Some people fear that global warming will cause the large ice formations in the polar seas to melt, thereby warming the waters of those seas and threatening the plankton that is crucial to the marine food chain. Some scientists contend that it is unlikely that the melting process has begun, since water temperatures in the polar seas are the same today as they were a century ago.

What weakens the scientists contention?

A) Much of the marine plant life that flourishes in the polar seas will die in the event that the water temperatures rise above their present levels.
B) The overall effect of the melting process will be an increase in global sea levels.

C) The mean air temperature above both land and water in the polar regions has not varied significiantly over the past 100 years
D) The temperature of water that contains melting ice tends to remain constant until all of the ice in the ice-and-water mixture has melted

E) The mean temperature of ocean waters near the equator has remained constant over the past 100 years.

D) is saying after the ice melted, the temperature may or may not rise?

Mciatto, thanks for your contribution. But, without explanations, nobody benefits.

It is D - the scientists are claiming that the warming has not yet begun because the temperatures have not yet risen. Choice D says that the temperatures will not rise until after all the ice has melted - therefore the melting may have already begun, just that nobody will notice the temperature change until it is finished.

The word 'begun' is the key here.

People fear global warming = ice will melt = polar sea water temperature will rise

Scientists say polar water temperature same for last 100 years = ice not melting

Now only D is relevant as it presents a case where the causality specified in the scientists' argument might not hold

Used the same logic. Surely the polar ice-caps have already begun melting, scientists just wont be able to detect a change in water temperature until they fully dissolve.

D with the same reasoning.
