I'll go ahead and say what others will not on Global Warming!

"The bad news just got worse: A new study finds that reining in greenhouse gas emissions in time to avert serious changes to Earth's climate will be at best extremely difficult. Current goals for reducing emissions fall far short of what would be needed to keep warming below dangerous levels, the study suggests. To succeed, we would most likely have to reverse the rise in emissions immediately and follow through with steep reductions through the century. Starting later would be far more expensive and require unproven technology." [more on this at Science Now]

The problem is people, pure and simple. Way, way too many to be precise!  In October 2011,mankind has hit the seven billion mark and shows no sign of slowing. If you really want to save the planet, we need to see very large numbers of men, women and children to perish! That would bring about the fastest and surest correction to what ails this world. As a better alternative, we need to work furiously together as a world to; reign in population growth, learn to get along together and get really, really frugal for about one or two centuries.... Pick one and good luck! In the end, Mother Nature will make a correction of her own, perhaps after most of the species of this planet are long gone. Not a book I would want to read to the end! Just a thought....
