En sterk illustrasjon av hva som menes med 'tipping point' finner du på videoen på youTube, der forsker Jay Zwally blir intervjuet. Se videoen her.
Forsker hos NASA Goddard, Jay Zwally, jobber med is-satelittdata fra Arktis og sier følgende:
The sea ice is decreasing faster than all the models predicted. We not only have the warming of the atmosphere, we have a warming of the ocean that is affecting this. It has been surprising to everybody, this decrease in area. This is a marked departure, and this is suggesting to us that maybe we are getting at this tipping point.
