Global Warming Thesis Statement

Climate change is quickly affecting many social and economic sectors, both directly and indirectly. This is particularly true within the natural habitat sector, as varying impacts on global biodiversity threaten the existence of many species world-wide. While many problems such as warmer temperatures and rising sea levels are attributed to increasing carbon dioxide (CO2), there is one crucial problem that is often overlooked: Ocean acidification. As pH levels in the ocean fluctuate, there are devastating effects on sensitive marine ecosystems and individual species. Increased acidic conditions can pose threats to habitats, such as coral reefs and sea grasses (Guinotte and Fabry 320). These living habitats rely on calcium carbonate to form strong external structures, yet higher pH levels inhibit the organisms’ ability to successfully absorb the compounds needed for this process. Additionally, higher levels of ocean acidification can induce decreases in skeletal-forming compounds, diminishing entire populations of small ocean organisms such as crustaceans and phytoplankton (Doney). Therefore, it can be deduced that the increase of greenhouse gases in the atmosphere cripple the marine wildlife ecosystems, because the addition of greenhouse gases, caused primarily by anthropogenic conditions, are acidifying the ocean and disrupting the bio-chemical compounds that are necessary for many marine species to survive.

NGS integrates greenhouse into other major policy initiatives, such as the Natural Heritage Trust, and launches new measures to increase greenhouse emission reduction activities across the Australian community. It provides the strategic framework for an effective greenhouse response and for meeting current and future international commitments. It will provide a fresh impetus for action by governments, stakeholder groups and the broader community and set directions for that action into the next century.

Serge M. Garcia and Andrew A. Rosenberg expect that global warming will affect the “availability, stability, access and utilization of food supplies” (2010). This will have important consequences for an already constricted system. Rising water levels will affect the habitat of ocean and land dwellers. The availability of fish will be altered as species acclimated towards warmer water migrate towards the poles, due to increasing water temperature (Garcia and Rosenberg, 2010). Ocean acidification is the foremost critical effect of global warming on the oceans. It results from the absorption of atmospheric carbon dioxide by the oceans, which lowers the pH of the water. The National Oceanic and Atmospheric Administration (NOAA) of the US states that there has been about a 30% increase in ocean acidity since the beginning of the industrial revolution. Moreover, current CO2 output levels would lead to a 150% increase in ocean acidity by the end of this century (NOAA). Increased ocean acidity will have drastic effects on shellfish and coral, due to their calcium based nature (NOAA). Reduced quantities of shellfish and coral will further alter presently dwindling habitats and amplify the loss of biodiversity. Garcia and Rosenberg explain that temperature changes will greatly affect fish’s metabolism, growth, and reproduction because they are cold-blooded. This will further influence the availability of food and the

Massive crop failures can already be felt around the world. According to recent research, there is a 90% chance that if we continue the path we are on, 3 billion people around the world will be forced to move to milder climates in order to survive. This is predicted to happen within the next 100 years. Another problem we face, is widespread extinction of species. " According to research published by nature, 2001, by 2050, rising temperatures could lead to the extinction of more than 1 million species, And because we can’t exist without a diverse population of species on Earth, this is scary news for humans.

Since 1880, Earth’s global temperature has increased 1.4℉. A nearly one and a half degree shift in temperature may not seem very detrimental, but it has contributed to several main impacts on marine environments. These impacts include coral bleaching, altered behaviors, rising sea levels, and increased ocean acidity. The ocean

Change in the weather is not a disputable matter; however, the change in the weather pattern is a concerning issue that might indicate an alarm of future harmful effects. Frequently, irregular weather conditions happen in a way never witnessed before, for instance, falling snow in the deserted areas that usually recognize with the hot and dry weather. In addition, noticeable incidents of heat waves that hit cold regions like Europe and north of the United States. According to the Climate Communication Organization, the high record’s temperature increased from 52 percent in 1952 to 90 percent in 2012, also the duration of the heat waves become

Thesis Statement: Global warming is a growing concern of scientists and researchers who believe that it is a serious problem for our planet. The concerns and research have also been questioned and have even been called myths. Millions of people find themselves affected by these weather pattern changes and are concerned for their futures. Activists on both sides of the argument are very passionate and not afraid to attack each other in every way they can. There are many questions that are still not answered, however, we continue to see drastic weather changes to Earth. We must go beyond the arguments and learn as much as we can to stop what could possibly lead to the destruction of our planet, our way of life and our future.

