Conclusion: For a tipping point and / or runaway warming to be reached, and then survive, the anthropogenic global warming hypothesis demands that the lower troposphere warms in a consistent and accelerating mode, due to the hypothetical positive atmospheric feedbacks supposedly produced from fossil fuel CO2 emissions.

Paul Dirmeyer, a professor in the department of atmospheric, oceanic and earth sciences at George Mason University who was not involved in the study, notes: «Green et al. put forward an intriguing and exciting new idea, expanding our measures of land - atmospheric feedbacks from mainly a phenomenon of the water and energy cycles to include the biosphere, both as a response to climate forcing and a forcing to climate response.» (sciencedaily.com)
If more heat is transferred to the oceans than is accounted for by the models, that «is a negative atmospheric feedback, at least on shorter time scales.» (co2coalition.org)
