one issue I have with the graphic posted by ValentineWeather is it shows a very large global cool down in 1991
but I have not seen anything else like that in other data
e.g
http://climate.nasa.gov/
only shows a 0.1C decrease around that time
and not an over 1F drop like that graphic shows

the video in this blog is very informative and well presented (but long)

Skips a bunch of pages....

In my boredom, I started going back through some charts I've been keeping for the last 5 years of daily highs and lows.  I started checking on records available from our local WFO; High, Low, Lowest High and Highest Low.  I went over my chart and color coded each record over the 4 complete years I have 2013, 14, 15 and 16.

I found 42 record daily lows or lowest highs and 42 record highs or highest lows.  I was not expecting to find equal counts.  Notably most of the cold numbers were in '15 and most of the warm numbers were in '16.

I didn't dig into things like how much the records were different from normal, etc. or how they were clustered together, if at all.  Many of the old records (both warm and cold) were long ago, 1940s-1960s.

Probably doesn't mean a thing, but I found it odd that the count was so equal.

Banners, tags, widgets, etc. are why I have Signatures turned off.

In terms of climate - no, it doesn't :)

Climate = infinity mean.

Weather = daily ± variances.

When doing any sort of climate analyses or drawing conclusions in terms of longterm trends we only look at stations with at least one normal period (30 years) of good quality measurements.

Yes, but the trend, how dynamic it is etc. can tell you something for at least a few upcoming decades - you are right, we cant tell much about what will be in 500 years :)

no one is saying the climate has not changed lots in earths past
but it has been relatively stable, globally, for the last 50,000 years
it is currently warming at a relatively fast rate (compared to how the global mean temperature has been for 1000's of years in the past)
that is the problem, the speed of warming: nature is having a hard time adapting/keeping up

Obviously, some people can not 'see' a tongue-in-cheek "scale-of-magnitudes" time-lime comparison when it's posted (wink,wink).
