Reports that the geological record of erosion indicates a fourfold increase in global sedimentation rates during the past 5 million years merited a global explanation. Explanations offered include an increased rate of mountain formation and global cooling.

Increased erosion associated with the rise of the world's great mountain ranges has been held to be the cause of a prolonged episode of past climate cooling. That connection is now brought into doubt.

Prof Jack D Ives discusses the aftermath of the global climate-change summit in Copenhagen.

The Oku-Kom highland morphological and human stronghold of West Cameroon with rich volcanic soils has attracted farmers and breeders thereby rupturing the mountain ecological equilibrium through slope gulling and mass movements. Overwhelmed, the indigenes adapted unsuccessful regreening approaches but without slope gradient considerations.

How do climate fluctuations affect DDT and hexachlorocyclohexane (HCH) distribution in the global scale? In this study, the interactions between climate variations and depositions of DDT and HCH in ice cores from Mt. Everest (the Tibetan Plateau), Mt. Muztagata (the eastern Pamirs) and the Rocky Mountains were investigated. All data regarding DDT/HCH deposition were obtained from the published results. Concentrations of DDT and HCH in an ice core from Mt. Everest were associated with the El Nino-Southern Oscillation. Concentrations of DDT in an ice core from Mt.
