Challenge of Climate Change
Joint effort imperative
Melting of polar ice due to global warming leads to sea level rise
The international communities unanimously came to an agreement for a legal obligatory contract in Kyoto of Japan in 1997 as to who would reduce up to what quantity of their green house gas emission. But in reality, even after having accepted all conditions, the industrially developed countries are unsuccessful to a considerable extent in fulfilling their promise till today. The anxiety about this is that the United States who is responsible for 20 percent of greenhouse gas emission has not yet signed the Kyoto protocol. With it there is also Australia. But the hope is that many states of the United States have taken different steps to reduce the greenhouse gas on non-governmental initiative. Scientists believe that having 1990 as the foundation year 5 percent reduction is not sufficient. The emission needs to be reduced by 50 percent. If this can be done, then only the stability will come to the atmosphere. In the meantime positive change has began in Europe. The European Union has taken a plan for reducing it 20 percent by 2020. Natural calamities of different phenomenon has increased as a result of climate change. The extent of storm, cyclone, drought etc. has increased considerably. Enormous amount of wealth and lives has been destroyed. If this rate of the climate effect continued, the extent of loss will vehemently increase. Then by 2020 the major coral reef will be discoloured. The rate of death will increase due to heat, flood and draught. The visible change for the change of the climate is very dreadful. The overage temperature of the world since the middle of the 18th century has increased at 0.6 degree Centigrade. The changes which occurred as a result of the change of the climate in the present century are as the following: * The average height of the surface of the sea has increased by 10-20 cm. * Nearly two-thirds of the total area of the condensed iceberg of Switzerland has reduced. * Almost 40 percent of the summer ice plating in the polar region has reduced. * 92 percent of the ice of the Nigerian mountains is lost and 82 percent is lost from Kilimanjaro. * 40-60 percent of the total quantity of water is reduced from the large larches of the Niger, the Chad Lake and the Senegal rivers. * 30 percent of the production of crops in South Asia shall be reduced within 2050 as a result of climate change and rapid insufficiency of water shall occur in West Africa. * The affliction of cholera shall increase rapidly in South Asia for the rise of heat in the costal larches. * The mangrove forests of nearly 2500 square kilometers of Asia shall extinguish if the sea level rises up one meter more. * Bangladesh's sustenance of loss shall be the highest for nearly 20 percent of the land shall merge into the sea. To restrain change of climate and create a balanced environment, co-operation between the northern and southern countries is an imperative. Multiple tasks are depending on the developed world. Joint and combined ventures are necessary to meet the future challenges of climate change.
