It’s a good idea to compile a collection of photos illustrating climate change. But the narrative needs to be drawn carefully. One reason the Colorado river does not run to the sea these days may be climate change, but another may be that we extract a lot of it for irrigation. All of it, in fact. :-)

There is a lot of evidence. Adding a sketchy case to a batch of strong cases, on the theory that more is always better, is a mistake. Denialists can fasten on that one photo and make a more convincing [not better, there are no good denialist arguments] case than without that gift to the other side.
