Sentences with phrase «green house gas concentrations»

For example, if changes in temperature relate linearly to changes in green house gas concentrations in the upper atmosphere, that yields a diminishing marginal impact on temperature of increased concentrations due to the logarithmic forcing of GHGs.

Where I have a hard time with this is in accounting for the MWP and the LIA where Be10, as a proxy for solar activity, clearly shows high and low solar activity respectively during those time periods and green house gases concentration changes are not associated and mostly unchanged.

Not exact matches

It is not that I am trying to scare you, but the truth is that the concentration of green house gases has already passed the warning line; the climate system may get irreversible.

Now if CO2 was a really effective Green House Gas I would expect to see similar results: a) Clouds of (invisible) CO2 at altitude — as per 2) above — or at least increased concentrations.

QUestion: Since we can calculate within a factor of 50 % or so the stable temperature of the earth just by looking at the concentration of green house gases on the earth and no other factors it does not make any sense to me to talk of feedbacks as having any impact other than transiently.

Now thats about 1 % or less of what could be listed so to repeat your quite accurate assessment of the actual climate scientists and it was climate scientists who were being surveyed remember, who apparently believe that an impossible MORE THAN 100 % of global warming is due to human induced releases of atmospheric green house gas [GHG] concentrations
