Man flew into space, tamed atomic energy, found a way to cure many diseases that were considered incurable, and almost every day is marked by a new breakthrough. However, there is a downside. For a long period of time, people did not think about the consequences of their exponential development. Climate change is a significant and lasting change and the largest problem facing our planet.
Climate change is usually defined as the rise of earth's temperature, precipitation, humidity, and sea level. It is a serious phenomenon on environment and living organism on the earth's surface. It also plays a significant role o. This essay will first suggest that the biggest problem caused by this phenomenon is the flooding of homes and then submit building flood protection as the most viable solution. The foremost problem caused by sea levels creeping up is the flooding of peoples' residences.
The degree of sensitivity will, however, vary from one species to the other. Changes in temperature and perceptive patterns will affect several weather sensitive sectors like agriculture, forestry, water resources and coasts. The impact of these changes will also be felt on human systems affecting human heal. Is the threat of global warming real?
Is it man-made or is this just a natural cycle of earth? Land masses have drifted slowly slowly across the globe. The continents are part of the plates and drift with them over the globe. These land masses drifted slowly apart, eventually reaching their present locations. This event was called as continental drift However, the shape of earth before Pangaea is a matter of speculation. Reconstructions based on deep sea sediment cores indicate that during the Ice Age, the climate shifted numerous times between conditions favourable to the expansion of glaciers and was known as glacial climate.
When the conditions were conducive to the decay of glaciers, it was called as interglacial climate. Greater changes in temperature were observed in some latitude belts and less in others.
The postglacial warming trend culminated in the so called climatic optimum, about 5,to 7, years ago, a time when global temperatures were somewhat warmer than at present. However, since the industrial revolution, human activity has had a large impact on the global climate system, increasing the amount of greenhouse gases in the atmosphere, trapping heat and contributing to global warming. While this may seem like a small change, global temperatures are generally quite stable.
The difference between today global temperature and the average global temperature of the last ice age is only about 5t. However, over the last century we have witnessed a decrease of nearly 10 percentage snow cover and a percentage decrease in spring and summer sea-ice in the northern hemisphere] Other observed changes that have been linked to climate include longer growing seasons, increases in rainfall and rainfall intensity in the northern hemisphere, and shifts in when ice freezes and breaks up on rivers and lakes.
The IPCC has projected that global average surface temperatures could increase 1. Daily maximum and minimum temperatures will increase as well as the number of hot days-, with less cold and frosty days. The global average precipitation and evaporation is also expected to increase by about one to nine percent. The precipitation changes are expected to vary from region to region, with increases over the northern mid to high latitudes and in Antarctica during the winter.
The intensity of extreme weather events is also likely to increase, with greater extremes of both flooding and drought. Despite all of the information and evidence that scientists have uncovered related to changes in climate, there continues to be uncertainty around the causes of climate change and its potential impacts. These uncertainties stem primarily from the science itself as well as from the future of human behaviour, especially as it relates to the amount of natural climatic variability and future greenhouse gas emissions.
Many of these factors will depend on human behaviour, which may be influenced by effects on health and the quality of life, technological advances, and policy changes. Therefore, when dealing with climate change, scientists need to make a number of assumptions with an ever increasing number of models that focus on different parts of the climate system; all of which makes pinpointing exactly what to expect in terms of future climate change that much more difficult.
However, climate involves the entire climatic systems including hydrosphere, lithosphere, [biosphere, and atmosphere and cry sphere. It affects geomorphologic process, soil formation process, plant growth and development. In exchange, man also exerts influence on climate through various activities and is consistently changing the atmospheric conditions.
Global Climate Change: Essay on Global Climate Changes! Since the beginning of human civilization, mankind has lived in a competitive relationship with nature. His relentless pursuit of progress, comfort and security has resulted in increased stress on environment, particularly since the industrial.
Global climate has been changing and still continue to change. Over a long period of time, climatic fluctuations may be such that, a shift in type of climate prevailing over a given area, takes place.
Global Warming and Climate Change Essay 1 ( words) The whole climate of the world is changing regularly because of the increasing global warming by the natural means and human activities. This undergraduate essay on climate change describes the causes and effects of climate change and their effects on the environment. climate change, global warming, greenhouse gases. like volcanic eruptions and changes in the amount of solar energy, are natural. Climate can change if there is a change in the amount of solar energy that.
The above short essay topics on global warming covers the various far reaching effects of climate change on the earth’s ecosystem.
