Sites in Canada and Africa were warmer than today throughout nearly the entirety of the Holocene.
Canada
Per a new study, eastern Canada mean summer temperatures are 13.6°C and July temperatures average 15°C today. For nearly all of the Holocene the region was 1-1.5°C warmer (16.5°C, July) than it is now.
In other words, except for a brief period during the Little Ice Age, the present temperatures are the coldest of the last 8000 years.

Scientists indicate that “in the last 150 yr, the reconstructed temperatures do not indicate a warming during this time” at sites in the Canadian Arctic (Fortin and Gajewski, 2016). Modern temperatures are 2-3°C colder than anytime in the last ~7000 years.

Scientists (Campbell-Heaton et al., 2021) studying another region in Arctic Canada also recently determined the ground surface winter temperatures now (1981-2016) average -33°C, whereas about 9000 to 10,000 years ago ground surface temperatures reached -18°C at this location, or 15°C warmer than present. Winter air temperatures, were, on average, “6-8°C warmer than today” at this time too.
