Presentation at the Santa Fe Meeting entitled ” Unresolved Issues with the Assessment of Multi-Decadal Global Land-Surface Temperature Trends”

Our powerpoint presentation from the July 17-19, 2006 ” Santa Fe Conference on Global Warming and the Next Ice Age” is available,

Pielke, R.A. Sr., C. Davey, D. Niyogi, K. Hubbard, X. Lin, M. Cai, S. Fall, Y.-K. Lim, H. Li, J. Neilsen-Gammon, K. Gallo, R. Hale, J. Angel, R. Mahmood, and S. Foster, 2006: Unresolved Issues with the Assessment of Multi-Decadal Global Land-Surface Temperature Trends. 2nd International Conference on Global Warming and the Next Ice Age, Santa Fe, New Mexico, July 17-19, 2006.

This presentation is being written up as a manuscript for submission to a special issue of the Journal of Geophysical Research.

These presentations, and the associated paper, show that there remain a wide range of issues with respect to the development of spatially representative values of multi-decadal land surface air temperature trends. This is why we need to move from the use of a global average surface temperature trend to assess climate system heat changes (i.e. global warming or cooling) to the use of ocean heat storage system changes, as recommended in Pielke Sr., R.A., 2003: Heat storage within the Earth system. Bull. Amer. Meteor. Soc., 84, 331-335.
