Important information regarding the recent AMS power outage.

The transformer that provides electricity to the AMS building in Providence went down on Sunday, April 22. The restoration of our email, website, AMS Bookstore and other systems is almost complete. We are currently running on a generator but overnight a new transformer should be hooked up and (fingers crossed) we should be fine by 8:00 (EDT) Wednesday morning. This issue has affected selected phones, which should be repaired by the end of today. No email was lost, although the accumulated messages are only just now being delivered so you should expect some delay.

Thanks for your patience.

"Possible or probable?," by Myles R. Allen. Nature, 18 September 2003, page242.

Uncertainty in climate models results in a range of possible outcomes thatcan't all be planned for. The climate-research community is attempting toassign probabilities to climate forecasting so that preparations can be madefor the more realistic scenarios. Toward that end, the community wants toassemble information from the simulations of various models. Care must betaken when searching for a representative sample of models because models canbe very similar. Also the models often operate on the same data set so thatassigning weights to the selected models isn't a straightforward processeither. So many climate simulations are needed that climate researchers arenow using idle desktop processing time (information here).
