Interesting report on the use of ship's records that will provide far more information about recent temperature changes than had been dreamed of previously. The article has only one drawback:
The discoveries "cast new light on climate change by suggesting that global warming may not be an entirely man-made phenomenon"
The problem here is that the writer obviously thinks that global warming is an entirely man-made phenomenon. Which, if this was the case, would imply that for all of geological history minus the last million years or less there has been no climate change!
But some progress was made today!
