Anthropogenic

1. Summary • This report is analysing a fictional blog post. • Evidence to support anthropogenic climate change will be discussed. • Defence mechanisms that the author possibly uses will be evaluated. • This report will explain why the author of the blog is making the claims by explaining the ideas surrounding conspiracy theories. 2. Introduction The author of the blog post begins by describing two items in the news which they describe as ‘worrying’. Firstly, the announcement of treble subsidies

impact on recent climate change. Climate change that is influenced by human activity is called anthropogenic climate change. Anthropogenic climate change is caused by the emission of greenhouse gases into the atmosphere. Greenhouse gases are heat retaining gases that over time collect in the atmosphere. Some of the most common greenhouse gases that are having a large effect on the rate of anthropogenic climate change are carbon dioxide, methane and nitrous oxide. When these gases are emitted they

Seagrasses are essential primary producers that provide habitat and refuge to fauna. Anthropogenic influences have caused global loss of seagrasses and a major contributor is eutrophication, which increases phytoplankton and algal populations, reduces light availability, and causes daily hypoxic conditions. Eutrophication is commonly linked to declines in temperate conditions and is more difficult to link to tropical systems since decreases are typically related to physical damage and diminishing

acid (H2CO3) which also leads to a decrease in carbonate ions. Learning more, it has been found that approximately 30% of the carbon dioxide that is released into the atmosphere is absorbed by the ocean and as more carbon dioxide is released by anthropogenic sources, such as burning of fossil fuels and industrial activities, the levels of carbon dioxide found absorbed within the ocean increases(NOAA, 2012). In the ocean, carbonate ions and calcium carbonate minerals are found to be the building blocks

change we can draw conclusions relating to the impact and influence that humanity is having on climate change. It is by first establishing naturally occurring climate changes legitimacy and causes and then linking these causes to our now current anthropogenic climate change This second section is also the more controversial, nobody disputes naturally occurring climate change, but as soon as causation is assigned to humanity and particular sections within; it becomes a vigorously debated topic. By first

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. Scientists have given numerous warnings that human-caused, or anthropogenic, climate change is not only occurring now, but accelerating more quickly than predicted (Maibach, Myers, and Leiserowitz 295). Global warming contributes to

natural and man-made causes, and leads to respiratory diseases and the depletion of the ozone layer. Air pollution is separated into natural and anthropogenic (human-made). Natural causes of air pollution includes forest fires and volcano eruptions as well as the breakdown of organic material by bacteria into the atmosphere. However, anthropogenic causes are of the most concern and are much discussed due to the

forcing factors for the development of HABs include climate change and droughts, nutrient enrichment, and other modifications resulting from anthropogenic activities such as contaminants from effluent and storm water discharges, natural resource extraction, agricultural runoff, and salinization” (Brooks et al., 2016, p. 8), which shows that both natural and anthropogenic factors play a role in HABs. Like Brooks’ work, Chapman’s work shows how HABs should be considered a contaminate. In the article “Harmful

The human population is increasing and so is the amount of food we consume; each year food consumption increases 0.5% per person and less than half of the global grain we produce, is directly consumed by humans, this is because the rest goes to feed farm animals. However, factory farms are using more than they can produce, considering the fact that animals are being fed 6 kg of plant protein and in return are only producing 1 kg of animal protein, this also means other people are getting less food

Discussion In the early 1990s, USGS scientists developed a method to date ground water using chlorofluorocarbon (CFC) content of the water that is able to be used on most shallow ground-water systems. During the past 50 years, anthropogenic activities have released chemical and isotopic substances to the atmosphere. These atmospheric substances, such as tritium (3H) in water vapor from detonation of nuclear bombs in the 1950s and early 1960s, and chlorofluorocarbons (CFCs) from refrigeration
