UPDATE – GISS LOCATIONS AND GLOBAL NIGHTLIGHTS KML DATABASE FOR GOOGLE EARTH NOW ONLINE! Thanks to data provided by Steve McIntyre and conversion skills provided by Barry Wise, we now have the first ever interactive global mapping tool for nightlight ratings and GISS stations worldwide that encompass USHCN and GHCN station locations. Download it from the surfacestations website here […]
My post on Lampasas,TX has created quite a stir when Atmoz, a climate scientist unknown person at the University of Arizona, tried to demonstrate that the temperature spike shown in the GISS data at Lampasas, TX, was not due to the relocation next to a building and asphalt parking lot, but rather some problem with […]
The http://www.surfacestations.org project continues to collect new stations, though we could certainly use more help in the midwest, particularly Kansas, Nebraska, Oklahoma, and Texas. This NOAA USHCN climate station of record #415018 in Lampasas, TX was found to be tucked between a building, and two parking lots, one with nearby vehicles. According to the surveyor, […]
Hansen et al 1988 reported that they expected extra warming in the SE United States, a theme that was mentioned in his testimony in Washington in summer 1987. Hansen et al 1988 stated: there is a tendency in the model for greater than average warming in the southeastern and central U.S. and relatively cooler or […]
Hansen et al 1988 noted very sensibly that there were radically different approaches to some physical problems in GCMs and looked forward to the “real world laboratory in the 1990s” providing empirical information on these conundrums. One such conundrum were temperatures offshore Antarctica. They noted that their model showed a strong warming trend in sea […]
During our discussions of the differences between Hansen Scenarios A and B – during which the role of CFCs in Scenario A gradually became clearer – the absence of a graph clearly showing the allocation of radiative forcing between GHGs stood out rather starkly to me. When Gavin Schmidt re-visited the topic in May 2007, […]
Update: see further discussion here NOAA has a webpage on radiative forcing here, which includes a list of equations relating GHG concentrations to radiative forcing, substantially identical to the expressions in TAR. Below is a figure showing, on the left, the graphic at NOAA illustrating their calculation and, on the right, my emulation of this […]
This is a somewhat restated version of an earlier post seeking to understand the differences between Hansen Scenarios A and B. Rather than trying to clarify matters here, Gavin Schmidt posted over at Tim Lambert’s. In this morning’s post, I correctly identified that the difference between Scenarios A and B for periods up to the […]
In the various disputes over Hansen et al 1988, Roger Pielke Jr and NASA apologist Eli Rabett (who has been said to be occasional NASA contractor Josh Halpern) have each attempted to disentangle the forcing projections implied by Hansen et al 1988 – Pielke here and Rabett here for CO2 and here for other gases. […]
Update (Jul 28, 2008): On Jan 18, 2008, two days after this article was posted, RSS issued a revised version of their data set. The graphics below are based on RSS versions as of Jan 16, 2008, the date of this article, and, contrary to some allegations on the internet, I did not “erroneously” use […]
