Global warming has given rise to the climate changes which is one of the most addressed global problems. Millions of people are getting influenced with the variations in the climate conditions which have affected the lifestyle of many individuals all over the world. Thanks to the introduction of the new technologies and the greater energy efficiency methods which have given birth to problems such as green houses gases affects, one of the many reasons behind the climate changes. “Over the last hundred years, the earth’s average temperature has increased by three quarters of a degree centigrade (1.3 F) this seemingly minor change may strike some people as inconsequential. However if global warming adjusts just another 4 C (7F) or so to the atmospheric temperature, both Greenland and Antarctica can be on their way to meltdown” (Jerry 2008.) The extreme changes in the climate conditions couple with the green house gases emission will cause the glaciers to melt, which will as a result cause the sea water to heat and will expand thermally. One of the biggest threat imposed by global warming to the world is that of the rising sea levels, for which the consequences are going to be catastrophic. As discussed above, the expansion of the sea water causes the sea level to increase, because the water warms up due to the constantly changing climatic conditions. Rate of change in the sea level from the year 1870-2000 was 1.70 mm whereas in comparison to this figure the rate of change in the sea level from 1993 to 2012 is 3.12 mm. (NASA 2012) As per the recent reports, one of the massive ice shelves of Antarctica are also decreasing because of the warm water that resides below the ice shelves. Due to the shrinkage of the ice levels, the sea water level will start rising at a much faster rate than what the scientists have been predicting so far. The western chunk of Antarctica is losing 23 feet of its floating ice sheet each year. (Mail Online 2012) However after intense research, the scientists have been able to conclude that the rise in the sea level is directly associated with the thermal expansion, which is the water of the ocean getting warm causes it to expand. Secondly, the change in the sea level can also be associated with the land based ice which is melting at a rapid speed due to global warming and the emission of the green house gases. Since most of the stored water on land is found in the form of glaciers and ice sheets, this means that melt down of these forms will directly result in the sea level increment. Rising sea level is a justification or rather a proof that the world today faces a threat from the anthropogenic (human based) warming contributions, which in the late 20th century has caused the sea level to rise to new levels. The contribution to the rising levels is associated with Greenland, Antarctica, and the melt down of other important ice sheets and glaciers. The effects of the constant changes in the climate conditions and then the rising sea levels can have devastating effects on the human kind. As per the increases which have been mentioned above, it is also been shared that with respect to these changes, there will be a vast number of influences on the coastal systems. Coast erosion, changes in the quality of the water, high storm flooding are few of the many effects that this rise will bring along with itself. There will also be changes in the surface water quality which will result in the monetary losses as well as non monetary

The threat to world agriculture is the most important of all the damages caused by the “unarrested” global warming. According to few studies, a small amount of warming in the next few decades might prove to have certain global benefits on the agriculture.
Global warming has been defined by various scholars as the rise in heat of the earth’s ambiance and its expected continuation resulting to the earth’s surface temperatures increasing (Maslin 2). The issue of global warming has aroused a variety of problems in reference to the nature, how it occurs, and its cost because of the consequences.
Food supplies, perhaps most importantly to human beings, depend in large part on the ability of the oceans to produce fish and other edible animal/plant life. In addition, ocean water produces a number of valuable minerals like salt, magnesium, and bromine, which all serve useful functions in society.
What are the problem with the Aral sea?
Aral Sea, once grouped among the top largest inland water bodies is situated in the plains of Turan. This sea stretches to cover parts of the republics of Uzbekistan and kazakstan. For many years this sea was considered a central hub were hunters, traders, merchants and fisher met and engaged in diverse economic activities.
The author of the study will highlight the features and benefits of the SAS programs. The study will also highlight its effectiveness especially to the students studying Humanities, Social science and Environment. Finally, the study will also give an insight as to how the Semester At Sea program will help in imparting theoretical and practical knowledge to the students.

Many scientists have been interested in discovering how climate change relates to sea level. It has been established that climate change is responsible for the increase in sea volume. Basically, there are two ways in which climate change triggers an increase in sea volume.
