The unarguable damage to the global climate remains the forefront of Western media, recently the most notable being the permanent move to over 400ppm of CO2 in the atmosphere. However, it has now moved beyond the basic recognition of facts to a new generation of questions. What will the effects be? What can we do? Is it too late? This blog will address the latter. Over the last few years increasing amounts of documentaries are being released in regards to the ‘climate tipping point’. The concept posits that a variety of systems all have a threshold whereby they will enter feedback loops, some more devastating than others. Although highly holistic and interlinked Tim Lenton of Exeter University identified 11 potential tipping points:
  • ·         Arctic Sea Ice
  • ·         Greenland Ice Sheet
  • ·         West Antarctica Ice Sheet
  • ·         Yedoma Perma-Frost
  • ·         Ocean Methane Hydrates
  • ·         Himalayan Glaciers
  • ·         Oceanic Circulation
  • ·         Indian Summer Monsoon
  • ·         The Amazon Rainforest
  • ·         The West Africa Monsoon
  • ·         The Thermohaline Circulation


This blog will aim to pursue the discourse surrounding this concept in both academia and mass media while having a greater focus on Arctic Sea Ice. This particular tipping point presents such a danger mainly due to the amplification effect of the Arctic on global climate and its strong connections to key components in each of the other potential thresholds.
