Consider the following statements regarding the impacts of Arctic warming:
1. Arctic warming can weaken the polar vortex, potentially leading to colder winter conditions in mid-latitude regions.
2. Arctic warming can weaken the jet stream, resulting in more persistent and extreme weather patterns in mid-latitude regions.

Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2

ONLiNE UPSC · Accepted Answer

Statement 1 is correct: Arctic warming can weaken the polar vortex, potentially leading to colder winter conditions in mid-latitude regions.

Statement 2 is correct: Arctic warming can weaken the jet stream, resulting in more persistent and extreme weather patterns in mid-latitude regions.
These changes in atmospheric patterns are associated with Arctic amplification, where the Arctic warms faster than the global average, influencing weather extremes in mid-latitude regions.
