Taking into account the range of uncertainty, since 1000 ad the temp has increased .25 of one degree?

That's a good point.

However, remember that this is an average number. And it looks to me like about a .60 degree change, given the last reading. Even a .25 degree change is quite significant in terms of climate change. Finally, the most disturbing portion of the graph is the trend during the industrial age. The fluctuations are on a very steep upward trend.

Not incidently, the trend on this chart lines up quite nicely with the oil usage/peak oil charts I've seen.

Oh and.... ;)

I also want to point out that the degree of uncertainty is narrowing, the closer you get to the present. Obviously, the most recent readings have a very low level of uncertainty.

It looks like we are getting warmer.
If I can hang on to my North Augusta property long enough, it may be beachfront some day!

Good point about the narrowing range of uncertainty.
