Global Warming: The Ice Age

What is an ice age?

An ice age is a period of long term reduction in the temperature of Earth's surface and atmosphere, resulting in the presence of expansion of continental and polar ice sheets and airplane glaciers.

Ice Ages in Earth's Past

1. Huronian

2. Cryogenian

3. Andren- Saharan

4. Karoo Ice Age

5. Quaternary Glacition

Facts About The Ice Age

The events leading to an ice age were so severe, that even if the atmosphere was full of greenhouse gasses, ice still begins to form because after the pollution gets thick enough, it might bounce the Sun's rays back in space.

4. A "Warm Ice Age"

Some ice ages were believed to be pretty warm. The ground was covered by ice, but the weather was pleasurable. It was often called a giant "Baked Alaska" dessert (cold on the inside, and hot on the outside).

*An ice age has always been a mystery to us. It seems incomprehensible that ice covered 30% of the land surface.

1. "Giant Animals"

The animals that developed on an ice age were large and fur-covered. They survived the cold climate because they already evolved in freezing places like Tibet. Ice ages were their "playground", as other less cold resistant animals died out

Facts About The Ice Age

Science is still aspiring to figure out what causes "little ice ages", which might be a combination of heavy volcanic activity during the era and a temporary drop in the Sun's solar energy.

3. "Little Ice Ages"

At times, mini ice ages develop between the actual, large scale ones. Little ice ages are not quite as devastating but can still cause famine and disease due to failed crops. The most recent little ice age occurred around the 12th and 14th century. Years without summer were recorded and weather conditions influenced life and culture

9. "Snowball Earth"

A snowball Earth is the ultimate deep freeze, where a single part of the planet's surface is frozen. Little life can survive a total freeze. This has believed to occur about 716 million years ago.

Complicated weaponry was rare because hunting tools at the time were mainly stone knives and arrowheads. Traps were used to hunt and catch animals for food.

2. "Ice Age People"

Brave Homo Sapiens have been through the chilly tundras of ice ages for countless millennia. 15,000 years ago, ice age people lived in hunter- gatherer tribes. These tribes built innovative shelters from mammoth bones and sowed warms coats from animal furs.

10. The Garden of Eden

Some scientists are extremely convinced that the Garden of Eden was real. It was believed to be located in Africa for people to survive an ice age. A small band of early humans was able to last throughout the cold. They stumbled upon South Africa. The human population in the Garden of Eden was thought to be just a fewhundred individuals.

6. Human Pollution Could Avert The Next Ice Age

There are theories that ice ages repeat themselves at semi- regular intervals. The release of carbon dioxide are a huge problem regarding global warming today. Carbon dioxide might be able to stop the next ice age. The only way an ice age can begin is if the carbon dioxide levels of the atmosphere are exceptionally low.

7. "Ice Age Plants"

There were many plants that could endure the severe weather of the ice age. Grassland and shrub land areas allowed mammoths and other plant eating animals their source of nourishment. If a plant was not able to adapt to their environment, it's only option were to migrate via seeds or extinction.

5. Louis Agassiz

Agassiz is the sole reason we know about the ice age. In 1837, he was the first person to in introduce the idea of a past ice age. His ideas were dismissed once primarily introduced. He continued with further research and eventually caught the attention of critics.

8. Himalayas May Have Caused An Ice Age

Mountains are known for causing avalanches. When India and India collided 40-50 millions of years ago, the impact munched up massive amounts of stone into the mountain range. Fresh stone was exposed to the elements. A process occurred that removed carbon dioxide from the atmosphere over time, causing an ice age
