I saw something on TV recently about global dimming (no, not people's IQ dropping!!!
), where particles from pollutants are blocking the light & heat from the sun which in turn lowers
the temperature on the surface, and, used as an example to prove this, the days that followed 9/11 showed an increase, by only a few degrees, in surface temperature in the US due to the thousands of flights being grounded. So basically, if we suddenly stop using fossil and other inefficient fuels, then we could actually further increase the temperatures of the Earth as the CO2
levels will still be causing the greenhouse effect!!! 8O
We'd need to reduce the amount of CO2
in the atmosphere (a good idea is replanting trees that have been cut down in the rainforests), then gradually
phasing out old style fuels in favour of newer, greener fuels and energy sources.
It's a bit like our fishtanks, if we added too many fish in one go, then the ammonia would spike which could end up killing off the tank's inhabitants until the filter bacteria caught up and cleaned up the ammonia produced...
But anyway, that's just the info I've seen on the issue, my only interpretation of it is the fishtank scenario....
