What is a Glacier?

• Glaciers by definition are large masses of
  snow recrystallized ice and rock debris that
  accumulate in great quantities and begin to flow
  outwards and downwards under the pressure of
  their own weight. Glaciers form when yearly
  snowfall in a region exceeds the amount of ice
  and snow that melts in a summer. Massive amounts
  of material accumulate in very small periods of
  geologic time.

Glacier Pictures

• Before Global Warming Began
• This is a picture from ISS 009 196163921

The Current Changes in our Environment

• This topic is current to about 4 years, or since
  2003.
• The changes in this picture can be seen in our
  environment because in this specific glacier
  picture, the glaciers are almost completely
  frozen with pretty much no melting.

Glacier Information

• Glaciers are a huge part of our lives.
• They hold about 3 of our fresh water supply and
  they give polar bears a home.
• Due to global warming, these polar bears have
  been dying rapidly. The thin ice breaks as
  theyre standing on it and they fall in. The cold
  water is too cold, therefore they drown.
• The glaciers, if melted far enough, will flood
  out parts of our Earth, when already 70 of it is
  covered with water.
• Because of the ozone layer dissolving, the sun is
  getting more harsh on the Earth.

During Global Warming Conditions

• This pictures currency is about 2006.
• The conditions that can be seen in this picture
  are that the glaciers have melted drastically
  since 2003 and are continuously melting as we go
  about our daily routines.

Greenlands Huge Icecap

• The glaciers shown in this picture have melted
  rapidly since 2002.
• It was measured by NASA airborne radar laser and
  they appear to be thinning out and shrinking.
  This is also causing water levels to rise.
• Around the globe, sea levels have risen about 6
  inches higher in the last 100 years, thanks to
  warmer sea waters.

10
Who is Affected by Global Warming?

• Polar bears are affected, penguins, humans,
  plants, weather conditions (snow, rain, ect.),
  ocean life, and our air supply.
• All areas of the world are affected by global
  warming, especially the colder places like
  Iceland, Greenland, Alaska, and all of the oceans.

Greenlands Glaciers Continued

• Glaciologist Dr. Mark Meier was interviewed in
  2002 about his estimations on sea level. He said
  that according to his thoughts, 0.65 feet of
  water or more could be added to our oceans in
  this century.

Why is it important to know the effects of Global
Warming?

• It is important to know the effects of global
  warming because if we dont stop polluting our
  earth, the temperatures will rise dramatically,
  animals will die, and even generations to come
  will not see the animals that we have the
  privilege to see today. PLEASE DO YOUR PART TO
  PREVENT GLOBAL WARMING!!!

This is what will happen...

How Can We Help With Global Warming???

• We can help with global warming by carpooling,
  throwing away our trash in the proper disposable
  cans, recycling, trying to cut down on aerosol
  sprays, and dispose of chemicals in proper
  disposable cans.

We will BURN !!!
