Climate Change Impacts on Marine Ecosystems

Questions: 1. Climate Change? 2. Believer part of the Climate Change Paradox? 3. Non- Believer Part of the Climate Change Paradox? 4. Adaptation and Migration Actions to Avoid the Ultimate Impacts of Climate Change? Answers: 1. Climate Change 1.1. Definition Climate Change refers to the change in the statistical distribution of weather patterns when that change lasts for an extended period. Climate changes mainly focused towards the change in the average weather conditions, or the time variation of weather around longer-term average condition (Pachauri et al., 2013). The Climate change is mainly caused by various factors. This includes various factors, such as biotic processes, variation in solar radiation received by Earth, volcanic eruptions and plate tectonics. 1.2. History of Discovery The history of climate change initiates in the early 19th century, when the ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was efficiently determined. Later in 19th Century, various scientists argue that human emissions of the greenhouse gasses could change the climate. Most of the climate related theories involved the influence of forces from volcanism to the solar variation. By 1960, the effect of warming effect associated to Carbon Dioxide gas became increasingly convincing. However, some of the scientists also focused towards various human activities in the forms of atmospheric aerosols, such as pollutions, could have cooling effects on the environment (Doney et al., 2012). During 1990s, the effective computer models along with the confirmation of Milankovitch Theory of Ice Age focused towards the formation of weather changes in the environment. Since 1990s, the scientific researches based on the climatic changes included various disciplines, which has expanded and significantly increased the understanding of casual relation links with historic data and the ability to model the climate fluctuation numerically. Based on the recent works governed by the Assessment Reports of Intergovernmental Panel on Climate Change, it can be analyzed that climate change is a significant and long lasting change associated to statistical distribution of weather patterns over periods ranging from decades to millions of years. 2. Believer part of the Climate Change Paradox There are two paradoxes that seem to consistently arrive and thereby helps in believing the core factors associated to climate change. The first paradox includes simultaneously simplicity and complexity. Climate Change is generally considered as a complex problem which id diversely understood. It is a post normal science issue, and not at all a regular one. Climate Change seems to the individuals that believe in models squaring off against those for whom actual data is the only truth (Kirtman et al., 2013). Assuming the one that believes in basic science, one can still question about the factor of risks that assigns to possible scenarios of climate change while considering on how much risky they are comfortably taken. Even the groups that are demographically uniform universities tend to disagree on these questions. As a social issue, climate change is considered as an epistemic mess, rife with subjective issues such as climate justice and the various discourses of fear, risk, opportu nity, security, equity and sovereignty which compete for dominance in the sense making issues. Several scientists argued that climate change is mainly a cause of cognitive dissonance, which can be crippling. Confronting the evidences that most well meaning Westerners consumption habits contribute as much as to the problem as the most easily vilified of the oil companies (Seinfeld Pandis, 2013). As per the viewpoint of Tim Jackson, it can be discussed that The Myth of Decoupling drives power, fly and consumption rate already outstripped the factors that can be sustained by the planet, even as innovative technology rapidly increases efficiency. Moreover, Jackson further painted a picture regarding the efficient improvement of strategies that need to be avoided for the worst climate changing scenarios. Moreover, it has been observed that the common opinion associated to climate industry highlights towards the crowds of climate NGOs, consultants, developers, departments and the campaigners in order to ride the wave of climate madness and thereby sell the wind turbines, carbon accounting services and social licenses (Fankhauser, 2013). These movements are found to make easy assessment of the attacks and thereby form inaccurate claims related to the known impact of climate change and claiming fully that science is settled even though, in some crucial ways, its not. Based on a strategic viewpoint, it can be analyzed that addressing towards the conflicting worldviews, misappropriations, and debates of nationalism, localism or internationalism, along with political appropriations provides systematic design scales for various responses. Although most of the scientists agreed on the concept, however one can easily highlight towards its huge limitations and negativities. Thus, this first paradox associated to climate change legitimately means different from one individual to another. This is a complex term, but it is highly practical for most of the individuals (Qin et al., 2013). There is a cumulative, global, time bound, greenhouse gas budget and ongoing break on this associated paradox. 