Slide 1: Global Warming By: Ashley Grimes Slide 2: Background Info. Global Warming is an increase in global average surface temperature due to natural or anthropogenic climate change.
The global surface area increase 1.33 degrees Fahrenheit during the 20th century.
The last 30 years has seen the highest surface temperatures recorded in history.
Glaciers are melting rapidly
Ocean temperatures have increased.
Sea levels have risen almost one foot.
The production and absorption of carbon dioxide and other greenhouse gases in not in balance. Slide 3: Causes of Global Warming The release of methane gas from arctic tundra and wetlands Slide 4: Pollution is one of the biggest man made problems that leads to global warming.
Burning fossil fuels
Green house gas CO2
Mining coal and oil Slide 5: Population
More food, more methane, more burning of fossil fuels
Transportation Slide 6: Effects of Global Warming Rise in sea level
Increase of ocean temperature
Decrease of snow cover Slide 7: Impact on Animals Birds laying eggs earlier
Plants are flowering earlier
Mammals are getting out of hibernation sooner Slide 8: Melting of ice in Greenland and Antarctica
Increase in agriculture
Water reservoirs drying up
In humans, heat-related illnesses and increased breathing problems
Chance of Malaria
Extreme weather Slide 9: Personal Contribution to Global Warming I contribute to global warming by driving a car daily around campus and also driving home every other weekend.
I also am part of the United States’ large population so I contribute to using more food, releasing more methane, and burning more fossil fuels. Slide 10: Solutions Invest in renewable energy
Increase efficiency of cars
Plant more trees
