DESCRIPTION:\nFilm evenings begin with potluck refreshments and social hour at  6:30 
 pm,\nfollowed by the film at  7:30 pm, followed by a discussion after the 
 film.\n\nGlobal Dimming\nby Duncan Copp\n\nThis documentary paints an 
 incredibly alarming picture of the Earth’s future wherein the average 
 global temperature may be 10 degrees hotter in 2100.  This skyrocketing 
 heat has not been predicted by scientists who study global warming.  It is 
 a new discovery and has only now become an issue of concern to the global 
 warming scientists.  This skyrocketing heat is caused by global dimming. 
 This effect has been lessening the effect of global warming and if the 
 pollutants are removed the temperature would rise by up to 10 degrees 
 worldwide.  Part of the research was conducted during the no-fly days just 
 after 911 when (almost) all planes were grounded and there were no 
 contrails.  The effect was first spotted by Gerry Stanhill, an English 
 scientist working in Israel.  Comparing Israeli sunlight records from the 
 1950s with current ones, Stanhill was astonished to find a large fall in 
 solar radiation.  “There was a staggering 22% drop in the sunlight, and 
 that really amazed me,” he says.  Intrigued, he searched out records from 
 all around the world, and found the same story almost everywhere he looked, 
 with sunlight falling by 10% over the USA, nearly 30% in parts of the 
 former Soviet Union, and even by 16% in parts of the British Isles.  
 Although the effect varied greatly from place to place, overall the decline 
 amounted to 1-2% globally per decade between the 1950s and the 1990s.  
 Gerry called the phenomenon global dimming, but his research, published in 
 2001, met with a sceptical response from other scientists.  It was only 
 recently, when his conclusions were confirmed by Australian scientists 
 using a completely different method to estimate solar radiation, that 
 climate scientists at last woke up to the reality of global dimming.  It 
 appears to be caused by air pollution.  Burning coal, oil, and wood, 
 whether in cars, power stations, or cooking fires, produces not only 
 invisible carbon dioxide (the principal greenhouse gas responsible for 
 global warming) but also tiny airborne particles of soot, ash, sulphur 
 compounds and other pollutants.  Even the most pessimistic forecasts of 
 global warming may now have to be drastically revised upwards.  This means 
 a temperature rise of 10°C by 2100 could be on the cards.\n\nWheelchair
