These three studies investigated the effects of climate change, and in particular increased temperatures in intertidal zones. The study conducted by Bertness et al worked to quantify thermal stresses on rocky intertidal organisms. The species that was focused on was Semibalanus balanoides at sites north and south of Cape Cod. The team analyzed the relationship between thermal stress, population density and individual organism survival rates. While the study conducted by Bertness focused on increases in environmental temperatures, the study conducted by Helmuth and his team investigated the effect of increased global temperatures on the body temperatures of organisms, which is ultimately capable of altering their physiological activities and functioning. The team used a heat budget model to collect data in relation to mussel body temperature at three different tidal elevations along the coast of California, all of which are also exposed to different ambient temperatures, light intensity, wind patterns, waves, and tide timing. The study conducted by Barry et al also investigated intertidal communities, but focused on the range shifts of intertidal species between 1931 and 1933, as well as 1993 and 1994. It was noted that species shifted their ranges northward, which is consistent with global warming models and other studies that have observed range shifts in recent years. Forty-five species were investigated within California intertidal communities. Along with this presented
Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).
floods, and droughts. All of these relate to climate change and how the world’s atmosphere is heating up. Some floods happen when sea levels rise. When sea levels rise it’s usually caused by the melting ice caps. The reason ice caps melt is because of the heating up of the atmosphere.The main reason the atmosphere heats up is because of the greenhouse effect is caused by the use of coal, oil, and other unusable energies. When these energies are used, they emit greenhouse gases which heat up the atmosphere thus melting the icecaps. In turn, multiple cities near the coast would “disappear” getting submerged in water.
Currently chaired by Mr. Rajendra Pachauri, this organisation was setup in 1988 by two United Nations organizations, the World Meteorological Organisation and the United Nations Environment Programme. IPCC reports on the scientific, technical and socio-economic information needed to understand the
“You are what you eat.” We’ve all heard the old saying, reminding us that what we take in, we can’t help but manifest. A similar axiom might apply to other things we take in, like information. Granted, “you are what you read, hear, and/or watch” just doesn’t have the same ring to it, but it’s operating along the same lines.
Climate change is caused through the increase of greenhouse gas emissions within Earth’s atmosphere. Through trapping sunlight, temperatures have risen over the past years thus being called climate change. However, through things like being energy efficient or changing aspects within daily life climate change can be lessened. Reducing gas emission both in peoples own life as well as world-wide is also an important response to reducing the effects of climate change and it is also important to be involved in organizations for the environment in order to help promote climate change.
Should the studies on climate change possess validity, then numerous human activities have altered the atmosphere of the Earth for the worse. Several among these activities categorize under the macrocosm of transportation. As a species, the human race continues to create and produce, which may contain threatening consequences based on these reports. Inside the category of transportation, every subcategory seems to partake in this, including automobiles, aircrafts, shipping, and railways, among countless others. Fortunately, various people and organizations have attempted to decrease the emission of greenhouse gases, or GHGs, in transportation-related technology and energy. When it comes to paying for these eco-friendly additions,
The model used in this paper deals with the role of CO2 emission in terms of energy consumed, the various parts of economy that deals with energy consumption and which form of energy is and has been predominantly responsible for energy related climate change. Not just that, this model also discusses about the policies and possible solutions for these problems. Different graphs and charts are also used to show the energy usage empirically. We also study the data to analyze the existing problems, their causes, outcomes and the way out of these problems.
The global climate system is complex and its response to future anthropogenic greenhouse gases and to climate change adaptation, is often poorly understood. Climate change is an area where modeling in the framework of complex adaptive systems can improve our knowledge both with respect to the internal structure and adaptive mechanisms of climate and our capacity for designing efficient climate adaptation policies. Modeling of these systems includes a dynamic system consisting of transition equations describing the evolution of state variables characterizing the natural system, such as CO2 concentrations in the upper and lower atmosphere and in the oceans, and state variables characterizing the economic systems, such as physical capital and knowledge. The complex adaptive character of the system implies that the dynamic system will be nonlinear and nonconvex, will allow for nonlinear feedbacks and multiple basins of attraction, will evolve both in the temporal and spatial dimension, and will be influenced by forward looking optimizing economic agents (Xepapadeas, 2010).
