This past week I was fortunate enough to see a presentation given by David MacKay, Chief Scientific Advisor at the Department of Energy & Climate Change (DECC). Author of the acclaimed book Sustainable Energy – without the hot air (available for free online), Prof MacKay is a font of knowledge and scientific rigour when it comes to the hard questions of climate change and the options available at personal, collective and government policy levels.
Running through some of the numbers is always an eye-opening exercise, and there are plenty to mull over in the text of his book. There were some rather humbling views for the more environmentally aware on just what it would take to power a country such as the UK with biofuels or solar panels using current technology (answer: an amount of physical space the size of small countries, not to mention the cost and infrastructure requirements), as well as a call for politicians and the media to operate off a numbers basis rather than a rhetorical one. The real purpose of the lecture, however, was to present a rather fantastic tool which has been developed by DECC to help people visualise and contemplate different possibilities to meet carbon reduction quotas by 2050.
The 2050 Pathways calculator is an impressive piece of open-source kit, allowing you to prioritise different avenues for both energy consumption and supply in an attempt to meet current emission reduction targets – “showing the benefits, costs and trade-offs of different versions of the future“. There’s an impressive amount of data underlying the tool, and thankfully plenty of explanatory links for every item included. As an educational tool on climate change and energy policy it is truly excellent – the number of conversations you could build off of the backs of choices made is practically countless. Unfortunately it does lead to a rather morose realisation that so much needs to be achieved, developed and implemented to even get close to the emissions quotas that you find yourself wondering just how possible it is at all…
Climate change will almost certainly be a devastating component of the 21st century, and the various possible energy crises will lead to additional conflict and destruction on top of that. The situation looks very grim, and that leads to the kind of collective buck-passing and thumb-twaddling that only exacerbates the problem. However, the calculator at least provides us with some data-driven responses that should focus our individual thinking and also educate us in the broader policy decisions in order to encourage us to participate and enter this important societal conversation.
Numbers-driven approaches allow us to circumvent some of the passionate, albeit often useless, rhetoric in order to replace it with more effective means of combating the problem. Prof MacKay gave the somewhat humorous example of a recent government poster campaign that encouraged everybody to make sure their phone chargers, and other such appliances, were switched off at the wall when not in use. This makes for a great poster design, and very easy feel-good wins for us all as we switch off those power points. In the end, the difference per day was about the equivalent of 1 second of driving a car…underwhelming to say the least.
We’re better off encouraging people to walk or ride to the shops rather than drive or, as Prof MacKay gave as an example, decrease the temperatures of our homes by a relatively small amount. When you use the calculator and see the impact that an overall decrease in average home temperatures has over and above almost any other option – it makes it incredibly easy to put on that jumper and turn down the thermostat.
The calculator also makes you think more carefully about blanket statements such as ‘we should just put solar panels on every roof’ or ‘nuclear energy will solve all our problems!’. By providing you with the resources to see the true impact of each approach, both in terms of carbon reduction but also cost, space and innovation requirements, the discussion immediately becomes more nuanced and the weight of decisions immediately more visceral.
There’s a great example here of the importance of data-visualisation, and I’ve discussed before how important such an approach will be over the coming decades. Our capacity to collect, share and analyse data is growing exponentially; but it is very difficult for people to engage with findings unless they are accessible and help clarify things like scale (millions, billions, trillions…there’s really quite a big difference!) and display things in relation to one another.
The kinds of interactive, dynamic data-visualisation represented by the 2050 Pathways calculator should be applauded for bringing us into contact with the very difficult policy decisions that must be made over the coming decade and beyond in such an accessible and impacting manner.
Conversations change society, and by enabling people to enter into conversations on climate change with insight and a solid foundation of the options available is certainly a vital aspect of the overall path to overcoming and/or dealing with climate change that we are going to have to walk together. Have a play around with the 2050 Pathways calculator and share it with your friends, see what plans they come up with and the discussions that emerge as you try and balance one set of sacrifices over another; with the entire process occurring upon the backdrop of a possibly cataclysmic shift in how we relate to the ecosystem that we rely so very much upon.

You thought I’d forget about you in January, didn’t you? We’re certainly cutting it fine, but since the new year must bring some new predictions here are nine areas that I think will see important milestones or changes in public sentiment in 2013:


The first thing I noticed when compared to the previous exhibition
The sections on disability were impacting and empathetic, with a whole section on the damage caused by widespread use of thalidomide during a four year period between 1958-1962 and the subsequent birth defects that followed. The showing of Matthew Barney’s surrealist film
Instead they are relegated to a dark corner, one in which the words of those speaking can’t be heard clearly enough and for most visitors are likely not part of their experience of the exhibition at all. Thankfully the very well produced programme gives their positions in full, and for just £1 you can’t possibly ask for a better piece of the exhibition to take away with you.


If I had to choose a favourite post, most of the time I’m going to choose my initial review of Radio Free Albemuth. Primarily because of the absolutely surreal experience that I had on the day (given in full detail in the post), but also because it opened up a dialogue with the film’s director and producer which a year later meant that I was able to meet them in person to discuss the movie and also score an interview for the blog. Being such a huge fan of Philip K Dick, I felt priviliged and honoured to be part of the roll-out of this film in whatever small way. Here’s hoping it gets a wider release very soon!
There’s something about the world of hackers, cyberpunks and online activists that is so intriguing that it has always been a topic of great interest to me. Of course the reality rarely matches the myth, but I thought it was important to try and clear up some misconceptions that were going around in the press at the time whilst also highlighting why people of this persuasion – whether you agree with their methods or not – have a very important role to play in the 21st century.
Part of what I love about writing the blog is that it encourages me to get out there and go to exhibitions or other events that are relevant and interesting. This post sees me playing around with ideas surrounding the anthropomorphic nature of our view of sentience, and I enjoy it because of its philosophical depth. Like many of the posts on the site, it’s basically a stream-of-consciousness piece…which means that it trades off a certain degree of structure and academic riguour in an attempt to access those areas of our minds that rest just on the edge of what we can grasp hold of.
It’s not every day that you get to sit in front of someone who has walked on the surface of the Moon. Today I was given just such an opportunity, a conversation with Buzz Aldrin which took place at the newly refurbished House of St Barnabas – which for the Olympics madness has been knighted as
With the
How we treat the extension of humanity beyond planet Earth will dictate the very philosophical foundations that we build our future social identity around. Yes, it might be true in the current socio-economic context that many of the things we dream of cannot be achieved without privatisation of one kind or another – but at what cost, then, will our dreams be fulfilled?
Our exploration of the solar system and beyond should be seen as the best chance we have at overcoming our biological nature for territorialism, hostility and competition; replacing it instead with a mode of action that builds upon our capacity for empathy, compassion and collective wellbeing. Commercial enterprise will definitely play an important role in getting us to the point where we can spread our wings as a species and expand into a new destiny. We just need to ask ourselves what that destiny might look like, who will form it, and who will be the primary beneficiaries.
