TRANSCRIPT
What is Global Warming?
An average raise in the temperature of atmosphere close to the Earth’s surface which can contribute to the changes in the global climate patterns.
What Causes Global Warming?
Carbon dioxide Factories producing
cement, steel, aluminum Power Plants Agriculture Landfills These are some of the
problems causing serious pollution
Acid Rain
! 98% of SO2 and NOX
emissions
! Acid rain is rain or any other form of precipitation that is unusually acidic.
! Acid rain is mostly caused by human sulfur and nitrogen emissions.
Reducing Acid Rain
! Clean up smokestacks and exhaust pipes
! Use alternative energy sources
! Take action as an individual by turning off appliances, insulate your home, carpool, have vehicles with low NOx and be well informed.
Tree Rings
Tree rings grow annually with a light layer in the spring and a dark layer in the autumn
How well the tree grows is dependent upon how much water, light and pollutants the tree receives
Uses of Tree Ring Samples
Very reliable Used by archaeologists
to chart annual rainfall, temperature, and forest fires
Used by NASA to plot annual changes in weather and pollutants
Our Tree Ring Example
Our tree ring is about 58 years old
It grew quickly for 4 years, then less for its remaining lifetime
For the last 10 year portion of its life, it shows a drier climate, resulting in slower growth and drier wood
Pollutants from acid rain could have caused its slower growth as well as the warmer climate
This could be because it lived by the side of a road that gradually got larger and had more vehicles on it
Global Warming will cause… Rising sea levels flooding on the east coast
and Gulf of Mexico Warmer seas Concern of melting glaciers raising sea level More mosquito borne diseases Hurricanes to be stronger and more
dangerous Makes wild fires United States largest source of global
warming Earth has been getting hotter over the past
50 years
Things That Can Stop Global Warming
Use fluorescent light bulbs instead of incandescent light bulbs
Use solar panels
Use wind energy, create wind farms
Reduce vehicles that run on gas
Reduce power plants
Conserve energy
