Transcript:

Global warming is causing the Greenland ice cap to disintegrate far faster than anyone predicted. A study of the region's massive ice sheet warns that sea levels may - as a consequence - rise more dramatically than expected. Scientists have found that many of the huge glaciers of Greenland are moving at an accelerating rate - dumping twice as much ice into the sea as five years ago - indicating that the ice sheet is undergoing a potentially catastrophic breakup. The implications of the research are dramatic given Greenland holds enough ice to raise global sea levels by up to 21 feet1, a disaster scenario that would result in the flooding of some of the world's major population centres, including all of Britain's city ports. Satellite measurements of the entire land mass of Greenland show that the speed at which the glaciers are moving to the sea has increased significantly over the past ten years with some glaciers moving three times faster than in the mid-1990s.

According to the passage, what are the concerning implications of the disintegration of the Greenland ice cap due to global warming? Select THREE correct answers.

* Click on the correct answers

Sea levels may rise more dramatically than previously predicted. Some of the world's major population centers could be flooded. Greenland's ice cap is moving at a slower rate than expected. The increase in ice melt will lead to cooler global temperatures. Glaciers are moving at an accelerating rate, contributing to rising sea levels. The Greenland ice cap holds enough ice to potentially raise global sea levels significantly.

Result:

A.I. Explanation:

Option 1: "Sea levels may rise more dramatically than previously predicted."
Explanation: The text states that global warming is causing the Greenland ice cap to disintegrate faster than predicted, leading to a warning that sea levels may rise more dramatically than expected. This aligns directly with the main idea of the text, which emphasizes the alarming consequences of ice melt.
Option 2: "Some of the world's major population centers could be flooded."
Explanation: The passage mentions that the melting ice from Greenland could lead to flooding in major population centers, including Britain's city ports. This is a direct implication of the rising sea levels discussed in the text, supporting the concern about the impact of global warming.
Option 3: "Greenland's ice cap is moving at a slower rate than expected."
Explanation: This option contradicts the text, which states that glaciers in Greenland are moving at an accelerating rate, not a slower rate. Therefore, this statement is inaccurate and does not reflect the information provided.
Option 4: "The increase in ice melt will lead to cooler global temperatures."
Explanation: The text does not support this statement; instead, it discusses the consequences of ice melt leading to rising sea levels, not cooler temperatures. This option presents a misleading cause-effect relationship.
Option 5: "Glaciers are moving at an accelerating rate, contributing to rising sea levels."
Explanation: The text explicitly states that glaciers are moving at an accelerating rate and dumping more ice into the sea, which directly contributes to rising sea levels. This aligns with the main theme of the text regarding the rapid changes in Greenland's ice.
Option 6: "The Greenland ice cap holds enough ice to potentially raise global sea levels significantly."
Explanation: While the text mentions that Greenland holds enough ice to raise sea levels by up to 21 feet, this option is too narrow and does not address the implications of the ice cap's disintegration. It lacks the context of the consequences discussed in the passage.
