so you admit that the .74 degree temp change in 3 years is meaningless? If 150 years isn't enough, then 3 years is most certainly not enough, so why did you post the article?
It's more relevant than 150 out of 6 billion, that's for sure.

It proves that the fanatics are wrong, once again.

It proves NOTHING. How is 3 out of 6 billion more relevant than 150 out of 6 billion? Honestly, every time you post an article that involves science or statistics, you end up looking like an idiot. You are never able to explain what it means or why it matters. You repeat and repeat and repeat your self, saying NOTHING each time!

lol....
The reliable instrumental record only goes back 150 years in the CRU analysis, 125 in the NASA analysis. This is a simple fact that we are stuck with. 2005 was the warmest year recorded in that period according to NASA, a very close second according to CRU. Because of this limit, it is not enough to say today that these are the warmest years since 150 years ago, rather one should say 'at least': 1998 and 2005 are the warmest two years in at least the last 150.

But there is another direct measurement record available that can tell us things about temperature over the last 500 years, and that is borehole measurements. This involves drilling a deep hole and measuring the temperature of the earth at various depths. It gives us information about century-scale temperature trends, as warmer or cooler pulses from long term surface changes propagate down through the crust.
Using this method we can see that temperatures have not been consistently this high as far back as this method allows us to look. This way of inferring surface temperatures does smooth out yearly fluctuations and even short term trends, so we can not know anything directly about individual years. But given the observable range of inter-annual variations recorded over the last century, it is quite reasonable to rule out single years or even decades being far enough above the baseline to rival today. Using this record, we can reasonably conclude that it is warmer now than any time in at least the last 500 years.

It is possible to make reconstructions of temperature much further back, using what are called proxy data. These include things like tree rings, ocean sediment, coral growth, layers in stalagmites, and others. The reconstructions available are all slightly different and provide sometimes more and sometimes less global versus regional coverage over the last one or two thousand years. Note: this covers what is often referred to as the Medieval Warm Period. As noted, all these reconstructions are different, but ...
... they all show some similar patterns of temperature change over the last several centuries. Most striking is the fact that each record reveals that the 20th century is the warmest of the entire record, and that warming was most dramatic after 1920.
I know down south they're having a heat wave, but up here in Pa I haven't put in the air conditioners yet. When its only in the upper 70s to low 80s a window fan is good enough.

Sorry, 1998 and 2005 are not the warmest years on record. Hansen's work has already been proven to be incorrect.
Steve McIntyre posted this data from NASA's newly published data set from Goddard Institute of Space Studies (GISS) These numbers represent deviation from the mean temperature calculated from temperature measurement stations throughout the USA.
According to the new data published by NASA, 1998 is no longer the hottest year ever. 1934 is.
Four of the top 10 years of US CONUS high temperature deviations are now from the 1930s: 1934, 1931, 1938 and 1939, while only 3 of the top 10 are from the last 10 years (1998, 2006, 1999). Several years (2000, 2002, 2003, 2004) fell well down the leaderboard, behind even 1900. (World rankings of temperature are calculated separately.)

Well, we know for sure that temperatures were much, much hotter in this planets history.
To draw a conclusion based on 150 years is the epitome of stupidity.
