Slide 60
NJclimate.org Summing up: Be it weather moodiness or long-term
climate personality changes, a dull moment is rare to find. There
is abundant evidence that the atmosphere, oceans and continents are
primed to produce even more action, more variability, more change
in the decades ahead. Continued vigilance is required to monitor,
understand and predict the future behavior of the climate
system.
