Global Warming!

By: Briana & Shannon <3

DefinitionsGreenhouse Effect:

Naturally occurring process that helps the earth hear

the atmosphere and surface. It is a result from certain atmospheric gases

that are able to absorb radiation from the Earth’s surface. (Without it, life probably wouldn’t exist)

Climate Change: Seasonal changes

over a long or short period of

time.

Global Warming: An increase in Earth’s average temperature

due to harmful emissions or

deforestation that would trap hear that would usually escape from Earth’s surface.

Greenhouse Gases/Climate Change/Global Warming, Related?

• All have to do with heating and cooling of the Earth

• All happening right now• Burning fossil fuels pours out greenhouse

gases at a life-threatening rate and causing global warming

Primary Causes

• Increase in greenhouse gases, which traps heat in the atmosphere

• Humans are burning more fossil fuels

Possible Consequences

• Rising sea levels• Melting arctic sea ice• Warm winters• Rising ocean temperatures• Severe weather

Impact on Economy

• Polar caps melts along the Northwest Passage which makes for cheaper shipping costs

• Longer summers led to an increase in allergy season and increased health care costs for people with asthma and allergies

• Global warming increases the size and frequency of hurricanes, which means more money is needed to pay to fix the hurricane damage

• Some people invest a lot of money in stopping global warming

Ways We Can Fight It

• Let your representatives in Congress know you support federal action to reduce greenhouse gas emissions

• Turn down the AC when you leave the house• If you're not into getting a "recycled" appliance, buy one with the

Energy Star label• Put in compact fluorescent bulbs• Plug chargers into power strips with an on/off switch. A power strip in

the off mode uses zero juice. • Cool your home by planting a tree where the sun hits most directly.• Buy in bulk.• Use a ceiling fan for cooling a room.• Buy "recycled."• Don't use hot water when cold water would work too.

Basic Arguments Against It• Most scientists do not believe human activities threaten to disrupt

the Earth’s climate.• Our most reliable sources of temperature data show no global

warming trend.• Global climate computer models are too crude to predict future

climate changes.• The IPCC did not prove that human activities are causing global

warming.• A modest amount of global warming, should it occur, would be

beneficial to the natural world and to human civilization.• Efforts to quickly reduce human greenhouse gas emissions would

be costly and would not stop Earth’s climate from changing.• Efforts by state governments to reduce greenhouse gas emissions

are even more expensive and threaten to bust state budgets.• The best strategy to pursue is “no regrets.”

Personal Opinions

We believe that there is no global warming trend forming and that it will not affect human life on Earth. There are just a lot of myths about global warming but majority aren’t true. We also do not believe that humans are causing global warming.
