For example, if tribes migrate (d) to a certain locale or are forced out of an ideal way of life due to cataclysm etc, (such as leaving fruit bearing tropical climates due to sea level rise in ancient prehistory as seen from underwater megalithic stone temples from around the world) then that does nt mean their way of life currently is the most ideal that the body thrives on, such as «paleo» diet or atkins diet or other FAD BULLSHIT low carb, high fat diets that are EXTREMELY HARMFUL AS CITED CONCLUSIVELY.
The graphics are a bit Windows 2000, but the idea is neat: it controls the climate system or other parts of the set - up (automatic headlights, unlocking regime and so on), activates a trip computer, triggers a g - force meter or opens a bar - graph history of your efforts at driving economically.
Now the Robert Rauschenberg Foundation, which he set up to provide support for causes that were important to him, is joining forces with two other like - minded organizations to present a series of exhibitions, panel discussions and performances that will explore climate change.
To better understand what Kilimanjaro and other tropical glaciers are telling us about climate change, one ultimately ought to drive a set of tropical glacier models with GCM simulations conducted with and without anthropogenic forcing (greenhouse gases and sulfate aerosol).
The absence of convincing attribution of periods other than 1976 - present to anthropogenic forcing leaves natural climate variability as the cause — some combination of solar (including solar indirect effects), uncertain volcanic forcing, natural internal (intrinsic variability) and possible unknown unknowns.
Some other forcings have a very small global radiative forcing and yet lead to large impacts (orbital changes for instance) through components of the climate that aren't included in the default set - up.
The other point is that attribution studies evaluate the extent to which patterns of model response to external forcing (i.e., fingerprints) simulations explain climate change in * observations.
While the local, seasonal climate forcing by the Milankovitch cycles is large (of the order 30 W / m2), the net forcing provided by Milankovitch is close to zero in the global mean, requiring other radiative terms (like albedo or greenhouse gas anomalies) to force global - mean temperature change.
In general, I heartily agree — other forcings are important, even essential, for understanding observed climate variability and, as a community, we are only just starting to get to grips with some of the more complicated effects.
The assessment based on these results typically takes into account the number of studies, the extent to which there is consensus among studies on the significance of detection results, the extent to which there is consensus on the consistency between the observed change and the change expected from forcing, the degree of consistency with other types of evidence, the extent to which known uncertainties are accounted for in and between studies, and whether there might be other physically plausible explanations for the given climate change.

The problem here is that the «forcings» are in fact some other inherent variables of the very same climate - bearing system, but there is no clear separation of time scales that allow for any sort of coherent theories like «averaging of fast motion» that results in Landau - Ginzburg - type equations for «slow envelopes».
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.
What we will learn is that human emitted carbon is merely «a drop in the pond» and that other factors which the «enthusiasts» have conveniently dismissed and the IPCC and other models have ignored are the real drivers and forcing of climate over both the long and short terms.
In other words, it is possible that the the climate system does exhibit some kind of long - term chaos in some circumstances, but that the forcing is strong enough to wipe out any significant uncertainty due to initial conditions — at least if one is content to forecast statistical quantities such as, for example, decadal mean January temperatures in some suitably large region, or perhaps temperature variances or quartiles taken over a similar period.
