Eaarth

In Eaarth, Bill McKibben brings a less optimistic view change. He states at one point he states that while previous generations have believed global climate change was a problem for their grand-children to deal with, it is actually a problem our parents should have. 550 parts per million of carbon-dioxide was believed to be the magic number, the number that we couldn’t cross without major changes to the earth. Well, as Mckibben says, we haven’t been through global warming before, so it really isn't a surprise that the number is actually 350, and we've already surpassed it. McKibben suggests a slight change in the name of our planet renaming it Eaarth due to the subtle, but dramatic changes that have already occurred, ar4e occurring, and will occur. He states we cant go back, that we can minimize further damage, but can't take back what we've done. His new name is supposed to always remind future generations that we've changed our home.
