Which side are you on, the "column" or the "row" side?
The video above is one person's argument about why we should respond to the possibility of Global Warming. Below is my brother's (a meteorologist, but NOT a freakin' "weather man"!) response to the video. He constructed a classic contingency 2x2 table, which we use often in scoring meteorological forecasts which are deterministic: no/yes (0 or 1), versus probabilistic values between 0 and 1. In his table, you have "correct forecasts", the lower left and the upper right. Forecast N, and verify N is the upper right. Forecast Y and verify Y is the lower left. In the upper left, you forecast Y and verify N. That is called a "false alarm". In the lower right, you forecast N and verify Y. That is called a "missed forecast". It is well known in meteorological circles that the penalty for a "miss" is much greater than the penalty for a "false alarm". For the latter, if you have many false alarms, you might end up with the ...
