In the last two decades, the discussion of climate change and its bad effect on the earth is going on all over the world. Most countries are constantly researching ways to deal with it. To prevent global warming, work is being done on reducing the emission of green house gases. Climate change is causing the weather around the world to behave strangely. Now a new study has shown that climate change is directly affecting the human brain.
Jeff Morgan Stibble, a scientist and researcher at the Natural History Museum of California, explained that there is a direct link between climate change and the reduction in human brain size. Researcher Stibble gathered skull size information from 10 published sources for the study. They took 373 measurements from 298 human bones that were 50,000 years old. According to Science Alert, scientist Stibel studied climate records and human remains from this period. In his analysis, he described how humans are affected when there is environmental stress.
The research findings reveal the impact of climate change on human brain size and behavior. Stibble incorporated global temperature, humidity and precipitation records into his study. As per the study report, there is a decrease in the average brain size during hot climate as compared to cold. Previous studies on the reduction in the size of the human brain encouraged Stibel to conduct new research. Stibel stresses the need to understand changes in the human brain over time.
Researcher Jeff compared the size of the human brain to four climate records. It also included data from the European Project for Ice Coring in Antarctica Dome Sea. It has provided accurate temperature measurement for over 8,00,000 years. Earth has seen many climatic ups and downs in the last 50 thousand years. It also includes the Last Glacial Maximum. It is the period in which the temperature remains cool for a long period of time. This was only until the late Pleistocene. This was followed by an increase in average temperature in the Holocene period.
Stibble has expressed great dismay over some of the studies being done in this direction. According to him, we know that the brain has evolved over a few million years in all species. We still don’t know much about the broad evolutionary trend. To get an accurate idea of brain size, he also estimated body size. Geographic region and gender were also examined. To minimize errors in research, he divided the fossils into four groups based on their age.
