In this episode we uncover a shocking truth revealing how scientists are linking climate change to shrinking human brains, raising urgent questions about the future of our intelligence and survival. A new study by cognitive scientist Jeff Morgan Stibel from the Natural History Museum in California analysed climate records and human remains spanning 50,000 years, uncovering a consistent pattern where warmer climates correlated with a reduction in average brain size. His findings suggest that during the Holocene warming period humans experienced a decline of more than 10 percent in brain size, with adaptation taking thousands of years. The research warns that ongoing global warming could pose serious risks to human cognition, though other factors like culture and technology may also play a role. With experts sounding alarms about how even small reductions could impact physiology and behaviour, this discovery highlights an urgent need to understand the hidden consequences of climate change.
