What can we do to offset our carbon emissions?

Use and Production of ElectricityCarbon footprint: The amount

of carbon dioxide for which an individual or group is responsible

70% of electricity in the U.S. is generated by burning fossil fuels.

Reducing electricity use reduces carbon footprints.

Ways to reduce electricity use:

Use energy-efficient technologies, which lessen the electricity needed to do a job.

Reduce the use of electrical devices and appliances.

Alternate Sources of Electricity*

Alternative Sources of Electricity

Nuclear powerSolar powerWind powerHydroelectric powerGeothermal power

Wind turbines

Advances in Vehicle Technology Transportation is the second largest source of

greenhouse gas emissions in the United States, second only to electricity.

Alternatives to fuel-only cars include:

•Gasoline-electric hybrid vehicles• http://www.youtube.com/watch?v=LV2W36fPWng

•Vehicles that use alternative fuels such as compressed natural gas

•Vehicles that use hydrogen fuel cells.*

Reducing Dependence on Cars Biking, walking, and using public

transportation are all ways to reduce fossil fuel use.

Many communities lack good public transportation.

Did You Know? The average American family makes 10 trips by car each day.

How else can we reduce greenhouse gas emission?

Strategies for Reducing Greenhouse Gases

Agriculture / forestry: Reduce soil erosion and replace cut trees, to curb CO2 emissions

Cap-and-Trade: System of emission allowances that can be sold or traded, gives companies incentive to reduce emissions*

Carbon tax: A tax per unit on emissionsCarbon offsets: Instead of directly reducing

emissions, companies can make a voluntary payment to a group that reduces or curbs greenhouse gases.

Carbon sequestration: Technology is used to trap and store carbon dioxide emissions.

Environmental Science Verbal Drill

You must answer if the toy is passed to you. (Points deducted from your weekly participation grade if you refuse.)

If you don’t know the answer, look it up in your notes or discuss it with a classmate. (i.e. don’t just ask for the answer)

If the class reaches 25 points, extra points will be given on the next unit exam.

The class will have 3 minutes to earn as many points as possible.

Lesson 16.1 Our Dynamic Climate

Without greenhouse gases, Earth would be too cold to support life.

Greenhouse EffectThe greenhouse effect is a natural process

in which certain gases keep heat near Earth and prevent it from radiating into space. The main greenhouse gases are:

1. Water vapor

2. Carbon dioxide

3. Tropospheric Ozone

4. Nitrous Oxide

5. Methane

The Greenhouse Effect

A natural process in which greenhouse gases absorb heat and release it slowly back into the atmosphere

Greenhouse gases do not trap energy that has been converted to heat at Earth’s surface.

Did You Know? Greenhouse gases absorb heat and release it slowly, while an actual greenhouse traps warm air inside a structure.

The Effect of Latitude• Latitude is a

measure of a place’s distance from the equator.

• In general, the greater the latitude, the cooler a location’s overall climate will be.

• The seasons are also caused by the changing angles at which sunlight strikes Earth.

HW #2

Wind Patterns in the Atmosphere

Caused by convection currents resulting from rising warm air and falling cool air

Transports moisture and heat Global wind patterns move warm air

away from equator, toward poles. Cold air moves from poles toward

equator.Winds pick up moisture and can carry it for

long distances until it falls as precipitation.

Check For Understanding

1. What are convection currents?

2. Cold air normally travels from where to where?

3. Warm air normally travels from where to where?

The Oceans and Climate

Ocean currents, which are caused by a combination of unequal heating of water and unequal salinity, affect climate by transporting heat.

El Niño and La Niña are disruptions to normal climate patterns caused by variations in the typical interactions between the ocean and the atmosphere.

Did You Know? The ocean absorbs a lot of carbon dioxide, causing a global cooling effect. The ocean can hold 50 times more CO2 than is found in the atmosphere.

El Niño

NORMALLY = prevailing winds travel from EAST to WEST along the equator

El Niño is a disruption to normal climate patterns caused by variations in the typical interactions between the ocean and the atmosphere.

Other Factors That Affect Climate

TOPOGRAPHY

•Topography describes the surface characteristics of the area, including its altitude (how high) and features such as mountains, rivers, and lakes.

•Higher altitudes have cooler temperatures; mountain ranges affect rainfall patterns.

• .

•Gases and particles can temporarily block sunlight, causing air to cool.

VOLCANOES

•Vegetation: Plant life promotes cloud formation and absorbs carbon dioxide.

•Earth’s orbit: Changes in Earth’s orbit and the tilt of Earth’s axis affect the distribution of solar radiation
