Teachers often make subjective errors in assigning grades, due to things like time of bed bias and urban road rage effects. We all have been treated unfairly by teachers at one time or other, and it seems only fair to allow kids to adjust the raw grade data to more accurately reflect their true standing.
That way, kids can achieve the necessary grades to obtain their long-term objectives. Even if they don’t know jack shit about anything.
Paging Hansen. A full week between 127 and 134F – when CO2 was very low. Isn’t that impossible?

Romm says that everything melts at 113F, so things must have been a real mess in 1913.
Damien Biggs says:
I’m not sure exactly what argument you’re trying to make.
Records by their very definition only go upwards.
This line
There were twice as many daily all-time high temperature records set or tied during the 1930s as in the 2000sdoesn’t actually mean that the 30s were warmers than the 2000s! If Septemer 20th 1931 set an all time record of 120 degrees then 120 degrees on September 20th 2005 wouldn’t break that record. If you’re skeptical about global warming surely it would be better to present data that shows that previous decades were actually warmer.
Had I actually used the algorithm Damien claims I did, the graph would look like this. Every day at every station would have been a record in the first year.
A little thought before posting can be a good thing.
Romm and Masters keep touting the ratio of record maximums to record minimums this summer, but their numbers are both lower than 1936, and hugely skewed by a large number of newer stations which had no records from the 1930s. Not to mention UHI – which keeps recent nighttime temperatures up.
Here are some legitimate numbers from 1936, which use only the USHCN stations that have 80+ year long databases.
June 1936 TMax/Tmin = 18 / 1
July 1936 TMax/Tmin = 19 / 1
August 1936 TMax/Tmin = 14 / 1
I won’t be able to do any analysis of the 2012 numbers until USHCN releases them next year, but they won’t be anywhere close to 1936.
The summer of 1936 was much hotter than the summers of 2011 or 2012. Hansen is a disgrace to NASA and science in general.

Time of observation bias can not affect record high temperatures.
The forecast for Meeker on August 10, 2012 is twenty-two degrees cooler than 1936.

August 1936 was spectacularly hot in much of the central and eastern US, but it isn’t happening in 2012. Their strategy of pouring on the lies during hot weather has hit a brick wall.
You can’t make this stuff up. He claims that the weather is the most extreme in 10,000 years based on a baseline of “the last few decades”

What a brazen liar this man is. He wrote the exact opposite ten years ago.
Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath.
There were twice as many daily all-time high temperature records set or tied during the 1930s as in the 2000s, for USHCN stations which were operational during both decades. That is why he doesn’t start his baseline until the 1950s.
Perhaps the 1930s was more than 10,000 years ago?
Barring a huge change in the weather, the map below shows the minimum possible extent for 2012 vs. 2007
Green is 2012 and red is 2007. This is based on current ice thickness and temperature forecasts. Chances are that 2012 will finish larger than what I showed, because there is a lot of MYI in the Chukchi Sea which is not likely to melt out.
The only thing which could change this would be very strong southerly winds, like those which occurred in late summer 2007.
