Sentences with phrase «cyclic trends»

I suspect that under a pink assumption one might find it difficult to show that it is «very likely» that less than half the warming since 1970 is not due to random fluctuations on the assumption that all we have is linear trend plus noise, without having to bother with other natural cyclic trends.

The cyclic trends are projected forward and predict a probable general temperature decline in the coming decades and centuries.

There is also no hypothetical basis to presume that, even if it's a zero sum game, that there aren't cyclic trends with periods lasting centuries required to zero it.

Not from noise but from cyclic trends.

Note the sizeable departure of the data from the linear - plus - cyclic trend over the last several decades.

Professionals are trained to instruct using trends in data and implement a signature cyclic process of using student data to augment student achievement.

3) The overall accuracy at the global mean level is at least 2 % (one sigma) in the cloud amounts and thus none of the trends or apparent cyclic behaviour at the global mean level are significant.

You please look in to WMO (1966) mannual on «climate change» for the types analysis used to separate trend from cyclic variations which I did since early 1970s.

And his citing of the «WMO mannual on «climate change» for the types analysis used to separate trend from cyclic variations which I did since early 1970s» is not what he was citing it for in his December 2013 posting on Wattsupia.

(An example of a graph of a nonmonotonic function would be one showing cyclic behavior around an upward accelerating underlying trend curve.)

IPCC's 0.2 deg C / decade warming for the next two decades claim is wrong because the global mean temperature trend is cyclic as shown = > http://bit.ly/MkdC0k

The AMO is cyclic and will return to negative soon enough and this graph implies that sea ice trends will just reverse in a few years.

You've been fooled by chronic mathturbators — this is even more nonsensical than your «trend - plus - cyclic» model.]

But the task at hand was to test Dan H.'s claim that the Berkeley data reinforce the characterization of temperature change as «long - term linear trend» or «linear - plus - cyclic.»

The question you address at the end is to what extent the current «pause» is a temporary cyclic phenomenon and to what extent it is a true change in the long term trend.

If there are other non-linear effects that have a correlation to the independent variable (such as cyclic influences), the use of least - squares estimation of the trend is not valid.

These cyclic temperature trends give rise to an inevitable linkage to things we know for sure: Death and Taxes.

Climate change history is cyclic and the continuing downward trend of the Solar sunspot cycle follows previous patterns foretelling a cooling trend similar to a Dalton or Maunder Minimum.

Now in order to explain how a cyclic engine manages to produce semi-permanent step increases and / or secular trends in temperature, something about the engine is causing it to run in a larger enclosed area in either its P - V diagram (indicator diagram in the terminology of engines) or equivalently in its T - S diagram.

This shows how selectively restricting any analysis to only the most recent portion of the available data opens up the likelihood of confounding cyclic and non-cyclic trends leading to false diagnosis and attribution.

The amplitude of the cyclic component varies with the trend period.

It will take at least another quarter century of such a systemic program to determine whether this is a more or less continuing trend of greater melt or if such melts are of a regular cyclic pattern.

John Philips (13:43:35) «Trends» have become virtually meaningless lately, since the word has been so variably used, but try this: Eyeball the temperature curve as correlated to the Pacific Decadal Oscillation and you will see an excellent relationship with the cyclic cooling and warming phase of the PDO overlaid on a gradual warming trend emerging from the Little Ice Age.

There appears to be a 60 - 70 years cyclic warm / cooling trend and a zero order constant background (little ice - age bounce?).

[a] perceptually striking characteristic of fractional noises is that their sample functions exhibit an astonishing wealth of «features» of every kind, including trends and cyclic swings of various frequencies.

The cyclic solar effects are superposed on a long - term cooling trend.

THe UPWARD going linear warming trend (1850 - 2000) can not be explained with Scafetta, but the cyclic shape of the upward trend.....

However, it is instructive to note that a simple model of a linear trend plus sine wave matches history so well, particularly since it assumes such a small contribution from CO2 (yet matches history well) and since in prior IPCC reports, the IPCC and most modelers simply refused to include cyclic functions like AMO and PDO in their models.

Using your previous example of the cyclic nature of climate over time frames of hundreds of years (driven by Milankovich cycles, though several of us have had the impression you're unaware of it), we're not interested in time scales for which we have no * physical * basis for expecting a CO2 - forced trend.
