Sentences with phrase «latest warming episode»

Kent Moore, a professor of atmospheric physics at the University of Toronto, who published a study in 2016 linking the loss of sea ice to these warm events in the Arctic, said a number of factors may have contributed to the latest warming episode.

Not exact matches

I've found myself at the center of such episodes more than once, as a result of what's become known as the iconic «hockey stick» diagram that my co-authors and I had published in the late 1990s — a graphic display of the data that made plain the unprecedented rate of global warming.

Therefore one would expect to see the rate of warming between the late 197s and the late 1990s to be greater than the rate of warming that occurred during the earlier two warming episodes.

Given that it can not explain those warming episodes and given that it accepts that CO2 did not cause those warming episodes, it makes its logical failure with respect to the late 1970s / late 1990s warming even more pronounced.

This rate (0.28 degC per century) is very different to the rates referred to by Phil Jones for the warming periods detailed in my above comment, so the slow down is very apparent when the last 20 years is compared to the rate of the 1860 to 1880 warming episode which was slightly greater than the 1920 to 1940 warming episode, and also slightly greater than the late 20th century warming episode

But there is no acceleration in the rate of warming between that observed in the late 1970s to late 1990s, and that observed in the two earlier warming episodes of 1860/80 and 1920/40.

... In light of their recent findings, Davies et al. say there is «little support for the existence of a «permanent El Niño»... that there was robust ENSO variability in past «greenhouse» episodes and that future warming will be unlikely to promote a permanent El Niño state,» which point they also emphasize in the final sentence of their abstract, where they say that their evidence for robust Late Cretaceous ENSO variability «does not support the theory of a «permanent El Niño,»» [Andrew Davies, Alan E.S. Kemp, Graham P. Weedon, John A. Barron 2012: Geology]

After reviewing evidence in both the latest global data (HadCRUT4) and the longest instrumental record, Central England Temperature, a revised picture is emerging that gives a consistent attribution for each multidecadal episode of warming and cooling in recent history, and suggests that the anthropogenic global warming trends might have been overestimated by a factor of two in the second half of the 20th century.

As in later eras, Cretaceous warmth led to ocean stratification and anoxia; evidence shows many warm «spikes» accompanied by such anoxic episodes.
