In Conference

I am sitting in a teleconference about the Paleoclimate working group right now. They're discussing the climate simulations (right now) about the Permian climate simulations. This one is especially tuend towards the Permain carbon cycle. They have an interesting transition in the presence of sea ice that's pretty dramatic. There is sea ice and then...there isn't. They're working out why still but its rather interesting.

Anyways, here's the agenda:

Interesting stuff. This isn't just a mild interest. I'm considering another challenge shot and I am checking out the science applications. I want something that is cutting edge - partially because I like working with these people and also because I can help them along by providing some CPU cycles. I helped along the hurricane scientist significantly by providing him with charge free cycles in prep for the demo. He stated that a paper ought to be submitted to Nature as a result.


They're fighting over the exact model for the carbon cycle right now. One of the climatologists came out and demanded to know why the Permian simulations are not using the CCSM biogeochemistry working group. The project leader is defending madly by stating that the processes that are important on a yearly to even millenium time scales are different than those on the tens of millenia or millions of years. It's interesting. There's also an argument about the role of muds and how to simulate them in the carbon cycle. also rather interesting. Some feedback is going to be given to the CCSM community.
