Sentences with phrase «warming over the last few decades»

Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

Recent work (e.g., Hurrell 1995, 1996; Thompson and Wallace 1998; Corti et al., 1999) has suggested that the observed warming over the last few decades may be manifest as a change in frequency of these naturally preferred patterns (Chapters 2 and 7) and there is now considerable interest in testing the ability of climate models to simulate such weather regimes (Chapter 8) and to see whether the greenhouse gas forced runs suggest shifts in the residence time or transitions between such regimes on long time - scales.

A globally warm medieval period could be a simple forced response to increased solar, in which case it doesn't imply any larger intrinsic variability than already assumed, and since solar has been pretty much constant over the last 50 years, improvements to our understanding of solar forced climate changes are irrelevant for the last few decades.
