'German and Russian scientists say that it is normal for an interglacial period like the one just ending to finish with one or more brief - in geological terms - spells of warming before the glaciers return.Here comes the ice...
According to boffins based at the Helmholtz-Zentrum für Umweltforschung (UFZ) and at the Russian Academy of Sciences, in the Earth's history thus far there have been eras where the glaciers covered much of Europe, lasting about 100,000 years. These are separated by warmer interglacial periods lasting around 10,000 years. We are currently at the end of an interglacial era called the Holocene.
The scientists, looking into the last interglacial period - the Eemian - which ended around 115,000 years ago, say they have found that that it ended with "significant climate fluctuations" before the rule of the glaciers returned.'

Yes! Before the politicisation of climate research, when scientific methods were applied to gathered data, there were warnings of an approaching ice age, not warming. Then Mann, and like-minded teams of "Palaeoclimatologists", interpreted (by dubious formulae & assumptions) various proxies, mainly tree rings and ice cores, to predict warming instead. It's likely that the original analyses were nearer the truth! Many people are confused by recent extremes of WEATHER and still believe the mantra of warming, but increasingly robust studies predict cooling.
