What Can We Do?

What are some ways we can prevent global warming from speeding up?

1. Recycle.
The more we recycle, the less emissions companies will send into the air. With the lack of need to create product, the less they'll be running.


2. Moniter our vehicle use.
Do we really need to use our vehicles all the time? With other options like the bus, cabs, and carpooling, we have no need to be using our vehicles all the time. If you need to run to the corner store to grab a jug of milk, walk. If you want to go to the river for a walk? Walk there too. By cutting down our use of vehicles we'll cut down on the emissions we use.

3. Use less Heat/ Air Conditioning
Did you know that by adding insulation to your walls can attic can reduce your heating costs by 25%.
Setting your thermostat even just 2 degrees lower in the winter and summer can save around 2,000 pounds of carbon dioxide every year.

4. Use Less Hot Water

5. Plant a tree
When photosynthesis occurs it'll take away the carbon dioxide and create more oxygen.

6. Turn Lights Off.
When you leave a room, remember to turn off all things that may use electricty. Things like the TV, lights, unplug your laptop, cell phone chargers, ect.

7. Reuse your shopping bags.

8. Buy organic and local foods.



Stories of Global Warming

From reading these stories I've learned that global warming is much more serious then we thought, and is moving much more rapidly then expected. If we don't change our ways our Earth will deteriorate before our eyes.

Effects of Global Warming

http://www.youtube.com/watch?v=oJAbATJCugs







Global Warming is affecting the Artic because its melting the ice and the glaciers leaving the animals with no where to go.




Global Warming, Defined.

Global Warming: The rise of temperature in the Earths atmoshphere and oceans.



This graph shows the changing temperatures over the years.


Climate Model Projections:

Global Temperature: Temperature is going to increase

Global Precipitation: precipitation will inrease in tropical regions,

Precipitation extremes and droughts: Greater risk of droughts, and an increase in precipitation.

Snow and Ice: Snow cover and Sea ice will decrease, ice caps will lose mass and begin to melt.

This cartoon is describing the effects of the snow and ice regions melting and which animals will be affected.



Common Weather Folklore and Proverbs

"Clear moon, frost soon."

"Halo around the sun or moon, rain or snow soon."

"When the stars begin to huddle, the earth will soon become a puddle."

"Rainbow to windward, foul fall the day; Rainbow to leeward, rain runs away."

"Seagull, seagull, sit on the sand, It's a sign of rain when you are at hand."

"The moon and the weather may change together, But a change of the moon, will not change the weather."

" When grass is dry at morning light, Look for rain before the night. "

" Chimney smoke descends, our nice weather ends."

" The farther the sight, the nearer the rain."

" The first and last frosts are the worst. "



We can't believe in these proverbs because their is no phsyical evidence of these being true. These are much like other folklore myths. For example the ground hog.

Meteorology and Weather Prediction

Radar-
       Uses electromagnetic radiation to sense precipitation.


Satellite-
       Uses infrared images to show cooler temperatures and warmer temperatures

Weather Fronts and Systems




Fronts: The boundaries between air masses of different temperatures.
Warm Front: When warm air is moving toward cold air this is a "warm front"
Cold Front: When cold air is moving toward warm air it is a " cold front"
 
When neither the cold air or warm air is moving this is called a " stationary front"

Wacky Weather

Mirages: A mirage is the image of an object or a sky where it is not present. This is caused when light is refracted, often mirages are seen on hot surfaces like a pavement or desert.

Mammatus Clouds: Mammatus clouds are odd-shaped clouds that are often seen before a storm. It is still unsure of how they form.

Firewhirls: A firewhirl is what happens when a tornado is spinning too close to a forest fire or it can be a whirl created from too much heat in the area.

Weather advisorys are classified by three colors. Red for warning, yellow for watch, and green for just ended.

Here are some videos on current weather events:

The Atmosphere

The Atmosphere

Our atmosphere is made up of five layers. The Troposphere, Stratosphere, Mesosphere, Thermosphere, and the Exosphere.
 
The troposphere is the first layer of the atmosphere. It begins at the surface and extends 10 km.
Within the troposphere, 80% of the atmospheres mass is located here.

The stratosphere is the second layer of the atmosphere. The temperature increases with height because of the increased absortion of ultraviolet radiation from the ozone layer.

The mesosphere is the third layer of the atmosphere and this is the layer where most meteors burn when entering the atmosphere. Unlike the stratosphere the mesosphere decreases temperature with height. Due to such cold temperatures, ice clouds form in the mesosphere.

The thermosphere is the fourth layer of the atmosphere.

The final layer of earths atmosphere is the exosphere. It is mainly composed of hydrogen and helium. Particles in this part of the atmosphere are so far apart that they can travel hundreds of km without colliding with one another.

Ozone Layer.

The Ozone layer is the layer of ozone gas in the upper atmosphere. This gas plays a huge role is protecting humans and other things from the harmful ultraviolet rays of the sun.
In 1977, scientists discovered that man made chemicals had the potential to destroy the ozone layer, and this a problem we are now facing in modern times. Slowly, the ozone layer is disappearing.

Weather and Climate

Weather and Climate



Weather: Weather can be described as the atmosphere at a certain place and time regarding the heat, cloudiness, dryness, wind, rain, sunshine, snow, ect.
Climate: Climate can be described as the weather conditions showing in a general area over a long period of time. For example, the climate in Mexico can be described as hot, humid, and dry.
The climate in Ireland can be described as moist, mild, and changeable with abundant rainfall.

Why The Weather?
People all around the world have a high interest in the weather because of it's ever changing state. All around the world people take interest in the weather and why it changes. Day to day the weather can change at an instant, for no reason at all. If a volcano erupts, it often affects the weather in many different parts of the world. When a tsunami hits, it too affects the weather in different continents. Our world needs balance and when something throws it off, one of the outcomes is the changing of weather.
