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.
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.
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.

Due to my youth with those who went to war who could have obtained deferments and certain experiences in my family I have a deep afinity for those who risk their lives so that we are free. I find what occurred this weekend utterly offensive particularly since Trump obtained deferments from the Vietnam War with a supposed heel spur shortly after he had claimed
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.
In this serialised interview with co-founder of the Climate Psychology Alliance (CPA), Adrian Tait, we explore different aspects of the psychology that has become a key theme in discussions around how we cope with climate change information and also how we disseminate that information.
The scope of global fossil fuel divestment has doubled over the past 15 months, with institutions and individuals controlling $5.197 trillion in assets pledging to divest. The announcement comes on the first anniversary of the Paris Agreement on climate change.
Speaking at COP22, outgoing Secretary of State and one of the world's most vocal champions of action to tackle the manmade climate crisis, John Kerry, delivered a cautiously optmistic but realistic address to the press at COP22 in Marrakesh. This speech was in contrast to Kerry's upbeat speech in Paris at COP21 a year earlier when the nightmarish reality of a Republican administration in the US was unimaginable. The world has changed and in this excerpt Kerry identifies the challenges and the realities of what we are facing.

“The current expected climate trajectory… effectively dooms the ice sheet!”
Spelte Glacier loses “Manhattan Island” sized chunk of ice
Professor Jason Box, a glaciologist at the Geological Survey of Denmark and Greenland, describes how the “largest ice shelf in Greenland has a northern tributary… and now this Manhattan Island sized ice shelf fragment has broken away” in what he calls a “spectacular event”.

These two experts about the risks posed by climate change and the urgency with which we need to respond.
This call is hosted by Nick Breeze of Envisionation.co.uk and covers the topics of climate science, political response and the need for a wider understanding of the huge threat humanity faces from abrupt climate change.

A forest with greater diversity of plants can better adjust to climatic stress. Now for the first time, a team of scientists can show this in computer simulations of the Amazon region by accounting for its amazing diversity of trees. Biodiversity can hence be an effective means to mitigate climate risks and should not only be seen in the context of nature conservation.

Climate disasters like heat-waves or droughts enhance the risk of armed conflicts in countries with high ethnic diversity, scientists found. They used a novel statistical approach to analyze data from the past three decades. While each conflict is certainly the result of a complex and specific mix of factors, it turns out that the outbreak of violence in ethnically fractionalized countries is often linked to natural disasters that may fuel smoldering social tensions. This finding, to be published in the Proceedings of the US National Academy of Sciences, can help in the design of security policies – even more so since future global warming from human-made greenhouse-gas emissions will increase natural disasters and therefore likely also risks of conflicts and migration.
