Croll revisited: Why is the northern hemisphere warmer than the southern hemisphere?
The question of why, in the annual mean, the Northern Hemisphere is warmer than the Southern Hemisphere is addressed, revisiting an 1870 paper by James Croll. We first show that the ocean is warmer than the land in general which, acting alone, would make the Southern Hemisphere warmer because of its greater fraction of ocean. Croll recognized this and thought it was caused by greater humidity a...
متن کاملCroll Revisited : 1 Why is the Northern Hemisphere Warmer than 2 the Southern Hemisphere ?
7 The question of why, in the annual-mean, the Northern Hemisphere (NH) is warmer than 8 the Southern Hemisphere (SH) is addressed, revisiting an 1870 paper by James Croll. We 9 first show that ocean is warmer than land in general which, acting alone, would make the 10 SH, with greater ocean fraction, warmer. Croll was aware of this and thought it was caused 11 by greater specific humidity and ...
متن کاملAre reptile and amphibian species younger in the Northern Hemisphere than in the Southern Hemisphere?
A previous analysis of molecular phylogenies suggested that intraspecific diversification had occurred more recently in temperate-zone Northern Hemisphere reptiles and amphibians than in Southern Hemisphere taxa. Here, we test potential explanations for this pattern. We examined published phylogenetic analyses, derived from genetic sequence data, to generate two estimates of the age of species:...
متن کاملHighest Treeline in the Northern Hemisphere Found in Southern Tibet
Determining the upper treeline is certainly one of the most interesting research challenges in comparative high mountain research. Careful compilations (Hermes 1955; von Wissmann 1961; Schickhoff 2005) have documented that the highest treelines in the northern hemisphere are found on the eastern declivity of the Tibetan Highlands. However, regional and global synopses of upper treeline altitude...
