I saw a sobering report on "NOW" last night, and I am very frightened. Scientists believe that we will see a global climate change of 6-8 degrees in the next 50 years. It may not sound like much, but temps today are estimated to be only 12-15 degrees hotter worldwide than during the ice age. A rise of 6-8 degrees is an unheard of, never experienced global climate changge. A rise in temperature will impact everything and cause crop failure (less snow melt to irrigate the crops), more species of plants and animals to go extinct, cause a rise in sea level which can obliterate some countries in the South Pacific, and cause more natural disasters. It will be horrible unless we change our ways.

What scares me so much is that these estimates are conservative. It could actually happen at a much higher rate and be a lot worse. This is not something that will happen long after we and our children and grandchildren are dead. This will impact THEIR lives. My child and her future children will be living in this hot, dead world unless we do something about it. Shoot, even I will be still be around if I am lucky.
