Sentences with phrase «equilibrium warming»
"Equilibrium warming" refers to the concept of a stable and balanced increase in the average temperature of the Earth. It refers to the point at which the amount of heat energy entering the planet equals the amount of heat energy leaving it, resulting in a consistent temperature rise. It is a measure used to understand the long-term impact of factors like greenhouse gas emissions on global warming. Full definition
While I'm posting (I can see how you guys get into this) I'm also very uncomfortable with your notion of «tacit knowledge:» it certainly seems to be tacit knowledge in the blogosphere that the chances of the climate sensitivity (equilibrium warming on indefinite stabilization at 560ppm CO2, for the non-enthusiasts) being greater than or equal to 6 degrees are too small to be worth worrying about (meaning down at the level of an asteroid strike).

So as a hypothetical, let's say that equilibrium warming per doubling is 2.4 C (which is in between Dr. Curry's «best estimate» and the IPCC's middle - of - the - road estimate of 3 C).
They had built the first completely correct radiative - convective implementation of the standard model applied to Earth, and used it to calculate a +2 C equilibrium warming for doubling CO2, including the water vapour feedback, assuming constant relative humidity.
The same methodology can not be applied for constraining TCR, as the linear relationship between LGM cooling and equilibrium warming does not hold for the transient model response.
IPCC overestimate temperature rise «The IPCC's predicted equilibrium warming path bears no relation to the far lesser rate of «global warming» that has been observed in the 21st century to date.»
Assuming the IPCC most likely climate sensitivity value of 3 °C for doubled CO2 (incorporating only fast feedbacks - remember, long - term sensitivity is even higher) is correct, these US emissions cuts by themselves would reduce the amount of equilibrium warming by 0.08 °C, from roughly 2.9 to 2.8 °C surface warming above pre-industrial levels.
This would have left the impression that equilibrium warming of Antarctica due to doubled CO2 concentrations should be about 3 °C, in very good agreement with what is predicted by the state - of - the - art climate models.
This would have left the impression that equilibrium warming of Antarctica due to doubled CO2 concentrations should be about 3 °C, in very good agreement with what is predicted by the state - of - the - art climate models.
The report offers likely ranges and best estimates of the equilibrium warming that can be expected from various levels of CO2 in the atmosphere:
In the interview, Dr. Denning also explains that this 0.8 degrees Celsius per Watt translates to an «equilibrium warming» of around 3 degrees Celsius per doubling of CO2 compared to preindustrial levels.
(or, more precisely, «When will this «equilibrium warming» of 3 degrees Celsius be fully realized?)
The equilibrium warming from doubling CO2 is not going to be 3 ° C, which might marginally be considered a problem, but closer to 1 ° C, which will be beneficial.
He also fails to indicate that: (1) some of the warming is being offset by sulfate aerosols that are also due to human activities, and (2) given the large heat capacity of the ocean, the realized warming lags the equilibrium warming that he calculates by several decades.
