I haven't written anything about colourblindness for a while. This graph though is very very hard for me to interpret, but due to the slightly darker line denoting the border of dry and wet I can work it out. Ok Thanks Daniel.

I had a look at a climate zone diagram which is hard to decipher if you are colorblind. And when I see you diagram I have the same problem: I don't really see any difference in the areas. Maybe you would like to try Protan Tools (see my article: <a href="http://www.colblindor.com/2007/03/13/color-translation-readable-diagrams-for-the-colorblind/" rel="nofollow">Color Translation — Readable Diagrams for the Colorblind</a>), which makes the diagram definitely more readable to me. By the way, my blog Colblindor has now its own url. Maybe you like to update your blog link list. - Daniel Steve, after some absence I came back for a visit to your blog and discovered, that we just recently wrote about the same topic “climate”, even though from a complete different viewpoint.

Nor am I insisting that there will be no change to rainfall with climate change in south eastern Australia in the future. Merely that the historical record shows little evidence for it having already occurred. I do however think there has been a tendency to view the high levels of rainfall recieved in the 50's and 70's in particular as "normal" and the low rainfall of other periods as abnormal and this has biased our views on what to expect. In addition mean rainfall is higher than median rainfall. The big years skew the average upwards. Most years we should expect less than average rainfall.
