The warming also increases the water-holding capacity of the atmosphere. Thomas R, Karl explains that the increased availability of water vapor in the atmosphere also leads to a significant increase in the energy available to drive storms and associated weather fronts, therefore affecting rainfall rates, precipitation amounts, storm intensity, and related runoff. (Karl, Tomas). The loss of Brazils rainforests also causes heavier rainfall and stronger storms in various parts of the world. Since the world climate and weather are generally dependent on the sun heating the surface of the earth, the reduction of rainforest canopies naturally causes major changes in the usual weather patterns. First, with the absence of vegetative covers, the sun directly heats the soil, which reflects solar radiation back to the atmosphere, but with the presence of greenhouse gases, the heat is simply trapped in the atmosphere. According to one worst-case scenario, the temperature would rise by 5. 8 C, which could lead to irreversible changes in ecosystems, a negative impact on the global environment, and a significant sea-level rise causing floods and widespread damage to human society through destruction of human settlements and infrastructures, as well as economic instability and massive food insecurity. (The Kyoto Protocol) The ACIA report was not all bad news, however.
There will be new opportunities too, Paul Prestrud, vice chair of the ACIA, told The Philadelphia Inquirer. The report noted that fisheries would be more productive with shorter winters. Less ice would make it easier for ships to navigate the Northwest Passage and other treacherous sea routes. And oil companies would have easier access to oil and gas deposits beneath the Arctic tundra.
Still, for many scientists, the good produced by global warming doesnt outweigh the bad. Susan Joy Hassol, the author of the ACIA report, told National Geographic that global warming must be slowed. A climate system is like a supertanker; you cant turn on a dime, so you have to turn the wheel now to avoid that iceberg ahead. In an effort to curb activities that emit the pollutants suspected to be behind the warming trend, representatives from 160 nations agreed on the Kyoto Protocol last December. Named for the Japanese city in which it was completed, it would require 39 industrial nations to stabilize emissions of gases like methane below 1990 levels by 2012. The other 121 nations - including most of the less developed countries, many of which argue that they should be allowed to strengthen their economy before imposing pollution controls - are so far exempt from regulation. (McNally) Conclusion Global warming, of course, does have its own unexpected aspects.
Arctic sea ice, it seems, is in a delicate climatic balance already. Global warming could lead to its complete disappearance, at least seasonally, and certainly can be expected to cause substantial reductions at the southern margin. Scientists cannot see the future and therefore can only speculate on what the effects of global warming will be tomorrow. Yet, it is a known fact throughout the scientific community that global warming is going to get a lot worse if our attitudes are not changed about the environment.
