Sentences with phrase «early century warming»

Choosing that precise lowest year is «cherry - picking» the start date, ignoring the variation in a way to mazimize the statement of early century warming.

In fact, one of the realizations (upper right) happens to capture considerable early century warming, peaking near mid-century in high northern latitudes, comparable to that observed.

Basically, climate scientists ran their models against history, and found that even with their SO2 plug, they still didn't match well — they were underestimating early century warming and over-estimating late century warming.

The implication is that events such as the early century warming are not as significant as when the a warming of similar magnitude is seen in the zonal mean profile at lower latitudes.

If one uses the midpoint of that earlier variation to define the start of the 20th century warming trend, one starts at a date closer to 1920, and knocks a full 0.1 + C off the early century warming.

If one uses the top of that variation, so that we only consider previously -(recently)- unobserved temperature regimes, one finds that we do nt return to the top of the previous range until about 1930, and there is only about 0.25 C «novel» early century warming.

Since that early century warming, temperatures have risen well - beyond those achieved during the Medieval Warm Period across most of the Globe.

Since that early century warming, temperatures have risen well - beyond those achieved during the Medieval Warm Period across most of the globe.

The early century warming was mostly natural — as was at least some of the late century warming.

For those of you who love quantification, the warmest 10 - year period in the early century warming was from 1936 to 1945 and had a magnitude of 0.78 °C above the baseline.

As I discussed previously, the Arctic has warmed rapidly over the last century but this warming has occurred in two phases with an early century warm period (1910 - 1950) and a late - century warm period (1975 - present).

Based on this Figure, it is widely apparent that the current warm period far exceeds the early century warm period in both rate (slightly) and magnitude.

The warmest late century 10 - year period occurred from 2001 to 2010 with an anomaly of 1.56 °C, 2x greater than the early century warming.

This would suggest that the combination of anthropogenic forcing and internal variability may be sufficient to account for the observed early - century warming (as suggested by, e.g., Hegerl et al., 1996), although other recent studies have suggested that natural forcing may also have contributed to the early century warming (see Section 12.4.3).

But for now, I leave you with the question — If we don't know what natural forcing caused the early century warming, then how can we say with confidence it stopped after 1950?
