Continuing on the dust bowl topic which Dr. William Gray seems to have discounted, I added a few hydrology plots to my yahoo photos website to show how severe and widespread the early-mid 1930s drought was.
- Hydro at:
I included plots showing Mississippi River streamflow (1874-2004), Lake Michigan-Huron (1918-2005) and Devils Lake ND (1830-2006).
Contributing drainage area for the Mississippi River is 85,600 square miles at Clinton, IA and 1,140,500 square miles at Vicksburg, MS.
I think the Clinton, IA plot is especially interesting, showing that conditions preceding 1940s/1970s cooling was a drying trend, while condition preceding the current is a wetting trend.
That's the opposite direction, and I figure to be counter to what Dr. Gray the pattern recognizer would expect if cooling would return. No going to happen the way he thinks, by the patterns I see.
