Stephen Hawking, before his death in 2018, predicted that Earth’s unchecked growth in population and energy demand would cause it to physically glow red-hot by 2600. At the 2017 Tencent WE Summit, the celebrated physicist warned that such exponential increases aren’t sustainable and pose severe risks.

Hawking also noted the overwhelming pace of scientific output in the future, indicating a data flood impossible to keep track of. His warnings included threats from nuclear conflict, pandemics, and the development of AI, highlighting the complex challenges humanity faces.

Addressing climate change, Hawking suggested Earth could transform into an inhospitable environment akin to Venus due to global warming, though such changes would take centuries or millennia.
While NASA distances itself from the precise prediction, it confirms the reality of global risks that need urgent attention. Hawking’s warnings remain a vital impetus for global action on climate and technology.
