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 MexicoWarmer seasConcern of melting glaciers raising sea levelMore mosquito borne diseasesHurricanes to be stronger and more

dangerousMakes wild firesUnited States largest source of global

warmingEarth 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
