Climate change is one of the major issues surfacing earth over the past century. The earth’s temperature has increased over the years leading to detrimental effects on the economic and life sources of people, especially that of agricultural production and livestock. The Merriam-Webster online dictionary (2014), defined climate change as a change in global climate patterns apparent from the mid late 20th century. The Intergovernmental Panel on Climate Change, IPCC, (2007) predicts that by 2100 the increase in global average surface temperature may be between 1.8° C and 4.0° C. With increases of 1.5° C to 2.5° C, approximately 20 to 30 percent of plant and animal species are expected to be at risk of extinction. Moreover, the IPCC (2007) purported that climate change has severe consequences for food security in developing countries. There are numerous factors that are solely responsible for this change which are both natural and man-made. Climate change has led to a decrease in quality and quantity of plant produce and livestock because of heat stress, drought and an increase in plant and animal diseases.
According to Health and Safety executive (HSE), (n.d), heat stress is a component of climate change “that causes the body temperature to fail”, and is a global problem which affects agriculture and livestock. The effect of heat stress on Livestock’s has become greater for animals such as dairy cows and beef cattle. When animals are under distress due to temperature rise, they usually cut back on their feeding practices; have a rise in body temperature and faces weight loss. Milk production, milk fat, protein content and the progression of breeding are also affected, especially in dairy cows. When heat stress occurs, dairy cow...

The plants we grow for food needs specific resources to thrive, which includes the night temperature and enough water. A changing climate could create a lot of problems. Climate change could make it too hot and also make it too cold to grow crops in some areas of the world and also climate change can cause drought, which is made by the unavailability of water for irrigation. Climate change is likely to cause stronger storms and more floods, which will damage the crops. . Latin America and Southern Asia is seeing it in lethal storms and floods whereas Europeans are experiencing it in melting glaciers, forest fires and disastrous heat waves (Pearce, 2006). Deforestation is another anthropogenic factor that is causing climate change because of the need for fossil fuel, agricultural lands are being used. Forests are being burnt down by humans on a daily basis. As agricultural lands becomes less in need of growing population, people extend their space by cutting and clearing forest. The land beneath the forest sometimes tends to be unproductive and lacks the natural chemicals for a growing. The plantation will serve as a source of food for a few years after then the land becomes useless because of its infertility, it nutrients get depleted and used up. Deforestation results in numerous problems such as destruction of our natural resources, ecosystem, wildlife,

The effects of climate are felt throughout the world, all living things are affected with it. The effects of climate change are affecting directly the human life. It has been noticed that around the globe, seasons are shifting, temperatures are climbing and sea levels are rising. The world compares to century ago, it has changed drastically and it is becoming worse with climate change. Climate change will rapidly alter the lands and waters which we all depends upon for survival which will leave our children thus the future generation with a different world. In the time to come if not much is done for the case of climate change, There will be shortage of food and drinks, many new illnesses and diseases and some part of the world will become in appropriate for living things to live due to natural disaster. It can be that with the rapid Global warming and climate change, one-fourth of Earth’s species could be headed for extinction by the year 2050.
Earth’s average temperature has increased about 0.8 degrees Celsius since 1880 and another degree could cause even more problems than there already are. Climate change is an important issue to be aware of because it is real and it affects you and the things around you each and every day. Every day animals lose habitats and die because climate change caused there home to burn, or their food sources started to deplete, etc. Along with these, more and more CO2 is being released into the air due to wildfires burning which is causing the atmosphere to heat even more. With the temperature increasing the oceans will become warmer and evaporation and rainfall patterns will change which will affect humans and animals, because we all work together in a system. There are many consequences of climate change like human health issues, and more animals becoming endangered, but the most important consequence is the rising amounts of wildfires.
The causes of climate change are also known to them that though it is not only the human action playing role but it is the main cause of climate change. The effects of climate change does include harm and loss of environment and organisms but it also has impact on the human health. Semenza (2014) displays an assessment report which states that throughout the 21st century, the rapidly occurring climate change will lead to increase in number of humans with ill health in many regions mainly in those of developing countries where citizens face low income. Semenza (2014) also mentions how there are physiological limits to intense heat exposure and the global climate change will turn some parts of the world which are currently highly populated into uninhabitable even if the global temperature rises by 7 degrees Celsius. Johnson (2014) states how El-Niño-related hydroclimate variability will lead to being intensified under global warming mainly in areas as southern Asia which are already stressed by different droughts, floods, and crop yields. Dettinger, Udall, and Georgakakos (2015) mentions how climate change puts risk and threat on water resources in the western United States to an extent that no other part of the country matches it. Dettinger, Udall, and Georgakakos (2015) also states how recent research and studies strictly point a limited number
Species are decreasing and becoming extinct over time due to climate warming. Animals and plants have developed and diversified from earlier forms to become more complex organisms. Not only have living organisms changed, but so has the Earth. Over time, the world itself has changed drastically, not just the climate but the way it looks as well. The ice on the arctic is melting, causing oceans to become more acidic, oceans became deserts and pollution from our everyday lives are affecting the ozone. It all adds up and changes the world negatively. When the world changes, so do the animals within it. Climate warming has been a big part of the change we see in the population of different species. The speed of climate change is excelling, which

