Meanwhile, the cost in terms of actual wasted capital and slowed growth in developed and in 3rd world countries, all in the name of reducing global warming, is so large as to be immeasurable.
- The figures reveal that from the beginning of 1997 until August 2012 there was no discernible rise in aggregate global temperatures
- This means that the ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996

Data presentation: A trend lesson
rasmus @ 23 March 2012
I just came across an interesting way to eliminate the impression of a global warming. A trick used to argue that the global warming had stopped, and the simple recipe is as follows:
Cut off parts of the measurements and only keep the last 17 years.
Plot all the months of these 17 years to get plenty of data points.
A good idea is to show a streched plot with longer time axis.

That’s exactly what you will find in the Daily Mail graph.
The realclimate.org author notes:
Climate change involves time scales of many years, and hence if emphasis is given to much shorter time scales, the trends will drown in noisy variations. This can be seen if we show annual mean anomalies (as shown below for exactly the same data), rather than the monthly anomalies
Whaddaya know – the annual means show that the warming trend is still there:

What really matters, though, is the anthropogenic temperature forcing, with the noise of El Ninos, volcanoes, and other natural cycles and events removed.
One of the weaknesses in Hadcrut is less-than-adequate coverage of the oceanic areas of the Arctic, a region where temperature increase has been more rapid than for the globe as a whole. As the record-smashing low in Arctic sea ice extent this year indicates, the Arctic is still cooking:

Not sure why the cite tag didn’t seem to take on my comment. Everything above the first link is from the link, as are the two sentences I attribute to the realclimate.org author.
Regarding this so-called ‘news’ -. You don’t read news. You read stuff you agree with. Just because somebody’s shit smells like yours, doesn’t mean it’s not still shit.
