Question

1. How does the melting of the polar ice cap affect the amount of energy absorbed from the sun?

2. How does the earth's climate redistribute heat from the equator to the poles?

3. In terms of ocean levels, what is the difference between the land-based ice and the seabased ice on Antarctica?

4. How much would the ocean level rise if the ice sheets on Greenlnd melted?

5. Of the 928 scientific articles on climate change, what percentage of those articles was in doubt as to the causes?

6. Of the 636 news articles in the popular press, what percentage was in doubt as to the cause of climate change?

7. What are the three misconceptions about climate change that Mr. Gore presents in his speech?

Explanation / Answer

1. the melting point of polar caps decides the ambient temperature below which the reflectivity of earth's surface will become very low or above which the reflectivity would be really high ( for white color of ice caps). Hence, if the melting point was higher, then there would be overall low reflectivity of earths polar caps as compared to the current low melting pint of polar caps

2. the heat is redistributed from equator to poles using ocean and wind currents

3. land based ice is present on the land and is at considerable height where as sea based ice is present on the water off the sea coast of antarctica and has presence deep into the ocean

4. ice sheets of greenland , if melted would give a large amount of influx of water into the oceans and this would hence contribute globally to a rise of sea levels to accomodate this extra amount of water. The gaint rock has the potential to raise world sea levels by 23 ft by a study
