Emanuel, Prinn, Lindzen Debate CRU-Hack at MIT

Meteorology (EAPS in MIT-speak) professors Kerry Emanuel, Ronald Prinn, and Richard Lindzen, discussed the hacked emails (widely pimped as "ClimateGate") from the Climate Research Unit of the University of East Anglia with two political scientists on December 10.

What we have here are thousands of emails collectively showing scientists hard at work, trying to figure out the meaning of evidence that confronts them. Among a few messages, there are a few lines showing the human failings of a few scientists…
. . .things that are unethical and in many cases illegal . . . willingness to destroy data rather than release it . . . bad things going on . . . elite hysteria . . . devastating for popular support for science . . . scandals, cheating and arguments . . . bizarre changes [to the data] . . . The public is being thrown catastrophes.
My view of the risk is that we have no other planet to retreat to if we are wrong.

Stores Seen Surviving Super Saturday Storm

Dec. 22 Update: CNBC finds today that nationwide retail sales have increased, despite the weather:

Original post:
After pounding the Washington/Baltimore area with record-setting snowfall, the Super Saturday storm left massive amounts of snow on parts of New Jersey, Pennsylvania, Connecticut and Long Island before departing out to sea. Nevertheless, a report from Bloomberg today indicates that last-minute shopping in the remaining days before Christmas may make up for lost sales over the weekend. Despite the reputation of "Black Friday", the maximum day for retail sales is usually "Super Saturday" on the weekend before Christmas. Overall, the 10 days before the holiday make up 40% of sales for the months of November and December, according to Bloomberg.

The NYT, on the other hand, was more cautious, pointing out that the region affected by the storm accounts for about 25% of a typical national retailer's total sales:

The FT reported:

Some more records set by the storm:

On Long Island, the 26.3" of snow at the National Weather Service office in Upton set a new single storm record, breaking the old record of 23.0" in the blizzard of 1978.

Providence, RI set a new all-time December daily snowfall record with 14.3".

The storm total of 23.2" at Philadelphia is the second highest all-time storm total. The record is 30.7" in the blizzard of January 1996.

Many locations set individual daily records for December 19 or 20.
