There’s another excellent article at the oil drum http://www.theoildrum.com/...
regarding projected total world energy production (extended out to 2030), and the contribution of fossil fuels to that.
Note that 2030 is three years short of my general projection of 450ppm CO2 within 20 years (based on current trends) . . . but then this article suggests an even more substantial growth in CO2 (although it's unmentioned in the report) than I have been assuming, and neither account for probable “natural” releases of CO2 and Methane from sources in the warming Arctic (permafrost and clathrates).
It does not look very promising. Of course also missing from the report (along with CO2) is the possibility of “other” limits being reached . . . mass starvation, global economic collapse, world war or asteroid impact, any or all of them might happen . . . and that reducing world energy demand growth before 2030 arrives. On the bright side it is unlikely that sea level rise (which will be between 5 and 10 Centimeters by 2030) will be much of a bother . . . overall climate change impacts will far exceed the relatively minor loss of coastline within this time window. That said, it’s still probably best not to be considering either a beach house or river valley (floodplain) property as a long term investment or as something to pass on to the kids.
