Opening Statement

Hello, my name is David Su and this is my partner Vincent Liu. Today, we are here to talk about why Global warming is real and that you should believe in it. So far, many scientists proved that global warming is real with the constant rise of temperature from year to year. We believe that this is caused by human activities from factories, mining, drilling, etc... Every year, there is a 75% increase in carbon dioxide due to the burning of fossil fuels. According to National Geographic, the earth has warmed up 1.4 degrees Fahrenheit (.8 degrees Celsius). Most importantly, much of the ice in the north pole and south pole has been disappearing. Slowly mile by mile, the ice caps are disintegrating; glaciers are also impacted. So far, we lost over 890 cubic miles of ice in glaciers. Coral reefs are also dying of bleaching due to their sensitivity to the water temperature. Also, with the rise of temperature, there was a major increase in heat waves, severe storms such as hurricanes and tornadoes, and wildfires. These are all caused by the temperature rise. Droughts and floods also heavily increase every year. In Africa, the Sahara Desert is growing rapidly, expanding within every day due to the heat that kills many plants. Nearly all of Africa’s lakes evaporated into air. People are living without water there. As a result, many of the people there die of thirst. It is so devastating. According to the environmental defense fund, there was a record breaking amount of wildfires in 2006 where it burned nearly 10 million acres and had over 96,000 fires in Western America. One of the biggest reason why global warming is becoming reality is because of all the carbon dioxide. During the mid 1700s, human technology began to improve as time passes due to the industrial revolution. We, humans created new technologies that releases tons of carbon dioxide into the air every day; some of these technologies are factories, trains, cars, etc... More and more heat-trapping gases in our atmosphere are slowly disappearing and temperature is getting warmer. This goes back to what I said in the beginning, carbon dioxide are increasing and even if it is ‘natural occurrence’ you can’t hide the fact that human activities does cause carbon dioxide to go into the air. Therefore, Human activities does cause this strange phenomenon to happen and it impacts our world a lot.
