Paul Clark, (the WFT guy) has introduce a plethora of new data sets to play with. This will make land to land/ocean comparisons much easier. I recommend all interested parties to go and take a look. You can start here. I also recommend all read his about/home page. http://www.woodfortrees.org/ I think it is important to understand where the information is coming from. If you clicked on the first link offered, you’ll see this graph…….
I was going to try and tie this into a more coherent statement, but I’ve got to run off for a bit, so, I’m just going to present some graphs from Paul’s new offerings. Oceans cooling? UHI verified?
The WTI, is a conglomerate of the other four data sets….. GIS, HadCrut, UAH, and RSS. So, what does this plot mean? It could mean a lot of things. First, and most obvious, is the thought that the BEST temps don’t properly reflect the global temps. This is probably true, remember BEST is land only. So Mr. Clark has given us the land coverage for the other data sets for comparison. Not only that, but we can also compare GIS total to GIS land, UAH total to UAH land, and so on. What do we find if we do that? Well, here’s the HadCrut total to land comparison.
Land covers right at 30% of the globe. Here we see the land temps are pushing the global temps up. Let’s look at a satellite set.
(I used the offset for easier comparison.)
Of course, this tells us a lot about what happened 30-20 years ago, and doesn’t tell us much about what is occurring at the near present….. lets look…..
That’s strange, I don’t remember Hansen telling us that the oceans are actually cooling. I guess he just forgot to mention that. Lets revisit Mr. Clark’s first offering, and fast forward to the start year of 1991.
Recall, BEST is land only, the WTI is land and ocean from all the rest of the data sets. And recall that land is 30% of the globe. Moving forward to 2001.
Question, what does this mean about the ocean’s temp trend? What does this mean about the UHI of land observations? Are there other implications to this information?
I’ve gotta run.
