[Gasification] NOW Temperature Monitors Report Widespread Global Cooling

[Greg and April]

The point is, is that it goes both ways - depending on what sources that are 
used, and
remember, for skewed distributions, the mean is not necessarily the same as 
the middle value (median), or the most likely (mode).

OTOH, when 3 out of 4 well known and respected weather/climate centers, that 
previously showed data that "proved' global warming now show a global drop 
in temperature that documents the equivalent of a 10 yr flat line rather 
than an increase in temperature ( using the same resources as previously 
used to document increases in temp ), and all 4 show the single largest 
change in temperature ( that happens to be a drop ) even documented.

Remember, that historically, drops in global temperature, happen to greater 
degree in change and in less time that it takes for it to go up, so a 10 yr 
( or more ) average is a better indication of total climate change than a 3 
or 4 yr pattern.

Now, I have to ask, " How many times ( and how frequently ) to we have to 
see a drop like this to say this is a climate change and not a part of 
normal variation? " and " How many weather / climate centers have to report 
this, until we have a consensus that a downward trend is happening or that 
there has been little real upward trend? ".

Scientists have seen the temps increasing since the end of The Little Ice 
Age, around the late 1800's, but I have yet to see any data as to what the 
mean temp of the earth should be ( geologically speaking of course ) - it's 
quite possible that we are currently on the lower side of average and still 
need to go up another 5*-6* F to meet a statistic ( the reverse is true as 
well ) - the question also comes up on if there is such a thing as "normal" 
climate when it is always changing anyway.

As for the LaNina, issue - perhaps it's time for scientists to start looking 
closer at ocean currents ( and solar forcing ) as bigger climate factors 
than previously thought, and if that is so, man made causes would be less of 
a factor.    We will learn more in the next 2-3 years if predictions for 
another record high temperature year due to current and sun activity come 
true ( or not ).

Sure. Why not. One can find lots of places where temperatures are
falling. It might even lead one to believe that global cooling is
occurring - until one learns about global mean surface temperature:

"The year 2007 tied for second warmest in the period of instrumental
data, behind the record warmth of 2005, in the Goddard Institute for
Space Studies (GISS) analysis. 2007 tied 1998, which had leapt a
remarkable 0.2°C above the prior record with the help of the "El Niño of
the century". The unusual warmth in 2007 is noteworthy because it occurs
at a time when solar irradiance is at a minimum and the equatorial
Pacific Ocean is in the cool phase of its natural El Niño-La Niña cycle."
