Opening with a sweeping statement directed at climate change skeptics, the summary declares that climate systems have already begun to change.
Unless action is taken, human activity could lead to "abrupt and irreversible changes" that would make the planet unrecognizable.
Will just one of the 10,000 delegates please explain to this simple bumpkin why these see-oh-two levels lead to "irreversible changes," but the historically higher levels of greenhouse gases were reversed and resulted in our current climate?
Is that question too hard?
Any time now.
I said "please."
If I rewrite this at the HIGH SCHOOL level can you answer?
