But as cogently interpreted by the physicist and climate expert Dr. Joseph Romm of the liberal Center for American Progress, «Latif has NOT predicted a cooling trend — or a «decades - long deep freeze» — but rather a short - time span where human - caused warming might be partly offset by ocean cycles, staying at current record levels, but then followed by «accelerated» warming where you catch up to the long - term human - caused trend.
Most scientists attribute this «pause» in warming to natural climate cycles that have a cooling effect on the planet, especially ocean oscillation cycles.

There are two main explanations for the 1940s to 1970s global temperature stagnation (or slight cooling): aerosol forcing and the negative phase of an ocean cycle known as the Atlantic Multi-decadal Oscillation (AMO), with the former contributing more than the latter.
Many people have postulated that there are cyclical changes in heat transfer from the oceans to the atmosphere which causes rhythmic cycles of warming / cooling.
The aim of the C - SIDE working group is to reconstruct changes in sea - ice extent in the Southern Ocean for the past 130,000 years, reconstruct how sea - ice cover responded to global cooling as the Earth entered a glacial cycle, and to better understand how sea - ice cover may have influenced nutrient cycling, ocean productivity, air - sea gas exchange, and circulation dynaOcean for the past 130,000 years, reconstruct how sea - ice cover responded to global cooling as the Earth entered a glacial cycle, and to better understand how sea - ice cover may have influenced nutrient cycling, ocean productivity, air - sea gas exchange, and circulation dynaocean productivity, air - sea gas exchange, and circulation dynamics.
Scientists studying oceans demonstrate that the recent warming, to the end of the last century, is part of the natural cycle of oceanic oscillations and predict a thirty year cooling phase.
But as a cooling world is now much more likely than a warming one for the next half century in the light of the current sunspot cycles and the ocean oscillations it would seem absolutely negligent to ignore the possibility, however politically incorrect it might be to entertain the thought.
Now stories will read for the new report, «IPCC blames warming hiatus on cooling from ocean cycles, but says ocean cycles have nothing to do with earlier warming».
The basic ocean cycle goes like this; in the summer brine is concentrated by evaporation and in the winter the dense brine cools and becomes still denser and sinks.
