Climatic changes have been experienced for a while, and people tend to ignore the effect. The article reviews these observable features of greenhouse effect between 1900 and 2000. In the span of the century, a lot has happened particularly based on the industrialization which has increased carbon emission to the environment thereby contributing to an imbalance in the ozone layer. Through observing the historical changes, the authors change the perception of the reader implying that there is need to change in the way people treat the environment. The investigations regarding some the unusual climatic conditions like the El Nino and changes of the seasonal rainfalls shows some of the negative impacts of the climatic changes.
The article is relevant to the study in that it explains the observable climate variability and creates an impression of something that people have observed but ignored to respond. Furthermore, the work is based on African climate context, rainfall variability, climate scenarios, and seasonal forecasting. Through these elements, the article proves the impact of climatic changes in Africa thereby making it an important part of the study.
The authors of the article are reputable scholars whose work is submitted to institutions of higher learning and different environmental bodies including the government agencies and international non-governmental organizations. Moreover, Mike Hulme is a leading professor of Human geography at the University of Cambridge. While Ruth Doherty is a professor of Atmospheric Science in the School of Geoscience. Todd Ngara, on the other hand, is a senior researcher at the Technical University of Denmark. Professor Mark New was elected as Pro-VC for the climatic change at the University of East Anglia. All these authors are professors or renowned institutions of higher learning which makes them credible writers of the piece.

The article examines the effects of climatic change on the health of the people in future decades. Given that the temperatures are increasingly rising surpassing the safe threshold of 20C above pre-industrial average, there is the likelihood that people will experience extreme weather conditions. The changes will be high in regions with higher latitudes and other regions with a different rate. The report outlines the anticipated threats as a result of these changes in weather patterns. Food security, diseases, water challenges, and vulnerable human settlement among other factors will be influenced by the extreme climatic changes thereby influencing the normal human life.
The article is essential to the study because it brings a new perspective to the way people perceive the issue of climatic changes. From a broad perspective of seeing the issue as a global issue that does not affect people individually, the literature makes the issue a personal one. It creates the feeling that everyone has a personal role to play in establishing a safe environment because it influences their lives. Moreover, as the article shows that the climatic changes affect Africa as part of the globe but most importantly shows the influence on the latitudes where extreme changes are expected to be felt.
Additionally, the authors are accredited professors with a vast experience on the topic making them suitable to provide the overview of the influence of climatic change on a personal level. They develop an intimate feeling of people being part of the globe that is experiencing the changes and that the changes influence their lives.

The article critically examines the impact of the change of weather patterns and its influence on the food production process. In the past, Africa had enjoyed a stable weather pattern that supported food production to a large extent. However, with global industrial growth, there has been excessive carbon IV oxide omission that has influenced the ozone layer. The once stable climate is now unable to provide sufficient food as unpredictable weather pattern influence the food production process. As a result, the article takes a keen interest in examining how the changes are influencing the overall food production in Africa and other parts of the world. Such information will provide critical guidelines on food security not just in Africa but also in other parts of the world. Additionally, the literature offers insight into other elements of productions such as soil ph. that are influenced by acidic rainfall and how they influence food production.
When examining the credibility of the authors, it is evident that they are all well versed in the subject. They are researchers from different institutions with the world-class educational background. As a result, they offer thoroughly researched worked putting into perspective the issue of food insecurity as a direct consequence of climatic changes.
The article is relevant to the topic in that it examines some of the impacts of the negative climate change and the potential direct influence on the lives of the people. The speech by Al Gore shows that it is time people take action against the negative climatic changes. The article supports that opinion through showing people that their food supply is at risk. Thus, the literature is critical in the subject through proving the need of change.
