Broecker, W. S., and G. H. Denton. January 1990. "What Drives Glacial Cycles?" Scientific American 262, no. 1:49. A discussion of how changes in the earth's orbit could lead to massive reorganization of ocean-atmosphere circulation patterns that determine climate.

Davidson, Keay. 1996. "Winter in Paradise," Earth 5(1):20-23. During the Ice Age, the tropics may have cooled much more than we previously believed. How might man-made climate change affect these areas?

Fernau, M., et al. October 1993. "Review and Impacts of Climate Change Uncertainties." Futures 25, no. 8:850. Uncertainties about the amount and rate of change due to human activities hinder policymaking. This article analyzes the sources of these uncertainties and offers no-regrets measures that we could undertake now.

Graedel, T. E., and P. J. Crutzen. September 1989. "The Changing Atmosphere." Scientific American 261, no. 3:58. A good overview of the atmosphere and how greenhouse gases might affect it.

Graham, N. E., and W. B. White. June 1988. "The El Niño Cycle: A Natural Oscillation of the Pacific Ocean Atmospheric System." Science 240, no. 4857:1293. Proposes that ENSO cycles are an oscillating system regulated by baronic, subsurface Kelvin and Rosby waves.

Horgan, J. March 1993. "Antarctic Meltdown." Scientific American 268, no. 3:19. Although glacial ice melts faster in a warm climate, increased evaporation and precipitation replenish glaciers faster as well. Different speeds at which glaciers flow and calve off icebergs may have a strong impact on sea level.
