What people are saying

Discussions reflect a strong interest in the historical population sizes and their relation to climate, with posts emphasizing the significance of findings like the population decline and recovery periods, using tone of curiosity and recognition of the study's importance, which underscores their engagement and moderate impact.

AgreementModerate agreement

Most discussions acknowledge the significance of the research, with some highlighting the fascinating population estimates and their implications for understanding human resilience.

InterestHigh interest

Posts show high interest, especially with enthusiasm about the historical population figures and how they relate to climate impacts.

EngagementModerate engagement

Participants discuss specific data points and historical context, indicating a reasonable level of engagement without deep technical debate.

ImpactModerate impact

The discussions seem to influence perspectives on human survival and climate impacts but do not suggest a major shift in understanding or policy.

Abstract in brief

  • The study models how human populations in Europe changed from before the Last Glacial Maximum (around 30,000 years ago) through the coldest period of the ice age, showing that climate greatly influenced population size and distribution.
  • Human population declined significantly during the LGM, reaching a low of about 130,000 people around 23,000 years ago, but started to recover during the warmer periods in the Late Glacial, reaching nearly 410,000 by 13,000 years ago.
  • Despite extreme cold, large areas of Europe (about 36%) remained suitable for human habitation, and the population dynamics derived from climate and ethnographic data closely matched archaeological findings, highlighting climate as a key factor in human survival and expansion during this time.]

@Alexander_Lees @ChristosA89 @PaulDolman3 @Rebirding1 @NaturalEngland @TonyJuniper The entire pop. for Europe ca. 12kya is estimated at <400,000, with perhaps 5-10% of that number in Great Britain - basically the current population of Rutland - & no one at all on the island of Ireland until 10.5kya.

Greta sees the problems, but not what has been done in the past. She needs to be in history class learning about population and human resilience. Hey, @GretaThunberg ! Human population dynamics in Europe over the Last Glacial Maximum https://t.co/iFRPJthuvv https://t.co/zY1aAGB8zh

@fractheDevonian @_ClimateCraze It’s a fair response for sure. However, as this article postulates, there were 130-410k humans through this period with population density in the inhabited area between 2.8 and 5.1 persons / 100 km2 (Europe)… it’s now 34 / 1km2. Approx 86096.2% increase! https://t.co/vsUqiV53Xi
