Climatologists dispute (or should dispute) about a possible long-term and global temperature drift and its consequences on creatures -populations- on our planet. A plausible (model-based) scenario states that a little increase of ground-level energy generates very sensible effects on livings and lifes of creatures in general and humans in particular.
By abstracting a little bit, one could detect similarities in long-term drifting-phenomena of economies in developped countries. There is a slight difference however: instead of a noxious atmospheric positive drift, one observes an adverse dying-out of `back-ground energy'. This phenomenon is likely to magnify the impact of otherwise `normal' recessions and to put some serious pressure on `leaders'. In this context, the 2008-recession may not appear to be as `singular' as it is often claimed to be and we may expect recurring episodes with comparable magnitudes.
