They depend on the east - west oscillation of the tropical
Pacific thermocline, which adiabatically redistributes heat between the surface (~ 0 — 100 m)
and subsurface
ocean (~ 100 — 500 m)
and thus allows the near - surface
ocean to significantly alter its net heat exchange with the
atmosphere depending on the phase of ENSO [Roemmich
and Gilson, 2011].
An example of internal variability is El Niño, a warming cycle in the
Pacific Ocean which has a big impact on the global climate, resulting from the interaction between atmosphere and ocean in the tropical Pac

Global surface temperatures were the 8th or 9th highest recorded, partly because the first two months were cool - ish thanks to a La Nina in the
