I would say that my heir(s) will collect the winnings, but I fully expect medical progress will let me outpace death for quite some time.
"And what do we say to death?"
"Not today!"

However, having lived and read newspapers at the time, I remember the scare mongering, and specifically the mention of the "Marker Tree" in the Maldives, which were projected to to have significant areas under water by 2010, then 2020, now 2100 (spolier: it didn't happen https://uk.answers.yahoo.com/question/index?qid=201107180902...)
A quick googling cannot find the original predictions (days before the web ... go figure), but this interesting discussion http://johncarlosbaez.wordpress.com/2012/03/27/the-1990-ipcc... will give you an idea about the difference between 25 year old predictions and what actually happened.

I'm sure this is backed up by studies and references, and at the same time I am amused at the hubris of making this statement. It's a cheap prediction to make, given that it will be around 2070 before you can verify it - and how right it is depends on lack-of-catastrohpies (e.g. in 20 years we'll have an idea how the meltdown in Fukushima affects lifespan), same-rate-and-same-kind-and-availability of advances, etc.
And before you criticize me for being "anti-sciece" - I am not, and unlike a lot of other assertions, this might technically be science (I haven't reviewed the source material) - however, it is not useful science because it may take 70 years to falsify.
Furthermore, a lot of -- perhaps most -- extrapolations of past trends had been wrong. At the time of Wallace & Darwin it was "scientifically" extrapolated that food will only grow linearly. And in 1980 climate studies had shown that if we don't do anything (and we didn't) by 2000 quite a few coastal cities will be underwater. If I wasn't anonymous, I'd place a long bet that the data crunching that led to this prediction will turn out to be complete rubish.
