Causes And Effect Of Temperature Essay - 5322 Words

3. Impacts of elevated temperature Increased greenhouse gases causes increasing global mean temperature. Global mean temperature will increase by 1oC above present value by 2025 and by 3oC by 2100. In temperate latitude, temperature rises will causes increased photosynthesis and respiration of plants. Rising temperature shows respiration increasing more than photosynthesis. It causes an autocatalytic component to global warming. High temperatures limit growth, development and ultimately adversely affecting crop yield. Detrimental effects of high temperatures have been observed during both the vegetative and reproductive stages of various plant species. However, reproductive stages are most sensitive to high temperature stress compared to vegetative stages. High temperature induced reduction in the crop yield is attributed to the negative effects of high temperature stress on cell structures and physiological and metabolic processes. High temperatures disrupt the integrity of cellular membranes and cause changes in enzyme activity that lead to alterations in the rates of biochemical reactions and ultimately an imbalance in metabolic pathways. The molecular basis of high temperature damage involves changes in protein conformation (Berry and Bjorkman 1980; Levitt 1980; Larkindale et al., 2005). Plants may be exposed to severe high temperature stress during germination, which can cause loss of vigor, ultimately leading to reduced emergence and seedling establishment.

Essay1724 Words   |  7 PagesAbstract The purpose of this article by Diffenbaugh et.al. is to determine how temperature increases due to anthropogenic warming change the probability of precipitation deficits that cause severe drought conditions, and determine what the conditions will look like in the future. They used historical precipitation and temperature data with Palmer Drought Metrics and global climate models to attempt to answer this question. It was found that in the past twenty years, the frequency of drought yearsRead MoreThe Effects of Global Warming on the Earth990 Words   |  4 PagesGlobal Warming Earth’s temperature is a vital aspect to Earth and its surroundings. The atmospheric temperature along with natural gases is the significant reasons why Earth inhabits all of its life. When there are changes that alter the natural affects of Earth’s environment there are factors that places the environment at risk. Increase warming of global temperatures account as a major concern of Earth’s surroundings. Global warming is a prominent source to consider how and why the environmentRead MoreThe Effect Of High Skin Temperature On An Individual s Performance805 Words   |  4 PagesHowever, there is still so much research understanding the cause of this. The experiment conducted by Hettinga et al discusses the idea that an individuals output can be influenced by hot temperatures leading to fatigue and exhaustion. This experiment also explored the idea that an individuals increase in skin blood flow could also explain individuals decrease in their performance [2]. M any others have explored this idea in cycling and the effects that cycling intensity can have on an individual’s performanceRead MoreIn the last 100 years, Earth’s average temperature has risen by 1.4 °F. The rising global900 Words   |  4 PagesEarth’s average temperature has risen by 1.4 °F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise fromRead More Global Warming Essay1614 Words   |  7 Pagesare global warming and the greenhouse effect. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What d oes the greenhouse effect have to do with global warming? When humans release gases into the air, the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer, and the result is global warming. On the other hand, if there was no greenhouse effect, the earth would be too cold for humansRead MoreThe highest mortality rate in trauma patients with massive haemorrhage initially develops with1600 Words   |  7 Pagescomponents of â€Å"the trauma triad of death†(Anthony et al, 2005) and in lieu of this fact, it is important to ascertain the role of temperature on maintaining homeostasis. With this in mind, an experiment to investigate how the temperature of clotting chemicals affect blood coagulation in the circulatory system, specifically in the cases of hyperthermia and hypothermia, and the effects on homeostasis within the body, will be performed. Human homeostasis according to Marieb et al (2007) refers â€Å"to the body’sRead MoreGlobal Warming: A Human Cause? Essay1646 Words   |  7 Pagesresearch has proven that humans are not the sole cause of global warming. In fact, some scientists say that the natural causes of global warming far outweigh the human causes. What exactly does global warming effect? The effects of global warming are spread across the entire world and can be broken down into three main areas, the first of which is heat waves. Heat waves are defined as periods of time lasting more than three days at which the average temperature exceeds 90 degrees Fahrenheit. AccordingRead MoreGlobal Warming And Climate Change1713 Words   |  7 PagesDefining the Issue Global warming is defined as the recent increase in the world s temperature that is believed to be caused by the increase of certain gases (such as carbon dioxide) in the atmosphere. There are many different theories on whether global warming is similar or not to climate change. Simplistically, climate change is different because climate change is defined as a change in global or regional climate patterns or, in particular, a change apparent from the mid to late 20th century onwardsRead MoreEssay on The Great Debate on Global Warming1502 Words   |  7 PagesThe cause of global warming has been a debate between scientists and experts for numerous years. In fact, Svante August Arrhenius, a Swedish chemist, first predicted global warming would occur in 1896 (Harris 16). Researchers who agree it is naturally caused insist the greenhouse effect has many natural causes. Others agree that the cause of the Earth’s increase in temperature is just part of a continuous cycle. These res earchers argue that solar activity plays a huge role in the issue of globalRead MoreGlobal Warming766 Words   |  4 Pagesrelative to the atmosphere, temperature and so on.
