So, the record, while incomplete, is pretty good. Do you have any evidence of this claim? Specifically, do you know where I can find the formula used to calculate the global temperature and the constituent temperature readings, locations and time/dates? Common sense says that such readings would be spotty at best and also that they would be incomparable between 1880 and 2014 but since they are comparing them I'm very curious of their methodology. EDIT OK I found what claims to be the source code of the software that massages the numbers here: http://data.giss.nasa.gov/gistemp/sources/ http://data.giss.nasa.gov/gistemp/sources/ EDIT2 OK I found the underlying data here: http://data.giss.nasa.gov/gistemp/station_data/ http://data.giss.nasa.gov/gistemp/station_data/ It's exactly what I thought. Hardly any of the stations go back to 1880 and the ones that do are unbelievably spotty with sometimes two years or more of missing data. Oh and they're apparently not even measurements - they're "reconstructions". And apparently they re-adjust these reconstructions all the time. (see http://www.americanthinker.com/blog/2012/09/nasas_rubber_ruler.html#ixzz27YZRxqIW http://www.americanthinker.com/blog/2012/09/nasas_rubber_rul...) The environment would be much better off if we stopped pretending we know things we don't and just agree that it is stupid to squander a finite resource like fossil fuels and start conserving it.
