«In order to predict how ecosystems will react when you heat up the planet or acidify the ocean, we first need to understand the mechanisms of everyday carbon cycling — who's involved and how are they doing it?»

Regional trends are notoriously problematic for models, and seems more likely to me that the underprediction of European warming has to do with either the modeled ocean temperature pattern, the modelled atmospheric response to this pattern, or some problem related to the local hydrological cycle and boundary layer moisture dynamics.

How does the enormous diversity of zooplankton species, life cycles, size, feeding ecology, and physiology affect their role in ocean food webs and cycling of carbon?

How do these changes impact the biogeochemical cycles in the oceans?

Other big differences are removing AQUA and NOAA - 15, which appeared to have an evolving bias based on comparisons to other satellites, especially over oceans where we don't expect diurnal cycle problems to be big.

Each day offers something new and exciting to do, with guided expeditions and treks in the ocean, on the beach, around the town, and deep into the tropical jungle, learn about and explore the island while cycling, snorkeling, horse - back riding, kayaking, hiking and driving dune - buggies.

Create your own cycling loop or do a car shuttle with friends following the many roads and 4WD tracks throughout the Otway National Park, steep climbs to the top of the range with exciting down - hill runs back to the Great Ocean Road.

Does the onset of ocean anoxia at the end of many of these events suggest a possibility of cycle where the collapse of one civilization provides the seeds (fossil fuels) for the next?

Proposed explanations for the discrepancy include ocean — atmosphere coupling that is too weak in models, insufficient energy cascades from smaller to larger spatial and temporal scales, or that global climate models do not consider slow climate feedbacks related to the carbon cycle or interactions between ice sheets and climate.

You do know the oceans release heat daily, weekly, seasonally, and in various oscillations and cycles, etc..

One does not have to worry about instabilities associated with ice sheets, feedback from the carbon cycle (even though this would seem to already be coming into play), or instabilities associated with ocean circulation.

It is not a minor point, because we don't expect such perfect cycles in sloppy geophysical systems like oceans.

The model may be right over the full 131 year period, but in this case doesn't reflect natural cycles including El Nino and longer cycles (as is the case for ocean warming, where models — significantly — don't reflect any cycle with a length between 10 - 100 years).

In a reconstruction of Pacific Ocean temperatures in the last 10,000 years, researchers have found that its middle depths have warmed 15 times faster in the last 60 years than they did during apparent natural warming cycles in the previous 10,000.

There are several feedbacks between decreasing the rate of calcification that organisms do in the ocean, and the carbon cycle.

For BNO (S) alone in its last quarter cycle 2000 - 14 (for which we have the best data OHC) the ΔOHC 0 - 2000m record is 4x larger and of opposite sign (contradicting the assumption of BNO = AGW by suggesting AGW is 5x bigger in magnitude than BNO (S) for this period if BNO (S) did exist using 0 - 2000m ocean storage).

SO just HOW can we justify that that the outflow in the computer MUST be less than inflow for the 250 years of the computer run, when clearly the daily temperature cycle will reestablish the equilibrium (at least for the atmosphere & ground — not sure about deep ocean equilibrium, BUT I also know that there is MUCH MUCH MORE energy stored in the Land (eg solid iron core of earth) than in the ocean & the GCMs do NOT address this either).

The available data are insufficient to say if the changes in O2 are caused by natural variability or are trends that are likely to persist in the future, but they do indicate that large - scale changes in ocean physics influence natural biogeochemical cycles, and thus the cycles of O2 and CO2 are likely to undergo changes if ocean circulation changes persist in the future.

As for the Sun, well, like AnnaV I consider that the 2 by far most important factors in climate evolution is the cloudiness because it governs albedo and the large scale oceans» behaviour because that's where the energy is Again you are so angry at the AGW crowd, that you miss the whole point: the all - important clouds and albedo vary together, but do not vary with the solar cycle, as far as our observations go, e.g. http://www.leif.org/research/cloud-cover.png and http://www.leif.org/research/albedo.png

For instance, perfect initialization of the state of the Atlantic ocean, a correct simulation of the next 10 years of the solar cycle, a proper inclusion of stratospheric water vapor, etc may be important for whether the next 5 years are warmer than the previous 5, but it has nothing to do with climate sensitivity, water vapor feedback, or other issues.

When we do, no matter how good the climate model is it will not be able to overcome deficiencies in our ability to predict the things that affect climate — solar activity, ocean cycles, etc — and it will not be able to overcome deficiencies in our understanding of how things that affect climate actually work — solar activity, Earth orbital changes, etc..

You don't have to doubt the catastrophic anthropogenic global warming theory to know that there are key variables that have important, measurable effects on world temperatures at these kind of timescales — ocean cycles come to mind immediately — which he has left out.

