Taking a Look at Global Warming

Global warming is hot topic nowadays. Alarmists and scientists fight to make their statements known, but while the alarmists avoid the scientist, non-governmental organizations pass themselves as scientist. They not only give out exaggerated data, they also have the nerve to accuse humans of being the cause of global warming. Also, we cannot be certain that we are being told the truth without knowing exactly what is really going on behind the scenes. We blindly trust those in authority because we think that they have our greater good in mind and that whatever they say must be the truth.

Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009,

Co2 also has many beneficial attributes to our environment. Carbon Dioxide is one of the most important gases for our plants “some scientists have argued that, until quite recently, many plants were starving for CO2” (Mathews Jr, NPA). And saving the plants is crucial. Not only to help regulate our environment but also because we live off these plants. They are our food; they clean our air. Bigger, healthier plants are grown with the help of Co2 “Increased atmospheric carbon dioxide doesn't just make a plant bigger. Carbon dioxide also makes plants more resistant to extreme weather conditions.”

Global warming is a huge concern in society that is only growing bigger because people either are not well informed about it, or they are not concerned about it. Some think that it will just go away and others still believe that it doesn’t exist, even though there is hundreds if not thousands of pieces of evidence that supports otherwise. One of the biggest pieces of evidence that proves global warming is real is the effect that photosynthesis has on global warming.

CO2 diffuses from the atmosphere into leaves, via., stomata into mesophyll cells, intercellular spaces, cells, and finally reach chloroplast for photosynthetic process. Increasing CO2 concentration in the atmosphere will enhance the photosynthesis and dry matter production. The response to CO2 varies among species mainly by the enzyme RuBisCo (RuBP). C3 plants readily react by increasing the activity of RuBP carboxylase and by reducing the activity of RuBP oxygenase. Increase in photosynthesis by 25%-75% was observed over doubling of atmospheric CO2. C4 plants show little response to elevated CO2. Crassulacean Acid Metabolism (CAM) plants also showed an increase in photosynthetic rate. The increasing concentration of CO2 by burning of fossil fuels can be reduced by improving the carbon fixation in the plants. Short-term exposure of CO2 on plants shows increased photosynthesis, whereas long-term exposure shows variation in photosynthesis and also plant growth.

Global warming presents a huge problem in the world today, but not every scientist believes this. They think that the weather is just supposed to change naturally. If you look around there is evidence to support this theory. The sea level is rising, the global temperature has become warmer, the oceans are not as cold, and the Arctic ice has begun to disappear. Greenhouse effect and the depletion of the ozone layer also contributes to Global warming. There are many predictions about Global warming, the Greenhouse effect, sea level rising. Scientist have various predictions on how life on Earth will change by the year 2100.

If we are going to look at the consensus on climate change we should start by defining which group of people is supposed to be reaching that consensus. All scientists are supposed to know all there is to know about every field of science; 17,000 scientists signed a petition saying there's no convincing evidence that greenhouse gases will disrupt the earth's climate; 31,000 scientists are saying that global warming is beneficial. A lot a meteorologist become weather forecasters or pilots or teachers or homemakers or businesspeople. There are no longer Geophysicist who specialize in measuring seismic and magnetic anomalies. So the petition suggestion that everyone with a degree in meteorology or geophysics knows a lot about climate change or is familiar with all the research that's been done. Phil Chapman was described as a geophysicist when he wanted to promote his thoughts on climate but his bio on NASA's website shows that he was a physicist who specialized in aeronautical instrumentation. Tim Ball has a variety of titles 28 years professor of climatology at the University of Winnipeg, 32 years as Professor of Climatology at the University of Winnipeg, a former climatology professor. Professor Tim Ball of the Department of climatology at the University of Winnipeg; first of all there is no climatology department at the University Winnipeg, climatology was just one small element of the geography course that you taught your major was in geography and you were geography

The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.

