The Goddard Institute of Space Studies (GISS) at NASA asserts that 2005 was even warmer, with an average global surface temperature of 14.77 degrees C, with the 1998 figure being 14.71 degrees C. A tropical El Ni?o contributed 0.2 degrees in 1998, but 2005 had no Ni?o effect.

However, the fourteen year period 1995-2008 included thirteen of the hottest years on record, the exception being 1996. The fundamental question is, 'Which factor is more significant? A spike on a chart representing a single year, or a longer trend line over a decade or more?

The Hadley Climate Centre in the UK isolated the calendar year 1998 as the hottest on record for aggregate atmospheric temperature.

RB the 1998 hypothesis has been discredited completely its only non scientist like Monckton or scientists with zero applicable experience like Bob Carter (a geologist) who peddle that rubbish
