==Comparisons to present climate change== The extremely rapid, centuries-long timescale of carbon emissions and global warming caused by pulses of CAMP volcanism has drawn comparisons between the Triassic-Jurassic mass extinction and [[anthropogenic global warming]], currently causing the [[Holocene extinction]].<ref name="AnthropogenicScaleDegassing" /> The current rate of carbon dioxide emissions is around 50 gigatonnes per year, hundreds of times faster than during the latest Triassic, although the lack of extremely detailed stratigraphic resolution and pulsed nature of CAMP volcanism means that individual pulses of greenhouse gas emissions likely occurred on comparable timescales to human release of warming gases since the [[Industrial Revolution]].<ref name="VolumeRateCO2" /> The degassing rate of the first pulse of CAMP volcanism is estimated to have been around half of the rate of modern anthropogenic emissions.<ref name="AnthropogenicScaleDegassing" /> Palaeontologists studying the TJME and its impacts warn that a major reduction in humanity's carbon dioxide emissions to slow down climate change is of critical importance for preventing a catastrophe similar to the TJME from befalling the modern biosphere.<ref name="VolumeRateCO2" /> If human-induced climate change persists as is, predictions can be made as to how various aspects of the biosphere will respond based on records of the TJME. For example, current conditions such the increased carbon dioxide levels, [[ocean acidification]], and [[ocean deoxygenation]] create a similar climate to that of the Triassic-Jurassic boundary for marine life, so it is the common assumption that should the trends continue, modern reef-building taxa and skeletal benthic organisms will be preferentially impacted.<ref>{{Cite journal |last1=Singh |first1=Pulkit |last2=Lu |first2=Wanyi |last3=Lu |first3=Zunli |last4=Jost |first4=Adam B. |last5=Lau |first5=Kimberly |last6=Bachan |first6=Aviv |last7=van de Schootbrugge |first7=Bas |last8=Payne |first8=Jonathan L. |date=March 2023 |title=Reduction in animal abundance and oxygen availability during and after the end-Triassic mass extinction |url=https://onlinelibrary.wiley.com/doi/10.1111/gbi.12533 |journal=Geobiology |language=en |volume=21 |issue=2 |pages=175–192 |doi=10.1111/gbi.12533 |pmid=36329603 |bibcode=2023Gbio...21..175S |hdl=1874/427044 |s2cid=253303479 |issn=1472-4677|hdl-access=free }}</ref> The end-Triassic reef crisis has been specifically cited as a possible analogue for the fate of present coral reefs should anthropogenic global warming continue.<ref name="PandolfiAndKiessling2014">{{cite journal |last1=Pandolfi |first1=John M. |last2=Kiessling |first2=Wolfgang |date=April 2014 |title=Gaining insights from past reefs to inform understanding of coral reef response to global climate change |url=https://www.sciencedirect.com/science/article/abs/pii/S1877343513001826 |journal=Current Opinion in Environmental Sustainability |volume=7 |pages=52–58 |bibcode=2014COES....7...52P |doi=10.1016/j.cosust.2013.11.020 |access-date=12 December 2022}}</ref>
