Climate and controlUnit 7. 9

• Megan Johnson, Lauren Kendrick, AND Wesley Argular

• K.SDo you care about Global Warming?

• T of C…Day 1 of Climate control

Introduction to Global Warming

• What is Global warming? Why should we care? How is going to effect us?

• It can help us live : )

• Here is how….

Why we care …

This is why! Because of the greenhouse gases that absorb outgoing, long wave, radiation and reradiate some of this energy.

• Approximately 50% of the percent of the solar energy that strikes the top of the Atmosphere reaches Earth’s surface and is absorbed while some get reflected back into space.

• The earth is surrounded by layers of sphere’s that protect us from harmful Ultraviolent Rays (UV Rays) also known as the Ozone layer: This is an important component of the atmosphere where it absorbs harmful UV Rays.

Our solution? We don’t quite know yet…

• Greenhouse Effect: This occurs when the earth is not a suitable habitat for humans and other numerous life-forms.

• Because of the deteriation of the ozone layer more UV Rays are able to get through the atmosphere and cause different climate changes.

• For example, the ice glaciers in Antarctica and the animals that live there are suffering quite a bit because of melting ice=no home to live on.

Some ideas…

What contributes to Global Warming?

• An overwhelming amount of combustion from factories and production of machinery, cars, etc.

• The air and what we put in it. • The air is composed mainly of two gases,

78% of Nitrogen and 2% oxygen, but there is also Argon (1%) and Carbon Dioxide (.035% after respiration)

• Oh, and US! (humans)

Our main problem is CO2! According to New York Times, “The great hope was that the

technology would prevent much of the world’s largest source of greenhouse gas emissions from reaching the atmosphere.”

The more carbon dioxide we have the more climate changes occur and temperatures rise thus creating an increase in Global warming.

Many people have different opinions about this making it a public debate (for or against).

It’s a HUGE deal.

What can we do?

• Reduce how much electricity we use, decrease pollution, become “Eco-friendly” in simple terms.

• Use anything that uses less energy.• http://www.youtube.com/watch?v=_Z

END OF DAY 1

T of C:Day of Wesley

K.S:What do you know about the hemispheres?

How the specific heat of certain areas affect said

area’s ocean life

Specific heat

• Is the amount of energy needed to heat one gram of a substance one degree Celsius

• So the more energy that is needed to raise the temperature the higher specific heat so for example iron would have a low specific heat and air would have a higher specific heat but land has a higher specific heat then air

The Hemispheres

• Water hemisphere• Also known as the southern hemisphere for the

greater amount of water in this area• The southern hemisphere has a high specific heat

so it heats up slower so the ocean life in this area are not that effect by the changing ocean tempter

• The southern hemisphere is heated up by convection and radiation

The Hemispheres

• Land Hemisphere- • Also known as the northern hemisphere for the

greater amount of land in this area and land has a low specific heat so it heats up faster then southern hemisphere

• The ocean life is this area is affected more by the changing ocean tempter

• The northern hemisphere is mostly heated up by conduction with the help of radiation

END OF DAY 2

T of C:

K.S.:Where does Nemo live?

We will know….

The consequences of changing ocean temp on, Hurricanes, Coral

Bleaching and Sea levels

What is the oceans role in our climate?

The ocean covers is our 71% of our earth. It is largest climate control unit.

The ocean’s job is to absorb, store and slowly release heat over time

How does the ocean heat the whole earth?

What does that have to do with heat and global warming?

OCEAN ACIDIFICATION.The ocean is the greatest CO2 reservoir, 50x’s greater than the atmosphere. Ocean acidification is when CO2 dissolves into the ocean raising levels of acidity.

Who is affected?Coruscations, plankton, krill, fish, sharks whales, humans, EVERYONE

Coral bleaching and weather.

How is a hurricane formed?“Hurricanes are intense low pressure areas that form over warm ocean waters in the summer and early fall. Their source of energy is water vapor which is evaporated from the ocean surface. ”

Why do coral reefs matter?

Highest biodiversity PERIOD.

Economic factor.

Most vulnerable.

Coral bleaching is when the plant like bacteria that gives coral reefs their color and life evacuate due to unbearable living conditions.

END OF DAY 3

T of C:Climates

K.S.-List 2 climate zones you can think of.

Classifying Climates

WWK how to classify climates

and how to use present

climates.

What is a climate and what is a climate system?

Climate

The average weather conditions of a certain place or region

Climate system

Exchange of energy/ moisture that occur among the atmosphere, hydrosphere, solid earth, biosphere and cryoshpere

How are climates classified?

• By judging humidity, average temperatures of certain areas, rainfall, amount of snow, ect.

• Different methods using different strategies have been developed. Bergeron and Spatial Synoptic (judges on air masses), Köppen (judges on monthly values of precipitation and temperature), and Thornthwaite (judges on how much water is used to nourish a certain area of soil). Köppen is the most common and easiest to use.

The Köppen Classification Method

• Splits climates into 5 different categories: Tropical (generally warm, humid environments with diverse vegetation and animal life. Rich soil), Dry (generally desert areas with little vegetation and only a handful of animals. Sandy soil), Mild Mid-Latitude (goes through seasons but tends to be slightly warmer year round. Vegetation, and animal life vary), Cold Mid-Latitude (seasons but tends to be cooler than average. Vegetation and animals vary), and Polar (Antarctica).

How does global warming affect climates?

• Global temperatures have been getting slightly higher year to year. Carbon Dioxide emissions could cause the temperature change to shift more drastically and alter the climates and put certain vegetation in danger.
