Sep. 17--The case implicating humans' role in climate change was bolstered this week by another fingerprint, this one on water vapor in the atmosphere.
Scientists used computer models that simulate the climate to show that the rise in water vapor could not have been caused by natural climate fluctuations alone.
But when man-made greenhouse-gas emissions are included in the models, the resulting atmospheric water vapor increases are very close to those actually observed over the past two decades.
"It's disquieting that the evidence is mounting that we're influencing the climate now," said Lawrence Livermore Lab ...
