TL;DR: A review of the most recent literature on this topic can be found in this article, highlighting knowledge gains and research gaps since a similar previous review in 2009, and suggesting a number of research priorities for an improved understanding of how climate change may impact marine turtles, including: improved estimates of primary sex ratios, assessments of the implications of femalebiased sex ratios and reduced male production, assessment of the variability in upper thermal limits of clutches, models of beach sediment movement under sea level rise, and assessments of impacts on foraging grounds.

TL;DR: Results from natural nests and simulations show that the approximation of the thermosensitive period for sex determination to the middle third of incubation duration may create a quasi-systematic bias to lower temperatures when computing the average incubation temperature during this period and thus a male-bias for sex ratio estimate.

TL;DR: It is found that most loggerhead nesting populations will not be able to keep pace with a warming climate and warming will substantially reduce hatching success and induce a feminization of hatchlings, which may jeopardize their reproductive sustainability.

TL;DR: The differences among proxies are discussed based on the biological relevance of underlying hypotheses and the need for studies to accurately determine the thermosensitive period and to obtain appropriate estimates of embryo growth rate is highlighted to estimate marine turtle sex ratio.

TL;DR: It is found that both loggerhead marine turtle populations have similar thermal reaction norms for embryonic growth rate, highlighting that 12,000 yrs is not enough time for this species to adapt to specific thermal habitats and raises the question of the persistence of these populations in the context of rapid climate change.
