By the way, Phil, we (Tom Smith, Dick Reynolds, Jay Lawrimore and I) are in the process of revising our global temperature number approach. We've added in satellite data over the ocean. This tends to slightly cool 1998 and a couple other years, but 1998 the most (all the differences are in the Pacific 40-60 degrees S). We treat buoys and ships differently. As the buoys are reading colder than ships (which was first pointed out by the Hadley Centre I believe) this warms the recent record as more and more buoys come on-line. It looks like it will be a couple months before we have this all operational and completely tested and ready to make it public. The skeptics aren't going to like it one bit so we're making sure we have all our ducks and tests lined up and ready to show that this is, indeed, a better process and why. We've also improved the earlier record by using different size boxes and cut offs for when to use data and when not to which cools 1880 somewhat compared to our previous version, again with objective tests that clearly indicate why this is better. Just thought I'd give you a heads up on it. Tom P.
