Further, following your google hint, a few models popped up, e.g. this one that says in abstract: «A box model of the ocean - atmosphere - sea ice - land ice climate system is used to study a novel mechanism for self - sustained oscillations of the climate system on a time scale of 100,000 years, without external forcing.»

The fact that the climate system can vary internally without external forcing is no reason to suspect that it does not also respond to external forcings, such as the strong response to increasing greenhouse gas concentrations that has occurred in the latter half of the 20th century.

Once your baby is sitting up and moving about, the skull will continue to harden without any external force directing the head's growth into a symmetrical shape.

The researchers aren't exactly sure how the bats are able to do this, but suspect it occurs by some combination of tongue deformation and the ability of fluids like nectar to flow without external force in certain narrow spaces, a phenomenon known as capillary action.

Without any external force, opinion, medication, diagnostic, etc..

Not exact matches

One danger to the Christian revolt is that it will enter into alliance with forces whose aims and strategies are so foreign to its own that when the common Victory is won — if won it can be — the revolutionary church will be left with the sad reflection that it supplied the «Fourteen Points» which gave specious sanctity to an outrageous peace and that its fruits of victory are an external prosperity based on rotting foundations and debts which it can not collect without destroying its own life.

The Law of Entropy states (proves) that order goes from a higher state to a lower one (not from lower to higher as it would without an external / God force).

Within fractions of a second, the structure can snap from its mostly flat conformation to one that can grip a small object and hold it without constant external force.

This novel fluorescent label - free approach uses the lateral shifts in the position of the microbead substrate in pillar arrays, for quantifying the biomolecules, based on the change in surface forces and size, without the need of any external equipment.

Without self - understanding and social awareness, moral action will always be at the whim of external forces.

Without paying too much attention an external FPS counter itself, Blue Reflection seemed to run at a fairly solid 60 FPS - though there's every possibility this is hard - capped to your monitor's refresh rate due to forced VSYNC; so just keep that in mind.

You can also account for possible errors in the amplitudes of the external forcing and the model response by scaling the signal patterns to best match the observations without influencing the attribution from fingerprinting methods, and this provides a more robust framework for attributing signals than simply looking at the time history of global temperature in models and obs and seeing if they match up or not.

Some of them are optimal fingerprint detection studies (estimating the magnitude of fingerprints for different external forcing factors in observations, and determining how likely such patterns could have occurred in observations by chance, and how likely they could be confused with climate response to other influences, using a statistically optimal metric), some of them use simpler methods, such as comparisons between data and climate model simulations with and without greenhouse gas increases / anthropogenic forcing, and some are even based only on observations.

I never asserted that sensitivity in terms of equilibrium time - average surface temperature change per unit change in TOA or even tropopause - level forcing (with or without stratospheric adjustment) would be the same for each type of forcing for each climatic state and the external forcings that maintain it (or for that matter, for each of those different of forcings (TOA vs tropopause, etc.) with everything held constant.

For example they are using the measured CO2 as an external forcing, without considering that CO2 concentration is also the results of several carbon cycles natural mechanisms that might in part respond to solar variation too.

Extremely likely: Warming during the past half century can not be explained without external radiative forcing.

On a 2006 Royal Society web page Carl Wunsch explains how random climatic processes can alter global temperature without any changes in external forcing: http://royalsociety.org/News.aspx?id=5319

re # 3, without accurate forcing data, it is difficult to rule out other modes of external forcing and also natural internal modes of variability.

Not to mention abrupt climate change, which has been documented in the past to occur without any obvious external forcing.

The results from CMIP confirm what was noted in the SAR in that the basic patterns of climate system response to external forcing are relatively robust in models with and without flux adjustment (Gregory and Mitchell, 1997; Fanning and Weaver, 1997; Meehl et al., 2000a).

The consequence is that in the natural world all oscillatory behavior is damped, and without an external driver the oscillations would die out — it is unlikely that these processes began in 1880, so why are they still there without forcing?

Free extratropical Rossby waves with zonal wave numbers about 6 to 8 mostly occur as high - amplitude, fast traveling waves (the so - called synoptic transients responsible for much of the weather variability in the extratropics); once established, they can freely propagate predominantly to the east with a phase speed c ≈ 6 − 12 m ⋅ s − 1 without maintenance from external forcing.

Quoting (or parroting) the IPCC, EPA argues that it is «extremely unlikely» (less than a 5 % probability) that the warmth of recent decades can be explained without «external forcing» by greenhouse gas emissions.

In fact, in AR4 (Table 9.4), the IPCC lists five lines of evidence supporting the conclusion that «Warming during the past half century can not be explained without external radiative forcing».

When assessing changes in ENSO, it must be recognised that an El Niño - like pattern can apparently occur at a variety of time - scales ranging from interannual to inter-decadal (Zhang et al., 1997), either without any change in forcing or as a response to external forcings such as increased CO2 (Meehl and Washington, 1996; Knutson and Manabe, 1998; Noda et al., 1999a, b; Boer et al., 2000b; Meehl et al., 2000b).
