Global Warming

Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.This hurts many people, animals, and plants. Many cannot take the change, so they die.

The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere.As a result, the temperature rises.

1. Polar ice caps melting The ice caps melting is a four-pronged danger. First, it will raise sea levels. There are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 230 feet. Luckily, that’s not going to happen all in one go! But sea levels will rise. Second, melting ice caps will throw the global ecosystem out of balance. The ice caps are fresh water, and when they melt they will desalinate the ocean, or in plain English - make it less salty. The desalinization of the gulf current will "screw up" ocean currents, which regulate temperatures. The stream shutdown or irregularity would cool the area around north-east America and Western Europe. Luckily, that will slow some of the other effects of global warming in that area! Third, temperature rises and changing landscapes in the artic circle will endanger several species of animals. Only the most adaptable will survive. Fourth, global warming could snowball with the ice caps gone. Ice caps are white, and reflect sunlight, much of which is relected back into space, further cooling Earth. If the ice caps melt, the only reflector is the ocean. Darker colors absorb sunlight, further warming the Earth. 2. Economic consequences Most of the effects of anthropogenic global warming won’t be good. And these effects spell one thing for the countries of the world: economic consequences. Hurricanes cause do billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these. 3. Increased probability and intensity of droughts and heat waves Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves. Africa will receive the worst of it, with more severe droughts also expected in Europe. Water is already a dangerously rare commodity in Africa, and according to the Intergovernmental Panel on Climate Change, global warming will exacerbate the conditions and could lead to conflicts and war. 4. Warmer waters and more hurricanes As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes. We saw in this in 2004 and 2005. 5. Spread of disease As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them. Indeed some scientists believe that in some countries thanks to global warming, malaria has not been fully eradicated.

David Takayoshi Suzuki was on born March 24, 1936, is a Japanese Canadian academic, science broadcaster and environmental activist. Suzuki earned a Ph.D in zoology from the University of Chicago in 1961, and was a professor in the genetics department of the University of British Columbia from 1963 until his retirement in 2001. Suzuki has been known for his TV and radio series and books about nature and the environment. We expect to acknowledge more from him in the near future.

The Greenhouse effect

Hurricanes to Global Warming? Hurricanes have grown significantly more powerful and destructive over the past three decades, according to atmospheric scientist Kerry Emanuel of the Massachusetts Institute of Technology. In his new analysis of tropical hurricane records, which he reports online today in the journal Nature, Emanuel finds that both the duration of the storms and their maximum wind speeds have increased by about 50 per cent since the mid-1970s. Moreover, this marked increase in the energy release has occurred in both the north Atlantic and the north Pacific Oceans. Unlike previous studies, which have focused on whether hurricanes are becoming more frequent, Emanuel's study is one of the first to ask whether they are becoming more fierce. "It's an innovative application of a theoretical concept, and has produced a new analysis of hurricanes' strength and destructive potential," says Jay Fein, director of the National Science Foundation (NSF)'s climate dynamics program, which funded the research. And that analysis, in turn, "has resulted in an important measure of the potential impact of hurricanes on social, economic and ecological systems," Indeed, as Emanuel himself says, "the near doubling of hurricane's power over the period of record should be a matter of some concern, as it's a measure of the [future] destructive potential of these storms." Also of concern, he says, is that the increases in storm intensity are mirrored by increases in the average temperatures at the surface of the tropical oceans, suggesting that this warming is responsible for the hurricanes' greater power. Since hurricanes depend on warm water to form and build, Emanuel warns that global climate change might increase the effect of hurricanes still further in coming years.

Burning Fossil Fuels ? Coal, oil and natural gas are the three different forms of fossil fuels that are widely used. They are formed by the process of anaerobic decomposition of organic matter under the surface of the earth for millions of years. Large scale use of fossil fuels started since industrial revolution. Today, they are the most cheap sources of energy available for the use of both personal as well as commercial purposes. Petroleum is used to fuel our vehicles while coal and natural gas are used to produce electricity for our homes and offices.
