Sentences with phrase «decadal variability suggests»

The history of decadal variability suggests that temperatures will decline (since 1998) over the next couple of decades — well before which the entire science community is utterly discredited.

2) Reversibility of the decadal variability (which suggests natural variability) such as an absence of volcanic perturbation eg Joshi and Shine 2003 http://journals.ametsoc.org/doi/pdf/10.1175/1520-0442%282003%29016%3C3525%3AAGSOVE%3E2.0.CO%3B2

Shifts at decadal scales in the form of rivers — between low energy meandering and high energy braided forms — that suggested decadal variability of rainfall.

While the correlation displays decadal - scale variability similar to changes in the interdecadal Pacific oscillation (IPO), the LDSSS record suggests rainfall in the modern instrumental era (1910 — 2009 ad) is below the long - term average.»

Our results suggest that the decadal AO and multidecadal LFO drive large amplitude natural variability in the Arctic making detection of possible long - term trends induced by greenhouse gas warming most difficult.

It should be noted that we are not suggesting here that all decadal sea level variability is related to TWS, but do find TWS variability to play a significant role in sea level changes on the timescale of a decade.»

There is peer reviewed science that suggests — as a result of Pacific variability especially — that the world is not warming over the next 10 years (Mochizuki et al 2010, Swanson et al 2009, Tsonis et al 2007, Keenlyside et al 2008)-- albeit with immense uncertainties surrounding the origins and limits of decadal variability.

For myself, I've suggested that 2005 - 2025 is likely to be below 0.2; and specifically somewhere from 0.15 to 0.2, but that's a quick guess not a calculation, based on rough consideration of decadal scale variability /

The solar amplification mechanism — the only real candidate for the vigorous decadal to centennial variability seen in the data — suggests further cooling this century is likely.

The solar amplification mechanism — the only real candidate for this vigorous decadal to centennial variability — suggests further cooling this century.

Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the expected influence of human - induced climate change.3 The signature of global warming has also been identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface temperatures in the northern Pacific Ocean.4

It suggests that the ocean's natural variability and change is leading to variability and change with enhanced magnitudes over the continents, causing much of the longer - time - scale (decadal) global - scale continental climate variability.

This suggests great variability in the past, not only on the decadal basis but in individual years and the seasons within those years.

Proxy records that document summer precipitation are much less common and, of those that do exist, some suggest wetter summers during the medieval period (22, 45 — 47), whereas others indicate decadal variability of both drought and wetness (48).

Modeling studies suggest that we need ~ 500 years of observations to sample the full range of ENSO decadal variability (e.g., Wittenberg 2009).

It's not the first paper to suggest that the initialisaiton of natural internal cycles of variability is important in decadal forecasting, nor the first to make a decadal prediction.

On text noting high decadal variability in Arctic temperatures, Canada, supported by Norway, suggested removing a specific reference to a warm period observed from 1925 to 1945.

Increasing attention is being paid to IPCC misrepresentations of natural oceanic variability on decadal scales (Compo and Sardeshmukh 2009): «Several recent studies suggest that the observed SST variability may be misrepresented in the coupled models used in preparing the IPCC's Fourth Assessment Report, with substantial errors on interannual and decadal scales (e.g., Shukla et al. 2006, DelSole, 2006; Newman 2007; Newman et al. 2008).
