Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. While I do make mistakes, I try hard to do my analysis thoroughly, and to make sure my data are correct (old habits die hard!) Also, don't ask me why I called it "Volewica". It's too late, now.

BTW, clicking on most charts will produce the original-sized, i.e., bigger version.

Fiddling with the data

In response to the evidence that the world is warming, the climate change denialists have accused the scientific community of fiddling with the data.  Of "the biggest science scandal ever".  This piece from the Guardian rebuts this specious rubbish.

This video by the founder of Berkeley Earth, who was a skeptic (in the proper sense of the word) is very telling.

And this one talks about the adjustments meteorologists make to past data to compensate for changes in the geographical locations of weather stations.

And finally, the long term global temperature chart, with and without adjustments.  As it turns out, without adjustments, global temperatures have risen faster than the adjusted number.  How we laughed.
