Arctic warming may lead to all of the following EXCEPT:

• A. Stronger storms
• B. Jet-stream disruptions
• C. Changes in precipitation patterns
• D. Faster moving hurricanes

Answer: (D)

Arctic warming tends to influence mid-latitude weather through changes in atmospheric circulation, especially the jet stream. As the Arctic warms more quickly, the temperature contrast with lower latitudes weakens, which can make the jet stream more wavy and cause it to linger or stall. That pattern can lead to stronger storms, disruptions in the jet-stream flow, and shifts in where and how precipitation falls. The idea that hurricanes would move faster isn’t a typical outcome of Arctic warming. Hurricanes are steered mainly by tropical and subtropical atmospheric currents and by sea-surface temperatures. Arctic changes don’t provide a mechanism that reliably speeds up tropical cyclone movement, and in fact altered steering currents could slow or erraticize storm tracks. So faster moving hurricanes isn’t a expected consequence of Arctic warming.
