What's flimsy specifically? That global temperature is going up? I think that's pretty well-established. You can look at the graphs, you can look at the record ice melt we get each summer, and if you really want to get scary, figure out how much higher the temp increase would be if a lot of that energy wasn't captured by the phase change of the ice melts. That the greenhouse effect exists? You can model that with 400-year-old physics.
