These include volcanic forcing, solar forcing, solar variability and the industrial chemicals. The cause of our current climate change issue is from human beings. Anthropogenic variables is the leading role of climate change today.Climate change currently is caused by the increase of greenhouse gases in earths atmosphere. The increase of greenhouse gases is driven by man made forces. In the industrial revolution the amount of greenhouse gases like Carbon dioxide increased.
Scientists have studies Earth's climate changes for decades, by analyzing many indirect measures of climate such as ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments, as well as by studying the change in Earth's orbit around the sun. This study shows the climate system changes over time over a full range time scales. However, before the Industrial Revolution in the 1700s can be explained climate change by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas concentrations. Recent climate changes cannot be explained by natural causes alone. The study indicates that natural causes are not only influenced our climate change in the 21st century.
Yet the contribution of natural causes to recent climate change is negligible compared to anthropogenic causes. The negative alterations caused by the greenhouse gas emitted by humans have a much more significant impact than natural factors. One of the main natural causes of climate change is natural greenhouse gas emission. The sunlight absorbed by the earth and re-emitted as radiation is trapped by the greenhouse gases, consequently warming up the atmosphere. The increase in temperature itself is a climate change but it also increases probability of draught and prolonged heat waves, hurricanes, and heavier rainfall in certain areas.
Besides, in the 1976–2006 years, many stations revealed statistically significant positive trends at tropical nights, summer days, warm nights and hot days. What causes global warming in Climate Change? • Natural greenhouse effect • Exaggerated greenhouse effect What is a Climate Change? Any change in climate, directly or indirectly resulting from human activity(which alters the overall composition of the atmosphere) and additional natural climate changes over comparable time periods. There are three impacts in the Climate change which are the following below: 1.
The Earth’s climate is an extensive and complex thing. Science has studied it a great deal, but there is still much that is unknown. One thing that is known however is that humans can directly and indirectly affect the climate. One way they do this is by contributing to climate change. Climate change is very real and will have terrible effects if left unchecked.
Climate Change is one of the biggest threats that humanity has to deal with in the 21st century (Papworth et al, 2014). Climate change is referred to by most people as the alteration of the world’s climate caused by humans. According to UNFCCC (2011), it is the change that can be attributed directly or indirectly by human activity that changes the composition of global atmosphere and which is in addition to natural climate variability observed over compatible periods of time. The direct and indirect human actions range from agricultural activities such as cattle ranching, deforestation, mining activities, and combustion of fuel by vehicles to population increase (Markham, 2009). The consequences of these human induced climate change causes are without question.
The issue of climate change has provoked much controversy lately. While some people believed that climate change is simply the natural warming and cooling variations in climate system, it seems that human activity is contributable to that phenomenon, especially to the extent of greenhouse effect. Greenhouse effect is known as a naturally occurring process that aids in heating the Earth's surface and atmosphere. In actuality, it is undeniable that the enhanced greenhouse effect is mainly caused by human activities, including the combustion of fossil fuels and deforestation. The first problem to be elaborated is that the combustion of fossil fuels in industrial activities and transportation directly leads to the increased greenhouse effect.
Global warming has a lot to do with the environment, melting glaciers and raising sea levels. It may also increase the frequency of extreme weather events such as droughts, floods and extreme temperatures, affecting living organisms. Finally, it will affect the global ecosystem. Moreover, I also learned a lot about the natural causes is just one part of climate change. We also need control ourselves, Such as we can control the number of cut down the trees.
Climate Change: There are a number of global problems happening for example terrorism, spread of infectious diseases, poverty, economic crisis, proliferation of nuclear weapons, and increase in armed conflict but none of these problems is much bigger than climate change. I have a strong conviction that Climate Change is a major global problem that possesses the greatest threat to human existence on earth and thus we need to pay a lot attention to this climate change in every part of the world because it is already happening and our weather is in turmoil not by natural events but mainly mankind’s activities. Over most of Earth’s history, natural processes have been responsible for periods of climate change. The Earth 's climate has changed throughout its history long before human activity could have played a role. For example, the planet has swung between cold glacial periods or "ice ages", and warm interglacial periods over the last few million years.
Global Warming Proposal Introduction The phenomenon of constant increase in the earth’s temperature is known as global warming. The excessive use of fossil fuels is destroying our environment as well as wildlife. It is a great threat to human life too, as this activity is causing intense pollution and also results in damaging the ozone layer. Statement of Problem I. What are the causes of global warming?
