Antarctica's Ice Cap Crisis By Eli Wizevich Britain's population has increased from 6 million to 14 million. All over the world the populations are enlarging and those people are burning fossil fuels and polluting. Burning fossil fuels creates pollution like carbon monoxide. As the CO2 rises, it is collected in the Earth's atmosphere. Although some CO2 helps keep the Earth warm, this is what we call the Greenhouse Effect, too much CO2 will make Earth too hot. In other words, this extra CO2 leads to global warming. The warming is causing the ice in the polar regions to melt and may lead to the the ice cap melting crisis.

The South Poles problem seems less popular than the Arctic's but all things accounted for neither are good. When the ice melts it hurts the environment and the animals.

What Animals are getting hurt due to this?
Adelie penguins
Gentoo penguins
Plants (Over the years the plants have been moving all over the peninsula.) Causes mapsof.net Antarctica's Problem photography.nationalgeographic.com What Can We do to Stop it? To stop it us humans can stop doing these things
Stop driving as many cars.
Don't use more water in the shower than needed.
Turn off electronic devices when done.
Those are only a couple things that you can do. Everything counts towards a better planet. What is the effect of the Ice Cap Melting? When the ice melts it turns back in to water. The Earth is 75% water and if it melts to fast it will cause the sea levels to rise. When the sea levels rise scientists predict that some coastal cites will be underwater if the pace that we are at now increases. Antarctica has ninety % of the worlds ice. If all the ice were to melt then the sea levels would increase by 260 feet or 80 meters. People pollute environment and create CO2 The CO2 rises and is trapped in Earths atmosphere The CO2 creates heat. The heat creates global warming. The ice caps melt and reduce due to the heat. Antarctica covers million Sq kilometers of land and contains almost million cubic kilometers of ice. Every day some of this ice is shrinking. Glacial Rebound The monstrous weight of the ice sheets depresses the Earth's crust, but if the ice were to melt then the crust would rise to original level. This is called the "Glacial Rebound. Is this melt natural? Glacial Geologists have noticed that there have been four or more major advances the past and then retreats of continental ice sheets over the past 2 million years. These are natural effects. Less Ice, more Vegetation As the temperatures rise ice melts and plants start to grow. Right now they are covering Palmer Land. They also so are on some small islands like South Shetland Islands. Some Plants that grow in Antarctica are like this Cycle of the Melting Climate Change Over the years there have been significant temperature changes of 3 to 6 degrees. In the Northern Hemisphere the 1990's were the warmest decade. 1998 was the warmest year. This is due to climate change. Thanks. Prezi
