Transcript: Global Warming What is Global Warming? Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace. It's becoming clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than in the last 650,000 years. Global Warming also referes to the avarge the worlds heat increases. what causes it and how can it be Stopped? Claminate change and poplution are causes of global warming; Dealing with climate change takes everyone doing everything we can. We hve a long way to go with U.S. energy policy and must also work with India, China and the rest of the developing world to leapfrog the fossil fuel path and move directly into a clean and efficient energy model. What to do? Plant trees use less fossil fuels donate for reseach protect native forests and moree.... ELLIE EGAR GREENHOUSE EFFECT

Transcript: Global sea level has risen between 10 to 25 cm in the last 100 years and will rise faster still in the coming decades. Global Warming Global sea level has risen between 10 to 25 cm in the last 100 years and will rise faster still in the coming decades. Global warming will cause a continued and accelerated rise in sea levels, threatening half of the world's most critical coastal wetlands. A one-meter rise in sea level would threaten half of the world's coastal wetlands of international importance for their biodiversity. Global warming will expose millions of people to new health risks. Infectious diseases are emerging, resurging and undergoing redistribution on a global scale. Global warming will cause a continued and accelerated rise in sea levels, threatening half of the world's most critical coastal wetlands. At the rate our climate is changing, the world will soon be warmer than at any time in th last 10,000 years. About 30 new infectious diseases have emerged in the past 20 years.

Transcript: -Arctic ice is predicted to be completely gone by the year 2080. Argument: Arctic and Antarctic ice is not melting as quickly as claimed. Argument: Rising sea levels are slowing and are part of a natural process. -Polar bears are on the Endangered Species list and will likely become extinct by the end of the century. -Since 1970, arctic ice volume has sharply declined. Argument: The planet has naturally undergone many warming and cooling periods in the past. An Inconvenient Truth Warming Trend Arctic Ice -The average temperature of the earth has risen over one degree in the past century. -Deforestation and burning of fossil fuels increases the amount of carbon dioxide in the atmosphere at a much greater rate than would happen naturally. -By the year 2100, the sea level is estimated to rise three feet, partially due to melting glaciers.

Transcript: Global Warming By Dania Khan What is global warming Global warming is the change in climate, which is mainly caused by pollution that we, humans are causing!!!! Are humans causing it? What might happen? Global warming or the change in climate could mean famine, or water and food shortages and it might also have a huge effect on wildlife. Animals have already started getting extinct. Global Warming The Greenhouse Effect Pollution This graph shows the trend and how fast global warming is affecting our environment!!!!! Thank you for watching my presentation, i hope you liked it and learned something new!!!!! (cc) photo by Franco Folini on Flickr Global warming occurs when the mean temperature of the Earth’s surface starts to increase. Since the late 1800s, the average temperature that has increased is 0.7 to 1.4 degrees Fahrenheit. By the year 2100, scientists have estimated that the temperature could rise up to 2.5 to 10.4 degrees Fahrenheit. Experts are finding a way to identify and cure the causes. (cc) photo by Metro Centric on Flickr Even if we help stop the gases from spreading it would not right away stop global warming. Too much of methane, carbon dioxide, and other secondary gases are not good for the environment. We humans are pouring all that carbon dioxide into the air a lot faster than plants and oceans can absorb. Greenhouse gases are a problem because of the quick changes in the climate. Living things such as humans, and animals may not be able to adapt quite as fast. Change in the climate would also mean many difficulties for living things. Building industries, cutting down trees, and pollution have a great effect on the change of climate. These activities have highly increased the amount of water vapor, carbon dioxide, methane, and nitrous oxide, all of which help trap the heat near Earth’s surface. Based on more than 2500 scientists from more than 130 countries have said that humans caused most of or all of the changes happening in earth today. When humans cause change in the climate or global warming, it is usually called Anthropogenic climate change. (cc) photo by Metro Centric on Flickr Picture of Global Warming--Pollution!!!!!

Transcript: What is global warming: Global warming is when the Earth warms up( when the temperature rises). It happens when theses gases carbon dioxide, water vapor, nitrous oxide, and methane trap heat and light from the sun in the Earth's atmosphere, which increases the Earth's temperature. This can burn and kill plants, animals, and humans. What causes global warming: Many things cause global warming such as: cars watching a T.V. turning on a light How can science improve global warming: It's really not the scientist fault it's everybody's fault. One main reason is becasue we all use cars and everything that can cause global warming. There is one thing that scientist and car makers are trying to do. That is making hybrid cars they dont cause that much and its better with gas mileage and they help our atmosphere out. How i would try to stop global warming The way i would try to stop global warming is how the scientist are doing we can make hybrid everything that way our atmosphere wont be worse than what it already is.
