WB, I guess you didn't see Akichow's wink smiley
. I think what she meant is that the more years of drought we experience, the more it seems "normal." This one we're in now is on the verge of being historically rare, but long droughts in the western US are nothing new.
From NOAA Paleoclimatology: The paleoclimatic record also indicates that droughts of a much greater duration than any in 20th century have occurred in parts of North American as recently as 500 years ago. These data indicate that we should be aware of the possibility of such droughts occurring in the future as well.
The climate change models tend to diverge on this one, as the CO2 levels rise, we may get more rain from warmer oceans just as likely as more drought. What's for sure is we'll have more thermal energy in our atmosphere and oceans, so extremes in either direction are more likely. The pendulum will probably swing like it does now, but a little further in both directions from longer droughts to more severe floods.
