Between 1979 and 2010, there has been a notable increase in temperature trends throughout the African continent. These temperature trends are measured with Microwave Sounding Units (MSU), Remote Sensing Systems (RSS) and the University of Alabama in Huntsville’s datasets. Africa is quite a unique continent as it straddles the equator, so the upper half of Africa is in the northern hemisphere, whilst the lower part of Africa is in the Southern Hemisphere. This has a direct effect on temperature and rainfall trends in Africa, this is apparent as the northern half of Africa is primarily arid, desert regions, whilst the southern part of Africa is made up of savannahs and rainforests. It is because of the vast differences in climate between the northern and southern parts of Africa, that I will be looking at climate and temperature variations in the northern, southern, eastern and western parts of Africa separately, to try and gain an understanding of the variations over the whole of Africa.
Firstly, I will look at the temperature trends within the southern hemisphere of Africa. The southern hemisphere of Africa receives more rainfall and, therefore, has far more vegetation and natural greenery.
Southern Africa’s normal temperatures show summer maximums and winter minimums, however, the rainfall here is unpredictable and erratic. Twenty-three climate stations were used to help make predictions about the variability of South African climate. At the end of the experiment, the mean seasonal temperatures were compared and it was recorded that temperature trends are not consistent throughout the year, with autumn displaying a maximum trend and spring displaying a minimum trend. It was also discovered that temperature trends, in general, se...

Essay The Effects Of Climate Change On Climate Variability

- “In nature there are neither rewards nor punishments – there are consequences.” this quote argues that identifiable consequences of climate change are substantial to understand climatic events (Ingersol, 1899 p.270 cited in Burroughs, 2007). The term ‘climate change’ indicates the statistically long – term period environmental deviation of the global atmosphere including the averages state of the climate or natural climate variability (the Intergovernmental Panel of Climate Chang (IPCC), 2007). During the past historical and recent decades, climate change and the Earth’s responses illustrate that most regions have been changed rapidly in the variability of climate including increasing the av...   [tags: Greenhouse gas, Carbon dioxide, Climate change]

Climate Variability And Climate Change Essay

- Climate change is a change in global or regional climate patterns. Most of the cold extremes of the world is experiencing warming at a more rapid pace than its warming extremes. In fact, the true cold season now exists in only the polar extremes of the African continent. Western Africa and Guinea are found to also face a reduction of precipitation while its neighboring regions, although also affected with reduced rainfall, are more prone to extreme rainfall, indicating the effect of the change global warming has brought (Aguilar, Aziz Barry, Brunet, Ekang, Fernandes, Massoukina, & Zhang, 2009)....   [tags: Climate, Climate change, Africa, Global warming]

Climate Changes And Climate Change Essay

- Climate refers to the weather conditions that occur and prevail in particular regions over an extended period of time. Climate change is the change in the properties of the climate system, referring to significant changes in its mean state, and in its variability and extremes (VijayaVenkataRaman S, Iniyan S, Goic R, 2012). Changes in climate can occur naturally due to internal and external processes, or can occur due to anthropogenic changes in the composition of the atmosphere and anthropogenic changes associated with land-use (VijayaVenkataRaman S, Iniyan S, Goic R, 2012)....   [tags: Global warming, Climate change, Weather, Climate]

Climate Change : Climate And Biological Factors Essay

- 3.2 Modelling Aapproaches Climate change impact would depend upon complex interactions of climatic and biological factors with technological and socio-economical changes that are difficult to predict. Quantitative (modelling) approaches, which allows investigation of multiple scenarios and interactions simultaneously, will thus become more important for impact assessment (Coakley and Scherm, 1996). Sutherst et al. (1996) have given a framework for such model-based assessment of climate change impacts....   [tags: Climate change, Global warming, Weather, Climate]

Human Activity Causes Climate Change Essay

- The general populous in the developed world and 97% of scientists can agree that our global climate has undergone such irregular phenomena and increased climate variability that climate change can no longer be claimed as unimportant. There are those who still refuse to acknowledge the existence of such change or that the shifts in climate are caused by humans. The major question needs to be posed yet again: Is there actual statistical evidence to verify that climate change is not a short term observed trend in global climate and an imminent danger....   [tags: Climate change, Greenhouse gas, Climate]

The Climate Change Of Coral Reefs Essay

- Many terrestrial and marine species have shifted their geographic ranges to avoid their potential extinction posed by ongoing climate change (IPCC, 2014). Geological records show evidence of range shifts in coral reefs during the last interglacial period when sea-surface temperatures were 0.78 °C warmer than today (Kiessling et al, 2012). Coral bleaching and mortality is often associated with ocean warming as well as ocean acidification. High sea-surface temperatures have been increasingly documented along the coast of Belize, Honduras, and Guatemala (Eakin et al, 2010) and have resulted in frequent bleaching events of the Mesoamerican coral reef....   [tags: Global warming, Climate change, Mangrove]

Essay about The Climate Change And Its Effect On The Environment

- There are so many factors in today’s growing population and its action that contributes to the environment. With the rise in population there is also increase in the needs and demands resulting in more production of food and assets. Most of the actions of human lead to increased environment risks which in return will only effect the livings of this planet. Currently mostly all individuals have at least one form of vehicle for transportation. There is increased industrialization and requires a lot of energy which comes from fossil fuels as the need for oil increases to fuel large amounts of humans daily work and chores....   [tags: Global warming, Climate change, Climate, Weather]

Accelerated emissions of green house gases (GHGs) globally, from combustion of fossil fuels and unsustainable land use practices is the key driver of anthropogenic climate change. Climate change is manifested in; variations in minimum and maximum temperature, frequent and extensive droughts, high intensity rainfalls and floods, seasonal and regional pest and disease prevalence leading to conflicts for pasture and wate...   [tags: Climate change, Greenhouse gas, Global warming]

Agriculture Is Directly Dependent On Climatic Variability Essay

- Schule, (2007) allege that agriculture is directly dependent on climatic variation such as temperature and rainfall, which dictate crop and livestock selection for a specific location as well as cultivar choices and cropping calendars. He indicates that with a 2°C increase in temperature and a 10% reduction in rainfall, the maize yield for South Africa, for example, is expected to experience a reduction of 0,5t/ha. Taylor, (2003) argues that with proper research sorghum and millets could play a more important role and can offer better long term food security than maize....   [tags: Cereal, Agriculture, Food security, Poaceae]

Essay about Climate Change Is The Global Warming

- Parties who feel that the Earth is not warming claim that the global average temperatures have not gone up since 1998. The argument follows the idea that the greenhouse effect would not make each year hotter than the previous one since there are numerous processes that impact the global average temperatures and climate, for instance, the internal variability in the climate system, changes in solar forcing, and anthropogenic increase in atmospheric greenhouse gases. There thus follow periods of relatively stable, or even cooler, temperatures....   [tags: Climate change, Global warming, Carbon dioxide]
