In 1990, Tom Karl and the IPCC showed that Earth was much warmer 900 years ago, during the Medieval Warm Period....in 1995 the Medieval Warming Period was dismissed and by 2001 it was removed from IPCC (3rd Assessment)
5-7°C. Since the end of the last ice age, about 10,000 BP, globally averaged surface temperatures have fluctuated over a range of up to 2°C on time scales of centuries or more. Such fluctuations include the Holocene Optimum around 5,000-6,000 years ago. the shorter Medieval Warm Period around 1000 AD (which may not have been global) and the Little Ice Age which ended only in the middle to late nineteenth century. Details are often poorly known because palaeo-climatic data are frequently sparse.
The late tenth to early thirteenth centuries (about AD 950-1250) appear to have been exceptionally warm in western Europe, Iceland and Greenland (Alexandre 1987, Lamb, 1988) This period is known as the Medieval Climatic Optimum. China was, however, cold at this time (mainly in winter) but South Japan was warm (Yoshino, 1978). This period of widespread warmth is notable in that there is no evidence that it was accompanied by an increase of greenhouse gases

Oh, why not just make up your own serving of word salad and move on to something more interesting than dialog with a climate-change-denier chatbot and time-waster?
