Sentences with phrase «about ocean cycles»

One of the key drivers of tropospheric temperatures is sensible and latent heat flux from the largest climate energy source on the planet - the ocean — thus, the so - call hiatus tells us more about ocean cycles (ENSO & PDO) than about climate sensitivity to increasing GHG's.

No, they were just talking about ocean cycles.

A new study led by The Australian National University (ANU) has found seawater cycles throughout Earth's interior down to 2,900 km, much deeper than previously thought, reopening questions about how the atmosphere and oceans formed.

Researchers have known for years that diatoms can remove iron from oceans and carbon from the atmosphere, but little is known about how iron is cycled and removed from the Antarctic region.

About 19 months after the wind churned the ocean, cycling warm deep waters upward and sending the cold surface waters down, the Totten ice shelf was noticeably thinner and had sped up.

Age is critical because it takes about 200 million years for oxygen isotopes in the seas and crustal rocks to be homogenised by cycling through thermal vents in the ocean floor.

A new study shows that nitrogen - feeding organisms exist all over the deep ocean, and not just in large oxygen - depleted «dead zones,» changing the way we think about the delicate nitrogen cycle.

About 104 stages of these cold and temperate cycles have been recognised in deep ocean marine sediment cores (Figure 1)[1].

About BIOACID: Since 2009, more than 250 BIOACID scientists from 20 German research institutes have investigated how different marine organisms respond to ocean acidification and increasing carbon dioxide concentrations in seawater, how their performance is affected during their various life stages, how these reactions impact marine food webs and elemental cycles and whether they can be mitigated by evolutionary adaptation.

So there are cycles, possibly related to ocean conditions in the Pacific, which can bring about super-droughts even without fossil fuelled carbon in the atmosphere.

I'm not just talking about 2008 being a La Nina year, I'm talking about the last 5 years that the oceans in particular have been cooling, long before the end of the last solar cycle or the recent La Nina.

I wonder, given the recent news about the various ways plankton actively affect the oceans, including churning the upper 100 meters, if any of the cycles could reflect big changes in which species predominate over time.

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.

Based on findings related to oceanic acidity levels during the PETM and on calculations about the cycling of carbon among the oceans, air, plants and soil, Dickens and co-authors Richard Zeebe of the University of Hawaii and James Zachos of the University of California - Santa Cruz determined that the level of carbon dioxide in the atmosphere increased by about 70 percent during the PETM.

As to the bottom line, we are talking about changes to a fundamental part of the ocean carbon cycle, far outside the range of natural variability, that are irreversible and will last for thousands of years.

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.

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).

-- Co2 released to the atmosphere through the burning of fossil fuels is cycled through the oceans based on a five year residence time, so that only about a quarter of the co2 in the atmosphere at any one time is from man.

A lot to be learned about the carbon cycle on both ocean and land.

Over very long time periods such that the carbon cycle is in equilibrium with the climate, one gets a sensitivity to global temperature of about 20 ppm CO2 / deg C, or 75 ppb CH4 / deg C. On shorter timescales, the sensitivity for CO2 must be less (since there is no time for the deep ocean to come into balance), and variations over the last 1000 years or so (which are less than 10 ppm), indicate that even if Moberg is correct, the maximum sensitivity is around 15 ppm CO2 / deg C. CH4 reacts faster, but even for short term excursions (such as the 8.2 kyr event) has a similar sensitivity.

The combined effects of oceans and vegetation are known from ice cores: dCO2 / dT is about 8 ppmv / °C, pretty constant over 4 ice age — interglacial cycles in 420,000 years and surprisingly linear, despite that a number of players in this game are acting far from linear.

He said he played plenty for his tuition but in two courses supposedly covering climate, he had not heard anything about the factors like multidecadal ocean cycles and the various ways cycles on the sun affect climate only greenhouse gases.

The oscillation of about 0.5 deg C about every 30 years is due to ocean cycles as described in the following paper:

VP: «The literature tends to be vague about the periods of ocean oscillations, which I suspect is because it's hard to separate the 50 - year and 75 - year cycles.

The global surface temperature increase since about 1860 corresponds to a recovery from the Little Ice Age, modulated by natural ocean and atmosphere cycles, without need for additional forcing by greenhouse gases.

The same thing about measuring two cats and finding the same weight can be said of recent warming caused by rise in CO2 and rise of CO2 happening to be coincident with warming caused by a natural ocean cycle (AMDO).

The observation of a historically high level of TSI from 1961 to 2001 tends to fit with the theories set out in my other articles about the real cause of recent warming and the real link between solar energy, ocean cycles and global temperatures.

Personally I think that recent research (including several studies discussed in the above post, published after the IPCC AR5 cutoff date) make a strong case that internal variability (ocean cycles) are responsible for more of the slowdown in surface warming than changes in external forcings, but there's not a consensus about that yet.

What about an internal cycle, perhaps from volcanoes or the ocean, that releases massive amounts of greenhouse gases?

IPCC Scientist Warns UN: We are about to enter «one or even 2 decades during which temps cool» — Admits «Jury is still out» on ocean cycle's temp impact!)

IPCC Scientist Warns UN: We are about to enter «one or even 2 decades during which temps cool» — Admits «Jury is still out» on ocean cycle's temp impact!

Natural earth / ocean climate cycles like PDO, AMO, NAO and ENSO are not even talked about by these same alarmists.

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

If I were to speculate about additional natural factors; such as THC / MOC, or some assumed millennial ocean cycle, or some third unknown factor that impacts ENSO and the PDO, or some initiator of ENSO events; that speculation would detract from my work, not add to it.

Dessler finds that the short - term changes in surface temperature are related to exchanges of heat to and from the ocean - which tallies well with what we know about El Niño and La Niña, and their atmospheric warming / cooling cycles.

In comparison cycle 23 only went down about 0.16 °C, not as strong as cycle 17 but enough to almost exactly cancel the CO2 - induced warming, while the ocean oscillations stayed out of the picture as noted above.

Now forced to explain the warming hiatus, Trenberth has flipped flopped about the PDO's importance writing «One of the things emerging from several lines is that the IPCC has not paid enough attention to natural variability, on several time scales,» «especially El Niños and La Niñas, the Pacific Ocean phenomena that are not yet captured by climate models, and the longer term Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) which have cycle lengths of about 60 years.»

If and when you can provide data or references to document your claims, or if you were to point me to those data or references — data and references that would help illustrate and document my posts, (which are about the multiyear aftereffects of ENSO events on global SST and TLT anomalies, and about the discharge / recharge aspects of ENSO, and about the impacts of ENSO, NAO, NPI, AMO on OHC, not the PDO, not what initiates ENSO events, not millennial ocean cycles, etc.)-- I would be happy to include it.

«Carbon models» may «indicate that the ocean will be a net sink for CO2» (as you write), but, inasmuch as the natural carbon cycle is so much greater than the human emissions, we are talking about a small difference between large numbers.
