Sorry, I was quoting numbers out of memory, so only a 23 billion
dollars gain is predicted :(

Indeed, there are countries that are likely to suffer a net loss as a
result of warming. I am not familiar with any credible (i.e. produced
by professional economists and published in economics journals)
estimates of the worldwide impact. It is important to note that the
regions most likely to gain are the arid and semiarid regions - the
primary mechanism of the beneficial effect of CO2 fertilization is the
reduction of transpiration from leaves. If there is a lot of CO2 in
the air, plants can absorb all they need while keeping their stomata
partially closed, which leads to less evaporation. So, surprisingly, a
lot of hot places will be better off too.

### I do not believe that nanotechnology will amount to anything
before the AI singularity. For saving the greatest number of people at
the lowest cost, see the Copenhagen Consensus
