Interviews And Articles by Nick Breeze
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.
It was during these submarine trips that Professor Wadhams started noticing what could not be seen from satellites measuring the sea ice area; namely that the volume of the ice was being greatly melted from below. This discovery showed that the dynamics of change in the Arctic were more complex and happening far faster than had previously been conceived.
Research lecture and Explorer’s Journey
Wadhams begins by taking us through the essential steps of how ice is formed, the difference between single year and multi-year sea ice, and how that fits into the context of deep time history of life on Earth. We get exposure to the language of polar researchers as words like frazil ice or polynyas as mechanisms and processes are clearly defined like pieces of a jigsaw that eventually come together to construct a larger more complex picture.
What is described and the illustrations that accompany the text have an otherness that we might feel when someone is describing the surface of another planet. But that really is the rub. It really is our planet that Wadhams is scrutinising; an essential, delicate, sensitive and rapidly changing part of the Earth system.
Meeting with Professor Wadhams at COP22
I caught up with Wadhams at the UNFCCC COP22 climate change summit in Morocco in November of 2016 and asked him to summarise ‘A Farewell To ice’. After jokingly apologising to Ernest Hemingway for the appropriation of his title he said:
“The top end of the world was always white… that was the way it was! Until now, in the summer at least, it is now blue. We have separated North America from Asia in a way that it wasn’t separated before.
To compare the way I perceived - because I go there every year - how the ice has changed as I’ve watched and what that means physically for the planet in terms of the warming rate, changes in sea-level, changes in areas of snow, all things that spin off from the loss of ice in the Arctic. It’s a farewell to ice personally and for the planet.”
Differences with the establishment & “bingo” predictions
Wadhams has in more recent times found himself at odds with a scientific establishment that he says has an over reliance on computer climate models that aim to simulate specific Earth systems in order to determine what the future holds.
His main contention is that the models are not adequate and miss out many processes that are impacting the sea ice especially and causing the Arctic to melt out at a much faster rate than modellers have calculated.
One practise that has hindered his message in recent years is the willingness to answer journalists questions about “what year will we see an ice free Arctic?”. I personally think this is a question that does not need answering. The data clearly shows what is happening in the Arctic and at the time of writing this review (Christmas 2016) the Arctic is is experiencing a extraordinary, unprecedented in human terms, heat wave at the North Pole.
What we see is an unfolding trend that is as Professor Wadhams has predicted for a long time. Whether it occurs fully this year of in five years is not really important. What we do about it is!
Interconnectedness: outcomes of an ice free world
As climate scientists study Earth systems, it is becoming increasingly clear that the planet is very much interconnected. The very idea of a system that operates in a responsive manner, should not be too difficult to understand. Humans are adding around 40 billion tonnes of greenhouse gases to the atmosphere each year and this is tipping us into a hotter epoch faster than every seen before.
With each fraction of degree we add to our atmosphere we are locking in changes that will radically change civilisation. The loss of the Arctic has many interactions that are affecting Greenland, the jet stream that keeps Britain within a band of warmer climatic conditions considering our latitude, as well as changing weather patterns around the world.
As the Arctic turns from a white reflective surface to a dark heat absorbing one, the amount of increased warming is calculated to be the equivalent to the total warming we have experienced from our own greenhouse gas emissions in the last 25 years. The implications will impact every aspect of human life on Earth from the social, political, ethical and existential, as we strive to survive on our destabilised planet.

Angela Merkel’s chief science advisor describes Michael Gove’s comments on climate change as “A false trade off used all the time by the incumbents”
Earlier this week Environment Minister Michael Gove stated that he was convinced “climate change is a danger”, stating that it “is one of the biggest threats and challenges to biodiversity in the UK”.
By localising the issue to the UK, Gove seeks to belittle the global risk posed by climate change. This week, German Chancellor Angela Merkel’s chief science adviser and founding director of the Potsdam Institute, Professor Schellnhuber was in London speaking at the Royal Society. When I asked him to respond to the Environment Minister’s comments he replied:
Interview: Anton Golub, cofounder of Swiss blockchain exchange LYKKE
In part 1 of this wide ranging interview, Anton Golub discusses why the world needs Lykke, the truth about financial regulators and why only 1% Initial Coin Offerings (ICO’s) they assess make it onto the exchange.
Anton Golub: The core vision of Lykke is the vision of Richard Olsen, the founder of Lykke. I am a cofounder. I met him seven years ago when I joined him for an internship.
I sat down to eat my croissant and he sat down next to me and said: “Anton, we have to completely change the financial system. It totally doesn’t work. Everything is broken inside.”
Subsea permafrost on East Siberian Arctic Shelf in accelerated decline
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.
Christiana Figueres: business must lead us to zero 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.
Lecture: Data analytics for climate decision-making
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.
Why we need the Cambridge Climate Lecture Series
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.
