Geoengineering Debate - University of Cambridge

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'"


Watch the debate here:

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.


Debunked Or Defunct; Is Clive James Really An Able Commentator On Our Times?

By Nick Breeze

I must admit to not having heard of Clive James for a couple of decades or more. Last I saw he was hosting a television talk show series that featured a Cuban singer called Margarita Pracatan. So it was with an open mind that I read this review of a biography of the political theorist Thomas Robert Malthus by Robert Mayhew in Prospect Magazine.


Clive James And Margarita Pracatan

Clive James and Margarita Pracatan

James immediately states that “Malthus was wrong that population growth would lead to famine” and asks “Why are his ideas still popular?”. Alarm bells chime in the distance. Malthus is very famous for his conclusions about population growth and natures ability to feed it. The human population has gone from 2bn to 7bn in 85 years [1]. What makes his conclusions more prescient is the enormous body of scientific research that estimates that the Earth’s human carrying capacity has exceeded its resource capacity to sustain us. We are now in exponential population growth, whilst all of our life support systems (forests, oceans, agriculture, water, etc.) have become stressed and are at risk of collapse. Although James would undoubtedly describe this as alarmist, I would certainly assert that it is alarming!

What becomes quickly apparent is that James does not care much for any form evidence in making his grand put downs of the scientific establishment. He prefers statements alluding to his own wisdom instead, such as “… I know quite a lot about mass media, having worked in that area all of my life.” The reader should be reminded that James’s mass media career peaked over two decades ago and, from a media perspective, the pre-internet world was a very different place. The contemporary world, he seems to have no knowledge of at all.

There are so many incorrect statements (with no citations of evidence except “…all the statistics agree…”) that I’ll only highlight a few. James is certain that food security on the planet “will be abundant for years to come.” This seems quite opposed to what is coming out of the scientific studies that show that increased soil erosion, weather anomalies, water and energy shortages, have put the global food baskets under considerable stress. [3, 4].

James cannot abide the author of the book, Robert Mayhew, seemingly because he, himself, does not believe in the seriousness of climate change. All criticisms are framed around this premise, existing without any evidence and with (oddly amusing) demonstrations of James’s own wit in tackling the subject. One of the best lines is as follows: “… I speculated aloud that the famous 97 per cent consensus among scientists was perhaps only a consensus among climate scientists…” [5]. It begs the question, which branch of scientific specialism would he prefer us to trust in analysing the state of the Earth’s climate? Dentists?

James goes on to describe the Intergovernmental Panel on Climate Change (IPCC) as “an unfailing source of alarmist propaganda…”, following up that they have somehow backtracked on their assessment of the global impacts that we can expect from a hotter planet. The truth could not be further away. The past few months has seen IPCC lead authors stating that we are on track for a global average of 4C rise in temperature by the end of century that will cause resource scarcity, increased conflict and sea level rise to name but a few outcomes [6]. He then goes on to state, “the emphasis had clearly shifted from mitigation to adaptation.” There is an element of truth to this but not because the problems we face are any less dangerous (as he implies). It is rather that the political and corporate will does not exist to take the necessary precautionary action. Therefore the world population at large are forced into the only response available: try to adapt.

But the change is happening and in the US we see a huge willingness by the Obama administration to show courage in squaring up to this very real issue [7]. With wildfires, drought, incredible sub-zero conditions and dangerous hurricanes as Sandy becoming a real threat to the wellbeing of the nation, it is sad that the likes of Clive James wish to remain in a silo of ignorance. Many of the poorer nations around the world are feeling the dire effects of manmade climate change, with low-lying islands and coastal areas facing direct threats from rising sea levels and extreme weather. To them, the idle jokes and mass media wit of a has-been like James would sound galling if ever they heard it [8,9].

From this point on James’s mask is off as he invokes the memory of the famed non-scandal tagged “climategate” by the media, representing vested business interests, propagating similar myths as James himself [10]. The inquiry that followed the non-scandal exonerated all those scientists whose emails were illegally hacked and misrepresented to the press to discredit their work. But the damage was done. The most important conversation we needed to have in 2009 (James says it was 2007 but that is incorrect) was dropped from the agenda altogether. That itself will be seen as a far greater scandal in the years to come [11]. It seems odd that our “mass media” expert was unable to decipher the truth from the loud shrills of tabloid mania that scoffed at innocent men.

Although I was compelled to smile at James’s peculiar rant against something he can’t seem to grasp despite mountains of evidence, his case against Malthus, climate change and associated risks, do carry an undertone of sadness. For James is not inheriting the Earth, he is bequeathing it to future generations and it is in a terrible state. To shrug and insinuate that the problems we face collectively, as a result of the mistakes made in the preceding decades, are just an illusion, is disrespectful and ignorant.

Clive James’s appraisal of ‘Malthus: The Life and Legacies of an Untimely Prophet’ [12] seems to fall away somewhere in this piece of writing. But between the lines of his misty views, he has done us some service. His message is clear but our reading of it should be clearer: the book is likely to be a very good insight and analysis of a man who, over 200 years ago, diagnosed the problem that we today are facing: population really does matter!

UK Shale Extraction Series - Part 1

Earlier this year I heard Prof. Mike Bradshaw speaking on #Shale #Gas extraction at the Royal Geographic Society (#RGS).

His talk was so impressive and dispelled so many myths put forward by the government that I contacted him and filmed an hour long discussion of all the points he made from an independent perspective. This is the first in a series of clips that we'll be releasing.
