The researcher states that the current climate change is as a result of huge amounts of greenhouse gas in the atmosphere. The greenhouse gases include Carbon IV oxide, methane (CH4), Ozone (O3) and water vapor (H2O). Scientific research has proven that the huge amount of greenhouse gas in the atmosphere results from burning fossil fuel. The rapid increase in greenhouse gases began in the industrial age. Mathez states that the first recordings of climate began in 1958.According to the records, the CO2 content in the atmosphere was 315 parts per (ppm) in volume.

In 2008, the record indicated 385ppm by volume. The records also showed a rising rate of 2ppm in greenhouse gases by volume. This rate of greenhouse gases is significantly high compared to the amount of CO2 800,000 years ago. The disruption of weather patterns as a result of climate change has negatively affected the agricultural sector. Farmers now face an uncertain climate that previous generations did not face. Changes in precipitation, summer heat stress and intense weed and pest pressures are some of the problems modern experience.

How the modern society chooses to solve these problems may also positively or negatively impact the future generations. Climate change also contributes to the occurrence of extreme weather patterns. One particular example is the heat wave that occurred in Europe in 2003.The rainfall recorded during this heat wave was 50% below normal. Currently, agriculture and grazing occupy 40% of the earth’ s land surface. Agriculture is also responsible for 6% of the world’ s GDP. In developing countries, agriculture is the primary source of livelihood for 70% of the rural The major global concern is that the prevalent issue of climate change may result in a widespread reduction in food supply.

This massive reduction will, in turn, lead to hunger and starvation. Temperature and precipitation changes are the outcome of the prevalent climate change. The rising temperatures and adverse precipitation changes affected the production of horticultural crops. Issues such springtime flooding delays planting, contributes to root damage and soil loss. The U. S supplies approximately 30% of wheat, corn, and rice on the global market. According to researchers, there may an initial expansion of grain and oilseed production owing to the rising temperatures.

However, this initial expansion may be short-lived, particularly owing to the varying precipitation patterns.