In the process of human history, because of the greed of human nature, abuse the science and technology, world environment and resources have been severely damaged. And causing Global climate change, and the resulting related hazards. Global climate change is just an indisputable fact. Do you felt the climate changes? We have been from climate change to feel some strange this year. Global warming is the main features of climate change. According to the evidence that the general trend of global warming is not stopped, not counter attack, is mainly the temperature rise caused by human factors, this change will affect people and other aspects of the earth, has a direct influence and harm to our survival, and measures to prevent global change.
For decades now, global warming has been a recurring issue. The term “global warming” first appeared in geochemist Wallace Broecker’s 1975 Science magazine article, “Climatic Change: Are We on the Brink of a Pronounced Global Warming?” and since then dozens of more studies have evaluated the effects of the global warming. But what is global warming? Well global warming is the effect of greenhouse gases on the earth’s surface temperature. Greenhouse gases are gases like carbon dioxide, methane, and nitrous oxide that become trapped in the earth’s atmosphere. These gases raise the earth’s temperature. Human activity on earth, such as the burning of fossil fuels, add more gas to the atmosphere and excessively warm the planet. The US, being only one country, cannot stop global warming alone, but it can and should do its part to reduce emissions. However, we cannot just immediately stop all emissions. The main obstacle between us and a green energy economy is economics. Most of the energy sources we use either emit a large amount of CO2 and/or Methane or they are not economically feasible to switch to. Solar energy, however, maybe be the one energy source that can both eliminate emissions and provide energy to the country at a cheap price.
As climate change and global warming remain some of the most debated topics in the contemporary social and political spheres, there is need to establish the leading causes of these global phenomena. To date, climate change scientists have differed on the causes of climate change, with one faction holding that climate change is natural and another one arguing that human activities are the primary drivers of climate change (Crowley, 286). More recent studies have embraced a softer stance on the climate change debate by concurring that both natural and human events contribute significantly to increase of the earth's average temperature. Nevertheless, the ongoing discussion of the causes of climate change raises severe concerns since life on planet earth depends heavily on the energy that comes from the sun. Usually, some of the heat that comes from the sun reaches the earth, where it is absorbed by greenhouse gases to help in maintaining a life-supporting temperature. About 10% of heat is reflected back to the atmosphere before reaching the earth's surface (Ball, 279). The change in climate, which is also popularly known as global warming, is as a result of excessive heat being trapped in the earth's atmosphere.
It is obvious that climate change is real, and humans are having an inordinate impact on the natural processes of the earth. This impact is leading to changes in the storm system of the Atlantic Ocean. The increase in overall global temperatures is leading to an increase in ocean surface temperatures. When looking at the process of hurricane creation, it is clear that this increase in temperature will affect the creation of tropical storms. Warmer oceans create more intense hurricanes. Also, historical records provide definitive proof of an increase in hurricane activity in the Atlantic. Over the past few centuries, increases in size, intensity and rainfall have been detected by thousands of scientists. Scientific models such as those created by the IPCC (Intergovernmental Panel on Climate Change) suggest an increase in intensity of tropical cyclones due to anthropogenic changes. These changes are detrimental to society and are a direct consequence of human induced climate change. If climate change continues to worsen, so will the intensity and effect of tropical storms. The increase in sea surface temperature due to human activity is unquestionably contributing to an upsurge in intensity of tropical storms and hurricanes.
What really causes climate change? Is it human cause or is a natural process that is happening? I think that us as humans contribute more to climate change then natural causes.
Warming of the climate system is unequivocal. Since 1950’s many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen. Additionally most of these climate changes are due to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate. The signal of climate change include rise of sea level, surface temperature rise ,glacier retreats, shrinking ice sheets, warming of ocean ,declining artic sea ice ,increase in Antarctic sea ice ,increase in extreme events ,decrease in the amount of snow of snow and ice ,increase in concentration of CHGS.Each indicator described below has been extensively studied over the past several decades, and was captured from many different data sets and technologies.
Climate change is caused mainly by increase of human activity and industrialisation. For example, activities such as driving cars, farming, burning coal and cutting down forests produce greenhouse gases – mainly carbon dioxide, methane and nitrous oxide which are emitted into the atmosphere, which create a layer of greenhouse gases around the earth and trap the sun 's heat.
