There has been some turmoil yesterday on the leaderboard of the U.S. (Temperature) Open and there is a new leader.
A little unexpectedly, 1998 had a late bogey and 1934 had a late birdie. (I thought that they were both in the clubhouse since the turmoil seemed to be in the 2000s.) In any event, the new leader atop the U.S. Open is 1934.
2006 had a couple of late bogeys and fell to 4th place, behind even 1921. I think that there’s a little air in the 2006 numbers even within GISS procedures as the other post-2000 lost about 0.15 strokes through late bogeys, while it lost only 0.10 strokes. It is faltering and it might yet fall behind 1931 into 5th place.
Four of the top 10 are now from the 1930s: 1934, 1931, 1938 and 1939, while only 3 of the top 10 are from the last 10 years (1998, 2006, 1999). Several years (2000, 2002, 2003, 2004) fell well down the leaderboard, behind even 1900. (World rankings are calculated separately.) Note: For the new leaderboard see http://data.giss.nasa.gov/gistemp/graphs/Fig.D.txt. The old data has been erased; by sheer chance, I had the old data active in my R-session but I can’t give a link to it.)