This leads Prof Curry to say the IPCC's models are «incomplete», because they do not adequately account for natural factors such as long - term ocean temperature cycles and a decline in solar output, which have suppressed the warming effects of CO2.

SAW is not composed of ocean cycles, and by the end of the poster there is no attempt to claim that it does..

According to you, Svalgaard should be able to calculate «the total excess energy which entered the oceans» and be «able to calculate cloud cover, both volume and latitude» for two sets of 4 solar cycle time frames that you don't even identify.

Additionally, these cycles simply move thermal energy between the ocean and the atmosphere, and do not change the energy balance of the Earth.

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».

Each major cycle took water out of the oceans and did not put all of it back in the oceans.

The cyclic nature of the oceans does not change, but the temperature range within the cycles does.

This robust cycle does not care if we cause any warming, the polar oceans thaw and increase the cooling snowfall at the same thermostat set point.

CO2 did come from oceans as they heated up at end of ice age cycles with significant contributions from eurasian swamps as well.

Variations in 20th century trends which do not correlate to c02 are routinely dismissed as either aerosols or heat going into the oceans, when it is very clear these are related to PDO cycles, which means climate sensitivity to c02 must be overstated.

And then get them to not only bring back into their fictional energy budget, KT97 and ilk, the Water Cycle, but to bring back the thermal infrared heat on the move from the Sun as the real world direct heat source for land and oceans, and, to give back to shortwave which they claim does this in place of thermal energy direct from the Sun, its real properties and properties, its chemical energy cycle, that store which slow releases heat back into the greenhouse atmosphere by recycling Cycle, but to bring back the thermal infrared heat on the move from the Sun as the real world direct heat source for land and oceans, and, to give back to shortwave which they claim does this in place of thermal energy direct from the Sun, its real properties and properties, its chemical energy cycle, that store which slow releases heat back into the greenhouse atmosphere by recycling cycle, that store which slow releases heat back into the greenhouse atmosphere by recycling Life.

The climate system has large thermal inertia (mostly from the oceans), and doesn't respond much to the «rapid» signal of an 11 year cycle.

You don't think perhaps that celestial cycles just might have an effect on magma currents (yes just like the ocean, just slower) and that effect translates to changes in sea - floor seismic activity from time to time?

Consider a possibility that the shifts / lags have less to do with the 11 - year solar cycle than they do with offset cycles of the ocean basins (see Tisdale).

I don't know whether these results are totally realistic, but they certainly look plausible, and they identify ocean cycles as the main source of regional temperature variations.

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.

But now the ocean cycles contributed three times as much to total 20th century global warming as did the sun (0.18 vs. 0.06 C).

Anyway, as I make the point here, The Greenhouse Effect is non-existant regardless of this mangling of real world physics, the comic cartoon of shortwave in and longwave out is stupid enough in claiming «that visible light heats ocean and lands and the heat direct from the Sun, thermal infrared, doesn't reach the Earth's surface and doesn't play any part in heating land and ocean», but, this warmist comic cartoon energy budget misses out the whole of the Water Cycle!

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.

A. Do not model the «earth» as a combined land / ocean / gas «thingy» (experiments 1 to 5) B. Do not model the atmosphere as a single body or layer (See experiment 4 & 5) C. Do not model the sun as a 1/4 power constant source without diurnal cycle (See experiment 5) D.

Do not model a moving atmosphere without Gravity (See experiment 4 & 5) G. Do not model the surface as a combined land / ocean «thingy» (See experiment 1)

I was thinking about how to include what little we do know about atmospheric and ocean cycles into the models.

Many scientists used to think that only periodic changes in earth's orbit — so - called Milankovitch cycles — could change climate, over thousands of years, but Broecker has shown that ocean currents can influence climate in mere decades — and could do so again.

Nice to finally have a rival theory, even if it is only «the sun did it and forget Henry's Law or the carbon cycle and that the ocean is acidifying anyway».

What do you think of Stockwell's evidence for a 1/4 cycle leading phase of solar cycle to ocean surface temperature?

As Dr. Curry noted, the paper does not cite evidence for the somewhat ambiguous statement in the press release that «Rapid warming in the last three decades of the 20th century, they found, was roughly half due to global warming and half to the natural Atlantic Ocean cycle that kept more heat near the surface.»

The previous and present models do project the possibility of a hiatus in warming, most commonly because increased wind shear over tropical oceans can transfer more energy into the oceans especialy during the La Nina phase of the ENSO cycle.

So if we attribute the ocean behaviour on a 60 year cycle to planetary movements doesn't that square the circle?
