A human-induced hothouse climate?

[摘要] Hothouse climate has been approached or achieved more thana dozen times in Phanerozoic history. Geologically rapid onset of hothouses in 104–105yr occurs as HEATT (haline euxinic acidic thermal transgression) episodes, whichgenerally persist for less than 1 million years. Greenhouse climate preconditionsconducive to hothouse development allowed large igneous provinces (LIPs), combinedwith positive feedback amplifiers, to force the Earth to the hothouse climate state.The two most significant Cenozoic LIPs (Columbia River Basalts and much larger EarlyOligocene Ethiopian Highlands) failed to trigger a hothouse climate from icehousepreconditions, suggesting that such preconditions can limit the impact of CO2emissions at the levels and rates of those LIPs.
