Air temperature trends over the African Continent.
Air temperature (i.e. climate change) is one of the controversial topics to a lot of researchers. Mainly around problems related to where it is exposed and what gives rise to it (King’uyu et al., 2000). A lot of information is shown by different researchers and findings, as New et al. (2006) states that there has been less information on daily air temperature patterns. According to King’uyu et al. (2000) ,the research on air temperature reports have indicated that the global mean air and surface temperature has been rising over the last 100 years which shows that the has been a remarkable increase in air temperature patterns. The following discussion highlights some of the important points that were raised by different researchers on varying air temperature patterns in the African continent, the causes and the consequences of the occurring changes. The discussion is structured in the following way: The first paragraph gives a definition of air temperature, the second paragraph gives a clear outline of the varying air temperature patterns, the third paragraph gives the causes of the extreme and unexpected air temperature trends, the fourth paragraph raises the observed consequences, while the last paragraph sums up the conclusion of all the researchers came to.
Burroughs (2003) defines air temperature as the “the temperature indicated by a thermometer exposed to the air in place sheltered from direct solar radiation”.
Collins (2011) stated that there was a remarkable increase in air temperature patterns all over Africa .A rise in a row of dry days were found over Southern Africa in the last decades of the twentieth century (New et al. 2006), where temperatures were not reliab...

...ce tops on the peak of Mount Kilimanjaro will disappear due to the rapid heating and warming up of the air. Lastly, these high air temperature patterns would lead to a loss of habitat to many of the animal species and also a lot of rainfall on the African continent which might not favour some countries as there can be floods.
In conclusion, having looked at all these researches, the findings indicate that there has been an increasing pattern in air temperatures since the beginning of the twentieth century, however, some areas experienced hotter than normal temperatures, which was noticed by the Remote Sensing System and the University of Alabama in Huntsville (Collins, 2011). This increase in air temperature is mainly due to human impacts on climate. These rising air temperature patterns will end up leading to unbearable consequences in the future.

For a significant number of years it has been evident that global temperatures were rising and that human activity is a major contributing factor to this rise. The rise in temperature is not only heating the planet but having an adverse effect on the global climate.
Climate, weather, and meteorology are 3 words that seem to be the same but in reality differ significantly. Two of these concepts pertain to the atmosphere but differ in what time and place they are studied in, and the last one is studying these concepts.
Climate change refers to shifts in the mean state of the climate or in its variability, persisting for an extended period of decades or longer (Ziervogel and Zermoglio, 2009). It is the change in average atmospheric behavior, and change in the patterns of variation around this behavior (Rumbach and Kudva, 2011). The Intergovernmental Panel on Climate Change (IPCC) declared that climate change is unequivocal as evidenced by observed changes in several global and regional climatic indicators (IPCC, 2007). At the country level, climate change refers to observable changes and permutations (undefined geographic variations) of temperature, rainfall and extreme climate events and their single or collective impacts on various agricultural production (Lasco, et al., 2009).
...ld. Globally, more intense hurricanes and downpours could cause billions of dollars in damage to property and infrastructure. Declining crop yields due to prolonged drought and high temperatures, especially in Africa, could put hundreds of thousands of people at risk for starvation. The Ski resorts located in the lower altitudes of the Swiss Alps have difficulty obtaining bank loans because of declining snow.
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
Furthermore, this analysis must take place amidst serious gaps in the existing research and technology concerning the developing climatic conditions. For these reasons, global warming stands as one of the most daunting policy issues facing our world today. This is compounded by the debate over the very existence of climate change. While countless sources of empirical evidence testify to the very real presence of climate change the world over, considerable denial of the phenomenon still exists. The argument has been made that evidence of climate change is a gross overstatement, or in some cases, a complete fabrication.
There are many causes and consequences of climate change discussed throughout this Encyclical. One of the most important would be the extreme weather. “In recent decades this warming has been accompanied by a constant rise in the sea level and, it would appear, by an increase of extreme weather events, even if a scientifically determined cause
There is no longer any question that our world climate has changed (King, 2004). Over the last 100 years, "temperatures have risen by about 0.6 degrees Celsius and global sea level has risen by about 20cm" (K...
Climate change has become of the world’s major issue today. The earth’s climate is always changing in a very fast and also in different ways. Climate changes affect our lives psychologically, emotional and also physically. Climate change is defined as a long term change in the earth’s climate, especially a change due to the increase in the average atmospheric temperatures. Due to this change in temperature, a lot of changes has occurred in our environment, these changes include rising sea levels, flooding, melting of polar ice caps, hotter days, colder nights and heat waves. These climate changes plays an important role in shaping our natural ecosystem, our human economics and also the most important, it affects the human race. For
Climate change is likely to increase disease risk and mortality and increase communicable diseases. In order to stop the climate change, we can limit the amount of deforestation and more trees can have more green plants. small trees can improve the environment climate, keep the air humidity and its photosynthesis can effectively absorb carbon dioxide, then the air is more fresh and clean. Because of the climate change, there will be droughts in some dry areas, such as Southern Africa, Southern Asia, Mediterranean, Sahel region of Africa and United States Southwest. The resources of water in these dry areas will decrease. In these areas, the climate change has a huge impact on people's lives, and it can cause them to die. If we do not take climate change seriously, then the world will become more and more hot, and we will lack of water. It is impossible for people to change the climate right away, it takes
Climate change is an inevitable phenomenon that is being experienced globally in various forms such as temperature rise. Sea level rise, droughts, floods, hurricanes, landslides, etc. According to the forth assessment report of the IPCC project even with immediate implementation of mitigation strategies global climate change will continue for decades. Climate change is inflicting serious consequences on human wellbeing and will continue to inflict damages in the future. It is estimated that mean global temperature will rise by 1.8 ºC - 4.0 ºC by end of the 21st century (Izaurraade, 2009). A new global climate model predicts that in the coming decade the surface air temperature is likely to exceed existing records (Smith et al., 2007). Growing season temperatures in the tropics and subtropics by end of the 21st century will exceed the most extreme temperature recorded in the history (Battistic and Rosamond, 2009).
