“Demand carbon dioxide data” says Hans Rosling to open data advocates at OKFestival

September 21, 2012 in Data Journalism, Events, Featured, OKFest, Open Data, Talks

Gapminder is one of the best known examples of a project which uses open data to improve public understanding of big global issues and trends.

Yesterday Gapminder Founder Hans Rosling, who is also on the Open Knowledge Foundation’s Advisory Board, gave a spectacular keynote talk at OKFestival, for which he received a standing ovation.

In classic Rosling style he started out debunking myths surrounding international development trends – including a special demonstration using toilet rolls to illustrate population growth.

He spoke about the importance of story-telling and giving context and meaning to data through accompanying interpretation and analysis:

The old west has a toxic combination of ignorance and arrogance about the world. You can do very little with only open data, you can do very little with only info vis, but these are two really good tools. To this you have to add telling stories and telling facts.

He went on to give some background on the development of the Gapminder project, which came out of classes he taught using UNICEF’s State of the World’s Children charts, which he said his students didn’t like to work with:

Trying to think of a better way to challenge their misconceptions about development trends, he came up with the idea of the bubble chart:

How long did it take to invent the bubble chart? It took one second. I know exactly where I was standing in the hallway that evening after a lecture when I said ‘I’ll make each country a bubble’. ‘Colour is continent, size is population and I’ll put money on one axis and health on the other.’ Ten years to prepare, twenty years to develop, one second to get the idea. I had a lot of ideas that didn’t bring me any fame at all.

He did his first mockups using Excel and StatView, which he photocopied onto overhead projector transparencies and coloured in by hand.

Within 12 hours, he was lecturing using the new chart. He advised others doing open data projects:

Don’t talk about what you should do, just mock up and do it very very fast!

With help from a developer he had a first static version of the project. Over the following decades his son Ola Rosling helped him transform this into the fully fledged interactive explorer that Gapminder is today.

He went on to give an entertaining analysis of international financial trends by commenting on a photo of world leaders at the first G20 meeting in 2008 – again demonstrating that improving data literacy need not be a high tech affair.

He concluded by urging open data advocates to “demand carbon dioxide data”, saying that every day he has been monitoring the shocking speed at which the polar ice caps have been melting this summer.

While OECD and other international institutions hold CO2 data, much of this is not public or behind a paywall. “Let’s go there and liberate it!” he said, suggesting that we need a “data driven discussion of energy and resources”. While there have been numerous CO2 related applications and services about individual behaviour and lifestyle choices, he appealed to app developers: “Don’t do only small apps, do apps for the world”.

You can watch the full talk from around minute 00:34 from the live stream recording.

    OKFN et al,

    First, thanks for putting on such a tremendous conference, which obviously entailed a tremendous amount of work on your part, which I deeply appreciate. And thanks to Prof. Rosling for an enjoyable and inspiring presentation on Thursday evening.

    I want to correct one serious misconception from Thursday night regarding the availability of GHG emissions data. This is not something that countries have been keeping locked up, as was suggested. Countries have been reporting GHG emissions on a yearly basis in great detail to the UN Framework Convention on Climate Change since at least the signing of the Kyoto Protocol back in 1997. Currently there is very detailed data for all 6 major gases and detailed sector data as well, for every Annex I (i.e., OECD) country from 1990-2010. These reports form the basis for, among other things, the Kyoto Protocol and the emissions trading system currently in operation in the EU.

    Here is the link: http://unfccc.int/ghg_data/ghg_data_unfccc/items/4146.php

    Developing country emissions reports are more sparse (long story about the history of the Kyoto Protocol omitted), but they are also public. But CO2 emissions estimates are available from the US Department of Energy, currently through 2010. The International Energy Agency also has good international data, but the latest is behind a paywall (the World Bank publishes some of these in our open data catalog but with a time lag).

    Unfortunately, while the data are public, the UNFCCC data interface is horrid, and they are not as easy to access as they should be. The World Resources Institute’s Climate Analysis Indicators Tool (for which I was once the project manager) made these data much easier to access (for free), but unfortunately it appears the project has been indefinitely discontinued. I have half a mind to scrape the UNFCCC site and compile these data myself :)

    I would also respectfully but strongly disagree with Rosling on his assertion that what we need to solve climate change is more data. I worked on climate change for almost eight years. There is no lack of data, nor is there a lack of solutions. But we do need people to wake up to how serious the situation is. We need is better understanding of the data we already have, along with much stronger sense of public urgency, and the political will to make tough choices.
