Wow, there are still some real scientists over at NOAA.
2010 Russian Heat Wave
WTF would a bunch New Orleans amateur jocks know about it?
That is not what was said at all. What was said was that this was a very unussual event, one that was unprecedented. There is no definate way to state that the blocking was due to the warming, however, with all the other precipitation events that we are now seeing worldwide, it fit the pattern of "wider and wilder weather swings, with an overall warming'. It was unuassaly cold in this area last winter, but the summer was even hotter than average. So the overall average for the year, so far, is warmer.
2010 Russian Heat Wave
This current condition in global mean surface temperature is thus consistent with prior conclusions of the IPCC Fourth Assessment Report that "warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level". The IPCC Synthesis Report goes on to state that "most of the observed increase in global average temperatures since the mid-20th Century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations".
A comprehensive analysis of observed changes in extreme daily temperatures for the period 1901-2003 also reveals symptoms of a warming planet with a majority of stations over western Russia and eastern Europe (and also over Canada) showing significant increasing trends of warm daytime and warm nighttime temperatures.
Despite this strong evidence for a warming planet, greenhouse gas forcing fails to explain the 2010 heat wave over western Russia. The natural process of atmospheric blocking, and the climate impacts induced by such blocking, are the principal cause for this heat wave. It is not known whether, or to what exent, greenhouse gas emissions may affect the frequency or intensity of blocking during summer. It is important to note that observations reveal no trend in a daily frequency of July blocking over the period since 1948, nor is there an appreciable trend in the absolute values of upper tropospheric summertime heights over western Russia for the period since 1900.
From the beginning of the paragraph you quoted from..........

NOAA's about to be thrown under the bus as apostates.
Well yes, the warming is hardly responsible, solely by itself, for a 25 F increase in heat over a huge area of Russia and Eastern Europe. After all, the average increase is not yet 1 C. However, a changing weather pattern because of that increase cannot be ruled out. And considering the other weather events worldwide this year, it surely does fit a pattern of unusual events worldwide.
Daveboy needs to come out from under the rug.
Just your typical capitalist propaganda.
And your obvious answer to the report?
I admire the strength of your faith. Nothing shakes it.
