Human Systems And Climate Change Essay

“Scientists’ overwhelming conclusion is that climate change is happening and human activity is the primary culprit,” (“Climate Change”). The world we live in is falling apart more and more every day. Pollution; Global Warming; Climate Change; These are all problems that caused by people who have come forward in recent years, one of the biggest issues is climate change. The United States government needs to take aggressive steps to combat climate change because scientist have warned that if the climate changing progresses at its current rate, it could have disastrous consequences for life on Earth. Data shows that climate change is linked to rising sea levels, droughts, an increase in the risk of extinction of many species, and the increase in severe storms. With all the issues that are connected to climate change we are not doing enough to try to counteract the lasting effects it has on our environment.

Climate change is known as one of the greatest threats to the planet. It is not only a threat to the planet environmentally, but it is a threat socially and economically. As we all could feel, see, and know, the weather patterns globally and carbon dioxide in the atmosphere have been increasing over an extended period of time. Although it may seem like it’s not a dramatic change since it is data from over a large amount of time, it is considering the fact that the large amount of time is not that large as it should be. Climate change is nothing new to us. It’s happened many years ago in the past because a variety of reasons but as the years go on, the rate on charts are just getting higher. As much as I would like to blame this predicament on nature, humans has a fault as well. We release thousands of greenhouse gases into the air through many procedures, but there are things that we cannot entirely control. However, whoever’s fault it is to blame I believe that if we work together and think we will more likely be able to find effective solutions for this problem.

changing climate and how to respond to these changes. Their Fifth Assessment Report, which is

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

Climate change is the change in average weather of a region. Climate change can be, for example, change in region’s average annual rainfall or change in region’s average temperature for certain period (May, 2011). In a broader view, climate change can also be seen as change in Earth’s climate with an example being global warming.

Climate change is a rising issue of importance in our day and age, and one that is threatening our global society on many levels. It has become a wicked problem throughout the years. A wicked problem does not have a definitive definition due to large uncertainties. Atmospheric and oceanic concentrations of climate change have been consistently rising over time, and threaten to have immense human wellbeing, scientific and economic impacts in the future if the globe neglects to achieve reasonable emission levels. There is no one solution for a wicked problem.

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.

Climate change is a rising issue of importance in our day and age, and one that is threatening our global society on many levels. In the past few decades, scientists have discovered that our planet’s climate has been changing at an alarming rate. The way in which we have changed the land to

that human activity is likely to be the primary driver of climate change, the politics of global

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

It is widely held that climate change is real and happening now Case (2006) as global average temperature has warmed about 0.8°C within the past century. Coupled with this, the past three decades has witness a global average warming of 0.6°C (Hansen et al., 2006). This is largely to due to human induced factors (IPCC, 2001). A recent report produced by the U.S. National Academy of Sciences confirms that the last few decades of the 20th century were in fact the warmest in the past 400 years (National Research Council, 2006). The IPCC also projects that if greenhouse gas emissions, the leading cause of climate change, continue to rise, the mean global temperatures will increase 1.4 – 5.8°C by the end of the 21st century (IPCC, 2001). In a similar

The following is a summary of the IPCC Status Report on Climate Change. The following questions will be answered: is climate change occurring? About which aspects of climate change are we certain? Uncertain? What are the main factors determining climate change today? What is the likelihood that humans have caused these changes and what data supports this conclusion? And finally, what information is not yet available or are we unable to access at this time that may have bearing on the report and our understanding of climate change?

This global organization is called the Intergovernmental Panel on Climate Change. This world-wide collaboration of specialists were to compile scientific reports from across the globe and issue reports regarding the impacts of global climate change internationally and its impacts upon an array of ethnic groups. These reports include scientific and socio-economic data measuring both technical details as well as the effect local weather patterns have made on droughts, flooding, wild and domestic livestock, water supplies, and the all-important food production. The five reports the IPCC has issued to date show a strong correlation between greenhouse gases and global warming, and strongly state that climate change is causing severe changes in weather patterns with catastrophic result. The most recent report was released in March this year (Howard).

Earth’s history is filled with drastic climate changes, from ice ages to warm fertile periods. But only in recent years has the thought of humans having an impact on Earth’s climate been an issue. The definition of climate change is “the long term change in the statistical distribution of weather patterns over decades to millions of years,” but some recent definitions of climate change have been formed with the idea of human impact embedded in them. One such definition states “climate change as mainly the change in modern climate augmented by human activities.” Ideas of this arose in 1896 when Swedish scientist Svante Arrhenius carried out the first calculations of global warming. Arrhenius lived during the time of the industrial revolution, which introduced the use of coal, railroads and factories. He had ideas that the CO2 produced from burning fossil fuels might contribute to the increase in temperature of the Earth. Global warming is a global topic and the source of much controversy in the world today. Although some people may be skeptical of it, global warming is real, and there is evidence to prove it. On a basic level, we have noticed that the average global temperature has been rising over the past one hundred and thirty years, with the majority of this warming occurring since the 70’s and the warmest years within the past ten years.

Climate change is a major concern of the global community. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4) stated that global surface temperature have increased by about 0.74 ◦C between 1906 and 2005. Extreme high temperature events have become more frequent and more intense in recent years in some regions.
