Global warming is fundamentally changing human psychology by making people more likely to take dangerous risks.

A one-degree Celsius increase in lifetime temperature is linked to a significant drop in risk aversion across the globe. Climate change is usually discussed in terms of weather and economics, but its most profound impact may be on our decision-making. As the planet heats up, people are becoming statistically more prone to gambling and risky investments. This shift could lead to more volatile markets and more aggressive social behaviors as the climate continues to warm. It suggests that environmental stability is a key pillar of psychological caution.
