As of Wednesday, Jan. 13, the area has experienced 12 consecutive days of below freezing temperatures — a new record.MEANWHILE, "GLOBALLY" THE TEMPERATURES HAVE BEEN HIGH:
National Weather Service Meteorologist Jason Hess said that it’s the length of the cold that is most significant.
“This is the longest stretch ever in 100 years of record keeping.”
A new daily record low temperature was set Sunday, Jan. 11, in the Crescent Communities, with the area reaching 17 degrees.
Since the beginning of January, temperatures have remained more than 20 degrees below normal. Temperatures normally should be up in the 60s during the day and the 40s at night, Hess said.
Recently, the highs have been in the 40s and the lows in the 20s.
IOW: GLOBAL MEAN TEMPERATURE IS AS MEANINGFUL AS CALCULATING YOUR SALARY IN MARTIAN CURRENCY.
Many people think that the globe must be terribly cold these days. We’ve seen huge cold snaps and snowfalls in Britain, Eastern parts of the U.S., Western Europe, Central Europe, China, Korea, and India where hundreds of people have frozen.
So these are almost all the important places, right? (At this moment, the speaker forgets that there are places such as Latin America, Australia or the Balkans which have been warm.) So the globe must be cool – cooler than average, people could think.
However, the daily UAH global mean temperature shows a different story. The early January 2010 was warm. And on January 13th, which is the latest day whose temperature is known, we have seen the warmest January day on their record. The brightness global temperature near the surface waswhich may not look excessively warm :-) but it is actually 0.11 °C warmer than the warmest January temperature recorded by UAH so far – which was on January 5th, 2007 (-16.47 °C). Of course, some alarmists might feel happy for a while. They’ve been afraid that the worries about a new ice age could escalate. And they’ve been saved: the global weather is warm again. The strong El Nino episode could have helped them – or someone else. It’s important that they’re saved. ;-)
T = -16.36 °C
However, there is another, more important consequence of these numbers. And it is the following: the global mean temperature is irrelevant for you and for everyone else, too. It didn’t help the hundreds of frozen people in India, the passengers whose flights were canceled, and millions of other people in the European, Asian, and American civilization centers.
If you actually draw the monthly data from 1979 to 2009 – the global ones and those in e.g. Prague – you will find out that the correlation coefficient is just 0.17 – well below the maximum possible value of 1.00. It won’t be much higher outside Prague, either. :-)
The Pythagorean average monthly anomaly in Prague has been something like 1.95 °C.
Imagine that you want to use the global temperature in order to improve the estimate of the temperature in Prague for a given month.
If you add the global anomaly and the expected local average temperature in Prague for the month, you will reduce the typical fluctuation from 1.95 °C to 1.92 °C or so – almost no change. The swings in the global temperature won’t visibly help you to improve the predictions of the local temperature.
So while it may be fun to watch the global temperature – a meaningless game that many people began to play in recent years because of the AGW fad (and yes, your humble correspondent only plays these games because others do, not because it is scientifically important) – it is very important to realize that the changes of the global mean temperature are irrelevant for every single place on the globe.
They only emerge when things are averaged over the globe – but no one is directly affected by such an average.
AND ASCRIBING ANY UPWARD CHANGE IN GLOBAL MEAN TEMPERATURE TO MAN-MADE CO2 IS EVEN MORE IDIOTIC.
