Name one consequence identified by the rise in global temperatures.

• A. Rising sea levels
• B. Decreased rainfall globally
• C. Increased volcanic activity
• D. Lower global temperatures

Answer: (A)

Rising sea levels are a direct consequence of global warming. When the planet warms, seawater expands as it heats (thermal expansion), and large amounts of ice on land—like glaciers and ice sheets in Greenland and Antarctica—melt and flow into the oceans. Together, these processes raise the average level of the seas. This is a well-documented and observable effect, with implications for coastal flooding, erosion, and saltwater intrusion into freshwater sources. The other options don’t fit as universal consequences of temperature rise. Global rainfall patterns don’t simply decrease everywhere; climate change is expected to shift where and how much it rains, with some regions getting more and others less. Increased volcanic activity isn’t driven by higher temperatures in the atmosphere or oceans; volcanic activity is governed by geological forces inside the Earth. Lower global temperatures contradict the premise of warming.
