You mean this one?

See how 2010 was the previous high? The difference there is 2 one hundredths of a degree between 2010 and 2014.
Now here's what Dr. Whitehouse said in the explanation.
$1:
In reality of course it is no record at all as the error of the measurements is about +/- 0.1 deg C showing NasaGiss’ statement to go against the normal treatment of observational data and its errors. Talk of a record is therefore scientifically and statistically meaningless.
http://www.thegwpf.com/2014-global-temp ... ther-year/So he's saying you would need at least 1 tenth of a degree difference to have a statistically meaningful difference. There is only 2 100ths of a degree difference.
So when Zip says...

what is significant about 2014 being so warm
How warm?
2 one hundredths of a degree. That's how warm.
Is there any convincing reason to believe global temperatures can even be measured with that kind of accuracy?
Yes it was warm this year relative to the last thousand years. We're sitting on a peak.
But between 1998 and 2014, hundredths of a degree guesstimates are not a trend. We have been sitting in a climate pause for 17 to 18 years without any statistically significant rise in temperatures.
According to predictions of a supposedly inevitable global warming crisis, that wasn't supposed to happen. Nevertheless we continue to wait for the end of this climate pause that isn't supposed to exist.
Dr. Whitehouse's point is, even if you want to believe NASA/GISS (and the scientists who collect satellite temperatures suggest there's reason not to) it's a big so what.
