 by Andrew Glikson The linear nature of global warming projections by the IPCC (2014 ) Assessment Report (AR5) (Figure 1) appears to take little account of stadial cooling events , such as have followed peak temperature rises in previous interglacial stages. The linear trends appear to take only limited account of amplifying positive feedback effects of the warming from land and ocean. A number of factors cast doubt on IPCC climate change projections to 2100 AD and 2300 AD , including: The flow of large volumes of cold ice melt water into the oceans, leading to stadial cooling effects, such as in the North Atlantic ( Rahmstorf et al 2015 ; Glikson, 2019 ) and around Antarctica (Bonselaer et al., 2018). Paleoclimate observations indicate that during the Pleistocene glacial-interglacial cycles, at least for the 800,000 years, every time temperatures reached a peak a sharp cooling followed ( Cortese et al. 2007 ). Amplifying feedbacks from land and ocean drive non-linear climate tr...
