Climate Change and Business as Usual
Scientists have shown that over the past 150 years, since the start of the Industrial Revolution, human activities have been a substantial contributing factor to climate change. Emissions from carbon dioxide (CO2) and other heat-trapping gases, also referred to as greenhouse gases, have increased the greenhouse effect that causes the atmosphere to retain heat. This in turn has caused the earth’s surface temperature to rise. This is known as climate change, and the primary human activity causing it is the burning of fossil fuels. Although CO2 is absorbed and emitted naturally through animal and plant respiration, volcanic eruptions, and ocean-atmosphere exchange, atmospheric CO2 emissions have increased nearly 40% from pre-industrial times. The increase is largely due to human activities that include the burning of fossil fuels and changes in land use that require deforestation (EPA).
The effects of global climate change on the environment are very real and already observable. In the past, some of the things scientists had predicted that global climate change would cause were loss of sea ice, accelerated sea level rise and longer, more intense heat waves. We are witnessing those changes now. According to the Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, we can expect to see a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century. The impact of these temperature rises will be beneficial in some regions and harmful in others, with the extent of climate change effects on individual regions varying over time. The IPCC predicts that net annual costs will increase over time as glo...

Climate change is a global problem because this Earth is home to many, and the artificial sources causing climate changes have been caused by many people over the course of many years. The changes can be seen on a day-to-day level through the rise in average surface temperatures (Figure 3A, Figure 3B). Climate change will change landscapes and increase sea levels due to the melting of ice and changes in water runoff; put wildlife at risk of extinction; increase the risk of drought, wildfires, and floods; lead to increased likelihood of storm damage due to stronger storms and storms occurring in previously not at risk regions; and cause a development in more heat related illness (“Climate Change: Threats and Impacts”). The repercussions of climate change will affect every nation, and major changes will have to be made for everything from farming to fashion. With every way of life at risk and every person and nation making contributions, whether extreme or minute, climate change is undoubtedly a global
Climate change is on the international policy agenda primarily because of warnings from scientists. Their forecasts of a potentially dangerous increase in the average global temperature, fortuitously assisted by unusual weather events, have prompted governments to enter into perhaps the most complicated and most significant set of negotiations ever attempted. Key questions - the rapidity of global climate change, its effects on the natural systems on which humans depend, and the options available to lessen or adapt to such change - have energized the scientific and related communities in analyses that are deeply dependent on scientific evidence and research.
According to the United States Environmental Protection Agency (EPA), carbon dioxide is the primary gas emitted through human activities and is the most important human contributed greenhouse gas (Overview of greenhouse, 2014). Carbon dioxide is naturally occurring in Earth’s atmosphere. The passing of carbon dioxide through the atmosphere, oceans, soil, plants, and animals is what is known as the carbon cycle. This carbon cycle is important to sustaining life here on Earth. Carbon dioxide is important to life on earth because it is the main component of many biological compounds, minerals, and exists in various forms in the atmosphere (Carbon Cycle, 2014). Humans are disrupting this carbon cycle however by adding more carbon dioxide to the atmosphere and by removing natural absorbers of carbon dioxide, like forests to remove the carbon dioxide from the atmosphere. This is where the greenhouse effect comes into play, since the industrial revolution there has been an increase in the human-related emission of carbon dioxide mainly due to the burning or combustion of fossil fuels for energy. Other contributors include certain industrial processes, the differen...
Global warming is a problem that is often overlooked by many and is hindered among other problems that require immediate actions. Over the last 136 years the temperature in earth has increased 1.7°¬¬¬F. Although an increase of 1.7°¬¬¬F over 136 years may not seem like a lot but humans are destroying the earth at a faster rate than ever before. Human omissions are roughly equal to 4 Hiroshima atomic bombs exploding across the planet every second leaving future generations of human in jeopardy. With warmer climate comes with catastrophic outcomes like drought, which can destabilize the food sources on earth leaving millions of people hungry. Widespread extinction of most species on earth and the melting of polar ice caps can raise the sea level leaving most of the world’s coastal cities under water. This cannot happen overnight but if humans keep omitting at the current rate the outcome of climate change will become prominent
Mankind’s industrialization of the world has caused a drastic increase in temperature. This rise in temperature is caused by solar radiation remaining in our atmosphere because of gases produced by humans through the burning of fossil fuels, land clearing, agriculture, and other human activities. These gases block the radiation from escaping into space therefore warming our planet. The result is raising of ocean levels, extinction of species and threatening of children’s health because of disease and less freshwater to drink. While many view climate change to be a more natural occurrence than others do, scientists have proven the average temperature rise of the Earth between 0.4 and 0.8 °C over the last 100 years.
Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
Scientists and environmentalists started talking about global warming and the dangers of climate change long time ago but it is now when the consequences of these effects began to manifest themselves in a clearer and even worrisome manner. The temperatures on Earth are rising, the sea level is rising, the amounts of CO2 and ozone in the atmosphere are increasing, the amount and timing of precipitation is changing. All of these issues show tendency to worsen in the future, though it is hard to predict exactly by how much or at what rate they will unfold. One thing is clear – climate change has an impact on almost every area of our life and it deserves our attention and timely response.
The looming dangers of climate change have garnered considerable attention from the scientific community in recent years. Researchers from extremely diverse backgrounds have begun to look at the causes and potential effects of climate change from biological, economic, and countless other perspectives. The climate change debate has shifted considerably in recent years, as well. While disagreement about the existence of climate change was much more common several decades ago, most established contemporary scientists agree on its existence today (“Fifth Assessment Report Technical Summary”, 2014). Furthermore, the notion that climate change is nonexistent is widely considered an outright denial of reality, as the current dialogue in the science world dwells on the severity of the consequences. The scientific community has also reached a consensus that present human activity is unsustainable, though the timeframe of the most dire, irreversible effects varies.
One of the most important issues lying in our world today and in the future is climate change. Whether you’re a denier or an acceptor, several scientific studies have found that a storm is coming for us in the future, so to speak. We often ask ourselves, what are these effects we hear of? This leads us to the purpose of this paper, to show that climate change will have drastic effects across the globe. As time progresses, these effects that are constantly spoken of on national news as well as through documentaries have grown to become reality.
For many years climate change has become a crucial issue around the globe. The environment has considerably deteriorated by the change of climate: seasons are shifting, the earth 's climate is changing, sea levels are rising and ice is melting. Global warming and the greenhouse effect is a topic that is becoming more and more concerning and a lot of research is done in order to examine what the issues are and how these affect the economy (Stern, 2006; CCRA, 2012) but also business industry and politics (Hanley & Owen, 2004). This phenomenon is a result of approximately 100 years of carbon-dioxide emission (amongst other greenhouse gases) in the atmosphere (Stern, 2006). It is a serious phenomenon affecting the environment and living organisms.
Climate change is an extremely important issue that must be dealt with now. The damage that results from climate change is very significant. To date, 300,000 deaths have occurred, and another 300 million have suffered from the effects of climate change. However, the current statistics of damage done to humans is minuet, in comparison to the damage that will occur if we continue on with the current system. Scientific research indicates that the average world temperature will rise by 1.4c to 5.8c. To an average person the increase of one degree of average temperature is deceivingly low. Nonetheless, just one degree
The most destructive human contribution to climate change is fossil fuels combustion, which results in the release of carbon dioxide and other greenhouse gases into the atmosphere. Increased carbon dioxide, methane, nitrous oxide and halocarbons levels in the atmosphere cause an imbalance in the earth’s energy. This is because the gases alter solar radiation and thermal radiation which regulate the earth’s energy. Research indicates that anthropogenic climate change is the cause of the increased global warming over the last fifty years. 57 % of the carbon dioxide emitted is absorbed into the atmosphere while the rest is absorbed into the oceans. Carbon dioxide in the atmosphere is the most central greenhouse gas that is associated with global warming (Eby, Zickfield, Montenegro, Archer, Meissner, & Weaver,

Climate change is an inevitable phenomenon that is being experienced globally in various forms such as temperature rise. Sea level rise, droughts, floods, hurricanes, landslides, etc. According to the forth assessment report of the IPCC project even with immediate implementation of mitigation strategies global climate change will continue for decades. Climate change is inflicting serious consequences on human wellbeing and will continue to inflict damages in the future. It is estimated that mean global temperature will rise by 1.8 ºC - 4.0 ºC by end of the 21st century (Izaurraade, 2009). A new global climate model predicts that in the coming decade the surface air temperature is likely to exceed existing records (Smith et al., 2007). Growing season temperatures in the tropics and subtropics by end of the 21st century will exceed the most extreme temperature recorded in the history (Battistic and Rosamond, 2009).
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors.
