There is no argument that there is climate change resulting in some warming.
The argument is over the cause of the warming. The unproven claim is that the warming is man made.
The melting of the Alaska Exit Glacier has been observed for 125 years but there is no evidence or proof that human action caused the glacier to recede two miles.
Of corse there is an argument against it, otherwise we wouldn't have all these Freepers reporting how much snow that had. There is ample reason to believe that much of the temperature data reported is just so much cr@p.
