CLIMATE CHANGE

The Oceans Are Getting Warmer

by Katharina Buchholz, Jun 8, 2022

 

Annual average temperatures of the oceans’ surfaces have been diverging from the 20th century (1900-1999) average more and more since the 1980s. In 2021, global ocean surface temperatures were 0.65 degrees Celsius higher than that century’s average, according to the National Oceanic and Atmospheric Administration (NOAA).

While the annual divergence fluctuates (as some years happen to be hotter and others colder), there is still a definite upwards trend visible in the data. The year with the biggest divergence on record was 2016, when measured ocean temperatures were 0.8 degree Celsius higher than the stated average.

The global data for near-surface temperatures comes from ships, buoys and satellite measurements of the oceans. While fluctuations are a normal phenomenon, an increase of the number of years that are warmer on average is expected due to climate change, which is the increase of global average and mean land and ocean temperatures. According to scientific findings, the continuing global warming will lead to changes in the strength, frequency, spatial extent and duration of extreme weather events.

 

DESCRIPTION This chart shows global ocean surface temperatures from 1880 to 2021 as a divergence from the 20th century average.

요약

• 해수면의 온도는 지속적으로 증가해왔으며, 2021년 전세계 해양 표면 온도는 평균 0.65 섭씨 상승하였음
• 연간 데이터에서 일부 차이를 제외하더라도 상승 추세는 여전히 존재
• 표면 근처 온도에 대한 글로벌 데이터는 선박, 부표 및 핼양 위성 측정에서 제공됨
• 변동은 전상적인 현상이지만 전체 지구 평균, 육지 및 해양 평균 온도는 기후변화로 인해 따뜻해지고 있는 것으로 파악됨
• 과학적 발견에 따르면 지구 온난화는 극한 기상 현상의 강도, 빈도, 공간적 범위 및 지속시간의 변화로 이어질 것으로 예상됨
