Threat of Global Warming BR> :It is true, “Global Warming is real”. In 1986, a panel of 150 scientists
from eleven countries issued a report warning that human activities such as automobile use, the production of energy from burning fossil fuels, and deforestation could cause global temperatures to rise by intensifying the earth’s greenhouse effect. But it didn’t capture the world’s attention until 1988. It was warned that continuous rise in
temperature would cause catastrophic climate changes that would adversely affect the environment and human health. Various adverse effects have been witnessed to by humankind since then- high intensity storms, heat waves, rise in sea level, record-setting drought and many other catastrophes. The change in temperature also brought about adverse change in the ecology. In this paper I have concentrated on the effects of Global Warming on various species on land, both animals and birds. I have concentrated on the causes behind these adverse effects, and tried to gauge the threat of Global warming. Then I moved on to discuss about the step taken by the International community, the Kyoto Protocol, and why it is not a success. And at last I talked of the hope which is still alive among certain community of people. Some climatologists maintain that the higher incidence of severe
weather during the 1990s was not necessarily linked to higher greenhouse gas levels or higher global temperatures. Moreover, as several researchers point out, the IPCC’s predictions about global warming are largely based on computer-generated climate simulations, which have proved to be unreliable. Global temperature readings taken on the ground, from satellites, and from weather balloons often contradict the projections of the computer simulations. For example, no warming of the lower troposphere (the atmosphere between 5,000 and 28,000 feet) has been recorded, even though climate simulators indicated that tropospheric warming should have already occurred due to increased carbon dioxide levels. Skeptical scientists contend that the fallibility of the IPCC’s predictions raises serious doubts about the projected severity of global warming. Some researchers are even more optimistic, maintaining that a warmer earth will result in lusher forests, increased food production, lower energy costs, and improved human health. Many scientists and environmentalists, however, fear that unchecked global warming will lead to dramatic increases in extreme weather that could uproot regional populations, augment the spread of infectious diseases, and disrupt worldwide economies. In my opinion, Global warming should be controlled, if not stopped. The initiative should come from the developed countries and countries with well established industrial sector. If not, the threat of Global Warming will be the cause of the extinction of life form from the face of Earth.
