If you heard that a temperature record had been set, how long would you expect that temperature to hold: 1 hour, 30 minutes, 10 minutes,1 minute? In 2008, Lin and Hubbard argued it should be 7 minutes, that even a 5 minute averaging was not long enough to avoid some warming bias in maximums and cooling bias in minimals. 1
No so in Australia! There the Bureau of Meteorology (BOM) will write it in Australia's record books even if the heat lasts one second, and if the temperature a minute before was more than a whole degree cooler. 2
