Some of the sun’s energy called the solar radiation is absorbed by the earth, and some is reflected back to the space. A pure layer of atmospheric material absorbs some of this reflected solar radiation, releasing a portion of it to the space, but a big amount of it is forced back to the earth rising its surface temperature. That is where the term ‘greenhouse effect’ comes from. If it wasn’t for this greenhouse effect, the earth’s average climate would be colder. Scientists have done a lot of researches about this matter and recent ones showed that the greenhouse effect is increasing by the release of specific gases to the surrounding that make the earth’s temperature hotter causing global warming.
The Earth normal temperature rose about 0.6° Celsius in the 20th century. There have been legion global warming durations in Earth history. The long effects awaited from the global warming in the 21st century include heat waves, dryness, flooding, sea levels improving, melting of glaciers and polar ice caps, hastiness and temperature irregularity and forest fires. Accordant to the National Resources Defense Council, climate changes will directly influence water supply sustainability profound the United States in future orientate. Here is a simple definition of global warming.
Climate change Climate change, usually referred to as global warming refers to changes in average surface temperatures on earth. Scientifically climate change is due to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere which have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires. Climate change is now affecting every community on every continent, it is disrupting national economies and affecting lives, costing people, communities and countries on a daily basis. People are experiencing the significant impact of climate change which includes changing
Burning these fossils releases carbon dioxide and many other gasses that are directly causing the global warming because these greenhouse gasses increase the temperature of the earth and eventually affect the environment change. Reports and studies notify that during the past 100 years Earth’s surface temperature has spiked up to 0.6 Celsius, and while this might not seem to be a big number but even one-degree increase, can affect the Earth’s surface
Climate change is considered to be one of the biggest threats facing nature and humanity today. It is an undeniable and pervasive crisis that affects every aspect of our lives and future. As the planet heats, climate patterns change and it’ll mean more extreme and unpredictable weather across the world. Many places will be hotter, some wetter, others drier. Of course, Malaysia is not excluded from this problem.
Many scientists believe that our production of carbon dioxide and other greenhouse gases is having a heat effect on the atmosphere and this could be dangerous for the environment and human life (Hansen, 2011). This article will examine the causes of global warming, its impacts and the remedies we can do to combat global warming. Many problems could result from global warming. Increase in average temperatures could lead to ice melting in both polar ice caps and mountain glaciers. Global warming also bring extreme weather events, causes sea level to rise, increases ocean acidification and causes lakes and oceans to warm rapidly than surrounding environment.
Evidence to support that humans are the main reason for global warming is in the book “Global Warming and the Political Ecology of Health” when the text states “The sheer volume of mounting data of diverse sorts has convinced most climate scientists that the global warming, that it is increasingly threatening to human life and well-being, and that it is largely the result of human or anthropogenic activities, particularly since the Industrial Revolution” (Baer/Singer, 3). This means that human ‘activities’ are causing global temperatures to rise, along with the burning of fossil fuels, pollutants in the air, and power/transportation. Most people nowadays have a high carbon footprint that collectively contributes greatly to rising temperatures. To support this,in the book “Global Warming and the Political Ecology of Health”, the authors site from Dessler and Parson, saying that “Many aspects of human society and well-being- where we live, how we build, how we move around, how we earn our livings, what we do for recreation- still depend on a relatively benign reduced and obscured in modern industrial societies by their wealth and technology”(Baer/Singer, 3). This can support the claim that humans are the main cause for global warming temperatures to rise dramatically in the past years.
Global warming and climate change is not region-specific. It spreads all over the world. Climate change occurs when atmospheric temperature increases a lot which in turn causes many different changes to earth. According to Camelia & Răzvan (n.d), the scientists in different fields consider climate changes as a global challenge which can get irreversible results. Since the revolution of the industry, human activities was increasing day by day, during this period, cultivated land, natural resources, forest resources and various raw material is breaking up by human, so as result of that, a lot of greenhouse gases was released and this lead to global warming (Huang & Li, 2015).
The argument of this controversy is “are humans the main cause of global warming?” “In its 2013 fifth assessment report, the IPCC stated in its summary for policymakers that it is “extremely likely that more than half of the observed increase in global average surface temperature” from 1951 to 2010 was caused by human activity. By “extremely likely”, it meant that there was between a 95% and 100% probability that more than half of modern warming was due to humans.” (Carbon brief). Human activities, such as the combustion of fossil fuels are altering the climate system. Another reason how humans affect the cause of global warming are human driven changes, such as deforestation, urbanization, and shifts in vegetation
“The theory of human activity (fossil fuel burning) being a direct cause of global warming is based on the assumption that atmospheric carbon dioxide concentration is directly related to global warming. Is this assumption valid?” Global warming is brought about by the greenhouse effect. The greenhouse effect Gasses in the troposphere cause the greenhouse effect. There is a correlation between the temperature of the earth and the concentration of carbon dioxide in the troposphere, however, correlation does not infer causality. The earth receives energy from the sun in numerous wavelengths.
