Climate Change And Global Change

Climate Change- Climate is a long term change in the Earth's weather, especially due to an increase in the average atmospheric temperature. According to research, it was discovered that the Earth's temperature rose by 0.6 degrees Celsius (C) and predicted that the sea surface temperature may rise by up to 1 degrees C over the next 50 years. Unfortunately, carbon dioxide and methane gas levels are the highest they have ever been for the last 420000 years. These two gases with water vapour, nitrous oxide and halocarbons create the five predominate greenhouse gases, effecting the environment greatly. Furthermore, it is evident that an average person release 4 metric tonnes of carbon dioxide per year. Due to this fact, carbon dioxide

During the past several hundred years, civilization has made rapid progress in industries like air travel, automobiles, and energy production. These developments were made without consideration of the long-term effects that their emissions may have on the planet. Changing weather patterns are now wreaking havoc around the world, and scientists attribute this to human-caused climate change. During President Obama’s State of the Union address in 2015, he stated that, “No challenge poses a greater threat to future generations than climate change,” (“Remarks by the President”). Warming temperatures caused by anthropogenic climate change have disastrous consequences that pose a threat to humanity and the environment.

Global warming is defined as the recent increase in the world 's temperature that is believed to be caused by the increase of certain gases (such as carbon dioxide) in the atmosphere. There are many different theories on whether global warming is similar or not to climate change. Simplistically, climate change is different because climate change is defined as a change in global or regional climate patterns or, in particular, a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels, having been measured over long periods of time, due to the changes in Earth’s orbit and organic carbon which reflect sunlight. Global warming and climate change are not to be confused because global warming is caused mainly by anthropogenic factors like the emission of carbon dioxide gas and use of fossil fuels whereas climate change is completely natural, however, according to Milan Radovanovic, “it is clear that the anthropogenic factors dominate the increasing temperature and the natural ones have the maximum influence…” (Radovanovic). Therefore, “the contribution to global warming from natural forcings and from natural internal variability is in the range between -0.2 to 0.2 [degrees] celsius over the period 1951-2010…” (Radovanovic). Natural factors have had the most effect on global temperature in the past 59 years totaling a 0.4 degrees celsius increase in

Climate change has been an important issue for the past century brought about by human activities. As humans aim at growing economically, environment issues are always been overlooked, especially in some developing countries, like China and India. In other words, it is the trade-off between the speed of economic growth and environmental sustainability. (López & Toman, 2006) Meanwhile, with increasing use of dirty energy source, for example, petroleum and coal, a mass of greenhouse gases is discharged into atmosphere, which would lead to greenhouse effect. And greenhouse effect is the main reason of climate change. Scientists have raised the issue of climate change by providing scientific evidence to show

Climate change is one of the most important challenges of humankind in this century. The ability to adapt, mitigate and reduce carbon emissions will be decisive to preserve the world for future generations. The last IPCC report has provided more evidence regarding the rise in temperature and sea level. Apparently, additional 2°C above the pre-industrial average temperature levels is unavoidable, and it will continue at that level due the accumulation of gases in the atmosphere (Solomon 2009). Climate change will affect people all around the world in different ways, though the capacity to cope with it is different among regions and countries. The Latin America region is notably susceptible to climate change, due its geographical position, population location and its economy relying in natural resources (Vergara et. al. 2013a). The withdrawal of the coral biome, glaciers melting, jungles & forest savannization and strongest climate events are only some of the threats that will affect their inhabitants.

When you hear the words “climate change” what comes to mind? Probably weather and the changes. Many of us watch the news or use an app on our cellphones/electronic devices to keep an eye on the weather for the day, week, or even the month. But, there is actually a difference between weather and climate. Weather is actually “the changes we see and feel outside from day to day. It might rain one day and be sunny the next. Weather also changes from place to place” (Dunbar, 2014). Whereas “climate is the usual weather of a place. Climate can be different for different seasons. Different places can have different climates” (Dunbar, 2014). This paper will focus on the ins and outs of climate change, specifically focusing on what climate change

Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide, Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere make the earth habitable with respect to regulating the earth’s temperature. However, an increase in the concentration of these gases results in trapping energy in the atmosphere and this in turn increases earth’s temperature. “Global greenhouse gas emissions have grown since pre-industrial times, with an increase of 70% between

