Global Warming and Hurricanes.
I argue that global warming causes a rise in water temperature, and thus affects the strength of hurricanes, which in turn is hurting both the economy and wildlife in the devastated area. As global temperatures go up, so does the SST, “sea surface temperatures”. When the SST goes up the strength and intensity of storms goes up, and when the intensity goes up Hurricanes damage the economy and wildlife.
In the past, Sea Surface Temperatures, “SST “have always been going up and down, either due to the seasons, or the co2 levels in the atmosphere. In the last 40 years however there has been an increase in SST, from 1970 to present we have undergone a 1-degree temperature change. A raise in SST affects everything from the bleaching to coral reefs, to larger storm, and this is due to human’s impact on the earth, and our CO2 inputs into the atmosphere.
Global warming is caused when CO2 or other green house gasses are put into the atmosphere through combustion. When the suns rays hit the earth, some of the rays bounce off while others hit the planet. The rays that do hit the planet bounce off the earth hit the atmosphere and bounce back, and escape, making the planet warm and inhabitable. If we didn’t have an atmosphere, it would be like the moon, very hot during the day, and freezing at night. The problems with these gasses are, they are not letting the ray’s escape as much. The rays are being trapped on earth for a longer period of time, and are overheating the earth. The main way green house gasses are produced is through combustion. Everything on earth contains carbon, and when something is burned that carbon is released into the atmosphere as carbon dioxide. Some of the main contributors to carbon dioxide are your cars, and your electricity, through the burning of coal, and petroleum.
As SST go up, so does the intensity of storms. We have graphs that prove all the way back to 1850 that, as SST go up so does the number of named storms. “A storm large enough to be named”

This is because of the way hurricanes are created. A Hurricane is caused when ocean temperatures reach 80 degrees, and the ocean water starts to evaporate rapidly. The higher the temperature the more water is going to be evaporated. The hot air rises while the colder air is condensed into clouds. As more and more water is sucked up, the clouds begin to spin, and create wind. That is why hurricanes are normally found over tropical oceans where the water temperature is warm enough for it to evaporate. While storm amounts are not growing all over the world, the North Atlantic shows a drastic increase in tropical storms and hurricanes. In the last 35 years the number of category 4 and 5 hurricanes have almost doubled along with an increase in wind speed and size.
1945-1955 1995-2005
#Named storms 115 165
# Hurricanes 74 112
# Category 4+5 19 28
Scientist predict that the number of level 4 and 5 hurricanes will double, corresponding to a 60 percent increase in damages along the coast line.
When a hurricane makes landfall it brings death and destruction along with it. With a hurricane come strong winds, storm surge, and flooding, all of which create damages to property. At a category one level a hurricane will do as little damage as damaging tree’s and shrubbery, but as storm levels increase so does the damage it carries with it. At a category five level, storms will create extensive damage to homes, blow away small buildings, and flood anything less than 15 feet from sea level. This involves extensive damages from flooding and from house close to the ocean. Already the average cost of hurricanes a year is estimated at 1-3 billion dollars in damages, just imagine what would happen to the economy if we had a category 4 or 5 every year. Hurricane Katrina, cost the United States 110 billion dollars, and Hurricane Andrew cost the U.S. 28 billion. If that amount were to double the economy would crumble.
Not only do larger hurricanes mean more damage to infrastructure, but it also takes away from jobs. After Hurricane Katrina unemployment went from 5.8 percent to 11. 5 percent, nearly 400,000 jobs were lost, and when so many people are job less, there is no money circulating.
Hurricanes both negatively effect humans, and sea life. When a hurricane comes through, especially a large one, they destroy coral reefs. Many coral reefs, such as ones inhabited with Elkhorn coral, were destroyed, the branches would snap off, hurting fish, and stirring up sediment. Hurricanes destroy biodiversity among coral, because it makes only the stronger coral survive. Hurricanes have, in some places, totally transformed the layout of the reef. They have created slower growing dome shaped corals that can withstand the constant pummeling of the waves. When the coral is destroyed, fish lose an area to feed and breed, and the biodiversity of fish in that area die off.
Even though hurricanes hurt coral reefs, they have positive roles as well. NASA, has proven that hurricanes help create plankton blooms, in what else would be a dessert of an ocean. When a hurricane goes over an area of water it sucks phytoplankton “plant plankton” from deeper waters to the surface of the water, creating a plankton boom. This once dormant plankton, or “Marine Snow” reacts with the sunlight and produces chlorophyll. “Chlorophyll is what makes phytoplankton photosensitize” The hurricane is creating an upwelling and is producing nutrients to help feed fish, and recycles old water, and reduces CO2 in the atmosphere.
From the research I have done 2120 does not seem like a very friendly place to live, especially on the east coast. With the amount of category 4 and 5 hurricanes predicted to double, and the economy the way it is, this is sounding like something out of the movies. Thankfully these are only predictions; there is no telling what is to happen in the future. The saying holds true though, it is better to be safe than sorry. If we don’t look towards a renewable future, CO2 levels will continue to rise along with SST, we are the future, and we have the power to change it.
One of the ways we can lower our CO2 emissions is through riding our bikes. As I said previously CO2 is caused through combustion, and cars being run on petroleum cause a lot of CO2. Just biking 4 miles saves 15 pounds of pollutants from being put into the atmosphere. Another way is to cut down on CO2 emissions, is to cut down on electricity. Coal burning power plants make up for roughly 52% of the U.S.’s electrical needs, and produce harmful chemicals such as CO2, sulfur oxides, and mercury. All in all it is up to us to make the changes necessary, to change the world.
