That's 'Latin' for: It’s not the heat, it’s the humidity, because that's exactly true for the ice ages. And, Ophiolite, this is why I know that the global warming theory is wrong. Working on these papers: Ice Age, Flickering Climates? Part 1 Stable isotopes in Ice Cores Part 2 Oceanic Clathrate Destabilisation and Precipitation Part 3 Precipitation and the Mammoth Mega Fauna Extinction Part 1 Stable isotopes in Ice Cores It’s not the heat, it’s the humidity Abstract In the quest for the origin and causes of the Pleistocene Ice ages, the analysis of deep drilled ice cores reveal strong spikes in the heavy "water"isotope ratios (dD, d18O) in the last ca. 0.5 Mya. As isotope ratios are dependent on temperature. Consequently these spikes were attributed to sudden dramatic temperature changes, known as flickering climates. Here we model the seasonal behaviour of isotopes in precipitation which gives a clear indication of a mechanism for how those spikes have reacted to precipitation changes instead, which is backed by ice core evidence of the annual snowfall. This would refute the "flickering climate" hypothesis as being sharp temperature changes, and this would eliminate its alleged support for the current climate change projections.
