A detailed, long - term ocean temperature record derived from corals on Christmas Island in Kiribati and other islands in the tropical Pacific shows that the extreme warmth of recent El Niño events reflects not just the natural ocean - atmosphere cycle but a new factor: global warming caused by human activity.
So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.
In addition, global sea level can fluctuate due to climate patterns such as El Niños and La Niñas (the opposing phases of the El Niño Southern Oscillation, or ENSO) which influence ocean temperature and global precipitation patterns.
