Sentences with phrase «cooling effects produced»

Let me try to be more explicit: if you want to assume (or, if you prefer, conclude) that aerosols produced by the increased burning of fossil fuels after WWII had a cooling effect that essentially cancelled out the warming that would be expected as a result of the release of CO2 produced by that burning, then it's only logical to conclude that there exists a certain ratio between the warming and cooling effects produced by that same burning.

One of the things I'm having trouble with is the uncertainties of aerosals and their effects on cooling, or the possibility of volcanic eruptions producing particles that result in cooling.

It is conceivable that aerosol effects (which includes «smoke») could also affect the lapse rate, but the aerosols tend to warm where they are located and depending on the composition, cool below — this gives an impact that — if it was a large factor in the tropical mean — would produce changes even larger than predicted from the moist adiabatic theory.

Note to reporters: a scientist's willingness to make predictions of the future is an indication of the current level of understanding of the science; for example Hansen et al predicted that Pinatubo's eruption in 1991 would produce a significant aerosol cooling effect, and they were right; but would anyone be willing to predict that La Nina (assuming conditions set in) will result in a record hurricane season this fall?

I'm pretty sure you can get the grey version of that into a strat - cooling / trop - warming situation if you pick the strat absorbers right, but Andy is certainly right that non-grey effects play a crucial role in explaining quantitatively what is going on in the real atmosphere (that's connected with the non-grey explanation for the anomalously cold tropopause which I have in Chapter 4, and also with the reason that aerosols do not produce stratospheric cooling, and everything depends a lot on what level you are looking at).
