Global warming followup

I posted recently on global warming guessing here.

Since then, another stellar article has come out indicating that there is a significant new tool for climate change modeling.  Try to follow the trail of made-up information and guesswork: the scientists here have guessed backwards about sea level changes to create hypothetical data.  They then indicate that this data is useful for modeling future climate change.  In other words, by drawing a line from a guess in the past through what we think we know about the present, we will be able to definitively state what the future will be like.  Given the certainty with which we can state the outlook and causes of this future, we should make state-mandated policies to control the effects we state this future will hold.

Sure, that much guesswork inspires confidence.
