If the data goes from negative to positive you could argue that the linear trend is increasing.

However, when you fit a straight line you should first be sure that the data represent something that has a linear trend. You can use least squares to fit a straight line to a sine wave or a parabola. Needless to say, any inferences you might draw will most likely be erroneous.

This is a problem with how people perceive mathematics. It is only a model, an analogy. It is not reality. You still need the basic understanding of reality to apply the right piece of mathematics.

Relating to hundredths of degrees?

That's (trends in temperatures) what science has been using as a "baseline" to show "Global Warming". The trend is flat when you consider the last 32 data points especially in the last 25 data points where it has really flattened out. The numbers do not oscillate (move above and below) much from the mean of 47 (last 25 data sets). It's about an even split above and below the mean so the trend is currently flat.

What each row of 10 relates to linear progression? You could normalize the extreme and means. Or better yet simply have a frequency of occurrence for a normal year. The latter isn't visualized in computer model with accuracy, or consistency. It breaks down to weather.

Hmmm...I just thought latency data sets. Yep I could post those in order and there's not a human on the planet that could understand it.

Is this one line of numbers or 5 lines? I see 5 lines, so I will answer as such.

First line it is rising

Second line is stable

third line is rising

forth line is falling

fifth line is stable

It would seem you are actually asking a none climate question i.e. maths, and just went with the auto section pick rather than use the quite simple to use manual option to pick the right section.

The auto system is quite dumb and quite often tries to put climate questions in other sections as well, it just picks out words in your title and compares them to words used most often in different question titles in various sections.

Or has the increase stopped?

-11, -15, -3, -7, -16, -9, 5, -17, -11, -22,

5, -4, 2, 12, 18 ,-1 , 17, 2, -2, 5

18, 24, 14, 29, 28, 9, 10, 18, 33, 23

35, 51, 30, 30, 42, 51, 50, 42, 50, 49

50, 39, 49, 50, 45, 47, 50, 48, 51, 47

45, 48, 52, 50, 43, 40, 44, 40, 48, 51

There is another hundred data points before the beginning that are all negative, and generally around -20 at the beginning.

There is clearly a rising trend in the early part.

Would you say that it is still rising because the highest 31 data values are in the last 32 points?

Before anyone asks why this belongs in this section, you should know that Yahoo recommended it, while not recommending it on questions that say 'global warming'.