3. Non- Believer Part of the Climate Change Paradox The second paradox, which can be considered, is Scale, which is associated to the non-believers perspective. After the disappointment with the pace of change possible through the UNFCCC (United Nations Framework Convention on Climate Change) protocol, there led an evolvement of the debate about scale into a debate about goal setting. This was based on the concept of GHG-emissions reduction goals are politically engaging enough to be achieved. According to the concept of Mike Hulme, climate is considered as a change, which is related to the efforts and thereby should not be focused on the GHG reduction goals that put politically attractive objectives, such as the air quality or public health at the forefront (Hansen Sato, 2012). However, Michael Oppenheimer stated that people could get being efforts in order to transform energy system in their communities or the sectors they work in where they can visualize social and economic co-benefits of taking actions. 4. Adaptation and Migration Actions to Avoid the Ultimate Impacts of Climate Change The Climate Change Adaptation and Mitigation tend to consist of various actions that limit the magnitude of long-term climate change. This generally involves the reduction in human (anthropogenic) emissions of Greenhouse gases (GHGs). Adaptation to the adverse change of the climate is observed as an important element. Adapting towards an abrupt climate change often tend to minimize the effects associated to the consequence. However, when the adaptation capability decreases, then the consequences of climate changes prevails largely. Often this terms to have an immense effect on the environment. Thus, effective migration is considered as an important policy to avoid adaptation. Migrating to a more significant area, which has a moderate climate for life sustenance, is observed as an important factor. Mitigation involves in achieving the capacity of Carbon Sinks. This includes Reforestation policies to a huge extent. Moreover, the mitigation policies focus towards the substantial policies, which reduce the risk of human induced global warming (Bellard et al., 2012). Effective climate change mitigation would not be achieved if an agent acts independently in its own selfish interest. Most of the adaption actions tend to provide benefits of actions, which may accrue more directly to a region, individual or the associated countries that tend to undertake them for a short duration of period (Pachauri et al., 2013). Nevertheless, the financing of such adaptive activities remain an issue for the poor countries or its associated individuals. The common example of mitigation involved in the context of Climate Changes includes the switching to Low Carbon Energy sources such as the nuclear energy and renewable energy and thereby expanding forests and thereby sinks to remove the greater amount of Carbon Dioxide from atmosphere. One of the classical examples involves improvisation through insulation of the buildings. The other relevant approach associated to Climate Change is the Climate Engineering, which can protect the consequence to a huge scale. Most of the countries are associated to the parties of UNFCCC (United Nations Framework Convention on Climate Change). The objective of this organization is to stabilize the atmospheric considerations, which are associated to GHGs at the level that would prevent dangerous human interface associated to the Climate System. The Scientific analysis can efficiently provide information on the impacts of climate change, but deciding which impacts are dangerous requires valuable judgments. In the year of 2010, the parties associated to the UNFCCC (United Nations Framework Convention on Climate Change) agreed tat the future of the global warming should be limited to below 2.0 degree Celsius, which is relative to the pre industrial level. This might be revised to the target of limiting global warming to below 1.5 degree Celsius, which is relative to pre industrial levels. The current trajectory of the greenhouse gas emissions does not appear to be consistent with the limiting global warming to below 1.5 or 2 degree Celsius to the pre industrial levels. Based on these parameters, it can be completely analyzed that the other mitigation policies are also proposed, and are considered more stringent or modest. These newly created mitigation policies, which are proposed by the Western countries such as the United States of America and the United Kingdom tend to consider the limiting zone less than 2 degree Celsius. Thus, all these adaptations and mitigations taken by the counc il of United Nations Framework Convention on Climate Change can efficiently avoid the ultimate impact of climate changes to a huge scale.
