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
