Sentences with phrase «air temperature trend since»

So we'll assume that the global surface air temperature trend since 1984 has been one of 0.20 °C per decade warming.

Not exact matches

With documented warmer air temperatures in eastern Canada since the 1970s, there has been a trend of earlier ice melting and less ice in general, explained Lavery.
The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.
Even if you restrict the definition of «hiatus» to air temperatures, there are few datasets that actually demonstrate a trend of 0 since circa 2000.
Glaciers and ice caps in Arctic Canada are continuing to lose mass at a rate that has been increasing since 1987, reflecting a trend towards warmer summer air temperatures and longer melt seasons.
The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.
There has been no material trend in surface air temperature during the last 10 years when taken in isolation, but 13 of the 14 warmest years on record have occurred since 1995.
The Western Antarctic Peninsula's surface air temperatures have been cooling rapidly since 1999 («a cooling trend of − 0.47 °C / decade during 1999 — 2014» [Oliva et al., 2017]-RRB-.
The global SST show mostly similar trends to those of the land - surface air temperature until 1976, but the trend since 1976 is markedly less (Table 2.1).
The difference in trend between global SST and global land air temperature since 1976 does not appear to be significant, but the trend in NMAT (despite any residual data problems) does appear to be less than that in the land air temperature since 1976.
However, ~ 80 % of the total warming involved occurred after 1979, and as noted earlier since 1979 the trend in HadCRUT4v4 matches that in the (adjusted) ERA - interim dataset, which estimates purely surface air temperature, not a blend with SST, and has complete coverage.
This provides an upper bound for the surface temperature since the upper air is supposed to have larger trends than the surface (e.g. see Klotzbach et al (2011).
Greenland surface air temperature trends, including at the Summit site, have not shown persistent warming since 1930 in contrast to global average surface temperature (23).
Using computer climate models, climatologists have established that the recent trend of an increasing global average air temperature, especially since the mid-20 th century, is unprecedented and unnatural.
Of course there is uncertainty in the trends (both from fitting the OLS line, + / -0.6 ºC, and structurally, since RSS has slightly different numbers), and there is no expectation that TLT and surface air temperature should have identical trends (overall, TLT should be increasing a little faster than SAT — but this is also subject to noise over relatively short periods).
One would think that the two sources of data would yield quite similar trends and have important similarities since they attempt to measure air temperatures so close to each other.
