During the 20th and 21st century there has been growing concern about CO2 emissions and their toll on the environment. Human activities have largely increased the amount of greenhouse gases in the atmosphere, particularly CO2. With the increase in greenhouse gases, the temperatures on Earth have risen due to the gases’ ability to trap of heat. This increase in temperature has had many detrimental side effects on ecosystems. For instance, global warming has resulted in the melting of ice in the southern and northern latitudes, destroy valuable habitat and creating strain on the organisms that live there (Frolicher and Joos, 2010). A result of this melting of ice in the higher latitudes has caused sea levels to rise. Furthermore, with more emissions of CO2 there has been greater absorption of CO2 by the oceans. When CO2 is in the ocean it reacts to produce carbonate ions and H+ ions leading to ocean acidification. Major effects of ocean acidification are already being seen; mollusks, coral, and echinoderms that have shells composed of calcium carbonate are eroding away due to acidification (Kerr, 2010). Ocean acidification, climate change, habitat loss, and extinction of species will continue if there is no change in CO2 emissions. Such changes could be catastrophic on fragile ecosystems. According to the Environmental Protection Agency, the top contribution to increased CO2 levels is burning of fossils fuels for electricity, heat, and transportation. It
Other species are being affected by this global warming. Especially, the animals that survive on ice like polar bears. Impacts of global warming include the melting of ice in the Antarctic; this is due to the rising temperature of the ocean surrounding the ice which then causes melting. However, some people argue that the ice caps are growing rather than shrinking so they completely devalue the issue of global warming. This is not necessarily true, since the heat from the ocean causes the ice to melt but the melted ice (turned into fresh water) also freezes immediately after it melts. So it is still an issue that is supposed to keep an eye on. The ecological impacts of ice melting would be the reduction of small ice caps which polar bears land
Every living organism in the world needs water to survive. Unfortunately, the world has a continually diminishing freshwater supply. With the severity of global climate change and the continued increase in population, the outlook for freshwater ecosystems is bleak. Numerous steps have already been taken to solve the water scarcity problem but the methods being used are not getting the job done. These methods include wastewater recycling, desalination of seawater, and harvesting rainwater. While these methods are helping water scarcity, they cost millions of dollars and are only temporary fixes. Something has to change or human beings are going to run the world dry. Instead of throwing money and resources at creating new technology to
“Global warming is the term used to describe a gradual increase in the average temperature of the Earth 's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate” (Goguen). Day-to-day, fossil-fuels are being burned; humans are deforesting land, driving cars, creating and demolishing buildings, and much more; these activities result in the release of greenhouse gases (Goguen). Architects are now being awakened by global warming issues and are planning ideas to alter their designs to reduce carbon emissions for future buildings. Correspondingly, colleges are beginning to prepare architecture students on how to design buildings that are carbon-neutral, and educating them on the
What is Global Warming? Countless feel as if it is a natural phenomenon that the Earth cycles through. They are terribly mistaken. It is the effect of greenhouse gasses that are emitted by the machines we use today. These gasses are becoming trapped in the earth’s atmosphere, causing the temperature to rise. The effects of global warming are all around us and are becoming more prominent. There are already efforts in place to stop it and programs to “go green”. This climate change is a serious threat that needs to be addressed. How can a person live on an earth that is too hot to be habitable?
Global warming is the steady increase in the Earth’s average surface temperature. There are two sides of this story. Some people believe that global warming is caused by natural components in the environment and not man-made production of carbon dioxide, while the others believe that it is caused by man-made production of carbon dioxide and not by natural components in the environment. Global warming is due to the increased level in temperature of a climate which is certainly not proven that the humans are the cause of this global warming effect. To the ethos approach, this documentary The Great Global Warming Swindle by British television producer Martin Durkin presents a number of respected scientists, economists, politicians, and writers who dispute the scientific consensus regarding fictitious global warming. According to the narrator “The earth’s climate keeps on changing but there is nothing unusual about the current temperature and the scientific evidence does not support the notion that the climate is driven by CO2 man made or otherwise.”
In modern society, we are surrounded by a plethora of advertisements, and the problem with the ad overhaul is that most of them do not serve a purpose other than to sell merchandise to the consumer. But what if more advertisements focused on real-world issues? Issues such as global warming and the impact humans have on the environment. An advertisement by Legambiente does not try to sell you anything. Instead, they target the world to disclose the truth behind global warming. Alongside Legambiente resides Greenpeace, trying to get the world to realize the damage we cause to the oceans. These advertisements are trying to help change society 's attitude and understand that humans have a horrendous impact on the environment. Society needs to make a change in its daily habits if we want to have a planet to live on.
