Climate Change Linked to Human Brain Shrinkage: Study Reveals Startling Cognitive Consequences
A study conducted by cognitive scientist Jeff Morgan Stibel has revealed a surprising link between climate change and a decline in the size of the human brain. By analyzing climate records and human remains spanning 50,000 years, the research found that periods of warmer climates were associated with a significant reduction in average brain size compared to cooler ones. The study highlights the importance of understanding the impact of climate change on human brain size and behavior, raising concerns about the potential cognitive consequences of ongoing global warming. Other factors such as ecosystem elements, indirect climate effects, or non-climate factors like culture and technology may also contribute to changes in brain size.
