of these gases in the atmosphere have increased drastically since the pre-industrial times. It is well documented that the increase in concentrations of these gases is caused by anthropogenic activities that includes the use of fossil fuels as well as agriculture. Apart from the atmosphere, the hydrosphere is also affected by this abnormal change in the concentrations of the mentioned gases.
The signs that climate change affects our one and only earth clearly show up in the oceans and atmosphere. A place where climate change is most notable is in the sea levels. Over the past years sea level has risen so much that it has caused damage to ecosystems. “Sea level rise is caused primarily by two factors, related to global warming: the added water from melting ice sheets and glaciers and the expansion of sea water as it warms”(Understanding, 2016). This is concerning because the areas living near or below sea level can one day, in the near future, be underwater.
The increasing in the frequency and severity of extreme weather events could increase the risk of dangerous floods, stronger earthquakes, typhoons and other direct threats to people and property as well as the concentrations of unhealthy air and water pollutants. Climate change has caused global warming and rising sea levels, which could lead to the destruction of the Earth 's civilization, affect directly our food supplies, water resources, human health as well
The degree of natural disasters between different countries and regions also lead the different social changes between the countries. The shift from collecting, hunting and fishing to agriculture may have happened because, in some areas, the human population grew too large to be sustained by existing resources. 5. Economic & political advantage International shifts in economic or political advantage also have great impacts on social change. For example, ‘Globalisation’ & ‘the WTO’ are key factors in our modern society affecting the global economy, political structures and dynamics, culture, poverty, the environment, gender etc.
According to (climate change. (n.d.). Dictionary.com Unabridged. Retrieved February 25, 2016 from Dictionary.com website), climate change also means a long-term change in the earth’s climate especially a change due to an increase in the average atmospheric temperature. It is rather obvious that the main culprits behind this phenomenon are earning tons of millions.
Climate change is a change in global or regional weather in a long period of time. I believe the climate change is the biggest problem because it has done lots terrible impacts to the earth. Now the global warming is happening. From the 1900 to 2000 the global temperature has increased about 0.54 Celsius degrees and it is causing the melting of ice in North Pole and South Pole. Then the chain reaction is beginning.
According to the United Nations Industrial Development Organization (UNIDO), climate change is likely to have a greater impact on India compared to other countries similarly positioned, on account of the unique combination of its geography, diverse population characteristics and extremely high carbon-related energy dependence. The question is, how will the changing climate affect our health? Climate change can have both direct and indirect human health impacts. Indirect impacts arise from changes in temperature patterns, which may disturb natural ecosystems, change the ecology of infectious diseases, harm agriculture and fresh water supplies, exacerbate air pollution levels, and cause large-scale reorganization of plant and animal communities.
The global average temperature increased by about 0.8°C from 2005, but the current warming trend is 0.13 – 0.16 °C per decade, and it is projected to continue to rise at a rapid rate (Hansen et al.2010). The effect of the activities of man especially in technologically advanced nations, has brought about emission of CO2 and other greenhouse gases which has resulted in the depletion of the ozone layer and global warming (Hegerl et al., 1997; Tett et al., 1999, 2002; Stott et al., 2000).These can be seen from the changes in meteorological parameters such as temperature and precipitation.
The greenhouse gas emissions from human activities are driving climate change and they continue to rise. What we must be aware of the fact that they are now at their highest levels in history. Climate change also hit economy of the world. Damage to property and infrastructure during disasters such as sea-level rise, wildfires and extreme storms require expensive repair. Tourism and hospitality industries are affected.
