Due to the increase in greenhouse gases less solar energy is reflected back into space and more solar radiation is absorbed by the Earth causing the increase in ice and snow melting (Main & Ahlenius, 2011). With this background information the change of climate conditions such as, snow, rain, winds, and temperature is continuously happening all around the world and will continue to worsen in the future. A good indication of climate change is to look at the melting of glaciers and the Polar Regions as the Arctic is one of the fastest warming regions of the world. However, since the Polar Regions are so big and cold it would be impracticable for humans to live and carry out research there. Therefore, by using applications of remote sensing we can easily observe inaccessible areas from satellites to effectively monitor and map snow and ice cover in Polar
Moreover, if we stabilized concentrations and the composition of today's atmosphere remained steady (which would require a dramatic reduction in current greenhouse gas emissions), surface air temperatures would continue to warm. This is because the oceans, which store heat, take many decades to fully respond to higher greenhouse gas concentrations. The rapid increase in carbon dioxide emissions observed during the last 250 years is expected to continue for several decades to come. Various scenarios have been examined, depending on factors like fuel use and efficiency. Even the best case scenario predicts further increases in carbon dioxide emissions until about 2040.
First, the melting of ice caps and glaciers is releasing water into the oceans. Second, human activities, such as the burning of fossil fuels, combined with natural activities, it causes the rise of the earth's surface temperature.3 Second, climate change is already having a serious effect on every continent and throughout the world’s ocean. The consequences of sea level rise mainly reflected in three aspects: cultural heritages, indigenous communities and coastal lands. 4 First, sea level rise threats cultural world heritage. Data shows that 136 out of 700 listed cultural heritages throughout the world will be affected in the long term.
Although the issue did not start to gain national attention until the early 2000s, scientists have been studying atmospheric gases and the effect that human consumption of fossil fuels has on the atmosphere and climate since the early nineteenth century (Rich). The overwhelming consensus among scientists today is that the climate is changing drastically and humans are causing it through specific, preventable actions (Rich). Global warming is caused by an increase in greenhouse gases, which, under normal conditions, it (the greenhouse effect) is what makes life sustainable by keeping the earth within a constant range of temperatures (Gore). About 30 percent of the light and the heat of the sun is reflected back into space, either by clouds, or by the earth’s surface (especially ice, which is particularly reflective.) About 20 percent of the light and heat from the sun is
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.
It would change our climate, but it would not bring us close to the level of uninhabitable Venus. A doubling in CO2 levels would make agriculture much more difficult due to shifts in climate that occur as a result of increasing temperature. CO2 can indeed cause a significant degree of warming if it is suddenly released into the atmosphere, as we have been doing for the past 150 years. Aside from that, increasing temperature can also cause the rising of sea level as the glaciers are going to melt at a faster rate like never before. Next, is the change in environmental health.
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.
The change of temperature in Antarctica due to global warming has had many effects on wildlife and the environment already. Although these effects many not seem big right now, there are many that will progress and continue to change Antarctica’s environment, depending on how the temperature changes. Temperatures have been rising constantly in Antarctica. Last April was the second warmest April in history, only behind the year before that (Waldman). The whole world is experiencing global
Since we have the attention of everyone, now is the best time to take action against global warming. Due to the increasing temperatures every year our public health and our agriculture/food supply is at high risk for new and worse diseases due to global warming; we need to change our climate control policies to protect ourselves. Gases are being trapped inside of earth’s atmosphere like a soda can, and are gradually increasing Earth’s temperatures that ice will start melting and there will be flooding due to rising sea levels; plants and animals will start becoming endangered (as cited in Cooper, 2001). We have already seen coastal flooding in parts of Central America and Bermuda’s forests are now endangered due to flooding (as cited in Clemmitt, 2006). Global warming has been an issue since factories were introduced to this world; gases and toxins are being highly exposed into our atmosphere causing a tremendous reaction to the balance of nature.
“But by 2030, it is estimated world CO2 emissions will be 63% higher than today, as global demand for energy grows.” (Source 5: http://news.bbc.co.uk/1/hi/sci/tech/4216302.stm BBC produced website showcasing an article written by a specialist in environmental issues. Concerning the above fact, that nuclear energy provides CO2 as does the use of fossil fuels, this fact shows that as the world asks for more energy, our energy sources will have contributed highly to global warming regardless of being nuclear or not. It shows that by 2030 carbon emissions will be immensely higher than today as a result of fossil fuels today and existing nuclear reactors.) “1/4 of the country’s (Chernobyl) best farmlands and forests have been poisoned for hundreds of years by Caesium 137 and Strontium 90.” (Source 6: http://www.chernobyl-children.org.uk/disaster.html a website produced by a
