I don't think that many here (including myself) have the technical background to discuss the physics of a very complex subject like climate change, but anybody around my neck of the woods can see the effects of climate change simply by walking to one of our nearby glaciers. They have retreated within human memory. Places that were covered with ice year-round when my parents went hiking are now ice free in summer. This is aside from other data, such as Seattle regularly setting temperature records.

But on the other hand, the ice cream in my freezer is frozen and it still snows in the winter, so climate change is a hoax!