Thousands of species have become extinct over the last four decades as a result of changes in land use and as a result of global warming. Whether or not the millions of species can adapt and evolve to climate changes is debatable. As this brief overview will report, the human species is not adapting well to the changes. It must be remembered that increases in the levels of carbon dioxide are certainly responsible for the risk many species face, but so is the way land is used, e.g., rain forest destruction. There is a feedback loop wherein plant life and the climate are interdependent. Each affects the other. When forests are cut down, temperatures in that area will rise. Rising temperatures cause other plant life requiring cooler temperatures To die off.
Forests are ripped up, summers and winters are warmer, ice caps melt making sea levels rise, and many animals have gone further north to live. All of these occurrences attribute to global warming. There are plenty of factors causing global warming, livestock being one of them. People don’t usually consider that livestock could be an element of global warming. To sustain livestock, you need land, water and food, with food comes excretion; by reducing the amount of meat consumed, people should be able to reduce the livestock’s carbon footprint.
The ecological consequences of global climate change are expected to be drastic although not much is known as to how individual species will react to these changes. Irrespective of the causes of climate change, whether anthropogenic or natural, it is imperative that we address these concerns, as they will have widespread impacts on the human species, both directly and indirectly through forcings on other species. The climate is not expected to shift evenly and the ways in which certain species adapt or migrate due to these changes could be erratic and unpredictable. The rate at which the earth’s climate is currently changing is unprecedented and has not been seen in the past 450,000 years. Although many species have simply migrated northward or vertically up mountainsides to escape warming habitats, others do not have this luxury or cannot migrate fast enough to survive. The earth’s temperature has risen by over one degree Fahrenheit over the past century, based on land and sea level measurements. The temperature is expected to continue rising at a faster pace over the next century, possibly increasing by as much as seven degrees Celsius. In comparison, the earth’s average global temperature was only twelve degrees cooler than it is now during the last great ice age. A vast majority of species now living do so within a narrow spectrum of temperature ranges and will not be able to adapt to a warming climate on such a large scale. If humans are the cause of a warming climate we will ultimately be responsible for the destruction of millions of species.
Climate Change is any substantial change in climate that lasts for an extended period of time. One contributor to current climate change is global warming, which is an increase in Earth’s average temperature. Plants and animal species throughout the world are being affected by rising temperatures. Many plants are flowering earlier now than they once did; animals, such as the yellowbellied marmot, are emerging from hibernation earlier; and many bird and butterfly species are migrating north and breeding earlier in the spring than they did a few decades ago, all because of slight changes in temperature cues.

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 the end of the 21st century will exceed the most extreme temperatures recorded in the history (Battistic and Rosamond, 2009). Agriculture is considered to be one of the most vulnerable sectors to climate change. Although at present, the overall impact of climate change on global agricultural productivity is not reliably estimated (Gornall et al., 2010). Many studies show serious implications on agricultural productivity, for instance IFPRI(2009) projects that in South Asia by 2050 climate change will reduce production of rice, wheat and maize by 14%, 44% to 49% and 9%-19% respectively relative to no climate change situation.
Climate change is currently affecting agriculture because it is causing prolonged droughts, violent flooding, sea level to rise, and also health related issues. Droughts and flooding utterly affect agriculture because it damages cultivation since the amount of water applied to crops and farming is fundamental to the...
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 water resources, high food insecurity; encroachment into
