«Such decadal climate fluctuations are superimposed on the general warming trend, so that at times it seems as if the warming trend slowed or even stopped.

Combining the STORM model with analysis of the rainfall data set allowed the investigators to gain insights into decadal trends in monsoonal rainfall intensity under climate change.

Though the ecological effects of these climate oscillations have been described in various settings, the influence of decadal indices to long - term marine turtle population trends is largely unexplored.

[11] Few attribute the decline in fog, and moreover, climate change, to the Pacific Decadal Oscillation, however, as the Pacific Decadal Oscillation is an oscillation moving heat through the climate system but neither creating nor retaining heat, it is not a cause of warming trends or declines in fog.

Specifically, he addressed a claim made by Will Happer, a Princeton professor, that no models demonstrate decadal variability in trends (which was not the case), and explored in depth the signal to noise ratio in determining climate trends much more comprehensively than had been done previously.

Well when I look at it the GISS decadal, climate only, signal trend, matches the weather and climate decadal signal trend.

He says «Well when I look at it the GISS decadal, climate only, signal trend, matches the weather and climate decadal signal trend.

Additionally, the observed surface temperature changes over the past decade are within the range of model predictions (Figure 6) and decadal periods of flat temperatures during an overall long - term warming trend are predicted by climate models (Easterling & Wehner 2009).

Decadal nets are important for climate trends and sea level.

You may think these are unimportant at the decadal scale, but this is exactly the topic of Cohn and Lins paper, and, getting back on topic, the Tsonis paper — these larger scale variations have a huge impact on how we perceive climate in the 20th century, particularly in the interpretation of trends.

Even a perfect model can deviate significantly from past observed trends or changes, just because the physical system allows variability at decadal time scales; the climate and its trend that we're experiencing is just one of the many climates that we could have had.

However, this relationship (which, contrary to the claim of MFC09, is simulated by global climate models, e.g. Santer et al. [2001]-RRB- can not explain temperature trends on decadal and longer time scales.»

According to IPCC AR5, the mismatch between models and observations during both 1984 - 1998 and 1998 - 2012 may be due to «internal decadal climate variability, which sometimes enhances and sometimes counteracts the long - term externally forced trend» (Chapter 9, p. 769).

MIT Scientist's study finds: Data may be «insufficient to compute mean sea level trends» — Decadal Trends in Sea Level Patterns: 1993 - 2004 — By Dr. Carl Wunsch, MIT et al. in Journal of Climate — October 12, 2008

A 35 - year dust record established from Barbados surface dust and satellite observations from TOMS and the European geostationary meteorological satellite (Meteosat) show the importance of climate control and Sahel drought for interannual and decadal dust variability, with no overall trend yet documented (Chiapello et al., 2005).

Eg, even over a 30 - year period (statistically significant WRT climate change), the range of decadal trends starts at -0.05 C for the South pole, and is greatest at 0.45 C at the North pole.

Unforced variability of global temperature is great, as shown in Figure 4, but the global temperature trend on decadal and longer time scales is now determined by the larger human - made climate forcing.

Another paper in Climate Change in 2007 stated: Studies that have looked at hemispheric and global scales conclude that any urban - related trend is an order of magnitude smaller than decadal and longer time - scale trends evident in the series (e.g., Jones et al., 1990; Peterson et al., 1999)... Thus, the global land warming trend discussed is very unlikely to be influenced significantly by increasing urbanization (Parker, 2006).

Latif, M., Martin, T. & Park, W. Southern Ocean sector centennial climate variability and recent decadal trends.

Granted, the trend of this period is a mere 1 / 3rd of the IPCC prediction of 0.2 C / decade, but what this tells us is the presence of decadal trends might tell us almost nothing about the climate regime we are observing.

This is partly because the interannual to decadal variability is generally large in these variables, and partly because there are large uncertainties and sometimes an artificial trend in observations owing to the difficulty in measurement of these climate variables (Trenberth et al. 2007).

At this point it is possible to attempt a full forecast of the climate since 2000 that is made of the four detected decadal and multidecadal cycles plus the corrected anthropogenic warming effect trending.

A CDR suitable for studying interannual to decadal climate variability and trends includes a time series produced with stable, high - quality data, and error characteristics that have been quantified by accounting for all of the above sources of error and noise.

These errors, as well as the influence of decadal and multi-decadal variability in the climate, have been taken into account when estimating linear trends and their uncertainties (see Appendix 3.

Analyses of satellite - derived phytoplankton concentration (available since 1979) have suggested decadal - scale fluctuations linked to climate forcing, but the length of this record is insufficient to resolve longer - term trends.
