Global Warming November 17th, 2006 Student Meteorologists: Brian Kerschner and Kristin Ketchell Let’s Start With The Atmosphere… What is the atmosphere? • A “bubble” of gases and water vapor surrounding the Earth from the surface out 15 miles! That’s 80,000 feet! • The atmosphere is made of gases like Carbon Dioxide, Nitrogen, Oxygen, etc. •There are other gases present in the atmosphere called Greenhouse Gases. Some examples are Carbon Dioxide, Methane, Ozone, Nitrous Oxide, and most importantly…water vapor. So…What Does The Atmosphere Have To Do With Global Warming? Gases in the atmosphere are responsible for what is known as the Greenhouse Effect. We Can Think Of The Greenhouse Effect Like This… The Greenhouse Effect The Natural Greenhouse Effect is when gases in our atmosphere trap heat from the Sun and keep the Earth warm. When operating naturally, the Greenhouse Effect keeps Earth's climate at a stable temperature and makes it possible for humans and animals to live. The Enhanced Greenhouse Effect is the rise in the temperature of the Earth because of certain Greenhouse Gases present in the atmosphere. Human activity, fossil fuel emissions, deforestation, and pollution all contribute to the enhanced greenhouse effect. Greenhouse Gases Greenhouse Gases act as a blanket around the Earth. They allow the energy from the Sun to enter the atmosphere and reach the Earth, but when the Earth releases some of that energy, Greenhouse Gases absorb it and prevent it from escaping, causing temperatures to rise. Greenhouse Gases Most people believe that Carbon Dioxide is the most dangerous and important Greenhouse Gas, when in fact, water vapor has a larger effect on Global Warming. Water vapor is always present in the atmosphere. It is naturally released into the atmosphere by Evaporation. Water vapor is responsible for regulating the temperature of the Earth, which is why it is so important. Present Effects of Global Warming… In the past 100 years: • The average temperature of the Earth has increased by 1◦ F • Some glaciers have begun to melt • Sea levels have risen 6 – 8 inches • Ecosystems have had to migrate to more comfortable climates to be able to survive. Future Effects of Global Warming Future Effects of Global Warming 1. By the year 2050, sea levels are expected to rise 1 foot. 2. By the year 2030, the average temperature of the Earth is expected to rise 3.6◦F 3. Melting of Polar Ice Caps and Glaciers 4. Increases in hurricanes and tropical storms 5. Severe droughts in parts of the world 6. Increased rainfall in other parts of the world 7. Loss of unique ecosystems 8. Loss of crops that cannot survive in hotter climates 9. Spread of diseases and bacteria – they love hot, wet climates 10. Increased forest and wildlife fires What Is Being Done About Global Warming? Kyoto Protocol: It was developed to prevent harmful effects of global warming in the future. Countries around the world signed the document and promised to reduce greenhouse gases. Over 150 countries around the world signed it, including Mexico, Canada, the United Kingdom, France, and Germany. Can you guess which major country did NOT sign the document? Answer: The United States! Can you believe it? What Is Being Done About Global Warming? In 1988, the Intergovernmental Panel on Climate Change (IPCC) was created. This panel looks over environmental, social, economic and scientific information on climate change. We receive much of our information on climate change from this panel. What Can You Do To Help? 1. Turn off the lights when you leave a room. 2. Turn off your computer or the TV when you’re not using it. 3. Take shorter showers. Heating water uses energy. 4. Walk or ride a bike short distances instead of asking for a ride in a car. 5. The 3R’s – REDUCE, REUSE, RECYCLE 6. Plant a tree 7. Become more educated about global warming issues 8. Tell someone else about the importance of understanding global warming 9. Write to your local Congressperson to find out what they are doing to help stop global warming 10.Become a meteorologist at Millersville University! Question #1 There is only one gas that causes the greenhouse effect. True or False Answer : False Question #2 Which is not a greenhouse gas? Water Vapor Hydrogen Methane Ozone Answer: Hydrogen Question #3 Without the greenhouse effect would the Earth be colder or warmer? Answer: Colder (Below 0○F) Question #4 The greenhouse effect and the hole in the ozone layer are the same thing? True or False Answer: False Question #5 How much has the Earth warmed over the past 100 years? 1○F 2○F 3○F Answer: 1○F Question #6 The greenhouse effect will cause… Sea levels to rise Sea levels to fall Sea levels to stay the same Answer: Sea levels to rise Question #7 What is not a future effect of global warming? Increased forest fires Loss of ecosystems More crops and farmland Melting ice caps Answer: More crops and farmland Question #8 How much has the sea level risen in the past 100 years? 2 – 4 inches 3 – 5 inches 6 – 8 inches Answer: 6 - 8 inches Question #9 Which country did NOT sign the Kyoto Protocol? United Kingdom United States Canada Mexico France Answer: United States Question #10 Name one thing you can do to help prevent global warming… Thank You For Listening! Does Anyone Have Any Questions?
