This Is Different

This is why it’s different:

  • It’s happening much faster by orders of magnitude.
  • It’s happening in a context of tremendous habitat fragmentation and already-damaged natural systems due to destructive agricultural and settlement practices.
  • We now have a global civilization brimming with vulnerable people, farms, and infrastructure.
  • For comparison, at the coldest part of the last ice age, the planet was only 6 degrees Celsius colder than today. The last time it was 6 degrees warmer was 55 million years ago – when there were rain forests in Greenland. It was also 6 degrees Celsius warmer than today during the great Permian extinction 251 million years ago.
