Earth past its safe limits for humans, scientists say

Human activities have pushed seven of eight earth system boundaries beyond their safe limits, risking planetary and human health, according to a study by a group of the world’s foremost scientists.

Earth past its safe limits for humans, scientists say
  • Earth is already past safe limits for humans due to temperature rise, water system disruption, and destruction of natural habitats.
  • Human activities have pushed seven of eight earth system boundaries beyond their safe limits that indicate the threat to planetary and human health.
  • The study identifies the limits after which humans will suffer significant harm such as lack of access to clean water, lower food security, and displacement or loss of work.
  • The safe limit for global temperature rise is 1C higher than pre-industrial times, but it is already at least at 1.1C, or as much as 1.2C.
  • All earth system boundaries are interconnected, overshooting the safe limit for one can have a knock-on impact on others.
