Holgate (2007) showed decadal rates of sea - level rise (linear trends over 10 years), but as we have shown in Rahmstorf et al. (2012), those vary wildly over time simply as a result of sampling noise and are not consistent across different data sets (see Fig. 2 of our paper).

I just give you data that shows, on the backcast, the models, surprisingly, hit all the decadal trends since 1950 in a signal it was supposedly not tuned to match.

At longer (decadal) time scales, the models still show very similar results (which makes sense since we anticipate that the tropical atmospheric physics involved in the trend should be similar to the physics involved at the monthly and interannual timescales).

While that is possible, the so - called Pacific Decadal Oscillation (PDO) index that is used to characterize decadal and multi-decadal variability of the Pacific Ocean has not shown a significant increasing or decreasing three - decade trend from the 1980's to the 2000's (it's dominated by quasi-decadal fluctuation sinceDecadal Oscillation (PDO) index that is used to characterize decadal and multi-decadal variability of the Pacific Ocean has not shown a significant increasing or decreasing three - decade trend from the 1980's to the 2000's (it's dominated by quasi-decadal fluctuation sincedecadal and multi-decadal variability of the Pacific Ocean has not shown a significant increasing or decreasing three - decade trend from the 1980's to the 2000's (it's dominated by quasi-decadal fluctuation sincedecadal variability of the Pacific Ocean has not shown a significant increasing or decreasing three - decade trend from the 1980's to the 2000's (it's dominated by quasi-decadal fluctuation sincedecadal fluctuation since 1980).

In some models, the decadal variability for monsoons such as the South Asian monsoon also outweighs the magnitude of the future trends, and in others it does not (the review above is one example showing this).

For example the increasing trend in the coherent NHSM decadal precipitation shown in the paper (Figure S3B: the spatial pattern and associated principal component time series of the EOF) in fact suggest a weakening over recent decades in much of India and East Asia.

On longer time scales, the two longest time series (using independent criteria for selection, quality control, interpolation and analysis of similar data sets) show good agreement about long - term trends and also on decadal time scales.

James Risbey and I published a paper last Sunday with colleagues that used a set of maps in one of the figures to show the modeled and observed decadal trends (Kelvin / decade) of Sea Surface Temperature (SST).

Both the decadal trends and the shift in the date of minimum show distinctly non linear variability.

Yet then after that you say, with apparent complete confidence, that on a (multi)- decadal scale instrumental records show a positive trend.

Climatologies of Rocky Mountain snowpack are shown to be seasonally and regionally complex, with Pacific decadal variability positively reinforcing the anthropogenic warming trend.

One can arbitrarily select short term (e.g., decadal) intervals to show trends in various directions, but based on the history of the past century, they have little value in evaluating the longer term trends.

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).

Anthony Watts posted: NCDC data shows that the contiguous USA has not warmed in the past decade, summers are cooler, winters are getting colder Burt Rutan sent Watts «Winter Trends in the United States in the Last Decade» showing the winter decadal trend from 2001/02 to 2011/10.

The period 1993 - 2003 showed +2.5 mm / year rise over this period (IPCC AR4 reported +3.1 mm / year, but concedes that it is unclear whether this faster rate «reflects decadal variability or an increase in the longer - term trend»).

If the sea ice around Antarctica is growing (on a decadal trend basis)-- which any schoolboy analysis of freely available basic data shows...... what does this tell you about the certainty of global warming?

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.

Different approaches show very similar long - term trends, but noticeably different interannual and decadal - scale variability.

And yet we have observations that show large variability against a small trend and decadal shifts in trajectory.

Comparing the last two decadal trends shown above, what is your conclusion regarding the warming rates?

37) would show a positive trend over the previous 40 yr in a regression analysis, even though the main feature was a single decadal warming episode in the 1980s that was followed by cool anomalies.»

My results shown in the table in the first link below agree well with those in Marvel using the run averages, but the individual runs in my decadal analysis are similar to those were I used yearly regression and show large trend differences with some forcing categories having very wide CI ranges.

O.K. Give me a page reference where a statistical test has been performed that shows that the recent decadal trend has a slope that is statistically significantly different to the 30 year trend.

If skeptics attempted to state the global average temperature of the LIA or MWP within tenths of a degree, and published trends purporting to show temperatures with such precision over decadal and century time periods, then it would be inconsistent with criticisms of the claims of the consensus regarding both current and paleo temperature sets.

``... The nearly 50 - yr time series shows that the decadal change of the global oceanic evaporation (Evp) is marked by a distinct transition from a downward trend to an upward trend around 1977 — 78.
