Cambridge University geoengineering

On the 10th July we were able to attend and record the Geoengineering Debate in Cambridge. Here is the list of participants in the debate and the link where each segment can be watched. The following quote is from Professor Martin Rees's preface to the Royal Society report on geoenegineering (read by Dr Hugh Hunt in the opening):


"The continuing rise in the atmospheric concentration of greenhouse gases, mainly caused by the burning of fossil fuels, is driving changes in the Earth's climate. The long-term consequences will be exceedingly threatening, especially if nations continue 'business as usual' in the coming decades. Most nations now recognise the need to shift to a low-carbon economy, and nothing should divert us from the main priority of reducing global greenhouse gas emissions. But if such reductions achieve too little, too late, there will surely be pressure to consider a 'plan B'—to seek ways to counteract the climatic effects of greenhouse gas emissions by 'geoengineering'"

For the motion:


Oliver Morton is The Economist's briefings editor. Before coming to The Economist as energy and environment editor in 2009, he was the chief news and features editor of Nature, the international scientific journal. He specialises in the energy business, climate science and policy, and other green issues. He is the author of "Eating the Sun: How Plants Power the Planet", a study of photosynthesis, its meanings and its implications, and "Mapping Mars: Science, Imagination and the Birth of a World".
 

Peter Wadhams is Professor of Ocean Physics in the University of Cambridge, and is an oceanographer and glaciologist involved in polar oceanographic and sea ice research and concerned with climate change processes in the polar regions. He leads the Polar Ocean Physics group studying the effects of global warming on sea ice, icebergs and the polar oceans. This involves work in the Arctic and Antarctic from nuclear submarines, autonomous underwater vehicles (AUVs), icebreakers, aircraft and drifting ice camps. He has led over 40 polar field expeditions.
 

Against the motion:


Helena Paul works with EcoNexus on the impact of emerging technologies on biodiversity, communities, food sovereignty. Technologies include synthetic biology, geoengineering, GM crops and trees. I also focus on the impact of biofuels, biomass production, bioenergy generally on land and biodiversity. EcoNexus researchers are concerned that not enough account is taken of the complexity of natural systems when making interventions.
 

Matt Watson is a Reader in earth Sciences at the University of Bristol.  He is the Principle Investigator for SPICE (Stratospheric Particle Injection for Climate Engineering). His research involves inversion of remotely-sensed data to retrieve physical parameters of volcanic plumes and clouds over several spatial scales, using both ground- and satellite-based techniques.
 

In the chair:


Hugh Hunt is a Senior Lecturer in Engineering at the University of Cambridge.  He leads the "Delivery Methods" part of SPICE and is the engineer in charge of the 1km testbed that was cancelled.  His other research interests include wind-turbine reliability, tidal power and flood defences, noise and vibration from railways, gyroscopes and boomerangs.  He has also made several documentaries for Channel Four and PBS Nova on subjects such as Dambusters' bouncing bombs, the Colditz glider and WW1 Zeppelins.

The World Economic Forum (WEF) is the first of the big global conferences of 2020 that will lead us to COP26 in Glasgow where governments will be under enormous pressure to agree safe and realistic action for the future. With Extinction Rebellion (XR) and other protest groups converging in the Swiss alpine town of Davos, I asked their leading spokesperson, Rupert Read, whether the tone being set here is encouraging:

 

The UK is readying itself for the presidency of the 26th Conference of the Parties (COP26), to be held in Glasgow in November 2020. In the wake of the failure of COP25, a British presidency must bring to bear its accumulated powers in diplomacy, persuasion, purpose, and determination, to recreate trust in the Paris accord, kickstarting a new decade of meaningful achievements on safeguarding our collective future. 

 

Seeing the extent of environmental destruction in 2015, Jackie Bond started volunteering for the Green Party in Southwark, SE London. In the last year, aside for standing for the Greens in Vauxhall and doubled their share of the vote, she has worked extensively with Extinction Rebellion, organising civil actions in pursuit of radical climate action. In this interview with Nick Breeze, Jackie discusses how she got involved in XR, why we need to put the climate crisis at the centre of policymaking, and her strategy for creating change in the UK.

 

Longstanding climate change siren, Professor James Hansen talks to Nick Breeze about negative emissions technologies NET's, accelerating emissions, the need for international and intergenerational cooperations. Is he optimistic?

 

Addressing a wine industry on the frontline of climate change, Former President Obama said: “We are speeding our car towards the cliff at a very fast rate”. The audience and former president were invited to the launch of this new initiative by 326yr old port company CEO, Adrian Bridge, who is calling for solutions, saying “what we need to do is stop talking and start doing!” Nick Breeze reports.

 

A three day hearing at the High Court is in process that will decide whether an injunction be granted, effectively preventing any campaigning that might negatively impact the economic interests of UKOG and their associated companies.
