Read the following passage and answer the question below. Glaciers, massive bodies of ice formed over thousands of years, are melting at an accelerating rate due to rising global temperatures, posing serious consequences for both local ecosystems and the wider world. Many communities around the globe depend on glacial meltwater for drinking water, agriculture, and hydroelectric power, particularly during dry seasons when other water sources are scarce. As glaciers shrink, these communities face growing uncertainty about their long-term water supply. Beyond regional impacts, the melting of large ice sheets in Greenland and Antarctica contributes significantly to global sea level rise, threatening coastal cities and low-lying island nations with increased flooding and erosion. Scientists use satellite measurements and on-the-ground observations to track glacier retreat, and the data consistently shows accelerating ice loss across most of the world's glaciated regions. Addressing glacier melt is closely tied to broader efforts to reduce greenhouse gas emissions, since the rate of melting is directly influenced by global temperature trends. Question: According to the passage, which regions' ice sheets significantly contribute to global sea level rise?
- A. Greenland and Antarctica ✓
- B. Siberia and Canada
- C. The Alps and the Rockies
- D. The Himalayas and the Andes
Correct answer
A. Greenland and Antarctica
Explanation
The passage specifically names Greenland and Antarctica as contributing significantly to sea level rise.
