His sea level claim is bunk.
There are 1000's of hometowns that have a substantial warming trend to his that he claims does not.
I probably already wrote about it in this thread somewhere but I'll repeat it anyway. Suffice to say that we have seen a major regime shift in our summer weather pattern along the entire east coast of Florida. It is apparent at Titusville, Melbourne, Vero Beach, all the way down to Miami. Records going back to the late 19th century and the whole system just shifted in one jump in the late 1990s and early 2000s. The shift is consistent with changes in rain events up into the eastern 2/3s of the US in the summer. Big blocking high pressure is parking over the western Atlantic and the temperature anomaly aloft is capping our convection and trapping moisture at the surface. Our nights have gotten a lot warmer in a very short period and that moisture when advected up onto the continent is producing big convective rain events; a lot of them. This isn't a one off summer or two. It is > 10 consecutive summers during which we go the entire summer without the low temperature reaching the 100 year average and with dozens of days setting "record warm" minimums. I've lost track of the number of days that the temperature doesn't go below 80F at all during the entire day along the east coast of central and south FL. We don't get continental air masses down here in summer. Our daily low is dictated by the temperature at the 500 millibar level and how that affects our diurnal convection. Abnormally warm temps in the mid troposphere cap our convection and we bake in onshore winds blowing across abnormally warm coastal waters. It is obviously a bit more complicated than that but that is the way it is averaging out.
