Not exact matches

Scientists can measure how much energy greenhouse gases now add (roughly three watts per square meter), but what eludes precise definition is how much other factors — the response of clouds to warming, the cooling role of aerosols, the heat and gas absorbed by oceans, human transformation of the landscape, even the natural variability of solar strength — diminish or strengthen that effect.

Global climate models need to account for what Meehl calls «slowly varying systems» — how warmer air gradually heats the ocean, for example, and what effect this warming ocean then has on the air.

«Ultimately, we want to know what effect the transportation and storage of heat has on the ocean.

So, for example, a big part of what drives a hurricane is the fact that you've got a lot of warm water near the surface of the ocean that is transferring heat into the air, and that's what's moving up, and that is a big part of then what's propelling the entire bigger storm system.

Ocean levels are increasing mostly because of what heat does to water, in all its various states.

«What was different about how heat and carbon were moving around in the ocean?»

What scientists discovered in 2014 is that since the turn of the century, oceans have been absorbing more of global warming's heat and energy than would normally be expected, helping to slow rates of warming on land.

This warm air layer gets its heat reflected downwards during cloudy periods, especially during long night extensive cloudy periods, as a result, Arctic ocean ice doesn't thicken so much during darkness and leaves it up to summer sunlight (if there is some) to finish off what is left of it.

All of that heat in the oceans also raised global sea levels to a new record high, more than 2.5 inches above what it was in 1993, as water expands as it heats up.

As oceans contain around 80 % of the climate's total energy, ocean heat is a good measure of what's happening with our climate.

Some organization or groups of organizations likely with the National Oceanic Administration leading should come up with the mid Atlantic volcanic rift heat output totals for correlation with the ocean currents to have a real time indication of where the heat is going and what and where the temperature increases are located.

What's the best estimate of the amount of heat the oceans have absorbed?

Natural variability is primarily controlled by exchange of heat between the ocean and the atmosphere, but it is an extremely complex process and if we want to develop better near - term predictive skills — which is looking not at what's going to happen in the next three months but what's going to happen between the next year and 10 years or 20 years or so — if we want to expand our understanding there, we have to understand natural variability better than we do today.

The team would also like to discover at what point a liquid water ocean forms; whether it forms almost immediately or if it requires a significant buildup of heat first.

This type of warming can not be produced by the ocean circulation, which to a first approximation just moves heat around on the planet — what it robs from Peter it gives to Paul.

The way the ocean transported heat, nutrients and carbon dioxide at the peak of the last ice age is significantly different than what has previously been suggested.

I just got back from Florida and what really made my trip (besides the gorgeous sunshine, ocean water and tropical heat), was this cute little dress that I took along.

If the waves of the Atlantic Ocean keep you at bay, then our oceanfront heated pool may be just what you need.

What prevents most of that from evaporating water instead of heating the deeps of the oceans?

This warm air layer gets its heat reflected downwards during cloudy periods, especially during long night extensive cloudy periods, as a result, Arctic ocean ice doesn't thicken so much during darkness and leaves it up to summer sunlight (if there is some) to finish off what is left of it.

What is implicit, I think, in all this «wait for the models» talk is that there is no model for the ocean heat to contact so much ice in just eighty years.

Can anybody refer to a paper that clearly describes to what extent the ENSO variability actually relates to changes in the total thermal energy of the system (oceans + air), and to what extent it's just heat being shuffled around within the system from one place to another?

What the ice actually does in a particular year depends upon the «forcings» (to misapply a term, perhaps) actually occurring — net ocean heat fluxes, net radiative fluxes, winds and currents (especially, but not exclusively, as they determine ice export to the North Atlantic.)

What is different now that causes the ocean to take up proportionately more heat than then?»

Think of what would happen if you could pump cold deep water up to the surface, increasing the air / sea temperature gradient and warming the water; that would give you an anomalously large ocean heat uptake.

As for how heat transfers to the ocean: I'm just a musician, but what's the role of La Nina in this?

There is still debate over what kind of ocean circulation change causes the change in heat transport.

