Global WarmingBy Abigail and Hosanna
What is the greenhouse effect? Climate change? Global warming?The greenhouse effect is the trapping of the
sun’s warmth in a planet’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface.
Climate change is a change in the world’s climate.
Global warming the gradual increase in the temperature of the Earth’s atmosphere, believed to be due to the greenhouse effect caused by increasing levels of pollutants like carbon dioxide.
How are each related?For example, when humans use cars,
airplanes, factories, etc. they release pollutants into the atmosphere, where they are trapped by the greenhouse effect, which contributes to global warming, which is increasing the world’s climate change.
What are the primary causes of global warming?Burning fossil fuels like coal, oil, and natural
gas releases carbon dioxide, and about half of that stays in the atmosphere (this is the biggest factor for global warming).
• (A single gallon of gasoline, when burned, releases 19 pounds of carbon dioxide into the atmosphere)
What are the possible consequences if we do not work to stop global warming?Mass extinction in the oceans (acidity levels
rise)Redraw the planet’s coastlinesRavage food supplies
How is global warming impacting economy?Newly created land and recently melted
water could be worth millions of dollars, causing fights to be broken out over them.
There would also claims on the undiscovered oil and other natural resources hidden in the Arctic ice.
What are several ways we can all fight global warming?RecycleUse less heat and air conditioningChange regular light bulbs to fluorescent
light bulbsDrive your car less; try walking or riding a
bikePlant trees
All of these help to reducing the levels of carbon dioxide in the atmosphere.
What is the basic argument(s) against global warming?Some scientists believe that there is no evidence in
humans contributing to the Earth warming upTemperature data shows no warmingPredictions about global warming aren’t based on
historical dataReports from the Intergovernmental Panel on
Climate Change do not prove that humans cause global warming
A warmer climate would be beneficial to civilizationEfforts to reduce greenhouse gas emissions
wouldn’t be any help and be too costly
What are your personal opinions about global warming?Global warming does exist, due to evidence
like the polar ice caps melting. It’s a much more serious issue than most
people think it is, since it could seriously affect future civilizations and ecosystems.
Humans can’t ignore this and think up excuses for why it’s not real. It’s not going to go away by itself.
