Sentences with phrase «ocean warming ratio»

The land - ocean warming ratio covers a range of about 1.4 - 1.8 in models.

Paul S also noted that much of the NH / SH ratio comes from the greater land / ocean warming ratio in the NH than is generally modelled, which is another mystery.

«Somewhat counter-intuitively, a land — sea surface warming ratio greater than unity during transient climate change is actually not mainly a result of the differing thermal inertias of land and ocean, but primarily originates in the differing properties of the surface and boundary layer (henceforth BL) over land and ocean (Manabe et al. 1991; Sutton et al. 2007; Joshi et al. 2008 (henceforth JGW08), Dong et al. 2009) as well as differing cloud feedbacks (Fasullo 2010; Andrews et al. 2010).»

Second, the quantity of methane necessary to explain the carbon isotope ratio, as calculated by Dickens, would be much less than that required to warm ocean and atmosphere temperatures to the extent estimated by PETM temperature proxies and calculated by physical climate models.

As the area / volume ratio for the NH parts of the oceans is practically the same as for the SH, the surface heating (W / m2) must be larger in the NH parts, within the constraints of heat exchange via ocean and air currents (and partly by the difference in warming area in the tropics vs. the cooling areas in the higher latitudes)...

So warming the ocean does not preclude it from absorbing any extra CO2 from the atmosphere, all it does is change the partitioning ratio.

This partitioning ratio is temperature - dependent, meaning that if you warm the ocean it changes, albeit slightly.

Furthermore, the zonal means over land and ocean considered above are representative of much of the small differences in warming ratio.

NASA's «GISS» temp uses land and ocean - based thermometers which measure «different parts of the system [UHI affected parking lots, asphalt heat sinks, AC exhaust air vents], different signal to noise ratio [we bias toward warm stations], different structural uncertainty [we «homogenise» our data set to cool the past and warm the present to fit the global warming narrative].»

In any case Gavin admitted that the TLT should be at least 0.95 of the faster warming land surface record and left unsaid what the specific higher ratio to the heat - uptaking ocean's 70 % of the planet surface was.

Whatever happens to the isotope ratio the fact is that warmer oceans hold less CO2 and colder oceans hold more CO2.

Energy ratio: for example (because I'm not sure offhand what the best amount to use is), taking just 5 % of the ocean and the latent heat of increased H2O vapor and the heat needed to warm the air as calculated before, heating this up 3 K would take 872 ZJ (still mostly going to the ocean).

The reduction of phosphate - rich ribosomes2 in warmer oceans will tend to produce higher organismal nitrogen (N) to phosphate (P) ratios, in turn increasing demand for N with consequences for the marine carbon cycle due to shifts towards N - limitation.

Here, we present an explanation for time - invariant land — sea warming ratio that applies if three conditions on radiative forcing are met: first, spatial variations in the climate forcing must be sufficiently small that the lower free troposphere warms evenly over land and ocean; second, the temperature response must not be large enough to change the global circulation to zeroth order; third, the temperature response must not be large enough to modify the boundary layer amplification mechanisms that contribute to making φ exceed unity.
