Sentences with phrase «atmospheric feedbacks»

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.»

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.»

The term should be self explanatory, but just to be clear, Venus syndrome is a scenario in which climate and atmospheric feedback loops are triggered that can't be switched off.

It is concluded that atmospheric feedback diagnosis of the climate system remains an unsolved problem, due primarily to the inability to distinguish between radiative forcing and radiative feedback in satellite radiative budget observations.

Early work at GFDL relating to carbon focused on CO2 as a greenhouse gas and it's potential for doubling in response to human activities, through water vapor and other atmospheric feedbacks in the context of latitudinal, land - sea and other inhomogeneities influencing climate (e.g. Manabe 1968, 1986, 1987).

Conclusion # 2: There is absolutely zero empirical evidence from the most advanced and sophisticated scientific technology available that Co2 emissions produce a constant positive atmospheric feedback leading to an ever faster acceleration of global warming.

It indeed so far has followed the laws of physics and thus the temperature graph is mathematically a good fit for the expected effects of the current CO2 concentrations but not for professed «positive atmospheric feedbacks».

Therefore, the researchers» next step was to understand the relative importance of ice sheet, ocean and atmospheric feedbacks.

The influence of historical and potential future deforestation on the stream flow of the Amazon River — land surface processes and atmospheric feedbacks.

Berkeley Lab researchers Dev Millstein and Surabi Menon found that atmospheric feedback — such as changes in cloud cover or precipitation — does have an important effect, resulting in different amounts of cooling in different cities, but that cool roofs and pavements are still beneficial for combating global warming.
