"Is Global Warming End of The World ?"

Our world is five billion years old and it put up with a lot of trouble of people nearly five million years. While people become more intelligent, technology improves, life bocomes easier, but problems of earth increase. The hole in the ozone layer becomes bigger, world warms up and global warming become bigger problem for people. Unless we act now, our children will inherit a hotter world, dirtier air and water, more severe floods and droughts, and more wildfires.

What do we know about global warming? Increasing heat on the earth surface because of the gases given to the atmoshere by the people which creates the greenhouse effects is called Global Warming. According to their studies on global warming, three scientists agreed, "...what matters is how the earth is warming, not just that it is"(1) (Michaels, Knappenberger and Davies, 2000). And they state that no known mechanism can stop or even significantly reduce global warming in the foreseeable future. Scientists have either certain knowledge or big unknowns about global warming. It is known for certain that human activities are changing the composition of Earth's atmosphere. There is no doubt that atmospheric buildup of carbon dioxide and other greenhouse gases is largely the result of human activities. Some of the largest uncertainties are associated with events that pose the greatest risk to human societies. There is the possibility that a warmer world could lead to more frequent and intense storms, including hurricanes. However , the jury is still out whether or not hurricanes and other storms will become more frequent.

Effects of global warming can be classified in two main topics: Effects to the earth and Health effects. Warmer temperatures increase melting of mountain glaciers, increase ocean heat content, and cause ocean water to expand. Largely as a result of these effects, “global sea level has risen 10 to 25 cm over the past 100 years. On average, 15 to 30 meters of beach are lost for every 30 cm of sea-level rise” (2). “Over the past 150 years, the majority of mountain glaciers monitored have been shrinking, and scientists predict that, under some plausible warming scenarios, the majority of glaciers will be gone by the year 2100” (3). Furthermore global warming can cause some health problem. More frequent and more intensive heat waves could result in more heat-related deaths. Global warming is expected to increase the potential geographic range and virulence of tropical diseases as well.

We can say that most important consequences of global warming are climate pattern change and ecosystem disruption. Average temperatures will rise, as will the frequency of heat waves. “Since 1980, the earth has experienced 19 of its 20 hottest years on record, with 1998 the hottest and 2002 and 2003 coming in second and third” (4). Warmer temperatures could also increase the probability of drought. Greater evaporation, particularly during summer and fall, could exacerbate drought conditions and increase the risk of wildfires. “The 1999-2002 national drought was one of the three most extensive droughts in the last 40 years” (5). The increase in global temperatures is expected to disrupt ecosystems and results in loss of species diversity, as species that cannot adapt die off. The first comprehensive assessment of the extinction risk from global warming found that more than one million species could be committed to extinction by 2050 if global warming pollution is not curtailed. A recent study published in the prestigious journal Nature found that “at least 279 species of plants and animals are already responding to global warming” (6).

In conclusion, effects of global warming on earth and people increase day by day. Some organizations including Pentagon begin to make public their bad scenarios for the near future. If we don’t want to come true this scenarios we must do something. But before we begin spending money on "mitigation science", we should learn more about the fundamentals of global warming science.

Dünya "Küresel Isınma" laflarıyla çalkalanmadan önce, 2004 yılında, üniversite birinci sınıfta, İngilizce dersinde sunum konum "Küresel Isınma" idi :)

İnternette bu kadar çok kaynak yokken, nette biraz araştırma yapıp bu komposizyonu yazmıştım ve sunum yapmıştım.

Sınıfta tek 100 alan bendim :)

O yüzden Küresel Isınmanın ben de hep özel bi yeri vardır :çılgın:

Harika bir araştırma ve sunum yapmışsın Erkan'cığım ellerine sağlık. :erkan:

Bu değerli sunumu bizlerle paylaştığın için teşekkür ederim canım benim. :hale:
