I put these charts up for the seasons and the annual for our region so you folks talking of the changes can get a glimpse of what has been, and what things look like now in comparison. I think we do a great disservice to the observers of the past by calling their work suspect. Then and now, they all do their best. It's pretty easy to point to this issue or that to discredit the data that has been collected, but the record in the US is the best in the world. The CRN network is probably the most pristine we have at the moment, but is very short.
These are a fair representation of the last 200 years of our region. It'll be awesome to see how it works out over time. I think I have a few more years to go.
