We think we have done more than we have done and we haven’t understood how much we have to do. Hans Rosling
Hans Rosling is a Swedish medical doctor and statistician who is determined (in his own words) “to fight devastating ignorance with a fact-based worldview that everyone can understand”.
Here is a video of him giving a talk on September 28th, 2013 at a public forum that introduced the latest IPCC report. The meeting was hosted by the International Geosphere-Biosphere Programme in Stockholm.
During the talk he asks a couple of questions, one on how many more children there will be in the year 2100 compared to today and another on what percentage of world energy is produced by solar and wind. I was in the minority that got the first one correct, but only because I had already seen one of Rosling’s earlier talks. On the second question, I was among the majority that got the answer wrong. How will you do?
