DESCRIPTION:\n\nEARTH AWARENESS and CLIMATE CHANGE REALITY FOR SCIENCE FANS\n\n\nThis 
 evening’s program will feature a film by Alder Stone addressing earth’s 
 current climate change.  It is Part III of a film he has created to explain 
 natural processes of the earth including climate change.  In this third 
 Part, "Why Large-Scale Climate Change Cannot be Stopped," he illustrates 
 why and how our current anthropogenic climate change is likely to be 
 abrupt, what scientists call a “Type II” climate change.  This is not 
 the smooth and gradual warming of the planet, allowing us humans plenty of 
 time to adjust — “Type I” climate change.  This is the catastrophic 
 jump of the planet from our present unstable climate state to a much hotter 
 but stable climate state of the sort that occurred 55 million years ago in 
 the PETM geological period.  Alder Stone’s film covers these 
 issues:\n\n\nClimate states:  We are not in control of Earth’s 
 thermostat\n\nEarth’s climate changes abruptly at tipping points\n\nCO2 
 levels are far higher than normal & accelerating\n\nCO2 residence time:  
 Even with zero emissions, the earth will still heat up\n\nMethane:  A 
 sleeping giant is waking up\n\nLag time:  Even after the gases stabilize, 
 the earth will continue to heat up\n\nMelting ice:  Why the poles are 
 heating 2X – 3X faster than elsewhere\n\nHeating oceans and unhappy 
 algae\n\nForests are switching from carbon sinks to carbon sources\n\nAs 
 yet there are no negative feedback processes to offset positive 
 feedbacks\n\nAerosols and global dimming:  Are we already hotter than we 
 think?\n\n \nWheelchair accessible around the corner at  411  28th  
 Street\n\n$5 donations are requested\n\n