Human impact such as industrialization, livestock farming and the increase in recent population have all caused serious environmental impacts that have let to dramatic global climate change. “Scientists generally agree that the globe has warmed over the past 40 years, due largely to human activities that raise carbon-dioxide levels in the atmosphere” (Clemet). Greenhouse gasses have always existed, but not to the extent that they do in today’s world; they are causing a dramatic change in climate and causing major environmental issues. Although some may argue the fact that climate change occurs naturally and humans have no impact on the speed of climate change, humans are dramatically increasing the rate in which our seas rise, our ice
How would the population of the world appreciate it if the Earth got relentlessly hot in a matter of time? Well, this is global warming. This outrageous heat increase is something many think is microscopic and harmless, but it could change the Earth immensely in a matter of time. Made by human activity,global warming, including the burning of fossil fuel, and blazing down forests. Yet scientists can detect how much the Earth’s temperature is increasing, but countries can fix these problems by not depending on natural resources so much, reusing energy, and setting policies for climate change to help the public regulate it.
There is no doubt that global warming becomes one of the most dangerous, serious and popular issues in the 21st century. It is possible to identify the probable and effective solutions by means of the population around the world to reduce negative effects on our planet. Joseph and Roy (2014) points out 97% of the scientists and professionals are trying to discover the best explanations, which can prevent our world from violent disasters that can damage the lives and wealth of all nations and animals. This essay will consider how global warming worsens day by day, the consequences of global warming and the solutions to overcome it.
Global warming is an increasing in average global temperatures across the planet. This is due to the rising temperatures on the continent. Temperatures continue to rise yearly causing global warming. The greenhouse effect is sun light radiation being driven back to the earth. When solar energy is released into the atmosphere, there is an effect of bouncing back. Solar radiation is bounced back into the atmosphere causing the temperature of the earth to remain steady. However, over time greenhouse gases in the atmosphere have caused the bounce back solar radiation to have a double back. This is when the greenhouse gases in the atmosphere cause the solar radiation to bounce back to the earth forcing the temperature to rise and remain higher than normal. This in effect causes global warming to occur. The atmospheric temperatures rise because the solar radiation is not escaping the atmosphere like it is designed to do. The two work hand in hand. Atmospheric temperatures are being pushed to higher levels because greenhouse gases in the atmosphere are at an all-time high. The greenhouse gases in the atmosphere cause the solar radiation to push back to the earth, in return raising the overall atmospheric temperature of the earth. There are several different types of gases in the atmosphere that cause solar radiation to bounce back to the earth keeping it trapped in the atmosphere. These gases are vital to the earth because if there were no gases the earth would freeze. The overall
On April 11, 2014, Cyclone Ita roared through Queensland, Australia leaving a trail of destruction in its wake. One of the strongest Category 5 storms ever recorded, winds were recorded at over 110 miles per hour before landfall. While destruction in Queensland and the surrounding areas was immense, the offshore damage to the Great Barrier Reef was catastrophic. Many places of the reef were left with no living coral structures and entire portions of the ecosystem were erased from the seabed (Zolfagharifard). Scientists explain that we can expect more intense storms such as Ita in the future, explaining that “warming is expected to make tropical cyclones (hurricanes) more intense” (Weeks). Global communities cannot ignore the warning any longer and must take action to reduce further climate change.
The temperature was taken at each of the sites to determine the heat of the water. The temperature of the water affects the dissolved oxygen as well as the rate of photosynthesis and the metabolic rates of water life. (Hovey, n.d) Warmer water can hold less dissolved oxygen and plants grow and die more quickly. Therefore it can be deduced that cooler water allows for a more comfortable environment for animals and vegetation.
One of the more troubling themes of over the past few years is global warming. Global warming is the result of human activity overloading our atmosphere with carbon dioxide and other toxic emissions. These emissions trap heat, drive up Earth’s temperature, and create significant and harmful impacts on our health, our environment, and our climate. In an effort to hinder global warming, advocates have made several efforts to decrease the amount of harmful emissions being released into the atmosphere and have put pressure on the government to be involved in the fight against global warming. The U.S. Federal Government responded by making certain atmosphere-harming actions illegal and providing incentives for individuals and companies to
If you look at our planet in the 1950s you would see that the continents Europe and North America would be 4 feet closer together. There would also be 2/3 less humans as there is now on Earth., earth, twice as many trees covering the land and, three times as muck drinking water available to us. Another reason of future human extinction is coming is the rapid climate change. The rapid climate change is causing the Arctic ice cap to melt at a fast pace. The human race would become extinct by over population, more devastating natural disasters, along with continents converging together.
As technology continues to advance, and as the population continues to grow and the individual life expectancy becomes longer, the global environment is being negatively impacted by various human and natural activities that are detrimental to the environment. Unfortunately there are many global environmental issues that need the attention of world leaders today, and have become undisputed environmental issues in today’s society. However, the most important public health, environmental issue I would like to address in my discussion is global warming. Furthermore, global warming influences a great amount of climate changes in the global arena. Hence, its befitting to say that, most issues associated with climate changes around the world and global warming or increased atmospheric temperature are intertwined.
