Which divided by 3 billion would be $5.77/passenger in 2010, $2.50/passenger in 2011, $2.03/passenger in 2012, $3.53/passenger in 2013, and $6/passenger in 2014. What did you think I meant by “of the order of $5”?
Yes, we agree on the numbers, we're just throwing connotations at each other :-)
$5 is a small number so you're pointing to this. $somebillions is a large number and I'm pointing to that.
I am still pretty sure commercial aviation is perfectly viable economically, it's just that certain peculiarities of the business make it hard to make lots of money in it. However it's not going anywhere and, say, doubling the fuel prices will not make it go away either.
Note: Please see this post of mine for more on the project, my sources, and potential sources for bias.
I have written a couple of blog posts on my understanding of climate forecasting, climate change, and the Anthropogenic Global Warming (AGW) hypothesis (here and here). I also laid down the sources I was using to inform myself here.
I think one question that a number of readers may have had is: given my lack of knowledge (and unwillingness to undertake extensive study) of the subject, why am I investigating it at all, rather than relying on the expert consensus, as documented by the IPCC that, even if we're not sure is correct, is still the best bet humanity has for getting things right? I intend to elaborate on the reasons for taking a closer look at the matter, while still refraining from making the study of atmospheric science a full-time goal, in a future post.
Right now, I'm curious to hear how you formed your views on climate change. In particular, I'm interested in answers to questions such as these (not necessarily answers to all of them, or even to only these questions).
