King Salmon's Disappearance

Improved Essays
The fourth and final theory that I will be explaining deals with worldwide climate change. Global climate change is a hot button issue for many political and special interest groups and some scientists believe that it may be at the root of the King Salmon’s disappearance. Despite its relative sensitivity, when compared to other theories about the salmon crisis, it is accepted by almost all that it is a happening. Regardless of what side of the political aisle you fall on, it is simply factual that the climate is changing. The causes are typically the cause of the debate surrounding it, but I will leave that argument to those who are more knowledgeable about it than I am. The last fifty years or so have seen the climate warm up and it has …show more content…
In the Artic-Yukon-Kuskokwim Research Action Plan scientists write that “Changes to the marine environment experienced by AYK Chinook salmon upon entry to the marine environment and during the early period of the marine portion of their life cycle are certainly a plausible explanation for their decline in recent years” (Schindler et al.). Additionally, the prey of the salmon may be experiencing similar effects, and perhaps the climate change has caused significantly less habitable options for the crustaceans, amphipods, and smaller fish that make up the majority of the Chinook diet. A potential disappearance in prey may be the reason why the other salmon populations in the region remain strong, as Kings inhabit more northern environments in the ocean and eat prey on different organisms as a result. Furthermore, like the Northern Pike theory, the timeline also matches up with the disappearance of the Chinooks, with some small effects happening in the late twentieth century and increasing more and more into the twenty first. The main hole in the argument is the extreme complexity of the global currents and populations, which could have been affected. It is easy to see that the climate change could have caused the Chinook crisis, but it is very hard to …show more content…
The theories range from global climate change patterns to too many people dipping their setnets into the rivers. However, what we do know – conclusively – is that this problem is very real, and each day nothing is changed the problem persists, continuing to eat away at vibrant culture and economy. As biologists and researchers pry open the doors behind which the solution hides, the fishermen and small business owners of the several Alaskan communities that depend on this fish await with baited breath. Hoping to find that there is an answer, hoping that they will see the salmon return to color the Copper River red once more, hoping that all is not

    They hope to instruct and convince as many people as possible to fight for the future of the planet. From the technical point of view, this issue is of dangerous importance, and requires close inspection of historical patterns, alteration of current practices, and close observing of the atmospheric content in the upcoming. Many scientists assume that the general public is aware with the science about the atmosphere, and some people may disagree because they simply do not recognize how the influence of extreme CO2 excess could contribute to a alteration in global weather configurations. Others are alert of the situation, but are indisposed to make changes because their attention is in another…

    The problem with finding a solution to policy creation to combat the issue of global warming has been proven to be complicated and complex. Many ideas have been brought up within political spheres with regards to how best to go about this. Currently, the model of collective action is regarded as one of the more suitable ways to combat global warming. Collective action may help policy focused on global warming to an extent, however other ideas such as taking a polycentric approach to the issue will greatly aid in this challenge. Global warming policy development has been at a standstill around the world for a variety of reasons.…

    The video “The Most Terrifying Video you’ll Ever See” by Greg Craven is a video that discusses whether there should be significant action taken on climate change. Craven addresses one of the main problems with the climate change debate, which is that it has become a long bitter argument about whether climate change is real and if it is caused by human development. He is arguing that it doesn’t matter if climate change is real or not, significant action should be taken to further prevent or combat climate change because when faced with uncertainty about the future taking action is the only reasonable choice. I disagree with Craven because there should be a greater focus on information and facts when it comes to making a decision about climate…

    Finally, many countries, make reaching a comprehensive international climate change agreement difficult by taking on defensive attitudes rather than constructive ones regarding the degree of responsibility they have in global warming in comparison to other states. This, is a determining factor in how much they believe they should need to make changes and contribute to reducing their emissions. In her article: “Negotiating challenges and climate change”, Joyeeta Gupta uses negotiation theory to provide insight into the bargaining strategies used by states during climate talks which affect the agreement construction process. It serves as a useful way of understanding the outcome of strategies used by developed and developing countries. On one…

    They suspect that overfishing is the underlying issue of salmon stock decrease. Information regarding certain salmon species has uncovered that near extinctions of some salmon species are due to large commercial fishing vessels. In a 2012 study by DUJS, the giant Mekong Salmon Karp has seen a more than ninety percent decline its population due to overfishing DUJS (2012). This is very compelling research into this specific salmon population. However, global warming producing higher ocean acidification has inadvertently caused a greater decrease in the salmon population that overfishing.…

    Thompson explains, “it is difficult to assess the full effects of global warming, and harder still to predict future effects” (13). Regardless, everyone will be affected by climate, and not only humans will suffer but many species will go extinct due to the climate change. “Nonetheless, faced with the complexity of managing human-modified landscapes for biodiversity at multiple scales as global change proceeds, there is increasing interest in how natural landscapes have responded and will respond in the future to global change” (Baker 144). Eventually, people will learn that we can no long diminish global warming, and we will not be able reverse the negative effects. Climate change is a major world issue that will cause many problems worldwide.…

    Global warming is a real problem the population faces today. The debate between if climate change is a real problem or not could easily be put to an end if the general public had access to scholarly databases. The most commonly used excuse as to why global warming does not exist is the harsh winters certain areas of the United States receive. What many people do not know is that local weather and overall climate do not coincide with each other. In addition, environmental changes and actions needed to help slow the process down has become a political issue as well.…

    In an article by Joseph F.C. DiMento and Pamela Doughman called, “Introduction: Making Climate Change Understandable” the authors address concerns regarding climate change and what needs to be done in order to improve the problem that the world has in hand. They use various reasons and evidence while also acknowledging the counterpoints. DiMento and Doughman explain that in the public eye the topic of global climate change is one that is not only difficult to comprehend it is one that is often ignored (5). That is to say, the public is aware of the problems that are arising due to Global Climate, however, they either ignore completely or they do not understand the seriousness of the problem at hand.…
