===Medieval warm epoch===
In 1965 he published his study on "The early medieval warm epoch and its sequel", based on "data from the realms of botany, historical document research and meteorology". His view was that "Evidence has been accumulating in many fields of investigation pointing to a notably warm climate in many parts of the world, that lasted a few centuries around A.D. 1000–1200, and was followed by a decline of temperature levels till between 1500 and 1700 the coldest phase since the last ice age occurred."<ref name=Lamb65>{{Cite journal| last1 = Lamb | first1 = H.| title = The early medieval warm epoch and its sequel| journal = Palaeogeography, Palaeoclimatology, Palaeoecology| volume = 1| pages = 13–37| year = 1965| doi = 10.1016/0031-0182(65)90004-0| bibcode = 1965PPP.....1...13L}}</ref> The paper included a series of diagrams of temperatures in central England over the period, simplified in a 1982 version adjusted to account for "probable under-reporting of mild winters in Medieval times" and "certain botanical considerations" including historical records of vineyards in southern and eastern England.
