Why is 1.5 degrees such a big deal?

  • 0:02 - 0:05
    Why is 1.5 degrees such a big deal?
  • 0:05 - 0:10
    Because to warm our entire planet up
    by 1.5 degrees Celsius
  • 0:10 - 0:12
    requires a lot of heat.
  • 0:13 - 0:16
    All this extra heat melts glaciers,
    which raise sea levels.
  • 0:16 - 0:20
    If the ice sheets of Antarctica
    and Greenland melt completely,
  • 0:20 - 0:22
    millions of people's homes
    will be under water.
  • 0:23 - 0:25
    The extra heat also intensifies weather,
  • 0:25 - 0:28
    making wet places wetter, dry places drier
  • 0:28 - 0:31
    and increasing the ferocity of storms.
  • 0:31 - 0:35
    That 1.5-degree increase
    also won't be distributed evenly.
  • 0:35 - 0:38
    The coldest nights in the Arctic
    might get 10 degrees warmer.
  • 0:38 - 0:42
    The warmest days in Mumbai
    might get five degrees hotter.
  • 0:42 - 0:44
    Over the past 10,000 years,
    we've been lucky.
  • 0:44 - 0:48
    Earth's climate was stable
    and our civilizations flourished.
  • 0:48 - 0:54
    But as our climate gets more unstable,
    so will our economies and our societies.
  • 0:54 - 0:55
    We'll all suffer,
  • 0:55 - 0:58
    and the vulnerable will be hit hardest,
  • 0:58 - 0:59
    unless we act now.