From the observations presented in the paper it is clear that there is direct/indirect link between extreme events and climate change and the similar observation was found by Seneviratne et al., 2012) supporting that Climate change has resulted in changes in the occurrence of extreme events. Moreover, Out of 24 extreme events analyzed in this paper, 12 showed direct or indirect links to anthropogenic climate change and some could not be explained. Once a change has been detected it is important to attribute that change to some cause. Attribution, especially to human greenhouse gas emissions, gives confidence to model projections of the future driven by anthropogenic forcing as well as predictions of extremes at shorter time scales (Seneviratne and Zwiers, 2015). When an extreme event occurs, the question of attribution of these events to human-induced climate change is of particular interest. Two schools of thought have emerged in this rapidly developing field. “Oxford” quantifies the change in probability of an extreme event of a particular observed magnitude caused by the human alteration of the climate system whereas “Boulder” (NOAA 's Earth System Research Laboratory) examines the human induced change in magnitude of an extreme event. While providing different types of information to stakeholders, both these probabilistic and mechanistic schools of thought have been shown to be equivalent (Easterling et al 2016). But in some cases, some scientists have concluded that a

"It is urgent and the time frame is critical and it has to be right now," said Vicki Arroyo, executive director of the Georgetown Climate Center at Georgetown Law. "We can 't lose another four years, much less eight years" (Neuhauser).

Climate change is a serious global concern of both the public and the governments. With the increase in greenhouse gases (GHGs), mainly carbon dioxide (CO2), and methane in the earth's atmosphere. There is a widespread view that this increase is leading to climate change, with adverse effects on the environment.

A meeting discussing global warming and the ongoing climate change (and the impact CO2 emissions have on the growing problem) has been in session in Peru for the past few days. Dozens of world leaders are gathering to discuss possible changes that can be implemented to halt the increase in temperature seen around the globe. However, many prominent scientists have stated that it may be too late for these world leaders to make any significant impacts (Associated). These scientists, and many other people around the world, believe that humans have contributed significantly to global warming, and as a result mankind needs to do whatever it can to combat this ongoing crisis. Nearly 3,500 miles away from Peru, United States Senator James Inhofe is in Washington D.C., representing Oklahoma in the United States Senate. Senator Inhofe is one of the loudest preachers of the belief that global warming is not the dire threat that so many scientists make it out to be. Inhofe has claimed that it is “arrogant for people to believe human beings are able to change what He (God) is doing in the climate” (Tashman). The Senator believes that only God controls the climate and the environment, and to even think that humans are impacting the earth’s climate is misguided (Tashman). These two opposing viewpoints bring with them questions of religion, politics, human responsibility, and ultimately the fate of the planet. On one side, there are those who say that the science is so concrete, and the

Climate change have become a major problem for the earth. And it could lead to the downfall of the human race. And the question is what causing the climate change. Let examining the greenhouse effect to further our understanding about the climate change. For example, if the greenhouse gas concentration is high it will absorb a great percentage of earth infrared energy emissions. That would lead to more energy getting reemitted back toward the earth surface. And increase the average temperature of the earth surface.

Global climate change refers to the long-term alterations in the world 's average leading weather conditions such as precipitation, temperature, and the wind. In the view of the most authoritative climate watchdog, the United Nations Intergovernmental Panel on Climate Change, the global average climatic conditions are drastically changing due to many factors. The body cites greenhouse gas (GHC) emissions as the primary of all the possible causes. The GHC emissions develop a glass roof that blankets the earth hence tapping and containing the heat that would easily escape to the space (Bradley, Keimig, Diaz, and Hardy). The assessment of global climate change relies on the changing precipitation and temperatures. Even

Energy is a huge part of our daily lives and over the years we have seen energy consumption rates raise significantly. It really isn 't much of a secret that global climate change is happening. From the melting of the polar ice caps, to record severe temperatures, rise in natural disasters, rise in pollution, greater number of vector-borne and water borne illnesses, and much more. Unless there is something done to change the current technology being used to provide energy to the human population global climate change will only continue to get worse. Climate change is the biggest global health threat of the 21st century and we must act and change the use of energy technology and oil for our sustainable future.

The environmental security is one of the biggest concerns for human society in these days as stability and natural resources preservation have become essential elements of international relations and domestic security. By looking to the current situation of global environmental security, it seems that the rate of destruction to the world’s environment by humans is increasing and the damage is faster than it can be recovered (Fiona Harvey, 2016). There are many factors which play a fundamental role in destroying the global environment. The most visible one is the human’s incorrect activity that resulted in climate change which can be viewed as an enormous threat to environmental security. It is believed that the current local and global climatic changes have been impacted by the increase of greenhouse gases emissions which may effect on reducing the food and water as they are the main elements for environmental and human security. This paper gives an outline of the theory and practice of global climate change and a brief history of the international negotiations on the issue done by United Nations and argues how successful they have been. Then it reviews the impact of climate change on Australia’s environment and explains its national polices and international commitments, as well as the role of both USA and China, the largest contributors in emitting carbon dioxide into the atmosphere, in reducing the greenhouse gas emissions. At the end it explains the way in which