The ocean’s pH has a direct negative correlation to the amount of carbon dioxide in the atmosphere. As the carbon dioxide increases in the atmosphere, the ocean’s pH drops. The average pH shift is 0.1 in the past 200 years (Cooley et al., 2015). That number may seem insignificant, however, on a scale of 1 to 14, it is much more influential to the environment. Predictions from the National Oceanic and Atmospheric Administration (NOAA, 2017) show a more negative impact with an decrease of up to 30% in pH and increase in ocean’s acidity in the upcoming century. This increase in acidity has destructive impacts on the coral reefs themselves and the biological impacts on species of shellfish and pteropods. Just as humans need calcium to maintain a strong skeleton, organisms such as coral, pteropods, and various species of shellfish including mollusks, starfish and sea urchins need calcium carbonate to preserve a strong shell used for shelter and protection. The calcium carbonate deteriorates with an increase in acidity. It makes the shells and skeletons brittle and compromises fertilization and settlement of new coral and pteropods as well.

Former United States Vice President Al Gore became interested in global warming during his years at Harvard University studying under Professor Roger Revelle. During the Clinton Administration Al Gore pushed and encouraged energy efficiency and alternate fuel resources. After Al Gore’s presidential election defeat to Georgia W. Bush in 2000, Gore focused his full attention back on global warming. Al Gore Traveled across the United States and around the world presenting a slide show featuring the concerns of global warming. Using updated material and animation “An Inconvenient Truth” was created. In this film that was the fifth highest grossing documentary to date in the United States; Al Gore puts forth an argument about our climate.

Global climate has been changing and still continue to change. Over a long period of time, climatic fluctuations may be such that, a shift in type of climate prevailing over a given area, takes place. In that case, we talk of a

Climate change poses a problem whose consequences are global. In 2006, above average temperatures were recorded throughout the world for the 30th consecutive year. Increasing average temperatures are melting glaciers and polar ice caps, which raises sea levels and increases the risk of flooding in coastal areas. There is mounting evidence to the effect that these changes are not the result of natural climate variability. The thesis of climate change caused by humans is supported by many leading scientific bodies, including the British Royal Society.

In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of

Despite the widely agreed upon consensus of climate change and human causation in the scientific community, the general public is still out to lunch on the subject, influenced by politics and societal ideals. The most important thing about climate change is the effects it directly has on our planet and its direct effect on species. Demonstrating a specific occurrence of the direct effects of climate change is Coral reefs. Impacted by warming and ocean acidification, Coral is facing great distress and the future of coral reefs is ugly, scientists unsure but doubtful that they will be able to keep up with the rapid change. The important thing to see from climate change and the point that needs to be understood by the public is that the evidence and the effects on species all over the world are real, and earth and its systems and creatures account for one hundred percent of our resources, directly or indirectly. The health of our planet is our responsibility, and this report examines the ramifications of human life and a closer look at Coral reefs, a key ecosystem facing the heat.

Global warming is defined as the process of gradual growth of average annual temperature of the atmosphere, the Earth, and the oceans. Global warming and climate change threaten the very existence of earths inhabitants. In 2006, former senator Al Gore created an amazing award winning documentary on global warming named “An Inconvenient Truth”. Yet there are still skeptics that can 't decide on whether global warming is actually facts or a theory. People need to wake up and realize that this is real, just look around you. The Glaciers are melting, crazy weather patterns are happening, winters are getting shorter and summers are getting hotter. At the rate we are going we are destroying our Earth. Global warming is a man-made disaster that should be recognized all over the globe. This is an ethical crisis that deserves immediate action.

Imagine you are placed into the future. The year is 2100. You begin to live in this
