Does one ever think of the potential catastrophic harm they’re causing by turning on the lights or by using their cars? Don’t we want a world where our grandchildren and great grandchildren can live safety and comfortably? At the rate were going this will not be possible; we’ve added more than 1.4 trillion tones of Carbon Dioxide (CO2) in just two hundred years, and its messing up our planet (Siegel 1).

The use of fossil fuels has greatly increased the amount of atmospheric and oceanic CO2 to a point where it’s ruining the natural flow of the world; the earth’s temperature is rising. As a result, the polar ice caps are melting causing the seas to rise. With only a 1 meter increase in sea level the United States alone could lose over 10,000 square miles of land, and thousands of houses will be destroyed. The effects will be just as prominent around the world: many islands will become submerged, 17% of Bangladesh will be underwater, and tens of thousands of people will be displaced (“Global Warming” 3).

Not only will this be catastrophic for the humans, but animal and plant life will suffer too (“Global Warming” 4, 10, Than 1-4). The oceans will become more polluted and warmer which will cause fish along with coral reefs will die (“Global Warming” 4). The heat will bring animals to extinction; their migration patterns will be altered, change their diet, and force them to live in different locations in order to find a suitable climate (Than 1). Additionally, the warming will hurt the crop production. Crops have a very specific range of temperatures they should grow in order to maximize their yield, and if the earth is going to be above the temperature then crop yield will suffer. Projections for the year 2050 show...

...9). The proposal calls for ships that blow micro sized drops of seawater into the air, and use the Twomey effect to increase the reflectivity; the water uses the salt as a nucleus and when the small drops of water reach the cloud level, they will bond with the existing clouds, increasing the amount of water in the cloud, and therefore making it more reflective (I 2). The plan also calls for ships that run off the wind, and therefore don’t contribute to the CO2 production. Additionally, these ships could be used to target specific areas that need to be cooled sooner rather than later: above the ice caps, and by coral reefs. This proposal has the ability to “hold the earth’s temperature constant for many decades” (Schneider 9), through the ability to add more ships to meet our CO2 production, very natural, and relatively cheap: a proposed $1.5- 3 million per ship.

Moral Hazard Argument Agains Geoengineering Essays

- ... Geoengineering could have some technical Dependence Hazards as well. We could become dependent upon this geoengineering technology and may never do away with it because we will always need to keep on top of things. If we lose funding climate change could be quick and far worse than it might be if we were ever to allow it to progress. ( Hale, 2012, p 124) Geoengineering only treats the signs and does not fix the core of the problems. “you’re papering over the problem so people can keep incliting damage on the climate system without having to give up fossil fuels” ( Hale, 2012, p 125) An example of this band aid solution is placing a band aid on a patient suffering a heart attack....   [tags: countering climate change]

Essay about The History of Global Climate Change

- Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene, from approximately 110,000 to 10,000 years age (Clayton, 1997)....   [tags: Climate Change, Global Glaciers Recession]

Global Warming and Climate Change Essay

- Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”. Rather than worry too much about emissions, we should accept the world is going to get warmer anyway and adapt to global warming by building better flood defenses and developing drought resistant crops....   [tags: Climate Change Essays]

Global Climate Change: Society Can Slow it Down Essay

- The Earth is being poisoned. It is a well-known fact; however, a remedy has not yet been offered. Everyday, alarming amounts of toxins are released into the atmosphere, and more recently into the Gulf of Mexico. British Petroleum (BP)--one of the largest suppliers of oil in the world--has dispersed an insurmountable amount of oil into the gulf. As a result of this, marine and bird life in the area has been severely affected. Fishermen, whose livelihoods depend on the fishing season, are being told they cannot fish....   [tags: Climate Change, global warming]

Essay on An Analysis of Climate Change and the Possible Solutions

- Introduction Since the 1980s, climate change has transformed from a scientific discovery to being the most prevalent issue within the arena of political ecology. The world today has yet to fulfil the goal of emission reduction to a level that can keep global warming below the threshold of two degrees Celsius. Amidst various approaches used to cure the pressing climate change problems, the IPCC publication of Climate Change 2013: The Physical Science Basis Report suggested that the use of geoengineering technologies could be a possible solution (IPCC, 2013)....   [tags: geoengineering, ethics, environmental issues]

Climate Change: Global Emissions of Green House Gases Essay

- There are growing concerns about climate change and the effect of ‘greenhouse gases’ (GHG) on the gradual increase in world temperatures over time, now commonly known as global warming. The ‘greenhouse effect’ means that ‘greenhouse gases’ such as water vapour (H2O), carbon dioxide (CO2), methane, nitrous oxide, and fluorocarbons insulate the Earth by absorbing heat from the Earth’s surface and reflecting it back into the atmosphere, acting in a similar way to a thermal blanket (Houghton, 2005)....   [tags: Environment, Global Warming, Climate Change]
