Sentences with phrase «upon recent observations»

However, in a nutshell (see their paper for more, and the figure below, taken from that paper), what Brown and Caldeira did was to emphasize the contributions to temperature prediction of the subset of models which are the most skillful at predicting the present based upon recent observations.

Not exact matches

That last point touches upon another observation made by BAML — that while stocks certainly look pricey, certain areas of the market are actually attractively priced, at least compared with recent months.

«It was an exciting thing to stumble upon,» says astronomer and lead author Rok Roškar of the University of Washington, Seattle, who notes that recent observations support the model's conclusion that radial migration of stars might be quite pervasive in the Milky Way.

There are, however, caveats: (1) multidecadal fluctuations in Arctic — subarctic climate and sea ice appear most pronounced in the Atlantic sector, such that the pan-Arctic signal may be substantially smaller [e.g., Polyakov et al., 2003; Mahajan et al., 2011]; (2) the sea - ice records synthesized here represent primarily the cold season (winter — spring), whereas the satellite record clearly shows losses primarily in summer, suggesting that other processes and feedback are important; (3) observations show that while recent sea - ice losses in winter are most pronounced in the Greenland and Barents Seas, the largest reductions in summer are remote from the Atlantic, e.g., Beaufort, Chukchi, and Siberian seas (National Snow and Ice Data Center, 2012, http://nsidc.org/Arcticseaicenews/); and (4) the recent reductions in sea ice should not be considered merely the latest in a sequence of AMOrelated multidecadal fluctuations but rather the first one to be superposed upon an anthropogenic GHG warming background signal that is emerging strongly in the Arctic [Kaufmann et al., 2009; Serreze et al., 2009].

In which case please point to a significant cluster of recent studies (preferably, but not necessarily, based upon observations) which support higher estimates of climate sensitivity.
