So do you agree that using a proxy from a single location to represent global temperature is invalid or are you just going to continue to avoid answering the question. A simple yes or no will suffice

Do you agree that using surface station readings, heavily biased to the Northern Hemisphere, have no hope of calculating a GLOBAL temperature?

do yo prefer that Australian land surface temperatures are used lee?

what do you mean by "HEAVILY biased".

Provide some statistics and hard evidence or apologise and leave

well done though - well done on your disastrous partnership with Batman.

You will in tears in no time mate - well done

Well I guess if you arn't happy with measurements from well over 5,000 temperature stations then I'll take that as a "Yes". You agree that Ajax's graph using just one location in Greenland is discredited.

Do you agree the Southern Hemisphere with less than 12% of surface temperature stations are under represented in calculating a GLOBAL average temperature?

No I dont.
The ratio of northern hemisphere to southern hemisphere stations is irrelevant.
All that really matters is that there are enough stations in the southern hemisphere to give a reliable reading for that hemisphere.
674 stations is a lot more reliable than relying on a single ice core sample in a single location in Greenland.

your graph isnt clear batman. What is the x-axis time range? In what year does the data end? Where did you extract the data?

Apologise and retire to continue your weeping batman

The USA has the most weather stations out of all other nations.

Empirical readings from NOAA weather stations SHOW a cooling trend.

Ice core data is used to determine our past climate.

Therefore the ice core data observed from Greenland is valid for determining what went on in our history.

Both alarmists and skeptics accept it.

Unless you have some valid reason as to why these studies aren't relevant you haven't got a foot to stand on.

BTW that graph shows nine occurrences of global warming in the past 11000 years and not one of them correlate to what CO2 is doing.... Grin

Quote:

Showing from 200 to 11000 years ago, the subsequent graph is based on ice core data, readily visible in files hosted on the servers of the U.S. National Oceanic and Atmospheric Administration (NOAA):GISP 2 and EPICA Dome C

Don is a long retired Geology Professor from Western Washington University. The faculty was so affronted by this nonsense that they wrote a letter to the Bellingham Herald, where Easterbrook originally posted. I'll see if I can find the letter.

If you want an actual peer reviewed paper that provides a reconstruction of global temperatures for the past 10,000 years, the most recent work is Marcott et al. (2013, A Reconstruction of Regional and Global Temperature for the Past 11,300 Years, Science, Vol. 339 no. 6124 pp. 1198-1201.

There are other respectable peer reviewed studies such as Shakun et al.

Combining the data from these two studies plus Hadcrut 4 and a projection to 2100, this is what it looks like:
