Unloading Hansen's 'Climate Dice'

By Chip Knappenberger -- September 24, 2012
“Today’s temperature ‘extremes’ are simply yesterday’s extremes warmed up a bit, partly from the heat-island effect. But they are not new events…. Hansen’s push on weather extremes is another case where the level of alarm is disproportionate to the level of impact.” 

Today’s temperature “extremes” are simply yesterday’s extremes warmed up a bit, partly from the heat-island effect. But they are not new events where none existed prior.

This distinction is neither subtle nor unimportant. When it comes to temperatures, yesterday’s extremes warmed up offer less of a surprise (and hence a greater ease of adaptability) than if a new crop of extreme events suddenly sprung up out of nowhere to catch us unprepared.

But such a distinction is not made prominently evident in the latest work by NASA’s James Hansen—and even less so in the accompanying media coverage (including that instigated by Hansen himself).
