Human health, agriculture, and infrastructure are some of the aspects which have been affected by the changes in climatic patterns as a result of global warming. Global warming has increased the rate of melting of the ice caps at the earth's poles as well as glaciers and ice sheets in Antarctica, Greenland, and the sea ice on the Arctic sea (Hanjra & Qureshi, 2010). The events have impacted human health by increasing and spreading diseases. It has affected the production of food and caused damage to infrastructures such as roads, water supply mechanisms, bridges, buildings, airports, railways, and electrical connections throughout the world. Moreover, global warming has increased the rate of pollution which is harmful to the environment, animals, and plants, and with adverse effects on humans. Changing weather patterns have affected changes in food production by increasing precipitation such as snow and rainfall and rise in sea levels as witnessed in the last century. An increase in precipitation has reduced food production as it presents harm to food crops by exposing them to extreme climatic conditions. Increased moisture and reduced sunlight lead to the destruction of plants before they produce harvest leading to inadequate food production and limited stock for consumption. On the other hand, global warming has also increased drought in countries that are already prone to drought leading to minimal or zero production of food for consumption (Trenberth et al., 2014). Changes in climatic conditions have increased the spread of diseases. An increase in heat provides favorable conditions for the growth of bacteria and parasites which cause diseases. Diseases such as malaria have spread to all parts of the planet due to conducive climatic conditions for the breeding of malaria-borne diseases. Other diseases arising from pollution such as cancer and other cardiovascular diseases (Parry et al., 2004) have also spread across the world and can be traced back to global warming. Pollution caused by global warming leads to the deterioration of human health by continually introducing harmful gases and bacteria which harm different body systems such as the digestive, respiratory, and immune systems. A shift in the climatic conditions has resulted in damage to homes, transportation the electric grid. Destructions are increased by hurricanes and storms which have become stronger due to the increase in global warming. The melting ice caps increase sea levels which affects when storms and hurricanes in strength and duration. When they occur, the winds have adverse effects on buildings, and infrastructures such as roads and lead to the destruction of electrical lines and poles. Global warming also increases air pollution due to increased emission of carbon and nitrogen and other harmful pollutants which lead to smog and bad ozone which is destructive to buildings and infrastructure (Wheeler & Von Braun, 2013). An increase in pollution has been witnessed as a result of global warming. Water, air, and environmental pollution is evident and continues to increase and affect various regions caused by the changes in climatic conditions. Global warming has led to the contamination of freshwater as the ice caps melt. The melting ice caps drain into the water sources contaminating them and leaving populations that were dependent on such water sources with no alternative sources. Pollution arises as due to emissions of pollutants, global warming facilitates the breakdown of chemicals and substances which pollute the environment and the air making it unsuitable for breathing and has cause respiratory diseases and illnesses.
