Sentences with phrase «rather high climate sensitivity»

Hansen's model assumed a rather high climate sensitivity of 4.2 °C for a doubling of CO2.

Not exact matches

Rather, their analysis shows that if you compare the LGM land cooling with the model land cooling, then the model that fits the land best has much higher GLOBAL climate sensitivity than you get for best fit if you use ocean data.

(in general, whether for future projections or historical reconstructions or estimates of climate sensitivity, I tend to be sympathetic to arguments of more rather than less uncertainty because I feel like in general, models and statistical approaches are not exhaustive and it is «plausible» that additional factors could lead to either higher or lower estimates than seen with a single approach.

If climate senstivity to CO2 is eventually shown (rather than just assumed) to be close to the sensitivity to solar, I think a case can then be made that the GHG attribution should be equal or higher than the solar attribution, despite the large uncertainty in our knowledge of the increase in solar forcing.

What's new is that several recent papers have offered best estimates for climate sensitivity that are below four degrees Fahrenheit, rather than the previous best estimate of just above five degrees, and they have also suggested that the highest estimates are pretty implausible.

Finally, we have not yet taken note here of Shindell»14 «Inhomogeneous forcing and transient climate sensitivity» which makes a very strong case not only for the unexpected aerosol loading from China being the culprit for the divergence, but also, unfortunately, for the case that a rather high sensitivity is a logical consequence of that explanation.

Both short - lived and long - lived species appear to cause enhanced climate responses in the same regions of high sensitivity rather than short - lived species having an enhanced effect primarily near polluted areas.

The lack of an increase in the rate of warming is therefore a major obstacle for a high sensitivity to CO2, and strongly supports the view that Climate Sensitivity to CO2 (if any at all) must be sensitivity to CO2, and strongly supports the view that Climate Sensitivity to CO2 (if any at all) must be Sensitivity to CO2 (if any at all) must be rather low.

So the carbon cycle sensitivity to temperature should be more relevant than the climate sensitivity to CO2... or maybe not after all, considering that the ppm / C ratio around 280 ppm seems to be an order of magnitude higher when CO2 is a forcing rather than a feedback.

The lower value — which conforms rather more closely with mainstream thinking than the higher value yields an effective climate sensitivity of ca 1.5 deg K for a doubling of CO2, which gets fairly close to ZDM estimates using historical forcing, temperature and ocean heat data.»
