Glacial cycles and orbital inclination
Article Abstract:
The tilt of the Earth's orbital plane causes 100-kyr glacial cycles as revealed by studies of oxygen isotope ratio in the Specmap set of data from five sea-floor sediment cores. Extraterrestrial augmentation of dust in ice and sedimentary rocks detected via analysis of iridium provided proof for the role of orbital inclination in climate change.

Cycles in fossil diversity
Article Abstract:
Sepkoski's compendium of the first and last stratigraphic appearances of 36,380 marine genera is used to show strong 62(plus or minus)3-million -year cycles, which is particularly evident in the shorter-lived genera. Because of the high statistical significance, the contributions of environmental factors and possible causes are considered.
