Ice Age Extinctions Of The Megafauna

Many of the larger animals such as mammoths and bison travel in herds, and that, along with their large size, protects them from predators. However, when the predator is Mother Nature, there is virtually no defense. For modern day elephants, drought is the biggest concern. It can take twenty percent of a herd every year, but the e...

Effects Of Global Warming Animals And Plants
1,848 wordsGlobal Warming Is A Serious Issue That Should Have Immediate Attention As Vice President Al Gore has said about the threat of global warming, it is "the most serious problem our civilization faces" (2). It has become quite an issue internationally because of the threat of increasing greenhouse gasses. It is these gasses, when released into the air, accumulate and then trap the heat inside our atmosphere. Our climate is greatly affected by this. Therefore, affecting all of the organisms on earth,...

Fossil Fuels Greenhouse Gases
1,295 wordsThe importance of the greenhouse effect was just conceived in the mid-twentieth century. "For billions of years, cosmic forces shaped Earth, and land and air coevolve at an almost inconceivably slow pace to create a climate in which human beings and other creatures could flourish. " (Francesca Lyman). Now, for the first time, humanity has the power to change the global climate. By releasing the huge amounts of carbon stored in fossil fuels over millions of years, we are distorting the natural ca...

Taking Into Account Lava Flows
1,159 wordsWhat event occurred at the division between the Triassic and Jurassic periods, and why was this important to the dinosaurs? The extinction is a topic that now requires rather more digging than talking. The Triassic and Jurassic periods were remarked by changes that influenced both: relief and biologic forms of life. The dinosaurs were the most typical representatives of fauna for the Triassic and Jurassic periods. These periods are characterized by tectonic activity, worsening of climate conditi...

Carbon Dioxide Methane Nitrous Oxide
705 wordsThe earth s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth s climate responds to these gases, global temperatures are rising. Energy from the sun drives the earth s weather and climate, and heats the earth s surface; in turn, the ea...

These changes have effected society in more than one way. However, there is nothing society can do about the long term influences of climatic changes. Society has tended to address the short term effects of climatic changes that influence the global temperatures within the life span of present generations. The following will show how climatic changes does eff...

Fossil Fuels Greenhouse Gases
405 wordsGlobal Warming We have an obligation to weigh the risks of inaction against the cost of action. In that regard, global warming is no different than any other problem. But global warming is novel in one respect. It brings with it the possibility of global disaster, and we have only one Earth to experiment on.

995 wordsAccording to available estimates, forests cover more than one quarter of the worlds total area. About sixty percent of these forests are situated in tropical countries. However, these forests are disappearing at a very fast pace. Between 1980 and 1995, an area larger than Mexico had been deforested. This accelerated destruction of forests poses a serious threat to the environmental and economic well-being of the earth. Several studies have demonstrated that natural forests are the single most im...

Effects Of Global Warming Carbon Dioxide
1,403 wordsThe Problem of Global Warming First discovered at the turn of the century by the Swedish scientist Arrhenius, global warming was initially thought to only cause increased greenhouse gases from coal combustion emissions. It wasn? t until fifty years later that the real causes and effects of global warming would be discovered. A British scientist by the name of Calendar correlated the 10 % increase of atmospheric Carbon Dioxide between 1850 and 1940 with the observed warming of northern Europe and...