... not intended to suggest that the heat capacity exchange / transfer / transport rates used are a realistic representation of actual ocean circulation, although from what little I know, it could be a step in that general direction from using one upper and one deep ocean reservoir.

THAT's what's being proposed when scientists say they think the heat that is not warming the atmosphere as quickly is instead warming the oceans.

(More specifically, you've read it as supporting a * lag * in response, without considering that perhaps (given the physics of a high mass / high specific heat system like the oceans) what is really implied is, rather, a slow * rate * of response — but one which nevertheless «starts» immediately.)

What I mean by this is: When you plot ocean heat uptake against climate sensitivity, I get the impression that the distribution of good models will be a large clump around a climate sensitivity of 3 but then there is a long tail out towards higher sensitivities.

The problems with associating sensitivity with a temperature in 2100 are twofold: first, at the time we reach CO2 doubling, the temperature will lag behind the equilibrium value due to thermal inertia, especially in the ocean (thought experiment — doubling CO2 today will not cause an instant 3C jump in temperatures, any more than turning your oven on heats it instantly to 450F), and secondly, the CO2 level we are at in 2100 depends on what we do between now and then anyway, and it may more than double, or not.

The heat going into the ocean is not going to be «released to the atmosphere» any time soon — it is instead part of what will be the higher OHC in a warmer world.

that some level of statistical significance can be achieved for periods shorter than 30 years, but not 15 years because fluctuations in things like solar + ocean - atmosphere heat exchange make it hard to say with high confidence what's signal and what's noise.

What I am looking for is a properly argued discussion that proves that a process that «hides» the heat in the deep oceans, (or anywhere else for that matter) exists.

The problem is that for most purposes (fluxes of heat into the oceans, and hence ocean warming and hence sea level rise; or biosphere responses) what you care about * is * the surface temperature.

We're essentially running a large experiment where we're putting this heat into the deep ocean and we don't quite know what the downstream effects are going to be.

For hurricanes, then, you'd want to ask what the sea surface temperature, subsurface ocean heat content, and atmospheric water vapor content would have been if, say, fossil fuel use had been eliminated 100 years ago, and atmospheric CO2 remained at about 300 ppm.

The slight drop in net ocean heat from 2003 - 2005 fits what the Astrophysicists predicted some years ago.

Another 0.5 K of warming is already «in the pipeline» due to ocean heat storage no matter what we do.

On a larger point, the radiative imbalance in the AR4 models is a function of how effectively the oceans sequester heat (more mixing down implies a greater imbalance) as well as what the forcings are.

If a significant fraction of this heat lost from the ocean went into the atmosphere one might have expected the surface air temperature to have increased faster during this period than during the subsequent period of the 1990s when the ocean heat content gained > 5 X 10 ^ 22 J, but this is not what was observed (see reference Figure 2.7 c in the IPCC TAR Working group I).

How and at what point do the oceans come into heat balance?

Computer simulations of the atmosphere and ocean, when run with rising greenhouse gases, show the warm pool heating at the same rate as other ocean regions, in contrast to what has been observed there so far, the researchers said.

What keeps the hurricane going is the cold upper atmosphere and the warm sea surface (and a warm mixed layer of the upper ocean will sustain the hurricane)-- just like a Carnot heat engine.

Of course, maybe this is kind of what you were saying all along:), but it worried me when you said that the air could gain heat from the water and still cool, which is only possible if the air is radiating heat to space faster than it is receiving it from the ocean.

Consider the possibility that not just millions, but billions face disastrous consequences from the likes of (including but not limited to): Sandy (and other hybrid and out - of - season storms enhanced by the earth's circulatory eccentricities and warmer oceans); the drought in progress; wildfires; floods (just last week, Argentina had 16 inches of rain in 2 hours *); derechos; increased cold and snow in the north as the Arctic melts and cracks up, breaking up the Arctic circulation and sending cold out of what was previously largely a contained system, and losing its own consistent cold, seriously interfering with the Jet Stream, pollution of multiple kinds such as in China, the increase of algae and the like in our oceans as they heat, and food and water shortages.
