Across the edges of the Indian Ocean, the amount of rainfall differs greatly. If it rains particularly hard in the Sumatran rain forest, the already arid region of East Africa is onset with drought. Researchers from the Biodiversity and Climate Research Centre (BiK-F), the California Institute of Technology, the Univerity of Southern California and the University of Bremen found that this cyclic, bipolar climate phenomenon has likely been around for 10,000 years. The pilot study, published in the Proceedings of the National Academy of Sciences (PNAS), sheds light on the climate system of a region whose rainfall patterns have a major impact on global climate. Therefore, this study is of special interest to climate researchers.
In the long term, changes in sea level were of minor importance to rainfall patterns in north western Sumatra With the end of the last Ice Age came rising temperatures and melting polar ice sheets, which were accompanied by an increase in rainfall around Indonesia and many other regions of the world.. In contrast, the plant wax record from the study site in north western Sumatra reveals similarly high amounts of rainfall during both the Last Glacial Maximum and the Holocene. The amount of rainfall during the past 24,000 years seems to be linked to the level of exposure of the Sunda Shelf and in particular to the specific topography of the western edge of the region, rather than to changes in deglacial climate boundary conditions alone. This is quite unexpected. Based on previous studies it was assumed that the entire region was much drier during the Last Glacial Maximum compared to present conditions, Niedermeyer concludes.

More evidence global warming "scientists" are smoking too much greenback hemp rolls.
” found that this cyclic, bipolar climate phenomenon has likely been around for 10,000 years.”
Pretty much destroys the CO2 ozone hole theory, gas guzzlin SUV’s, cow farts and all other high methane producing organisms.
i.e. the “experts” are still figuring out how climate works.
