Things are going to get worse...

Table 2 in the Working Group I Summary for Policy Makers paints a grim, one could even say, Stern like picture. As in the third law of thermodynamics things are scheduled to get worse. This appears not to have been much commented on, but is worth paying attention to. Now the devil may care will ask, if we are not so certain about attribution of current climate change (see the second and third column) how can we be more certain about what will happen in the future :( see last column): The answer, of course, is that the changes are getting bigger as the forcing grow.

Phenomenon and direction of trend	Likelihood that trend occurred in late 20th century (typically post 1960)	Likelihood of a human contribution to observed trend	Likelihood of future trends based on projections for the 21st century using SRES scenarios
Warmer and fewer cold days and nights over most land areas	Very likely	Likely	Virtually certain
Warmer and more frequent hot days and nights over most land areas	Very likely	Likely (nights)	Virtually certain
Warm spells/heat waves. Frequency increases over most land areas	Likely	More likely than not	Very likely
Heavy precipitation events. Frequency (or proportion of total rainfall from heavy falls) increases over most areas	Likely	More likely than not	Very likely
Area affected by droughts increases	Likely in many regions since 1970s	More likely than not	Likely
Intense tropical cyclone activity increases	Likely in many regions since 1970s	More likely than not	Likely
Increased incidence of extreme high sea level (excludes tsunamis)	Likely	More likely than not	Likely
