Polar bears may disappear as the sea ice continues to melt. Thus, scientists intend to figure out why the global temperatures have risen, but that thus far they have not found the solution for global warming. A few scientists think global warming is natural; however, the majority of plentiful scientists think global warming is manmade because of emissions from transportation, air conditioning and
Global Warming, a Manmade Problem? Global warming, by definition, is the increase in the ocean and near-surface temperatures. Over the past few decades, there have been debates regarding whether global warming is real, whether it can be reversed, and how it is caused. Through research, scientists have discovered that global warming is, in fact, a real issue that is caused by increases in greenhouse gases (David). Now that global warming has been studied further, there is still debate over whether the increase in the greenhouse gases are caused by natural sources, such as volcanoes and forest fires, or if it is caused by man-made practices such as emissions from driving automobiles (David).
I will be covering the aspects, causes and effects of Global Warming. There are many definitions of Global Warming. One of these is that “ Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate.”(EPA) The temperature increase can lead to changes in the average rainfall results, the sea levels can rise, and it may have many impacts on wildlife, plants of humans. The Global Warming is mainly cause by humans. The Green House Effects is one of the main causes of this warming.
The definition of a crisis is as follows: any unstable and dangerous social situation that affects large numbers of entities. With this definition it is hard to believe that many consider global glacier melting not to be a crisis at all. As technology continues to develop and uncover mysteries and facts, people around the world are starting to realize what glacier melting is doing to the earth. Human activity, be it manufacturing or the use or fossil fuels, has started heat up the world and will spell the eventual end of glaciers. Like any story in the media it started out small when people started to realize what we were really doing as people who are a part of the modern consumer society.
Yes, our earth is currently warming up, but who says this is a bad thing? Evidence has shown that it will be beneficial as it has in the past. Humans believe that they are significantly affecting the earth’s climate when it is most likely natural astronomical and earthly cycles. Really, through all of this substantiation, it may be confirmed that human activity does not bring about global warming and global warming is not a threat. Table of Contents
Some of this long wave terrestrial radiation travels upward, where it may be reabsorbed by other gas molecules. The remainder travels downward and is again absorbed by the earth. Thus, the earth’s surface is being continually supplied with heat from atmosphere as well as from the sun. These processes that take place between the earth’s surfaces will keep the earth average temperature warmer than it would otherwise be. Plate tectonics could also led to climate change.
Natural Causes of Climate Change The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean current, the earth’s orbital changes and solar variations. Volcanic eruptions - When a volcano erupts it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere. Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. Tiny particles called aerosols are produced by volcanoes. Because they reflect solar energy back into space they have a cooling effect on the world.
Causes and Effects of Greenland’s Ice Melt Scientists have been in debate for years over the existence of global warming, arising on the forefront of scientific concern at the turn of the century. Recently, however, many have been unable to deny the existence of the continual warming climate worldwide, and humans have been the cause. Greenhouse gases, which we continue to admit (ignoring the warnings from scientists) trap the sun’s heat and cause the glove to heat and a level faster than any before. Who cares? Global warming not only affects the darker suntan you get each summer, but the winters, the sea level, and the natural environment delicately teetering on the current balance of temperature.
Texts construct race as a natural category. Many representations generally describe the interests of dominant groups by defining other races as abnormal. Somewhere right now, there is someone being discriminated for the colour of their skin. Today’s society; you may say all you want about it being better than what is was like in the 1900’s to now but how much better is it really? Yes we have found many cures for severe illnesses and are now aware of Global Warming, which we are doing our best to prevent with renewable energy, but has anyone ever thought of the way people act throughout society?
Global warming has been a highly debated topic for quite a bit of time now. Is it or is it not happening? Global warming is an increase of temperature that causes related changes in climate and the environment. This has been seen in Antarctica especially. The change of temperature in Antarctica due to global warming has had many effects on wildlife and the environment already.
