I have a new toy. Its one of the Global Climate Models that is being used to predict the future of Earth’s climate and the effects of global warming.
Originally developed by NASA Goddard in New York its simply called “model E” Its the same GCM used to prepare the IPCC report. You can learn more about it yourself here.
By today’s computer standards, this program is rather crude, as it has a lineage that goes back almost 30 years. It was written in FORTRAN. But, despite the old school mainframe programming language, it does represent a mountain of work and knowledge.
My intent here is to learn as much as I can about it, so that I can more intelligently comment on climate change predictions. I also plan to try some baseline tests with it to see if it models true when known parameters are kept static. By doing this, I’ll be able to see if the climate system calculations are bias free for a variety of parameters.
I’ve already done my first global climate change model run, and it took almost two days for the calculations to complete from years 1958 to 2058. So it will be slow going since I don’t have a Cray supercomputer at my disposal.
I can tell you that I’ve already found one big surprise, the CO2 and solar insolation datasets inlcuded only go to 1998, but much has been made of the last 9 years of “record high” global temperature observations by global warming proponents. I am in contact with the authors to see if I can get the datasets updated.
I’ll keep you updated on what I learn.
