Sentences with phrase «scale trends evident»

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).

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).

Not exact matches

Given that the past 30 — 50 years is a relatively short period for evaluating long - term trends, the SST trends themselves could be viewed as a manifestation of large - scale modes of multidecadal Pacific variability (e.g. Zhang et al. 1997; Deser et al. 2004) or as part of the century scale positive SST trends associated with climate change (e.g. Deser et al. 2010); it is likely that both multidecadal climate variability and climate change have contributed to the SST trend pattern evident in Fig. 9 and used to force the model.

Several analyses of ring width and ring density chronologies, with otherwise well - established sensitivity to temperature, have shown that they do not emulate the general warming trend evident in instrumental temperature records over recent decades, although they do track the warming that occurred during the early part of the 20th century and they continue to maintain a good correlation with observed temperatures over the full instrumental period at the interannual time scale (Briffa et al., 2004; D'Arrigo, 2006).
