Melting Polar Ice Caps
What is a polar ice cap?
We can stop it by changing our transportation, energy consumption, and food choices!
How can we stop it?
We can carpool, walk, bike, or take pubic transit.
Turning down your heat. (For example, in the winter put on warmer clothes rather than turning up the heat.) Turning off unnecessary appliances and lights. Use energy efficient light bulbs and appliances.
By eating more organic, local, and seasonal foods. Properly disposing of all waste from foods ( Keeping landfills empty.)
Global warming is the increase of Earth’s temperature due to greenhouse gases, that traps heat that would otherwise escape the Earth.
What is Global Warming?
Melting ice caps & global warming
Global warming is a huge problem caused by our melting ice caps.
Earth’s polar ice caps reflect a lot of light back into space, because of their high albedo value.
When ice melts, it’s albedo value decreases because the ice becomes more dull. Since our polar ice caps are melting, and their albedo value is decreasing, less light is being reflected back into space, resulting in Earth’s temperature increasing.

A polar ice cap is a large area that is covered by ice and snow, the Earth has two located at the North and South poles.
These rising temperatures are not only affecting the polar regions, they are affecting the entire world. For example, a spruce bark beetle breeds much faster in warmer weather. Global warming is causing Alaska’s temperature to rise, and is resulting in an outbreak of spruce bark beetles. This is a problem because these beetles can destroy forests.
The melting ice caps are affecting the animals and they are going extinct. The reason is because the ice that is remaining is farther from shore,which is making it more difficult to get to. The larger the gap between the ice caps and land, the rougher the wave conditions. Which is why it is making it more hazardous for the polar bears and any other animals that swim.

the largest single block of ice in the Arctic, the Ward Hunt Ice Shelf, had been around for 3,000 years before it started cracking in 2000. Within two years it had split all the way through and is now breaking into pieces.
Maintaining the Earth’s temperature is important because most animals that live in very cold temperature depend on the frozen and mostly covered snow and ice grounds.
In the Greenland ice cap ares melting so fast that is triggering earthquakes, since pieces of ice several cubic kilometer in size break off and fall into the water.
[T]ransportation accounts for almost half of noxious air pollution, more than a third of greenhouse gas emissions, one quarter of common air contamination and almost one-fifth of water toxicity
Today, there are now existing cars that burn little to no gas.
The Canadian government has ‘Auto Smart ratings’ that define whether or not a car is fuel-efficient and doesn’t emit a lot of pollution.
Canada is the largest consumer of energy in the world on a per capita basis
There are so many humans on the planet, simply feeding ourselves has led to all kinds of environmental havoc — air and water pollution, loss of soil and reduced biodiversity.