High atmospheric CO2 has become an environmental concern and will always be unless we change our ways of life. Discussions concerning this topic end up pointing nothing but that regardless of all the other indicators indicating that we are actually doing better, unfortunately that is not good enough, we need a dramatic change in our current lifestyles because the life we currently are living in is the biggest contributor to this observed atmospheric CO2 levels. We should and are afraid that the consequence of the elevating atmospheric CO2 which is global warming could eventually destruct our ecosystems and the vital services they confer. About 80% of the additional atmospheric CO2 is a result of oil, gas and coal combustion mainly by industries and the remaining 20% is a result of alter ecosystem in a form of deforestation, thus disturbing the fixation of this gas in plants (IPCC 2007).

Increased temperature plays a role in the amount of liberated carbon dioxide (Wan and Luo, 2003), and because cellular respiration is a metabolic reaction, increased temperature will increase the activity of decomposers, releasing more carbon dioxide. To promote a sustainable environment and optimum plant health, it is critical to be aware of the range of temperatures suitable for adequate soil respiration. If

The environment changes over time, causing plants to respond to these changes. The increasing concentration of CO₂ in the atmosphere has a significant impact on plant function and the climate. Therefore, it is important to discover how plant behaviour will be impacted as the concentration of CO₂ changes, as the concentration of CO₂ is directly related to the

Climate change and variability poses a major challenge to current and future productivity of major crops. During the last century, there has been a rapid increase in various greenhouse gas emissions, leading to warmer temperatures, drought stress, and increased exposure to ultraviolet-B radiation. At the present rate of population increase and green-house gas emissions it is predicted that future climate will be warmer and drier, and there will be more occurrences of short episodes of extreme events of various stresses. Crops often exposed to short episodes of various abiotic stresses or its combination during its critical period of growth stages can limit its yield potential. Understanding of impact of climate change drivers and climate variability will be critical in developing crop management strategies to combat negative effect of climate change and variability. This review provides an overview of the influences of elevated carbon dioxide, high temperature stress, drought stress, elevated UV-B radiation and their interaction on various physiological, growth and yield processes of various crops. Elevated carbon dioxide will increase crop yield in C3 plants under optimum growth conditions. However, under high temperature, drought and UV-B stress conditions there will be very limited or no benefits of elevated CO2 on grain yield. It is predicted that global mean surface air temperatures will increase in the range of 1.5 to 4.5°C by end of this century. Similarly,

With the increasingly serious problem of global warming, Australia’s climate has warmed since 1950. ("State of the Climate 2014: Bureau of Meteorology", 2016) Compared with air conditioners which required for high cost, electricity expense and health hazard (under an enclosed environment, there has poor air circulation and air quality which would have negative effect for human body. Moreover, without appropriate maintenance, some particulate matter such as bacterial, pesticides and allergens can enter houses from outside environment which will cause health problems.) (McCarthy, Ludwig, Brown, Vaughn, & Roberts, 2013)

Is global warming being accelerated as a result of human interaction? This question has been asked over and over again since global warming was first noticed and brought to our attention. Multiple claims have been made that this anomaly is caused by human interference with the planet. There are also those that strongly deny these accusations. To detect the truth, one must explore both sides of the story. Studies have been done by countless experts to support their side of the story; therefore, that is what has to be examined.

The topic I selected was that of global warming. So far, I seem to want to change my thesis everyday; but this is how it stands for the moment. Americans need to work together as well as with other nations to take immediate action to reduce our environmental footprint in efforts to reverse or cease global warming. I feel this thesis clearly states my position, as well as the point of the paper. I still want to play around with the wording, especially at the end of it. I feel that global warming is a serious issue that should be addressed directly by not only the U.S. but by other nations as well. While there are several groups and movements dedicated to this cause not much has been done. This is why there continues to be groups, events and movements to try to bring attention to the issue. I feel the American government needs to step in to make everyone take the issue more seriously.
