Transcript of Ice Berg

What is Iceberg Warming
Icebergs are pieces of ice that formed on land and float in an ocean or lake. For an iceberg to be considered an "iceberg," it has to be at least larger than 5 meters across. When these gigantic chunks of ice melt, it has devastating effects. Many arctic animals use the ice to survive. Polar bears for example, use the ice to hunt seals, and live on. Without the ice, these precious animals will slowly start to become extinct.
Iceberg Warming Statistics
On August, 26 the Arctic sea ice cover fell to 4.1 million square kilometers
Studies show that one of the main reasons ice shelves are breaking off in Antarctica, is because warm water is softening the ice
A research team found that 55% of all ice shelf loss between 2003-2008 was much higher than anyone thought.
A study team estimated the Antarctic ice shelves in total lost almost 3,000 trillion pounds of ice each year during the time frame they studied due to melting underneath, and about 2,400 trillion pounds due to iceberg formation.
The Egg Code on the ice charts defines the concentration, stage of development, and forms of ice.
Reasons & Effects of Iceberg Warming
Reasons:
Warm Waters
Global Warming
Pollutants

Devastating Effects:
Arctic species extinction
Dangerously high sea levels
Changes in weather patterns
Environmental & Economic
Impacts
Economic:
Many arctic species would die off, not giving people who live in this region food.
The sea level can become very high, and flood areas around it
Environmental:
Many arctic species could become extinct
The sea level can become to high
There can be massive floods

5 Questions
Who discovered iceberg warming?
How do icebergs warm up?
Where does iceberg warming typically happen?
What is the most popular way for icebergs/icecaps to warm?
Why do icebergs melt?
Hypothesis
If iceberg warming does not get better, many arctic species may soon become extinct.
Can we fix the Issue?
This issue can be resolve. There would be many great impacts if we were able to find a way to lower the rate at which icebergs melt. Many species in the arctic would survive, and be able to have a home. People living in the arctic would no longer have to live in fear of a flood coming, and a catastrophic amount of people loosing there life. The issue can be fixed, and great things would happen. If we do not do this, there would be to many things that could happen. If we want to survive, there has to be a solution to Iceberg Warming.
How are humans directly involved with the issue?
Humans directly impact the issue of iceberg warming in many different ways. Because of global warming, caused by green house gases. Global Warming makes the oceans much warmer than they should be causing the ice to get soft, and eventually break apart. The catastrophe of the entire ice shelf melting could cause unthinkable problems, and disasters. Because the sea level would rise to such a great level, this would allow gigantic hurricanes to crash into places all over the world, killing millions. Humans can reduce greenhouse gases, making the temperature cooler and not making the water so warm.
Question & Hypothesis
Answers
Who discovered ice cap warming?
There is not an exact person who discovered iceberg warming. It was more like because of global warming scientists all around the world started to notice a decrease in the amount of ice on the polar regions.
How do Ice caps warm up?
Icebergs warm up by the sun directly hitting them, land melting the ice berg. These gigantic pieces of ice get soft because of global warming, and eventually change their current state of matter from a solid to a liquid
Where does ice cap warming typically happen?
Iceberg warming typically takes place in major polar areas. These areas tend to be very far from the equator and very close to the North and South Poles.
What is the most popular time for ice caps to warm?
There is not a specific time of the year that it is most popular for ice bergs to warm. However, you coould say that there was a certain period in time when icebergs started to melt more rapidly. This period of time was when the Industrial Revolution began. This revolution created more pollution to the air, causing the start of global warming.
Why do ice caps melt?
Ice bergs melt when they absorb heat (thermal energy) from sea water and from the air. Direct sunlight is largely reflected off them. Heat, just like an ice cube, heat cause the internal temperature to raise, which causes the ice berg to melt on the outside.
Hypothesis
How does iceberg melting impact climate change
Iceberg melting impacts climate change in many different ways. One of the many ways is that it causes many more hurricanes, and storms.
Research
Global Warming
In many places around the world, precipitaion on average has increased.
The sear level is expected to rise 7-23 inches by the end of the century.
Hurricanes and other storms are expected tp become stronger
Less fresh water will become available.
Many more diseases will spread such as malaria, carried by misquitoes.
Sea Levels
Over the past century sea levels have risen 4-8 inches
The rise of the sea level is linked to three factors:
Thermal Expansion: when water heats up it expands
Melting of polar ice caps: When the ice caps melt, they add to the amount of water in the ocean. This rises the sea level.
Ice loss from greenland and Antartica: When the the glaciers and ice sheets that cover Greenland and Antartica melt, they melt at an accekerated pace.
As the sea level rises, it causes more flooding and natural disasters.
A recent study says we can expect the oceans to rise between 2.5 and 6.5 feet (0.8 and 2 meters) by 2100, enough to swamp many of the cities along the U.S. East Coast.
Animal Crowding
Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
Many areas in the arctic have been overcrowded with animals, because so much ice is melting that there is no where for them to go but crowd with others animals.
Based on my research, I can assure you that my hypothesis is scientifically, and factually correct. Like I had said earlier, in the last century the sea level has risen 4-8 inches. This number is so high because, with global warming, it has warmed the ice and changed its state of matter to sea water. This extra sea water has majorly increased the sea level. Because of the rise in the sea level, many animals in the arctic have crowded into habitats, not allowig any room. If the sea level rises too high much more aggresive storms will come, wiping out many arctic species making them extinct.

Why Should the Issue be Fixed?
The issue must be fixed. Animals every day are drowning, and loosing their homes because of this horrible thing. If this issue can't be resolved, disasters are going to come. If icebergs continue to melt at such a rapid pace, the sea level will be higher causing worse storms than Hurricane Sandy. Entire communities will be washed away by these massive superstorms. National Geographic states that sea levels are expected to rise anywhere between 7-23 inches by the end of the century. This is a catastrophic problem in our environment right now. This problem must be dealt with before to many devastating events occour.
