Sentences with phrase «logarithmic relationship»
A logarithmic relationship refers to a mathematical relationship between two quantities where one quantity changes proportionally to the logarithm of the other quantity. In simpler terms, it means that one of the quantities grows or decreases at a slower and slower rate as the other quantity increases. Full definition
Detrended correlation analysis in the sample period 1958 - 2015 shows the expected logarithmic relationship between atmospheric CO2 concentration and surface temperature at an annual time scale.

The climate science is indisputable... the known physics requires that each tonne of new CO2 emissions will have a smaller impact than the previous tonne... there is no escaping the actual logarithmic relationship between atmospheric CO2 and global warming...
I assumed a constant logarithmic relationship of 3.96 w / m2 per doubling of CO2, but there are probably some very minor changes over that range.
So in summary, you are using the same, simple logarithmic relationship that holds for CO2, even though some of the other GHGs have different behavior.
The only way this relationship could be linear would be if an increase in airborne fraction cancels out the logarithmic relationship between CO2 concentrations and radiative forcing.
Despite the logarithmic relationship between CO2 and surface temperatures, atmospheric CO2 levels are rising so fast that unless we dramatically decrease our emissions, global warming will accelerate over the 21st Century.
He understood the logarithmic relationship between CO2 concentrations in the atmosphere and surface temperature.
So, the logarithmic relationship between forcing and CO2 conc is compensated by changes in ocean heat uptake efficiency and the fraction of CO2 that remains in the atmosphere.
However, in that case, the cumulative carbon would need to be increasing at a rate akin to an exponential and the temperature x GtC plot would still look like the logarithmic relationship of temperature to CO2 levels.
The logarithmic relationship between CO2 levels and global temperature was first presented way back in the 1930s by a scientist named Guy Callendar, and it is now widely accepted as science fact.
CO2 - induced anthropogenic warming ends up being close to linear, due to a near - exponential rise in atmospheric CO2, coupled with the logarithmic relationship between CO2 increase and temperature increase.
A logarithmic relationship can not saturate, and the relationship is expected to remain logarithmic over a wide range of CO2 concentrations above and below current levels.
At higher elevations, where the air is colder, this increase in moisture has a much stronger greenhouse effect, following a logarithmic relationship.
Based on this logarithmic relationship (still valid today) Broecker assumes a climate sensitivity of 0.3 ºC warming for each 10 % increase in CO2 concentration, which amounts to 2.2 ºC warming for CO2 doubling.
You state that «based on this logarithmic relationship (still valid today) Broecker assumes a climate sensitivity of 0.3 ºC warming for each 10 % increase in CO2 concentration, which amounts to 2.2 ºC warming for CO2 doubling.»
I certainly understand the logarithmic relationship — that's straight 2nd law stuff.
In fact, using the logarithmic relationship we saw before, 0.5 degrees over 36 % of the doubling would imply a sensitivity around 1.0.
