For this, scientists rely on proxies — traces of climate's imprint contained in sediment collected from ocean beds or from the shells of creatures that lived back then.

It is different from previous studies that use climate proxies because it uses a brand new temperature reconstruction for the tropical oceans.

Second, the quantity of methane necessary to explain the carbon isotope ratio, as calculated by Dickens, would be much less than that required to warm ocean and atmosphere temperatures to the extent estimated by PETM temperature proxies and calculated by physical climate models.

Climate reconstructions based on borehole and ocean sediments (Moburg) are lower over the past few hundred years than reconstructions based on surface proxys.

As noted in that post, RealClimate defines the Atlantic Multidecadal Oscillation («AMO») as, «A multidecadal (50 - 80 year timescale) pattern of North Atlantic ocean - atmosphere variability whose existence has been argued for based on statistical analyses of observational and proxy climate data, and coupled Atmosphere - Ocean General Circulation Model («AOGCM») simulatocean - atmosphere variability whose existence has been argued for based on statistical analyses of observational and proxy climate data, and coupled Atmosphere - Ocean General Circulation Model («AOGCM») simulatOcean General Circulation Model («AOGCM») simulations.

Ocean heat content increases (and the closely related sea level rise) is a far better long - term proxy for energy in the climate system.

1) It is such a smal part of Earth's energy system 2) It has such a low thermal inertia 3) It is so easily influenced by ocean cycles (i.e. the troposphere is the tail being wagged by the dog) 4) It is a poor metric (really a poor proxy) for climate sensitivity to GH gas forcing because energy quickly takes so many other forms in the system

I would suggest that a new proxy for heat being stored (or lost) from the Earth climate system be developed based on Total System Enthalpy, using a combination of moist enthalpy in the troposphere (after Pielke Sr.), ocean heat content, and total ice mass on the planet.

The results also highlight coastal regions that are well - represented in current generation climate models (and those that are not) and the time periods over which coastal sea level may be used as a proxy for the large - scale ocean circulation.

Our proxy records are compared with climate model simulations using a coupled atmosphere - ocean general circulation model.

Studies involving 28 million weather balloons, thousands of satellite recordings, 3,000 ocean buoys, temperature recordings from 50 sites in the US and a 1,000 years of temperature proxies suggest that the Global Climate Models overestimate positive feedback and are based on poor assumptions.

The hiatus is a flee that has ridden on the tale of the ocean, but certain people have chosen that flee to be a good proxy for full climate sentivity.

Yes, an island would make a terrible proxy for global climate, their weather being influenced and moderated, as they are, by oceans.

There are now several alternative proxy measures of ancient climate change, but the δ18O data (figure 1a) of Zachos et al. [4], a conglomerate of the global ocean sediment cores, is well suited for our purpose as it covers the Cenozoic era with good temporal resolution.

Because of the singularly rich climate story in Cenozoic deep ocean δ18O (figure 1), unrivalled in detail and self - consistency by alternative climate proxies, we use deep ocean δ18O to provide the fine structure of Cenozoic temperature change.

We prefer this result since it was based on a comprehensive analysis using extensive proxy data from both land and ocean in combination with an ensemble of climate model simulations, in a paper focused entirely on LGM cooling.

Additionally, tree rings, ocean and rock sediment also serve as proxy records of climate conditions of the past.

I was teased by my climate modeller colleagues about so much hands - on work with climate proxies (e.g., tree rings and ocean sediment cores) and was considered askance by my climate proxy colleagues.

Almost all climatologists work within a narrow slice of the total climatology pie: solar variations, the oceans, atmospheric circulation, heat transfer, cloud formation, proxies for past variability, climate models,... but very few if any, have a synoptic view of the entire field.

The reason why a 1 / S ^ 2 prior is noninformative is that estimates of climate sensitivity depend on comparing changes in temperature with changes in -LCB- forcing minus the Earth's net radiative balance (or its proxy, ocean heat uptake)-RCB-.
