Sentences with phrase «negative ocean cycle»

The problem for that idea is that even if it is possible the reduced energy flow from ocean to air merely mimics on a miniscule scale what happens naturally when a negative ocean cycle reduces the flow of energy from ocean to air.

A self stabilising system which is as well capable of neutralising any ocean skin effect as it is capable of neutralising negative ocean cycles, positive ocean cycles and any warming of the air by any increase in greenhouse gases.

Not exact matches

When we say «positive» and «negative» feedbacks in the sense of radiation (so I'm not talking about carbon - cycle responses such as methane release from the oceans or such) we're referring to temperature - sensitive variables which themselves affect the radiation budget of the planet.

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.

We could get rid of the negative forcings by subtracting the impacts of ocean cycles etc. from the temperature record, leaving only the anthropogenic component.

None of the Annan / Hargreaves priors go below zero, and while this may be physically realistic it does not allow for the fact that the observational data generate negative sensitivities, mostly because of ocean cycle warming and cooling effects that the radiative forcing estimates do not take into account.

It was mostly if not entirely a result of a change from a warm to a cold PDO cycle in 1939 (with a later assist from the AMO), and I get my negative sensitivities because the forcing estimates don't allow for the heating and cooling impacts of ocean cycles.

The problem with that argument is that over long periods of time (like the six decades since 1950), positive and negative phases of ocean cycles tend to cancel each other out, and thus internal variability doesn't have a large influence on long - term temperatures.

I would say that that was because cycle 19 was preceded and followed by weaker cycles and accompanied by a negative ocean phase.
