1.5ºC - A New Boundary For Global Warming?

Nations have agreed to aspire to a boundary of 1.5ºC global mean average temperature rise. But to what degree is this new "icon" for limiting climate change based on science and can we even achieve it?

Kevin Anderson, Deputy Director of Tyndall Centre for Climate Change & Professor at University of Manchester, UK
Jason Box, professor in glaciology at the Geological Survey of Denmark and Greenland

Interview by Nick Breeze with Dr Natalia Shakhova and Dr Igor Semiletov

A new scientific paper published in Nature Communication Journal demonstrates that the mechanisms of destabilisation of subsea permafrost, contrary to previous claims, provide new insights into increased emissions from the worlds largest deposits of methane, that exists in the East Siberian Arctic Shelf (ESAS).

The subsea permafrost has for thousands of years acted as a seal, restricting the flow of gas through the water column to the atmosphere. This paper clearly shows that permafrost degradation and the occurrence of gas migration pathways are key factors in controlling the emissions.  

 

Comment: Watching our recent interview with Christiana Figueres, David Tattershall (Envisionation Limited) responded with considered concern with respect to her answer to the question on the reduction of emissions from the aviation industry.

Just to recap, here is the transcripted answer with Tattershall's response below:

 

The lady who ushered in the Paris Agreement now wants to ramp up the pace and ensure the world reaches peak emissions by 2020, leading to total decarbonisation by 2050. The whole campaign hinges on the a new report that cites 2020 as a critical milestone for stemming the effects of climate change.

Christiana Figueres is persuasive and influential but in light of recent world events that include the destabilisation of the EU as a political block, and the openly anti-climate action administration of President Trump, it is very clear that the world has changed since Paris.

READ THE COMMENT: Does Figueres interview give clues as to why we went backwards from Copenhagen to Paris?

 

Centre for Science and Policy (CSaP): 2017 Climate Change Seminar Series

Science, politics, knowledge management, innovation and markets all play a role in climate change action, but what is the role of the University of Cambridge as an ‘anchor institution’ for these? Bringing together speakers spanning the worlds of research and policy, this series of events will explore how the multifaceted aspects of climate change action can come together to help us make the right decisions for the long run.  

The window of opportunity is closing… but the price of failure is still too high!

The rate of ecological destruction is now so bad that the fate of our civilisation literally hangs in the balance. The loss of the Arctic polar ice cap, the melting from above and below of Antarctica, the culling and collapse of forests and dying oceans, failing ecosystems, our atmosphere burdened with hundreds of billions of tonnes of extra greenhouse gases, and still each week scientists report more broken links in the chains of interconnectedness that sustain each one of us, rich and poor, on this planet. Despite all this, the great human enterprise built on a foundation of carbon, rumbles on in search of new fixes.

 

Peter Wadhams has achieved many accolades and held positions such as Director of the Scott Polar Institute in Cambridge Uk, among a great many others. He has been on more than 50 research trips to the polar regions and, of special interest to those studying the demise of the Arctic ice cap, he has been under the ice on 6 submarine expeditions.
