Global Perspective

For my final blog post of the term, I will focus on Global Perspective. A global perspective is a viewpoint that attempts to understand the place of individuals, groups, cultures, and societies in the world and how they relate to each other. An example of a global perspective is studying the implications of economic policies on illegal drug use specifically the supply chain, where the drug is produced, and the local area where the drug is sold.
The link below provides information on the global perspective of climate change. In terms of the math part of this, According to The Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change, the atmospheric concentration of CO2 has increased from 280 ppm in the period 1000–1750 AD to 379 ppm in the year 2005. The concentration of methane in the atmosphere has more than doubled from 700 ppb in the period 1000–1750 AD, to reach a concentration of 1774 ppb in the year 2005. The concentrations of hydrofluorocarbons, perfluorocarbons, SF6, and N2O have also increased. The tropospheric concentration of ozone has increased even though its stratospheric concentration has decreased.

Never Pay for Gas Again

One engine for carbon dioxide emissions into the atmosphere has to be the driving of cars to various locations. With millions of people needing to drive to work or other activities this leaves the atmosphere and our planet earth taking the hit. It is determined that every gallon of gasoline burned creates about 8,887 grams of carbon dioxide. Now think about how many cars are on the road and how many people go through gallons of gasoline everyday, week, month, and year. The typical car releases 4.6 metric tons of carbon dioxide per year and this is an extreme amount. If we can reduce the amount of vehicles on the road this problem can be solved. One way to solve this is to turn to electric vehicles. Many high end brands such as Tesla and Audi have developed electric cars but those certainly are not affordable for millions of people in America. Recently cheaper, more affordable car companies are producing electric cars such as Toyota and Nissan. If Americans can become aware of the environment and the emissions of Carbon Dioxide they could be interested in investing in an electric car. Not to mention the extremely expensive gas prices all throughout the U.S., whereas electric cars require no gas. For those that do not have interest in electric cars, there are several other options to protect this earth such as carpooling, trains, and biking. Not every single American will listen to these suggestions, but little at a time I hope America can transform into an electric car dominated country.

Carbon dioxide’s impact on climate change

Carbon dioxide is a greenhouse gas that contributes greatly to the Earth’s temperature to rise, therefore heavily impacting climate change. Carbon dioxide is also known to react with water molecules which fluctuates the ocean’s pH level. The drop in pHI in the oceans, known as ocean acidification, has lowered from 8.21 to 8.10 since the Industrial Revolution. This is a significant change because a change of o:1 in pH indicates a 30% increase in acidity of the oceans. Another impact carbon dioxide has on the climate is through atmospheric carbon levels. Atmospheric carbon dioxide levels were estimated to be 412.5 parts per million in 2020. The global atmospheric carbon dioxide level has increased by 12% over the past 20 years. The present day levels of carbon dioxide are higher than they have been in 3 million years when conditions were hugely different in terms of the sea level and the regular temperature of the globe. The reason that the atmospheric carbon dioxide levels are so high today is due to the burning of fossil fuels that are returning carbon to the atmosphere at a higher rate that makes it increasingly difficult for the atmosphere to remove all of the carbon through its natural processes alone. This amount of carbon dioxide warms the Earth and contributes to other greater factors that are putting the Earth at risk. Atmospheric carbon dioxide may exceed goo parts per million by the end of this century if global energy demands continue at the rate they are going at or even increase.
