Ipcc Status Report on Climate Change Summary Essay

The report of the United Nations Intergovernmental Panel on Climate Change (IPCC), consisting of more than 150 scientists, states that (Stocker, 2013) “Warming in the climate system is unequivocal and since 1950 many changes have been observed throughout the climate systems that are unprecedented over decades to millennia.” In the last quarter of twentieth century, the climate change problem has been the global issue. From the

The rising carbon dioxide (CO2) from the burning of fossil fuels and other human activities continues to affect our atmosphere, resulting in global warming and climate change. This carbon dioxide is also altering the chemistry of the oceans, causing them to become more acidic. From scientists and marine resource managers, to policy and decision-makers, there is growing concern that the process called ocean acidification could have drastic consequences on marine ecosystems. Such as altering species composition, disrupting marine food webs and ecosystems and harming fishing, tourism and other human activities connected to the sea.

Climate change is evident throughout the world and is a major issue. It is no secret that our planet is getting warmer. Global warming is now recognized in the scientific community as a real problem. There are multiple aspects that are causing this issue. Majority of the warming is caused by greenhouse gases. Volcanic eruptions and changes in the intensity of solar radiation have offset the warming partially. It is estimated that average annual temperatures will increase 3.5°F-9.5°F by the century’s end.

Climate change is happening – the extensive and critically accepted reports of the Intergovernmental Panel on Climate Change (IPCC) have removed any remaining doubt.

The first argument examined on the man-made global warning side is that increasing greenhouse gases caused by human activities is causing directly observed climate changes. The first resulting climate change discussed is warming global surface temperature. There has been an increase in global surface temperature of 0.74 degrees C since the late 19th century. In the last 50 years alone the temperature has increased by 0.13 degrees C per decade. North America and Eurasia have seen the largest increase in warmth. However, some areas of the earth have actually cooled some this past century (Easterling & Karl, 2011, para6). After the mid 20th century 70% of the global land mass saw reduced diurnal temperatures. From 1979 to 2005 the maximum and minimum temperatures have shown no change; both indicate warming (Easterling & Karl, 2011, para10). Furthermore, borehole temperatures, snow cover, and glacier recession data all seem to agree with recent warming (Easterling & Karl, 2011, para11).

Climate change is a threat that has been in existences for years, but appears to be a greater threat to the world currently. According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, there is more than 90 percent certainty that emissions of heat-trapping gases from human activities have caused “most of the observed increase in globally averaged temperatures since the mid-20th century” (IPCC, 2007).

The meaning and understanding of climate change has been a critical issue of concern to development, scientific and environmental researchers in the world. All over the world, there have been a lot of issues surrounding the causes and impacts of the phenomenon which led to the establishment of Intergovernmental Panel on Climate Change (IPCC) to help assess and provide information about climate change to society (Agrawala, 1998). This essay presents arguments on who is qualified to be an Intergovernmental Panel on Climate Change (IPCC) expert and who should be qualified. It begins by describing the role of IPCC and its structure including the roles of the authors of the IPCC reports such as lead authors, coordinating lead authors, contributing authors, expert reviewers, review editors and government focal points (IPCC, 2008). It then concludes by arguing in favour of the need for the inclusion of other experts as part of the Intergovernmental Panel on Climate Change.

It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).

Over the past couple of years, no other issue has received more attention in the marine community than ocean acidification. Marine biologists have been constantly working towards solving this issue and are hoping to see improvement’s very soon. Ocean acidification refers to the relentless growth in acidity of the Earth’s oceans. This on-going acidity has attributed to an important element; a constant rise of carbon dioxide levels in the Earth. The number one reason this issue is still happening is because of burning fossil fuels. In addition to burning fossil fuels, it has come to a point where it has enlarged a large amount of carbon dioxide by releasing it into the atmosphere. Chemists have taken this issue into attention that carbon enters the ocean and combines with seawater to fallout acid, which boosts the level of acidity. This process is known as ocean acidification.

Climate change looms large over our rapidly growing and continually changing world. No longer are the adverse effects of this menacing global issue a mere ominous projections, they are starting to become a very concrete reality. Countries are today experiencing rising sea levels, which compromises coastal infrastructure, prolonged drought, squeezing food supply and agricultural productivity, as well as extreme storms. Rising temperatures have already led to vast reductions in the size of the Arctic. There is now no doubt amongst scientists that anthropogenic activity has been the primary catalyst to the

Climate change is a global issue that is under an endless debate for its causes. The increase in the global mean annual surface air temperature in the previous century by 0.75C (IPCC 2007) in coincidence with the excess of the carbon dioxide (CO2) concentrations in the atmosphere from 289 to 353 ppm (Lean et al. 1995) by burning fossil fuels support the human-induced hypothesis of climate change. On the other hand, the protestors of the natural origin of climate change build their argument on the variations of solar radiation and volcanic activities (Rind and Overpeck 1993). Meehl et al. (2005) report that the global warming will continue in this century, even if the greenhouse gasses are stabilized. This reveals that the climate change is

Climate change has been discussed since the end of the 19th century, but scientists did not begin to take notice until studies began linking smog and pollution to dangerous increases in carbon dioxide which together have a “greenhouse effect” on the climate of the earth. Measurement of ocean temperatures supported these studies and created more concern for man-made disruption of the

A burden which lays on the shoulders of today’s man is that of climate change, namely, global warming. However, this evil has many ignored byproducts, some which are equally detrimental. In this thesis, we will write about the effects of one of the greatest of this, ocean acidification, known as “global warming’s equally evil twin”.

According to the National Aeronautics and Space Administration, the global temperature has risen about two degrees Fahrenheit since the late nineteenth century (“Climate”). Scientists define climate change as the escalation of the earth’s average temperature by natural causes or human inducement. As gases in the earth’s atmosphere increase, earth’s temperature follows coherently. Scientists cite a correlation between the earth’s increasing temperature and gases such as carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons in the atmosphere. Scientists have found that through human activity these gases show an increase. The upsurge of gases has a lasting effect on the environment: “Scientists warn of the loss of ecosystems and

Part of the conclusion of the article “Climate change: evidence of human causes and arguments for emissions reduction”, written by Baum, Misra, and Karmosky states, “Climate change is a complex and important issue. The study of climate change spans many academic disciplines across the natural and social sciences, humanities, and engineering. Existing research finds that there is very strong evidence that the climate is changing, that these changes are driven primarily by human activity, and that the changes will have very large impact on natural and social systems.” (12)
