GLOBAL DIMMING - TRAGIC END OF HUMANITY .RO sub.

Global Dimming - Tragic End of Humanity is a documentary from an episode of BBCs Horizon science programme, about Global Dimming, i.e. that less and less sunlight seems to be reaching the Earths surface.It also goes into the relationship between global dimming and global warming, and that the latter could actually be a lot worse than weve thought.

Global Dimming, a phenomenon caused by small particles from car exhaust and industry pollution that clings to the water droplets that form clouds.This causes the coulds to relfect more light and heat back into the atmosphere.That effect, alone, actually causes the temperature to fallBut since the atmosphere has gone warmer, this spells trouble for the near future.

There has actually been one factor cooling down the earth, while greenhouse gases have been warming it up.Without the particles clinging to coulds, the earth would be much hotter by now.
This is whats worrying the climatologists:We are getting much better at reducing pollution, but in doing so, we actually remove the particles that have been protecting us from up to 30-40% of the sunlight in some areas.

If we stop polluting, we will solve the greenhouse gas problem, but we will add the problem of clear skies, making the earth warmerThis can actually happen very fast, in a few years.Watch the doc. Its good.

Overall this is a film that demands action.It reveals that we may have grossly underestimated the speed at which our climate is changing.At its heart is a deadly new phenomenon.One that until very recently scientists refused to believe even existed.But it may already have led to the starvation of millions.Tonight Horizon examines for the first time the power of what scientists are calling Global Dimming.
