What will life at 1.5+ degrees look like?

We are officially out of time to prevent hitting 1.5 degrees. Yep - earlier last week, the World Meteorological Organisation said that we are going to hit 1.5 degrees of global heating by 2027, which is just two years away.

So I thought we’d have an episode about what that really means - because what actually changes at 1.5 degrees? And what happens if we go beyond that?

In this episode:

  • Why scientists identified 1.5 degrees as a milestone
  • What a 1.5 degree increase will actually cause
  • Where we are today with global heating
  • The damage to the oceans and natural world from global warming
  • Why a 1.5 degree change is now baked in
  • What terrifying things happen at 2 degrees
  • The places that could become uninhabitable in the next few decades
  • The huge impact on cities and the losses we can expect over the next 80 years
  • The big impacts on crops, people, and health at 2 degrees
  • The economic impact we can expect from climate change over the next few decades
  • What happens at 2.7 degrees, which is expected by 2100
  • Why I don’t think this will be our future
  • The single most powerful thing you can do to prevent this dark future
