Last week I went to the London showing of Vice President Al Gore’s Climate Reality Project - it was one of 24 consecutive presentations held around the world on the 15th of September. There was a lot to look forward to in attending this, particularly to see how Mr Gore would respond to the troubling attacks on the science currently seen in some political debates and the continued challenge to carbon pricing policy in countries like Australia. Some have argued that we are at a crossroads in climate policy, with richer nations seemingly deciding that they will wing it and let the physics play out over the coming century (for a thoughtful piece on this click here).

 From a personal perspective and for context, I found An Inconvenient Truth to be a remarkable film and I was very pleased to be able to attend an Al Gore training session myself – and one that he personally delivered for a day in Cambridge, England. I have even used some of the material in my own presentations, which of course was the quid pro quo for attending the training. But it is good material and although I differ with Mr Gore on the way he interpreted some of the paleoclimate record, his overall message was solid.

This time though, I was disappointed and I am even more disappointed that this was the case. The core section of the presentation focused on extreme weather events and pretty much blamed them all on the long term change in the climate that is seemingly underway. By chance that same afternoon, I had listened in to an MIT web cast on exactly the same subject – extreme weather events. For me the contrast between the two was a concern. Although both presentations explained the observable shifts taking place in the global hydrological cycle and both showed the disturbing trend in measurements such as atmospheric humidity, Mr Gore then went straight from that to the remarkable cascade of disasters that have unfolded over the past 12 months. MIT did not, nor would their presenter be drawn on it even when pressed on the subject by one of the listeners. Rather, MIT focused on the rising global temperature and humidity and declining ice coverage and showed real measurements which illustrated how warmer ocean surface temperatures might lead to more intense hurricane activity.

Included within the Climate Reality slideshow were the Pakistan floods, the Australian floods and bush fires, the US floods from North Dakota to Nashville and down the Mississippi / Missouri River system, mud slides in Colombia and the Texas drought. These have been (and continue to be) awful events and they are illustrative of some of the possible impacts of a warmer, moister atmosphere, but they are not necessarily caused by this. In fact, 1974 also suffered a string of such disasters and both it and 2010/11 had another thing in common, an intense La Nina (1973-1975) in the Pacific. Record Australian, Brazilian, Colombian and Bangladeshi floods all featured in 1974, together with a super-outbreak of tornadoes in the United States. Somalia suffered an intense drought in that period as did the central USSR.

I don’t want to undermine the efforts of Mr Gore, but only point out that he is going to have to do better to communicate his important message. In this era of soundbites and media savvy politicians it will be all too easy to take shots at this new work. The much longer but more rigorous MIT approach is where we should be, despite the huge challenge of successfully communicating uncertainty and atmospheric chemistry to a global audience. Let’s not forget that a much more complex atmospheric chemistry issue (CFCs and the ozone layer) was communicated in the 1980’s.

In the last section of the presentation Mr Gore poured scorn on those who have challenged the science. This included special interest lobby groups (oil companies among them) and a number of well known political figures. I can’t agree with the statements made by some leading politicians who dispute the work of the scientific community, but direct attack isn’t the answer here, despite the huge temptation to do so. Nor is it the reality that all industry lobby groups are seeking to undermine the science. While some groups have been less than helpful and others have just displayed ignorance, many, many business groups have positively contributed to the development of a way forward. In the US, USCAP did a remarkable job in helping craft and then supporting the Waxman-Markey bill. Globally, some 150 companies (many of which are Fortune 500) belong to the International Emissions Trading Association (IETA) and actively press for cap-and-trade approaches at national and regional level. Similar work is done in the WBCSD, the UK and EU Corporate Leaders Groups on Climate Change, the European Round Table of Industrialists, just to name a few. Sure, the businesses in these groups might fight their corner and will have no qualms about challenging issues such as allowance allocation in trading systems, but that is in the nature of reaching agreement.

The Climate Reality Project is an important next step, but at the moment it feels like a somewhat inconvenient one. The challenge back is the right thing to do, but the debate needs to be moved to a higher level, out of the trenches that currently seem to be occupied by many. This is an issue that will be around for the next 100 years and possibly much longer. We will all be too exhausted to even think about a true response if the current level of rancor is simply maintained.
